Thank you!!! I've been trying to factory reset for days using hardware buttons. I had no idea S21 had to plug into a PC. Thankfully I found your video, it worked first time... halalooya!! Tip if you havent got a pc - I plugged a charging cable with C connection at either end into my tablet and it worked!! Thanks again, I have literally gone grey trying to do this. Legend!!
you're welcome! Samsung made this change a few years back (with the OneUI 4.0 update, I think) and not many people were aware of it that's a great tip about the USB cable. I appreciate you sharing that information with the community If you're able to, please consider becoming a TH-cam channel member here - www.youtube.com/@ExplainingAndroid/join Or joining my newly created Patreon page here - www.patreon.com/ExplainingAndroid
Thank you for sharing this updated instructional! There are so many videos appearing as the topmost results of search engines that still go on with the old way of accessing recovery mode (which cannot be done).
So I got a wild card here. My s21 did some weird stuff during a forced update, started to overheat at 99% on install. Took about an hour of playing with the power button to power on, and worked despite me not knowing what made it turn on again. Second update came through a few weeks later, no overheating but the same issue with the power button. Device battery finally died despite my efforts to usually keep it charged above 10%, plugged it in to charge and it indicated it was charging on screen, woke up the next day and now it just won't turn on and I've been playing with it for over a week now. The screen lock functions worked fine through all this despite the power on issues. AT&T considered it "unresponsive" and basically told me to kick rocks when it came to a data transfer. New S21 arrived in the mail, and when connecting via USB C through the provided cord it will charge the old device, but due to the old S21 not powerimg on it seems a c to c transfer is put of the question. Can I potentially reboot it remotely via a PC ADB or an ADB software on the new device? Since I need to erase data before sending the old device in I may as well try, I just have a potato PC from 2007 and no 2.0 to C dongles.
if you can execute ADB commands on the thing, then the command "adb reboot" should work just fine or "adb reboot recovery" will reboot the phone and send it into Recovery Mode
@@ExplainingAndroid ahah! Cool beans dude. Every service center near me won't even claim to know about ADB so it's all on me to try. Even authorized sansumg service centers. Thanks for the pointers
@@ExplainingAndroid well I gave it a whirl but unfortunately despite accepting a charge from my other phone it didn't get picked up by the PC even with a dongle adapter. Thanks for doing what ya do though, seems like we need more android/Linux people out there to make working on em a bit more common.
I think this method no longer works with the latest March 2021 update? I just tried and it did not work in my case. However, it did work before I got the March 2021 update.
Really weird that samsung is making things difficult for people. Probably most owners want to sell their old phone for a new one. And have to do a "Factory reset". This is NOT a "customer first" service company. Really annoying. Thanks for good informative video.
Man, I just watched another video how to reset forgotten passwor and I tried maybe 50 times with power/volume up buttons. Than I saw this video and entered recovery mode from first time.
before updating to oneui 4.0, i can boot without plugging in the type c cable. But after updating to oneui 4.0 i cant boot anymore.... thanks to this guide i can now boot to recovery mode to wipe cache partition.. thanks a lot. the only problem left is refresh rate is stuck in 120hz even it is set to adaptive
Latest update UK version - Does not work. NOT yet found a way plugged into PC or not. up button or down or ANYTHING, also crazy ,even if it did work, if you were out & emergency & needed recovery (however unlikely) but sods law operates this way so very annoying & unnecessary!
I'm not sure. I've read that only certain things with a USB cable works and I don't have an OTG flash drive to test. If someone else has tested this, please let us know!
Sadkly this didn't work for a pretty new Galaxy S21 Ultra, and Samsung wonders why people switch to iPhones..... I shake my head in disgust at Samsung. But thank you for posting this video ! I tried all the steps shown, but it's stuck on a loop to green screen and download, with Chinese lettering, any button combos, press and hold, it loops right back to same screen.
this process may have been updated along with the release of the Galaxy S22. Check my channel for the "galaxy s22 recovery mode" video and see if that works for you
Nope, plugging into a PC doesn't seem to work any more with latest Android 13 on an S21 Plus. If the phone shows it's charging it won't work. According to another TH-cam video that has been true since Android 11 & 12, but I can't verify. What *did* work for me, following the other video's instructions, was inserting a headphone adaptor and then doing power and up-volume. Straight into recovery. Could you update your video please for others with the same issue. Thanks!
Mine won't even turn off without my PIN, which I've entered wrong at set up somehow. HOWEVER, I can use the DOWN volume and power to force the reboot to Recovery mode...why does Samsung keep changing things!!
yes! I've read a few comments that mention this as well. thanks so much for the feedback don't forget to hit the "Thanks" button on the video, if you can, and definitely join the channel membership area here th-cam.com/channels/nowc_KHgjVNj3Y-E-oQ8aw.htmljoin
Since the new update Samsung rolled out I keep getting that moisture is detected in my port therefore I am unable to plug into pc to clear cachd in recovery mode. Is there a work around?
Yes I have. It worked when I tried a way from other video. Switch off, then connect to pc and instantly before charging icon appears press power and volume up, then when Samsung logo appears release power button but keep volume up and then it finally appeared. What a hassle.
I've read that it can be a USB connected to many things. Possibly a pair of earbuds or something with a USB connector I haven't personally tested it but I think I do remember reading that it does work
My Samsung Galaxy S21 Ultra 5G was working very well with the Christmas decorations on there. I received a text message from a female hacker saying: I got your number and i hacked your phone. Few minutes later my phone started to act very strange than it got stuck on the boot loop. I went into the Android recovery mode to wipe out the partition than I get an error message at the bottom of the screen saying: [ libfs_mgr ]Error updating for slotselect. I select "Reboot system now" than my phone still were stuck on boot loop 😟 Can somebody please help me ? 😨 and is it because it was hacked ? 😨 I am crying 😰
somy phone is having the moisture detection problem, i dont have it linked to my pc and it is out of battery so i cant connect it to my new laptop. cheers samsung

6 minutes about pressing side + volume up buttons :D U should also write a book about it.
This recovery mode advice solved our problem with a repeated reboot cycling. Thank you!
Hello. How did you fix the repeated reboot issue.
@MohammedFarisjilmax I just followed the guys instructions, step by step, and it worked perfectly.
No problems since. Good luck

I'm on the latest updates for the S21 (March 18 2021) and this worked for me! Thanks. 😊
That's great to hear. thank you for the feedback :)
Thank you so much, been struggling with this for a couple of days now as other tutorials dont mention to connect the device to somewhere.
Thanks, it works on my S21+ Exynos

Power + vol ^ on startup, but release only the power button when the splash screen pops up.
Exactly THIS. You do not need to plug any cable into anything.
No need to connect it to a pc, not sure if is because the update, but now is the same way as older galaxy versions
that's interesting. which update are you on?
I have the newest update. I have to use the usb cable to get it work
It's the same way it's done on my Samsung Galaxy S20 FE 👍with Exynos 990.
that's interesting. the regular s20 (exynos) uses the previous method. I wonder what caused the changed for the 20 fe release
