Very helpful! It might have solved a memory issue (only half RAM usable, 8Gb hardware reserved) with my B450M PRO4 and R5 2600. Downgraded from 3.90 to 2.00 flawlessly. I hope it will never come back but for now I'm glad I've watched your video!
Did this solve your problem because i have the same problem with the same motherboard but my motherboard came with 4.20 out of the box so that is not fair because i have a ryzen 5 2600x which they said not to update so it might have been that
@@SKYLINED i couldn't fix it that way but what I knew is that mine had a broken pin so I took it to someone locally to repair it and they repaired it once they repaired it detected both 2x8 gb sticks so I had 16gb detected now. So just out of curiosity check your processor and see if it doesn't have any broken pins. If it does then that may be why not all ram is detected
@@juanpablo1542 the CPU is brand new and it used to detect the ram just hardware reserved half of it. After updating it doesn't even detect half anymore lol
Thanks so, so much for this solution! I had a massive performance drop after reckless 3.5 BIOS update (I read about issues with 3.x versions and Pinnacle Ridge CPUs too late). With this guide I downgraded BIOS to 2.0, 0 problems, everything works as intended. Specs: Ryzen 7 2700, Asrock B450M Pro4.
@@Gensith in short: I updated BIOS because I hoped that it will help with RAM stability but update caused a significant fps drop in games - something like 25%, definitely noticeable. Dunno why this happened, maybe this mobo's bios chip is to small to store one bios capable of running each gen of Ryzen properly.
@@kamilo.3468 damm dude i have also fps drop I hope this works, km kinda happy cos looks like the same problem I had AB350 gaming and a ryzen 5 1600, 8 RAM and a geforce 1660 everyting were great, I update to a b450 steel legend, ryzen 2700x, 16 RAM the same geforce and I have lots of fps droping it was better with my old pc I could not understand why,. This looks like a solution I hope this works
Sir, my respects, I updated my bios and some things stopped working, I was very desperate, thank you very much! From Mexico, you completely gained a fan!
Thank you! I just did this on a B450 Tomahawk with an R5 2600X from the latest version to v15. Weird fan curves are gone, it wasn't placebo, after I made the mistake of updating, temps and cpu fan speeds went batshit crazy, but it's all good now! Awesome tutorial.
Anyone with ryzen 3 3200g & asrock freeze problem that needed a hard reset. i followed this tutorial. bios from ver 7.0 straight to 3.3. fixed the issue. been looking for a solution online for ages. i cannot thank Spaceinvader One enough.
Thank you so much for uploading this video!! This information is so hard to find! Confirmed X370 Taichi downgraded from BIOS version 5.8 to 5.1 restores GPU passthrough. This is the first time out of 6 or 7 motherboards tested I've been able to get GPU passthrough working (the only other board I got working was an old AMD bulldozer setup). Thanks again, you are an absolute legend! I owe you a beer or beverage of your choice!
Here in 2024, on a MSI B350M Mortar i finally successfuly downgraded the BIOS and got rid of the random shutdowns, Sata Controller Problems , and all of the shiz i had with it, love you man and thank you so much 🎉
Thank you so much! Competent instruction saved my MSI A320 Bazooka from new BIOS (bad people didn't write a word about my A8-9600 being unsupported). The only difference is my "rom file capsule header checking" is disable, but took a chance and flashed it. Everything is back like before. Thanks again for the instruction and the files.
Thank you!!!! this method worked wonders!!! I had an ECS A320AM4-M3D with the latest BIOS and it didn't show video with an A8-9600 so I had to downgrade the BIOS (there are only two and the CPU is not listed oficially but yes fact checked compatible with the motherboard). I couldn't downgrade it with normal methods... but with this method: WORKED PERFECTLY. The A8-9600 is already installed in the motherboard and now works great!!! Thank you so much!!!
Thanks so much. This just saved me from changing the motherboard. I recently purchased a second hand x470 taichi and the former owner did update the bios to the lastest version. Now I was able to roll back. Much appreciated 👍
Chapeau and thank you so much. I got a Steel Legend with 3.20 preinstalled. My entire system was so instable with my 2700x and 32gb 3200mhz ram. I downgraded to 2.60 and everything works like a charm now. Spaceinvader One 10 Points - ASRock zero!
Absolute legend, saved my bacon on this one! Followed your instructions religiously and have managed to get my ASRock B450 Pro4 back to P1.8. Bit nerve racking for a noob like me but success!
I've got a new mobo, AsRock A320M-HD, and a old Ryzen 5 1600 AE. Mobo was 3rd gen ready. System worked, but with one annoying problem. I had a black screen everytime I turned the pc on after a shutdown. Then I needed to force shutdown and turn it on again, or restart, to get the system started properly. I downgraded to the last 1st gen bios using the video's procedure and now system works perfectly. Thank you so much!
Thank you so much, you just safe me bucks on an new MB. Bought a 5900x and 64GB Corsair LPX as an upgrade for my ASrock B450m HDV R4, powered by a 3600 and 16GB on Corsair LPX. Went to the latest Bios 10.01, thinking higher should be better, but guesed wrong. NO Boot, no POST, no nothing. Changing through the RAM, different banks, single double, CMOS reset... you name it. Nothing worked. Downgrade to 4.10, as the first Bios supported by ASrock foor the 5000 series was my last option and i shitted my pants. And it worked. Thanks again!
There is only 1 file showing up when I browse USB in shell and it's Bootx64.efi. Nothing else shows up? All files are showing in windows but my USB formatting isn't letting me do 4096 only 8k or 16, 32 and 64. I've tried 3 different USBs and they're all the same
Thanks for this, it worked a treat with my 2700X and X470 Taichi (which is essentially the same board as yours without 10Gb LAN). I was running BIOS v3.50 and it was of no benefit to the 2700X, boost clocks were lower for gaming workloads and they removed the Hyper BCLK Engine II settings after BIOS v2.00 so BCLK overclocking became pointless since I couldn't lock the PCIe bus speed at 100 MHz and turn up the core bus clock to 102 MHz anymore. I flashed back to BIOS v2.00 just like you did in this video and I'll leave it there unless I upgrade to a Zen2 CPU in the future.
Oh. I have Aorus x470 gaming 5 wifi mobo. And i get this: 4 - Error: ROM file ROMID is not compatible with existing BIOS ROMID. Does this means I can't downgrade?
Thank you so much for the fantastic overview. Only odd thing I encountered was another early numbered fsx: partition with EFI only in the root. I thought the drive was not formatted correctly since only one and only one file from the copied files in BOOT. This was just another partition/drive. I eventually found the correct one; though after I Rufus'd the flash drive again :) All well and BIOS downgraded. Your directions were excellent and much appreciated! Oh, and this was done since the latest X370 ASRock BIOS prevented 4 sticks of RAM from booting, boot loop, regardless of speed (i.e. 2133).
hello i did exactly as in the tutorial, same situation 100% identical to your tutorial, however when it is in the process: Erasing NCB Block ... I get the error: error 43, and stucks at 0%, Asus Prime B450m Gaming / BR with BIOS 2803 try to downgrade to BIOS 2202, thanks in advance.
@@iloveyouazula hello, finally after almost 01 year of brainstorming on this subject, I managed to downgrade my ASUS B450m Gaming/BR, it was with the BIOS AGESA 1.2.0.3 patch C(Bios 3211), I got the downgrade to the AGESA version 1.1.8.0 (Bios 2409), then I finally got the doengrade to the AGESA version 1.0.0.6 (Bios 2202) until finally everything worked out, from BIOS 3211 to version 2409 (downgrade) I I followed the video tutorial exactly the minimum details and it worked, after the downgrade from BIOS 2409 to BIOS version 2202 I did it through ASUS EZ FLASH3, it has a little golden tip and it makes the downgrade perfectly, everything is fine here , above BIOS 2409 my pc was having problems with DOCP profiles and also problems with USB outputs, plug and unplug errors intermittently, in BIOS version 2202 everything works perfectly, note: I have a first generation Ryzen, r5 1600, for this AGESA 1.0.0.6 suits me perfectly without any problem in DOCP profiles and no problem in the USB outputs, until finally everything is fine.
Imagino que você seja br. Eu tbm quero fazer downgrade para a 2202 a partir da 3211. Só pra entender corretamente, vc fez o downgrade primeiro para 2409 utilizando o vídeo e depois pra 2202 usando o próprio utilitário da asus?
Thank you so much for this. I managed to reflash latest BIOS to MSI Z390 Gaming Edge AC which had previously flashed bad BIOS from Carbon PRO AC by MSI service engineer. (They wanted me to send the board to RMA again to correct this). This vid helped me avoid all the hassle with taking system apart and sending the board to RMA.
I have followed all your steps, but have a small problem. In the shell, when I cd into EFI/BOOT and call the ls command, it only shows the Bootx64.efi file. All the other .efi files and the two .rom files (current and older BIOS files) don't appear when I call the ls command. I also realized that the file size of the shown Bootx64.efi file seems to be different/larger than it really is. My mobo is ASRock B450M-HDV R4.0 and my cpu is AMD Ryzen 3 3200g. I'm trying to downgrade from BIOS 3.70 to 3.30. Please let me know how I should go about this!!
This happens when you use "fs0:" or "fs1:" only since just like in the video, your drive isn't always on fs0. Try using each "fs#" from 1 to 10 or beyond if necessary, making sure to look at the directory each time with "ls" For example on mine, my flash drive was on "fs5:" since it is where the other files showed up (AMI files and your bios files) plus the size of the directory isn't just 1024MB but something like 8192MB since my USB drive is indeed an 8GB one.
Thank you SO much for making this, downgraded my fiances x470 Taichi from 3.50 to 2.00 with this tutorial with no issue. she has a 2700X that is not very stable with the newer bioses. I sent you a tip on PP. Thanks again.
Thanks for the guide, but it doesn't work for Motherboards of different brands with X570 Chipsetseries. After reading the rom you get the message - FFS Checksuns............OK right after that the message 3 - ERROR: ROM File size does not match ecisting BIOS Size -.- looks like they didn't want costumers to downgrade their BIOS if anything with the latest Version does not work. I wonder if that meets the rule's of law, but that's a different Question. I don't know if it work's with MSI, Gigabyte, Asrock anymore, but it didn't work with Asus definetifely.
To everyone looking at this now: DO NOT TRY THIS. Let everyone in this comment section stand as a warning. We all bricked our systems following this guide. Must be something with the new bios they’re using. Unless you want to buy a new mobo stay away!!!!
The same thing happened to me. The reason for this is probably AMD ROM armor. It's not a required feature, but it is generally being forced on consumers now. I recently had to RMA an ASRock motherboard because it was bricked during a BIOS downgrade. Interestingly, they put my board on the latest beta BIOS. It now offers an option to disable ROM armor, but I am not taking any chances...
I did everything you did in the video and everything works fine but at the very end it was on "Erasing Flash" and while it was erasing flash it failed and gave me an error which was:- 43 - Error :- Problem Erasing Flash. Now it is doesn't show anything on screen but it turn on. Please help nothing shows up but it gets power and fan is running too, please help 😭
Thanks nice guide, I was ready to pull the trigger on a 5600G to go on my b450 pro 4, but then read horror stories of all the new bios's breaking IOMMU. Of course the 5600G would require me to be on a new bios so now not sure. It seems whacked asrock have this problem on many of their boards?
Downgraded my Asrock x370 Taichi from 5.10 to 3.30, and when testing the dry run for bios.rom (3.30), I got the following message: FFS checksums ......... ok 4 - Error: ROM file ROMID is not comptaible with existing BIOS ROMID. I didn't care, and I ran your /P /B /N /K /X flags, and it successfully flashed. Thank you so much for the files and instructions. Also, I had a tough time finding my flash drive in the EFI terminal. A helpful way to possibly detect it is to type "map" as the first command. The last drive in the list ended being my flash drive. It was something like HardDiskp0b if I remember correctly, which I don't. But it wasn't a standard fsX drive.
Thank you so much, sir! This solution worked like a charm. Which is amazing, considering ASRock told me I'd either have to send the motherboard in or live with a janky BIOS forever.
So I just bricked my ASrock B450M Pro4. I bought it 2nd hand and the previous owner has upgraded it to latest BIOS version 5.30. On ASrock website they say they don't recommend the versions 3.60 and above for Pinnacle Ridge processors (I have Ryzen 5 2600X), so I thought I'd downgrade to version 2.00. Mainly because I was facing issues with RAM when setting up XMP (RAM is 3200mhz but no setting past 2400mhz would work). I followed your guide, step by step and everything went well. The dry-runs of the current BIOS and the to-be-downgraded-to BIOS were OK, exactly the same as in your video. Even the last step, the actual flash of the version 2.00 BIOS was OK - it erased, flashed and verified all the partitions - but it threw an error during the "Erasing NCB Block". Something along the lines of: 43 - Error - cannot erase block And at this point, I couldn't do anything. I knew rebooting would be death, so I tried at least flashing the current version (5.30) but that ended up in error as well. Tried reflashing the 2.00, same error as before. It's weird cause I see several people have downgeraded the same mobo without issues. Just so you know it's not a big deal as I got this mobo for very, very cheap.
@@basketballguy17 Unfortunately not. I don't think there is a way to recover the board without reflashing the buos chip with a specialized programmer and cable/clamp. Or getting another, non-corrupted bios chip and soldering it onto the board. It's basically it for me. I have come across good deal on asus prime b450 plus which works flawlessly, i am not having any memory issues with this ASUS board. I think while the ASrock boards look good, their BIOSes kinda suck, and I have seen/heard that from multiple sources.
@@tomasbalek5916 Aww man that sucks. I just bought my B450M Steel Legend brand new. Was running into the same problems as you where it shipped with a new bios that said it wasn't recommended for Zen+, and my ram was running at 2133. Guess I have to buy a new one.
@3:40 - So basically that's the only reason that can cause issue, just the fact that if you got the CPU difference. I am having X570 from Gigabyte, and I would like to roll back the BIOS by one version. I am having Ryzen 3700X and there have been quite a lot of BIOS versions since I bought. So realistically I should be able without issues to downgrade if that's the only reason why some manufacturers restrict downgrading?
Thank you! this is still a major issue in 2020. Nothing has changed. Running a first gen 1600 with a Strix B350-F. I should not of upgraded BIOS, but thought it'd be safe. I was wrong.
Thanks for the video. I updated to the latest bios(November)on my ASUS x570.. Turns out it slowed cpu boost clocks down.. This was after we got a performance boost from the September update. I tried your clearly stated procedure several times. I made absolutely sure I had the same downloaded bios of both versions, I made sure each version was named the same as you had suggested. I double checked, triple checked... But it still said the size was off. I remade flash drive several times, after downloading the proper versions of bios. I did a dry run of both and they both failed. I have an Asus x570 Gamer (plus) Wifi. The good news is I didnt brick my MB... But im stuck with this latest dog bios.. Now I guess I can just wait and hope they give the performance back. I have a 2700x.. But once again THANK YOU for your time and effort making this video. After this latest shit bios, I lost 100pts on cinebench15
Happens the same to me, when using trying to do the dry run the Asus x570 gamer plus (Wifi) all the time tells me the size is off no matter what bios ROM I try. Even the current one does not let me do it.
I too experienses the same result running the dry run on my ROG STRIX X470-F GAMING. 😞 Trying to roll back from 5837 to 5603 that was a stable BIOS for my setup. Thought I just leave a note for perhaps anyone else trying to downgrade as well. Thanks 4 all the great content Spaceinvader One, keep up the good work!

Hi, i followed every step you told, but when we do dry run i got rom capsule header checking disable but everything goes ok. What i can do now should i flash or not thanks.
Contrary to the other guy on here, mine also had that rom capsule header checking as disabled but proceeded with flashing it anyways and everything works just fine. So I don't see a reason why not to, unless of course your motherboard is a bit wonky or such. FYI I'm on a MSI board so ymmv.
@@jonathanparle8429 I don’t remember exactly which BIOS version. I only remember it was in the 3000s and it was a 3000 version down to I think the last 2000 version. I don’t think 4000 was out when I did this. Good luck

Wouldn't it be easier with some motherboards like the asus wrx80 to use the bios flashback feature where you plug in a usb stick and press and hold a button?
Hey guys! I fucked up rly bad, I have b450 and tried downgrading. Smth happened and my system doesn’t load at all. I can see fans working and motherboard led as well, but screen is just black. Tried clearing cmos, using mb cd. Also tried flashing back but realized Asus mobos need special port or button to support the utility for flashing back. So I have no idea what else I can do, any thoughts?
If you have the bios flashback button, you can try and use that. Download the correct bios you had and use the bios rename utility and put the file at the root of a usb stick and plug into the bios port. Press and hold the bios flashback button, and it should work.
Dood, I f**k*n love You! I got my usb keyboard / mouse working again after downgrading. Wtf is up these so called bios "upgrades"? Is it possible to not have certain 'features' broken after "upgrading".

Great video Ed. Gigabytes is a little weird in comparison. To downgrade I just need to put the bios I want to downgrade to on a usb stcick... but I also need to have every bios in between the current one and the one I'm intending to use. So downgrading is basically done one bios version at a time. Same thing happens when updtaing bios. Just thought I'd mention it. Had the same thing with Asus motherboards Have actually tried Unraid after updating bios on Asus A320, Gigabyte A320m and Gigabyte x470 and found the same problem and same solution.
Ah thanks, that's interesting Tim. I had a gigabyte x370 board once but never upgraded more than one bios version at a time, so didn't know that. Thanks for watching :)
Hi! I got a major bug with P4.70 on the x470 taichi ultimate. in fact all BIOS updates from p3.60 and upwards are making the system time stuck and P4.70 even kills the onboard NICs. only flashing back to P3.40 reverses stuff. also got another bug: the RGBLED settings are stuck and it doesn´t react to anything I enter. clear CMOS does nothing either. so can I use this method to do a clean flash from 3.40 to 4.70 ?
haha, I couldn´t wait and tried it already. good news, I am on P4.70 again. bad news: errors persist. so this clear cmos button on the backside doesn´t do anything. even with unplugged power cord and pressing the power button afterwards. does the taichi x470 ultimate has a cmos reset jumper which I don´t see?!
Very helpful! It might have solved a memory issue (only half RAM usable, 8Gb hardware reserved) with my B450M PRO4 and R5 2600. Downgraded from 3.90 to 2.00 flawlessly. I hope it will never come back but for now I'm glad I've watched your video!

This caused me so much frustration, thanks for deciding to make this video! I also have a X470 Taichi Ultimate.
Thank you so much for uploading this video!! This information is so hard to find! Confirmed X370 Taichi downgraded from BIOS version 5.8 to 5.1 restores GPU passthrough. This is the first time out of 6 or 7 motherboards tested I've been able to get GPU passthrough working (the only other board I got working was an old AMD bulldozer setup). Thanks again, you are an absolute legend! I owe you a beer or beverage of your choice!
Here in 2024, on a MSI B350M Mortar i finally successfuly downgraded the BIOS and got rid of the random shutdowns, Sata Controller Problems , and all of the shiz i had with it, love you man and thank you so much 🎉
Thank you so much!
Competent instruction saved my MSI A320 Bazooka from new BIOS (bad people didn't write a word about my A8-9600 being unsupported). The only difference is my "rom file capsule header checking" is disable, but took a chance and flashed it. Everything is back like before. Thanks again for the instruction and the files.
Thank you!!!! this method worked wonders!!!
I had an ECS A320AM4-M3D with the latest BIOS and it didn't show video with an A8-9600 so I had to downgrade the BIOS (there are only two and the CPU is not listed oficially but yes fact checked compatible with the motherboard).
I couldn't downgrade it with normal methods... but with this method: WORKED PERFECTLY.
The A8-9600 is already installed in the motherboard and now works great!!!
Thank you so much!!!
Thanks for the video.
Have downgraded my bios and have gpu passthrough working once again.
Hopefully this bug is fixed soon!
Thank you so much for this, i was able to get PCIe 4.0 working on my B450!! Next Gen here we go
And your voice isn't any boring :)
Thanks so much. This just saved me from changing the motherboard. I recently purchased a second hand x470 taichi and the former owner did update the bios to the lastest version. Now I was able to roll back. Much appreciated 👍
Hi Franz, you're more than welcome. Hey, that's great, glad you rolled back okay. Thanks for watching :)
Chapeau and thank you so much. I got a Steel Legend with 3.20 preinstalled. My entire system was so instable with my 2700x and 32gb 3200mhz ram. I downgraded to 2.60 and everything works like a charm now.
Spaceinvader One 10 Points - ASRock zero!
Absolute legend, saved my bacon on this one! Followed your instructions religiously and have managed to get my ASRock B450 Pro4 back to P1.8. Bit nerve racking for a noob like me but success!
Glad it helped Toby. Thanks for watching :)
Thanks! It resolved a big headache for me. I learned that higher version of a bios does not necessarily mean better performance.
I've got a new mobo, AsRock A320M-HD, and a old Ryzen 5 1600 AE. Mobo was 3rd gen ready. System worked, but with one annoying problem. I had a black screen everytime I turned the pc on after a shutdown. Then I needed to force shutdown and turn it on again, or restart, to get the system started properly.
I downgraded to the last 1st gen bios using the video's procedure and now system works perfectly.
Thank you so much!
Dude you are freaking AMAZING, the way you edit the video, the way you explain things, +1
Subscribed already +1 bell on!
Love u.
Thanks Yuriy
Thank you so much, you just safe me bucks on an new MB. Bought a 5900x and 64GB Corsair LPX as an upgrade for my ASrock B450m HDV R4, powered by a 3600 and 16GB on Corsair LPX. Went to the latest Bios 10.01, thinking higher should be better, but guesed wrong. NO Boot, no POST, no nothing. Changing through the RAM, different banks, single double, CMOS reset... you name it. Nothing worked. Downgrade to 4.10, as the first Bios supported by ASrock foor the 5000 series was my last option and i shitted my pants. And it worked. Thanks again!
There is only 1 file showing up when I browse USB in shell and it's Bootx64.efi. Nothing else shows up? All files are showing in windows but my USB formatting isn't letting me do 4096 only 8k or 16, 32 and 64. I've tried 3 different USBs and they're all the same
rom file size does not match existing bios size..... help me, the bios is the same
I followed your step-by-step procedure
Thanks for this, it worked a treat with my 2700X and X470 Taichi (which is essentially the same board as yours without 10Gb LAN). I was running BIOS v3.50 and it was of no benefit to the 2700X, boost clocks were lower for gaming workloads and they removed the Hyper BCLK Engine II settings after BIOS v2.00 so BCLK overclocking became pointless since I couldn't lock the PCIe bus speed at 100 MHz and turn up the core bus clock to 102 MHz anymore. I flashed back to BIOS v2.00 just like you did in this video and I'll leave it there unless I upgrade to a Zen2 CPU in the future.
Oh. I have Aorus x470 gaming 5 wifi mobo. And i get this: 4 - Error: ROM file ROMID is not compatible with existing BIOS ROMID. Does this means I can't downgrade?
Worked like a charm on MSI B450 Gaming Plus.
Thanks a lot for the workaround mate! Absolute legend!
Thank you so much for the fantastic overview. Only odd thing I encountered was another early numbered fsx: partition with EFI only in the root. I thought the drive was not formatted correctly since only one and only one file from the copied files in BOOT. This was just another partition/drive. I eventually found the correct one; though after I Rufus'd the flash drive again :) All well and BIOS downgraded.
Your directions were excellent and much appreciated! Oh, and this was done since the latest X370 ASRock BIOS prevented 4 sticks of RAM from booting, boot loop, regardless of speed (i.e. 2133).
Not work for me. Asrock b450m steel legend. /K not erase. Cannot flash existing bios, Error rom img layout. Now my mobo dead, it's bootloop. :(
hello i did exactly as in the tutorial, same situation 100% identical to your tutorial, however when it is in the process:
Erasing NCB Block ... I get the error: error 43, and stucks at 0%, Asus Prime B450m Gaming / BR with BIOS 2803 try to downgrade to BIOS 2202, thanks in advance.
same here, any solution?
@@iloveyouazula hello, finally after almost 01 year of brainstorming on this subject, I managed to downgrade my ASUS B450m Gaming/BR, it was with the BIOS AGESA 1.2.0.3 patch C(Bios 3211),
I got the downgrade to the AGESA version 1.1.8.0 (Bios 2409), then I finally got the doengrade to the AGESA version 1.0.0.6 (Bios 2202) until finally everything worked out, from BIOS 3211 to version 2409 (downgrade) I I followed the video tutorial exactly the minimum details and it worked, after the downgrade from BIOS 2409 to BIOS version 2202 I did it through ASUS EZ FLASH3, it has a little golden tip and it makes the downgrade perfectly, everything is fine here , above BIOS 2409 my pc was having problems with DOCP profiles and also problems with USB outputs, plug and unplug errors intermittently, in BIOS version 2202 everything works perfectly, note: I have a first generation Ryzen, r5 1600, for this AGESA 1.0.0.6 suits me perfectly without any problem in DOCP profiles and no problem in the USB outputs, until finally everything is fine.
Imagino que você seja br. Eu tbm quero fazer downgrade para a 2202 a partir da 3211. Só pra entender corretamente, vc fez o downgrade primeiro para 2409 utilizando o vídeo e depois pra 2202 usando o próprio utilitário da asus?
@@danield6182 if possible answer me
@@danield6182 I was in doubt how you renamed the boot file
Thank you so much for this. I managed to reflash latest BIOS to MSI Z390 Gaming Edge AC which had previously flashed bad BIOS from Carbon PRO AC by MSI service engineer. (They wanted me to send the board to RMA again to correct this).
This vid helped me avoid all the hassle with taking system apart and sending the board to RMA.
I have followed all your steps, but have a small problem. In the shell, when I cd into EFI/BOOT and call the ls command, it only shows the Bootx64.efi file. All the other .efi files and the two .rom files (current and older BIOS files) don't appear when I call the ls command. I also realized that the file size of the shown Bootx64.efi file seems to be different/larger than it really is.
My mobo is ASRock B450M-HDV R4.0 and my cpu is AMD Ryzen 3 3200g. I'm trying to downgrade from BIOS 3.70 to 3.30.
Please let me know how I should go about this!!
Yes same here only shows that 1 file nothing else it’s a pity was so excited
This happens when you use "fs0:" or "fs1:" only since just like in the video, your drive isn't always on fs0. Try using each "fs#" from 1 to 10 or beyond if necessary, making sure to look at the directory each time with "ls" For example on mine, my flash drive was on "fs5:" since it is where the other files showed up (AMI files and your bios files) plus the size of the directory isn't just 1024MB but something like 8192MB since my USB drive is indeed an 8GB one.
10:20 you can still continue if file capsule check is "disabled"
Thank you SO much for making this, downgraded my fiances x470 Taichi from 3.50 to 2.00 with this tutorial with no issue. she has a 2700X that is not very stable with the newer bioses. I sent you a tip on PP. Thanks again.
You are a godsend for making this video! Worked like a charm. Probably saved me an RMA!
Glad it worked Jeremy. Thanks for watching :)
I got the error flashing boot error or something like that in the last phase,i reset mi pc and no works,help pls its the mother corrupted?
Ive got 43 error when i tried to install bios 1.80. Now my pc doesn't start it goes for reboot every time. Mb asrock b450 gaming k4, ryzen 5 2600
Same here. Followed all the steps, and got the same error. Bricked.
I have the same problem. Did you ever figure out a solution?
@@Iris-s there is no solution. If your motherboard still have warranty you can try to replace it.
Hey ur motherboard is 🧱d
Actually worked on msi b350m gaming pro, thank u so much, no other ways worked before 🙏🏻
Thanks for the guide, but it doesn't work for Motherboards of different brands with X570 Chipsetseries. After reading the rom you get the message - FFS Checksuns............OK
right after that the message 3 - ERROR: ROM File size does not match ecisting BIOS Size -.- looks like they didn't want costumers to downgrade their BIOS if anything with the latest Version does not work.
I wonder if that meets the rule's of law, but that's a different Question.
I don't know if it work's with MSI, Gigabyte, Asrock anymore, but it didn't work with Asus definetifely.
Same on ASRock
To everyone looking at this now: DO NOT TRY THIS. Let everyone in this comment section stand as a warning. We all bricked our systems following this guide. Must be something with the new bios they’re using. Unless you want to buy a new mobo stay away!!!!
The same thing happened to me.
The reason for this is probably AMD ROM armor. It's not a required feature, but it is generally being forced on consumers now.
I recently had to RMA an ASRock motherboard because it was bricked during a BIOS downgrade. Interestingly, they put my board on the latest beta BIOS. It now offers an option to disable ROM armor, but I am not taking any chances...
Thank you, worked like a charm and you did an amazing job explaining everything!
I did everything you did in the video and everything works fine but at the very end it was on "Erasing Flash" and while it was erasing flash it failed and gave me an error which was:- 43 - Error :- Problem Erasing Flash.
Now it is doesn't show anything on screen but it turn on. Please help nothing shows up but it gets power and fan is running too, please help 😭
It’s over man you gotta get a new board
Thanks nice guide, I was ready to pull the trigger on a 5600G to go on my b450 pro 4, but then read horror stories of all the new bios's breaking IOMMU. Of course the 5600G would require me to be on a new bios so now not sure. It seems whacked asrock have this problem on many of their boards?
Downgraded my Asrock x370 Taichi from 5.10 to 3.30, and when testing the dry run for bios.rom (3.30), I got the following message:
FFS checksums ......... ok
4 - Error: ROM file ROMID is not comptaible with existing BIOS ROMID.
I didn't care, and I ran your /P /B /N /K /X flags, and it successfully flashed. Thank you so much for the files and instructions.
Also, I had a tough time finding my flash drive in the EFI terminal. A helpful way to possibly detect it is to type "map" as the first command. The last drive in the list ended being my flash drive. It was something like HardDiskp0b if I remember correctly, which I don't. But it wasn't a standard fsX drive.
OwN -3m-All oohemmgee thank you for this my brother.🙂
Thanks! Worked perfectly on ASRock B450 Pro4 rev1.01 with Ryzen 2600 from 3.60 to 1.80
Thank you so much, sir! This solution worked like a charm. Which is amazing, considering ASRock told me I'd either have to send the motherboard in or live with a janky BIOS forever.
So I just bricked my ASrock B450M Pro4.
I bought it 2nd hand and the previous owner has upgraded it to latest BIOS version 5.30. On ASrock website they say they don't recommend the versions 3.60 and above for Pinnacle Ridge processors (I have Ryzen 5 2600X), so I thought I'd downgrade to version 2.00. Mainly because I was facing issues with RAM when setting up XMP (RAM is 3200mhz but no setting past 2400mhz would work).
I followed your guide, step by step and everything went well. The dry-runs of the current BIOS and the to-be-downgraded-to BIOS were OK, exactly the same as in your video. Even the last step, the actual flash of the version 2.00 BIOS was OK - it erased, flashed and verified all the partitions - but it threw an error during the "Erasing NCB Block". Something along the lines of:
43 - Error - cannot erase block
And at this point, I couldn't do anything. I knew rebooting would be death, so I tried at least flashing the current version (5.30) but that ended up in error as well. Tried reflashing the 2.00, same error as before. It's weird cause I see several people have downgeraded the same mobo without issues.
Just so you know it's not a big deal as I got this mobo for very, very cheap.
I have the exact same problem! Did you find a solution?
@@basketballguy17 Unfortunately not. I don't think there is a way to recover the board without reflashing the buos chip with a specialized programmer and cable/clamp. Or getting another, non-corrupted bios chip and soldering it onto the board.
It's basically it for me. I have come across good deal on asus prime b450 plus which works flawlessly, i am not having any memory issues with this ASUS board. I think while the ASrock boards look good, their BIOSes kinda suck, and I have seen/heard that from multiple sources.
@@tomasbalek5916 Aww man that sucks. I just bought my B450M Steel Legend brand new. Was running into the same problems as you where it shipped with a new bios that said it wasn't recommended for Zen+, and my ram was running at 2133. Guess I have to buy a new one.
Same problem here I tried downgrading from 5.40 to 3.10 and ended up with same NCB error
@3:40 - So basically that's the only reason that can cause issue, just the fact that if you got the CPU difference. I am having X570 from Gigabyte, and I would like to roll back the BIOS by one version. I am having Ryzen 3700X and there have been quite a lot of BIOS versions since I bought. So realistically I should be able without issues to downgrade if that's the only reason why some manufacturers restrict downgrading?
Thank you! this is still a major issue in 2020. Nothing has changed. Running a first gen 1600 with a Strix B350-F. I should not of upgraded BIOS, but thought it'd be safe. I was wrong.
I wont try it out. If I list the data of fs0: I can only see bootx64.efi. The other files arent visible in my shell.
This saved me a lot of time/trial/error
Thanks and appreciate your video, very straight forward and it is worth watching
Thx, bro!!
Your detailed video and link to files helped a lot! And again, check the version of your previous BIOS, it may not support your CPU.
Thanks for the video. I updated to the latest bios(November)on my ASUS x570.. Turns out it slowed cpu boost clocks down.. This was after we got a performance boost from the September update. I tried your clearly stated procedure several times. I made absolutely sure I had the same downloaded bios of both versions, I made sure each version was named the same as you had suggested. I double checked, triple checked... But it still said the size was off. I remade flash drive several times, after downloading the proper versions of bios. I did a dry run of both and they both failed. I have an Asus x570 Gamer (plus) Wifi. The good news is I didnt brick my MB... But im stuck with this latest dog bios.. Now I guess I can just wait and hope they give the performance back. I have a 2700x.. But once again THANK YOU for your time and effort making this video. After this latest shit bios, I lost 100pts on cinebench15
Sorry to hear that it didnt work for you Paul. Thanks for watching .
@@SpaceinvaderOne The fault is all mine, for blindly upgrading bios. Great informative video though. Happy holidays!!!
Happens the same to me, when using trying to do the dry run the Asus x570 gamer plus (Wifi) all the time tells me the size is off no matter what bios ROM I try. Even the current one does not let me do it.
I too experienses the same result running the dry run on my ROG STRIX X470-F GAMING. 😞 Trying to roll back from 5837 to 5603 that was a stable BIOS for my setup. Thought I just leave a note for perhaps anyone else trying to downgrade as well. Thanks 4 all the great content Spaceinvader One, keep up the good work!

If you have the bios flashback button, you can try and use that. Download the correct bios you had and use the bios rename utility and put the file at the root of a usb stick and plug into the bios port. Press and hold the bios flashback button, and it should work.

Very nice! I didn't realize AMI had a tool for EFI shell now! Much better than having to create a freedos flash drive!
Yeah, it's very useful. I think the dos version hasn't been supported since about 2015 as well and they recommend this now. Thanks for watching :)
i have a ROG Strix X570-E Gaming and upgared today first time too Version 4002 from Version 2802 and now i have performance issuis in games .... i tried the metod like you show in your video but i cant see all files when i start to boot in the flash drive idk why
I have gigabyte 970A DS3P motherboard and cpu amd fx8320. It seems that cpu doesnt work properly ond FD (newest) BIOS version so i want to downgrade to the first version FA. How to do that? Can i use same way like in this clip?
What if it says : ROM FILE SIZE DOES NOT MATCH EXISTING BIOS SIZE
My "ROM File capsule Header checking ... disabled" is that ok?..
Great video Ed. Gigabytes is a little weird in comparison. To downgrade I just need to put the bios I want to downgrade to on a usb stcick... but I also need to have every bios in between the current one and the one I'm intending to use. So downgrading is basically done one bios version at a time. Same thing happens when updtaing bios. Just thought I'd mention it. Had the same thing with Asus motherboards
Have actually tried Unraid after updating bios on Asus A320, Gigabyte A320m and Gigabyte x470 and found the same problem and same solution.
Ah thanks, that's interesting Tim. I had a gigabyte x370 board once but never upgraded more than one bios version at a time, so didn't know that. Thanks for watching :)
Hi! I got a major bug with P4.70 on the x470 taichi ultimate. in fact all BIOS updates from p3.60 and upwards are making the system time stuck and P4.70 even kills the onboard NICs. only flashing back to P3.40 reverses stuff. also got another bug: the RGBLED settings are stuck and it doesn´t react to anything I enter. clear CMOS does nothing either. so can I use this method to do a clean flash from 3.40 to 4.70 ?
haha, I couldn´t wait and tried it already. good news, I am on P4.70 again. bad news: errors persist. so this clear cmos button on the backside doesn´t do anything. even with unplugged power cord and pressing the power button afterwards. does the taichi x470 ultimate has a cmos reset jumper which I don´t see?!
