I bought this a few years back, this little programmer made us so much money we literally ran our shop for months on the money we got programming chips with it, its my absolute favorite.... Merry Christmas from Zimbabwe 🇿🇼🇿🇼🇿🇼🇿🇼🇿🇼
@Ruben Chris Some people will attempt to update the bios on their motherboard and it will fail making the board unusable and most people will say it can't be fixed / it's bricked. If you use one of these programmers you can clear and refresh the bios and bring the motherboard back to life. Example: I bought a Z490 motherboard for $20 because it had a bad bios. I flashed the bios with my programmer and the board works fine now. I resold it for $100.
Sorin, that is very well explained how programming, and that you need Ampere, to burn something and not volt, and one should not change anything about the CH341A programmer, people always tend to complain without knowing anything thank you Sorin Merry Christmas to you and your family too, from Belgium
You are absolutely right, Sorin. A couple of years ago I bought one complete SVOD3, but this one was my very first programmer (BIOS chips only, of course). I had never modified it in any way, and it does work perfectly. The worst thig is the chip clip; it is really bad. You are luck, man! It does work for you in the video!.
I agree, the clips are terrible... I've had 2 sets from AliExpress and one clip worked almost flawlessly on half a dozen PC motherboard BIOS chips and the second set of clips was virtually useless I threw it away as it simply couldn't stay on any chip. If you need to program a BIOS chip urgently then it might be a good idea to order at least 2 clips and hope that one of then is good.
I have a few things to say. 1. Sorin explained nicely in the video that the chip will not fry because the current is not high on the pins and that is correct. And that Programmer is beautifully designed and does its job.. 2. as far as CH341A modification is concerned, it is not a matter of higher voltage in chip frying, but in data transmission on that pin. 5V (4.82V) and 3V (3.28V) voltage injection affects the data transfer pin (read-write) It is known that voltage and frequency affect data transmission (Example: higher frequency affects data transmission, incomplete transferred content on the chip can occur), which also happened to me, but not always. So it's not about frying the chip, but a higher voltage on the data transfer pin. There is a lot to explain depending on the use of the Programmer and its connections, i.e. the resistance of the accessories (Examples: a clip with a longer cable or the length of the cable by connecting to the chip) 3. You don't need to modify CH341A works perfectly. If you decided to modify, in my opinion, the best way was modified by Georgdev. You can look at (eevblog.com-forum-repair-ch341a-serial-memory-programmer-power-supply-fix) with this modification, you regulate 3V and 5V on the switch. when it is put on 5V switch it is in factory condition.. Sorry for my bad english writing, Regards..
I have a question If I need to reprogram a Lenovo Bios Chipset, do I need to purchase any program/firmware in some scenario where the exact firmware is not available?
But, the chip seems to be lowering the voltage to 3.2V when it detects a chip that requires 3.2V. It means the programmer is smart enough to change its voltage (on data pins too) accordingly. Therefore, you do not have to modify the programmer.
i really needed to understand this programmer before using it since i never used one and i found no videos about how to use it rather than showing it i mean i need to know all about it before using it and someone really did this and im just gonna subscribe
I am 62 and lack the funds to purchase a Microscope as I am weak sighted, but enjoy your videos so much as it just proves that the world needs common sense. Example: My wife programmed process controllers without Grade 12 maths and science. I did computer science, but branched into commercial systems. She used Fortran and I Cobol. We now look back after more than 40 years and laugh at ourselves. I was thinking in paragraphs and she was thinking in arrays. I later bit the bullet and went to college to learn C and logic mainly to understand my wife.😇😁
Luckily I've read a post on Reddit saying that no modification is required. Btw I thought exactly the same: a manufacturer can make a bad design, but this programmer has been around for a very long time, it cannot be possible to have all these "faulty" boards around now. Thanks for using your brain. The Internet is a good source for information, but this is an example of why everything must always be checked and not trusted straight away, you don't know who's on the other side. Let me share a trick to get usb ports connected right the first time: the eyes of the port must look to the sky. That's how it's easy to remember for me 😅
I know you are a busy Man, so I will keep this short. You have helped me learn a new skill with reflash my Son's Legion. This video, and a previous one about how Lenovo BIOS can just bite the dust, made me bite the bullet and give it a go. I could not find a bin file to download, so erased the chip, reinstalled the original files and Bobs your Aunties sister it started up. Thank you Sir, this thing cost me over £1k and Lenovo would not help in the slightest and wanted £1,200+ to repair it (I could have purchased a brand new one for that price). I will be sending you some cash at the end of the month for all the help you have been. Thank you kindly Sir, I wish you and yours Health and Happiness.
Phenomenal explanation, I bought the same complete one but I was years behind in studying how to program it now, I am an amateur but you have to check the bios IC datasheet and the clamp or socket have specific positions because usually these products do not come with good manuals.
Just purchased the Programmer from Amazon to make it a little easier for me to program the chips. I do have the means to air unsolder the chips but hopefully with this programmer this will cut the soldering step. Great video..... 👍
A great little programmer, the only two issues are speed (it’s a little slow) and the black peg/clamp is terrible. The pin are so hard to line up and get a good connection. I ended up buying the blue pegs which worked so much better! I have bought a faster (more expensive) version to speed things up. But the one you tested is a great device.
Wow, this is what I call an electronic class. Thank you, so much. I'm trying to restore a Steam Deck, and my gut says the problem is in the BIOS microchip. I connected the CH341a on it and it didn´t recognize it. Later on I discovered that the chip runs in 1,8v and I tried without the adapter. I was afraid I had burnt the microchip. Now I understand that this can't happen. Good thing is that I didn't read or write anything on the chip because it didn't recognize it. Now I'm waiting for the 1,8v adapter to come, and I'll test again. Hopefully, it will be recognized.
I can also confirm this. Used the black programmer to rewrite a 3.3V BIOS chip, actually twice (first with a wrong ROM, then with a working one). Everything went fine, the laptop works properly after that. Nothing burnt or got damaged. So no, you DONT need to modify the CHF341A programmer.
I have used this with success and have never modified it, as the seller from Alpress told me that no need to modify. I even sent him link which said it had to be modified. His answer was they have sold so many and no need. Trust me friend, he said lol. Good one and have a very happy festive seasons.
You are dead right! (electronic engineer). I already had one and I modded it as I was advised to. Damned thing just did not work at all. Reversed the mod and it started working!! The mod I did did nothing with pin 9. Pin 9 is the output of an internal LDO 3.3V regulator. So if you supply VCC with 3.3V this LDO reg has an output possibly below a critical value for function. The datasheet for the CH341A chip says to short pin 9 to VCC if used in this way. It is designed to work with 5V. I admit it is a bit unusual to design an IC with voltages above recommended maximums for programmable devices but the designers knew what they were doing.
Very informative! A non-low knowlege about ch341a programmer original voltage functions and behavior. Ty sir for sharing this knowlegeable video. God bless your household.
That little programmer repair me frozen bios on Lenovo G50 80 with Intel I5 processor which I sell later for 300€. Still use HP NC 6320 which had power on password for car diagnosis. Neat little programmer. I read and write everything with clip, no soldering.
I tried this exact method, verbatim, to read a MX25L3206E BIOS chip, using the same exact programmer, ribbon connector and orientation etc. It detected the right device, and even partially read the data, but stopped after only reading 6% of its contents. I disagree that it's impossible to kill the chip with 5v, because after this attempt, the supply is now being shorted to ground through the chip. Prior to detecting the device, the default supply was 5v.I think the safest method is to prevent the 5v completely, when reading or writing to MX25Lxxx, but obviously not for all EEPROMSs!
My boss bought one of this for us to use in the shop when we were just getting our feet wet with programming SPI chips and such - it paid for itself tenfold ! Soon we were fixing laptops and TVs with corrupted firwmare like there was no tomorrow.....and I never ONCE even thought about the voltage it used :))) It just worked :)) Ok, I never went as far as to program a 1.8v chip with it, but aside from those, 3.3v and 5v chips worked perfectly fine and to be fair, for a good while, I just assumed they ALL chips ran at 5v, until I looked at the datasheet for a 3.3v chip more carefully and had a "whoops" moment, realizing I've been pumping 5v into them for years on end :))) That's when I knew they can take it without a problem :)
The "Mod" refers to using the programmer for automotive stuff that requires 5v instead of c.a 3v in order to work. Modding them allows you to read/write 5v stuff. Hence "no need" to mod for laptop use - but need to mod for automotive use.
Sorin. When the BIOS is flashed, the serial number of the machine is lost or replaced with another incorrect one. There is a procedure for writing the serial number in the bios file.
Happy Christmas Sorin and Diana. Thank you for sharing your skills and experience. One hand washes the other, so one day, i will be able to repay you. Have a brilliant xmas with plenty of laughs, warmth and satisfaction that 100's of thousands of people are happier thanks to your videos. Cheers 🍻 🍷!
Great, I needed this on a bios for an old laptop that's a paper weight and its bios has been corrupted for years, I will try it, very informative piece here Sorin. watch your youtube channel all the time and never miss an episode. Greetings form an old Romanian from Sydney Australia that left Romania in 1960, I was born in Petroşani and still can speak a little Romanian, but I forgot how to write, so sorry that I can't write to you in Romanian as using google translate is just not on, keep the great work up but please stop the bogginess 😁😁😁 with not replacing capacitors 😁😁😁👍👍👍
TL866II+ is the cheaper one the works without issues and there are monthly software upadates ... I use this one only as a COM interface to program seagate disk paramaters ( smart etc etc )
I am absolutely new to bios chip rewrite but I have heard that we should always remove the cmos battery. Is that true? Thank you Sorin. Love your videos.
I have already used the NeoProgrammer V2.2.0.10 program on the black CH341 recorder, it is much better than the recording program that comes with it. Ja usou o programa NeoProgrammer V2.2.0.10 na gravadora CH341 preta, fica bem melhor do que o programa de gravação que vem nela.
Where do we get the software for it from? Could you please add Google Drive link so we can use the same software? - I'm currently using *NeoProgrammer* but it keeps crashing and nor always successful when writing to IC. - Thanks in advance.
Particularly on certain laptops (HP), when the programmer supplies power to the BIOS when still on the board the MB may try to initiate a startup. Of course the USB power source isn't nearly sufficient enough so the programmer can't communicate.
@@SerenoOunce You made a great point. When I connected the clips to an older MSI Z170 Gaming M7 motherboard that has a Power button it, the power button green LEDs suddenly turned on once I connected the clips to the Bios chip!! I'm a noob when it comes to electronics but I was a little confused when it happened. So what's going on? Is the programmer somehow giving enough power to the BIOS chip and it somehow spreads out to other parts of the motherboard?
I really enjoy watching your videos, they are full of very useful information. Unfortunately, you did not show how to use a 1.8V adapter in this video. I need to flash my laptop's bios, I've never done this before and I don't want to screw anything up. It's a Lenovo ThinkPad A485, there should be a 1.8V chip. Can you please make a video on how to use the 1.8V adapter? Thank you
I've tested it my self - especially I've bought a 1,8v adapter. The programmer software says "Chip not responding" - in 1.8 adapter, but same chip in same adapter works ok straight in CH341a, so what was the point to buy a voltage converter?
Regardless of current or being burnt, I will not have peace of mind if the data lines are pulled up above the Vcc of the chip being programmed. But thanks for your wonderful videos, I'm subscribed and do learn from them ...
@electronicsrepairschool Thanks for your videos, I'm just an electronics fan and I learn a lot, a pity they don't have the option of translating the subtitles for all the videos.
It is not valid to read voltage with a multimeter during programming. This is measuring the average voltage (including zeros) not the peak voltage. I know a lot of people who insist they have fried flash chips without the mod. I am wondering though, if there are different versions of the CH341A which have different output current limits? It is common for people to not connect the VCC line to the flash and to not power the target board for ISP. And they successfully program the device. In this case the entire chip will be powered by protection diodes on the input pins. It will need something like 20mA or more to successfully burn a flash, in which case the current from the data lines must be a lot greater than 1mA. Such currents at high voltages could fry a chip. I also disagree that it is current that blows up chips. It is power = voltage*current. Whilst a diode normally has about 0.7V across it this can vary considerably as the current through the protection diode changes. All they need to do to ensure protection is put current limiting diodes in the data lines. It is running at low speed
Nice instructions for CH341A. I have 2 chips on the board, it's dual bios, but the firmware file is just one. How to do it via USB programmer CH341A? well thank you
That means your motherboard has a backup bios chip if the first one fails or gets corrupted it will copy the contents from the good backup to the bad one and if your bios is still corrupted that means both of the chips are corrupted and you have to reprogram both

I tried this exact method, verbatim, to read a MX25L3206E BIOS chip, using the same exact programmer, ribbon connector and orientation etc. It detected the right device, and even partially read the data, but stopped after only reading 6% of its contents.

The "Mod" refers to using the programmer for automotive stuff that requires 5v instead of c.a 3v in order to work. Modding them allows you to read/write 5v stuff. Hence "no need" to mod for laptop use - but need to mod for automotive use.

Nice tutorial. I prefer desolder bios chip always. The programming bios chip when is soldered sometimes goes wrong :(
This is what I do. The clip does not do proper connection most of the time.
Particularly on certain laptops (HP), when the programmer supplies power to the BIOS when still on the board the MB may try to initiate a startup. Of course the USB power source isn't nearly sufficient enough so the programmer can't communicate.

soldering a 10v 470uf capacitor from GND to VCC fixed my problem. now the clip works flawlessly.... previously my test clip was not working.
Your a living legend
Yes, So lets talk about dealing with the W25Q64FW - 1.8V 64M-BIT.
I really enjoy watching your videos, they are full of very useful information. Unfortunately, you did not show how to use a 1.8V adapter in this video. I need to flash my laptop's bios, I've never done this before and I don't want to screw anything up. It's a Lenovo ThinkPad A485, there should be a 1.8V chip. Can you please make a video on how to use the 1.8V adapter? Thank you
You dont need a whole video to use the 1.8v adapter, you just have to aling pin 1 of the adapter with pin 1 of the programmer, its not that hard
and finally ordered. Many thanks
Happy cleared review, happy Christmas in advance ♥️
I've tested it my self - especially I've bought a 1,8v adapter. The programmer software says "Chip not responding" - in 1.8 adapter, but same chip in same adapter works ok straight in CH341a, so what was the point to buy a voltage converter?
Great video
I did the mod before your video but thanks for sharing your knowledge
i love this chip just add a 74ls244 between spiflash and the chip you can use it as level chifter with 2 regs 1.8 and 3.3 volt
Good luck sir 🎉
Happy Nativity Sorin🙏🧡💚
Super useful video, thank you very much!
nice to see you again man
great information do you have a link for the software your using..
Regardless of current or being burnt, I will not have peace of mind if the data lines are pulled up above the Vcc of the chip being programmed. But thanks for your wonderful videos, I'm subscribed and do learn from them ...
Mulțumesc Sorin
This is a great video we can use this.
Nice wish you a happy and Merry Christmas sir
you are a boss, sir. thank you
@electronicsrepairschool Thanks for your videos, I'm just an electronics fan and I learn a lot, a pity they don't have the option of translating the subtitles for all the videos.

@@suediem9315 Thank you, at the time of writing my message it was not possible to activate it, now I see that it is.
Sir, thanks for this video
I want to ask, what happens when the bios chip is not detected and it didn't burn?
It is not valid to read voltage with a multimeter during programming. This is measuring the average voltage (including zeros) not the peak voltage. I know a lot of people who insist they have fried flash chips without the mod. I am wondering though, if there are different versions of the CH341A which have different output current limits? It is common for people to not connect the VCC line to the flash and to not power the target board for ISP. And they successfully program the device. In this case the entire chip will be powered by protection diodes on the input pins. It will need something like 20mA or more to successfully burn a flash, in which case the current from the data lines must be a lot greater than 1mA. Such currents at high voltages could fry a chip. I also disagree that it is current that blows up chips. It is power = voltage*current. Whilst a diode normally has about 0.7V across it this can vary considerably as the current through the protection diode changes. All they need to do to ensure protection is put current limiting diodes in the data lines. It is running at low speed
which one did you buy?
What program you using? I hit the wall with mine... i have 1.3 which is looks difrent than what you show
awesome video. thanks for the explaination
Nice instructions for CH341A. I have 2 chips on the board, it's dual bios, but the firmware file is just one. How to do it via USB programmer CH341A? well thank you
That means your motherboard has a backup bios chip if the first one fails or gets corrupted it will copy the contents from the good backup to the bad one and if your bios is still corrupted that means both of the chips are corrupted and you have to reprogram both
Great video thanks merry Christmas
Merry christmas sorin 🎉
Sorin = perseverance ✔
5:05 Actually you can burn a CMOS transistor with a static electricity, which is just the high voltage.
Mrs. Sorin pin number 1 red wire should connect it on the gate ??
I use one of these for doing automotive eeproms and the 5v works great. The new version 1.7 has a voltage switch to make life easy
hey, im wondering, where they use these for automotive applications? im studying automotive engineering and you may help me to learn something new!
@@rul3s1232 ECM Programing, keys, mileage ect.
Perfect explanation..!
Is the ch341B any different from the ch341A?
the people who say you have to modify is people who are doing eeprom read/write on automotive immobilizer /speedo correction /airbag(srs) etc
Nice explanation !
Merry Christmas too all
