A51: how to enter recovery with Android 11? - Samsung Galaxy A51 Questions & Answers

With Android 11, the vol+power button method no longer works.

Hi! With the phone turned off, connect the phone to your computer, immediately press the volume up + power button until the samsung logo appears.
Hope this works for you!!

you need to connect usb cable

I tried that, and then the phone asked me if I really want to install a custom ROM. The bootloader is not unlocked, all stock.
At least I got ADB working, so I could start recovery to clear the cache.

Try to hold all buttons of your phone down for about 10 seconds and then your phone should restart itself.
Force your device to reboot by holding volume down, home button and power button at the same time. Hold the buttons down until the device reboots.
From then you can attempt to flash stock firmware via Odin and then making sure that you have enabled OEM unlock in developer options and that you have the correct TWRP for your device (Check MD5, to make sure it isn't corrupted)
Didn't help!

Hey! How did you manage to solve the problem? I'm having the same issue.

How do I fix my OnePlus One’s bootloop?

Greetings of the day,
Hello everyone, I'm having a oneplus one 64GB phone that is not getting start, everytime i connect it with the charger it goes into a bootloop. Yes the phone was rooted and I was using a custom ROM with the default kernel. The issue started when I tried to reset the phone to battery settings. I think I somehow messed the kernel and now it is stuck in bootloop. The problem is that I can't connect it to my computer or put it in debug mode as it just restarts again. Any idea how to actually boot it so I can install the kernel and ROM again?

No, My phone is not getting on but whenever i am connecting it with my charger the phones goes in the Bootloop, and when i am connecting it to My PC while pressing Volume Up + Power Button Pc shows that the Unrecognized devices has been connected.
And i think phone is Hard Bricked. I have tried ADB software and one plus 1 drivers manually but it didn't worked too. I have tried minimal ADB too but it also didn't work.
Kindly let me know about it.

Volume UP + Power should boot in fastboot mode. Volume Down + Power should boot into recovery. First, try to boot recovery.

I have tried both, but nothing happens with it, Volume UP + Power shows the unrecognizable device is connected and Volume Down + Power does nothing it continues with bootloop .
Have you got Developer Options enabled?
Goto About Phone & Tap Build Number until Developer Options is activated. Goto Developer Options> Advanced Restart & enable the switch.
Press power button->Restart->Recovery.
It will now boot into Recovery.
Also have you tried keeping hold of power button whilst it bootloops. Keep holding the power button until it powers off. Then press Volume Down & Power Button to power back up (you might see a slight flicker onscreen that means it should go into Recovery mode). Keep hold of these buttons until you gain Access to Recovery Mode.
This will allow you to Recover or flash a different ROM.
If you're having issues connecting to a computer (Windows) try downloading Windows Media Center for your version of Windows. This will install media drivers to recognize your phone.. If all went well you will get the pop up with A0001 (Codename of OnePlus One). From there you should be able to enter fastboot mode through ADB.
If this doesn't help you, I'm sure that someone else will untangle the puzzle to get your device in good working order buddy. Good Luck.

Nexus 5 D820 Bricked

Hi all,
My Nexus 5was running stock Android M till last week and I wanted Android N. So I rooted my phone installed TWRp and loaded android N by @santhosh. Everything went well but at times some apps kept crashing including TWRP. So I decided to to do a clean wipe. I did a clean wipe from recovery but after that my phone is not booting up. It's stuck on bootloop.
I am not able to boot into recovery mode also is there any way to save my phone?
Pardon my English.
Are you able to access the bootloader (hold power button + vol down until the phone boots)
I suggest using NRT to flash a stock ROM.

No i can't. It will go to bootloader When I press volume down + power but only for a second or so.. After that it'll bootloop.

Sounds like a dead power button?
Not sure, never had this problem.
But that is a common issue
The fact that the phone is not detected by the phone makes it difficult to re-flash a stock ROM.
If it is a power button issue, I recommend removing the motherboard, cleaning around the power button with pure isopropyl alcohol., quickly press and release the power button using a bit more pressure that usual, replace the motherboard, and try again.

connect to computer while doing and it works
You can boot into recovery without having to plug into a computer by holding power + volume up, and then once you get to the "this device is unlocked, press power key to continue" screen, rather than just waiting for that screen to disappear, press the power key and then you should be taken to recovery... at least, that's how I was able to do it

Ah gotcha, that makes sense, I've never been able to get recovery booting via power + volume up, until I randomly tried pressing the power button at the device unlocked screen, and for some reason doing that took me into recovery

What is the unlocked screen? Never saw this
Are you powering off your phone first? If so wait a few seconds after then hold down both power + volume up buttons at the same time and hold for 10 seconds. It still works for me doing it this way.

This works like a charm. I was about to give up my phone because of this predicament, I didn't want to have any issues restoring my phone in the future in case. THANKS A BUNCH!
It's kinda strange but it is bootloader issue. I am on BTK3 firmware (latest Android 10 release) and i'm experiencing such misbehave of key-kombo to enter ot recovery mode since September or October FW update. Has jus tried to downgrade bootloader to initial firmaware (ATGM) by flashing BL in odin and now i can enter recovery by only pressing vol-up + bixby. It work always. Cables, headphones... nothing needed. just keys-combo.
Then i tried to update BL to latest Android 10 (BTK3) and again recovery mode doesn't work. Only if N9860 connected to PC by cable and even with that it doesn't work for me 10 out of 10 times.
Can someone text/call Samsung support to report this issue ?
BTW thanks to @Mentalmuso for helping me!
Same things happen to Android 11.
Tried to flash on my N9860 old BL over Android 11 firmware (was installed before that, all files AP, BL, CP, CSC), flash was ok, but system was unable to load. constantly bootloops. but i was able again to enter recovery without cable and etc. Tried to wipe cache and factory reset from default recovery but no luck - bootloop.
I thought that game over and old BL is not compatible with new android 11.
But then i wanted to try do the same but with custom binaries (@Mentalmuso TWRP and kernel) and ta-da - system loaded from the first try. For me it's surprise. Now i have Android 11 latest FW for TGY (CUA3) with initial BL from the box (ATGM) and everything looks like working fine. No error in OS, no random reboots (at least after 30 minutes of test) and recovery can be simply loaded only by key combo, without any cables, headphones and PC.
I'm happy now =)
Strange thing is that after fladhing old BL system did not show error message that vbmeta changed and some error in vbmeta header. It was showed always on Android 10. But i flashed twrp again (it has vbmeta inside .zip) to be safe lol.

Samsung Galaxy a40 stuck on "powered by android" screen

Hello, I have a Samsung Galaxy A40 and yesterday I tried to flash LineageOS (I already have experience flashing gsi's), but when i rebooted the system, it just stuck on the "Powered by Android" screen.
It's not even rebooting, it just stays on that screen until the battery dies. So I've tried to let the battery drain and then booting into download mode after charging it a bit by pressing Vol Up + Vol Down and then plugging it into pc, but for some reason it just won't boot into download mode. What can I do now without having to risk booting into that screen and having to wait another full day again?
Hi,
You probably have to flash the latest firmware for your device.
If the phone freeze on the powered by android screen you can press and hold volume down + power and the phone will force reboot.
To reach download mode you can try this :
Turn off the device
Press and hold Volume UP key + Power Key for a while
Release all key when Samsung logo appears then you will see Android System Recovery
Select Reboot to Bootloader
Use Power key to Confirm

I'd prefer not to boot it up now bc it's turned off, if i have to I'll try. But, is there a way to boot it into download mode when it's already turned off?

The easiest step is the keys but look like it doesnt work for you.
You should try to boot with different key combination get past the bootscreen, otherwise i suggest you to got to a repair center if you can't
