Yesterday my device hardware buttons stopped working all of a sudden. I rebooted it using the scheduled reboot feature in the phone settings, because I had no other choice.
It automatically entered Fastboot mode and I can only reboot it by keeping the power button pressed (which now works), but it restarts in fastboot mode again.
I've never installed any custom ROM on this device, nor unlocked the bootloader. I've only used the stock ROM and updated it with official OTA updates from time to time, however yesterday there was no update I'm aware of.
How can I make it boot the normal Android system again?
I've found a partial solution myself: just keeping VOL-UP and POWER buttons pressed for about 10 to 20 seconds reboots it into normal Andoid system, however it still happens it goes into fastboot again when I reboot it normally. I know how to exit fastboot loop, but I don't know why it keeps entering it.

Hi guys,
My Yotaphone 2 is currently stuck in a boot loop (shows android logo, then black screen, repeat) after a software update. I can get to the 'Downloading...' screen via power + vol. key and so have tried adb/fastboot as suggested in other similar threads. ADB can't see the device, which I guess is probably normal since it isn't booted up, but fastboot seemingly can. I've tried flashing the TWRP recovery which seems to go through fine on the PC end but doesn't seem to do anything at all on the phone itself. Calling a fastboot reboot gets the phone back to the boot loop and power + vol. goes back to the 'Downloading...' screen.
I've also tried using the Yotaphone flashing tool to flash a full android image - this also looked like everything was operating OK on the PC end but didn't seem to change anything on the phone once the process was complete.
Is there anything I'm missing or anything else I can try? Any help/ideas much appreciated!
Cheers.

Do you have any idea what caused the bootloop? (maybe installing xposed or something?)
When you keep vol-up pressed at (not after) the moment the phone vibrates during power on, you will end up in TWRP recovery. There you can at least wipe->factory reset. Don't do this if you have stuff on your phone you'd like to keep though. (you can try to rescue/backup those by trying "adb pull <path_to_file>" when the phone is booted into TWRP)

It was caused by doing an OS update (wasn't rooted or modified), I've only since tried installing the TWRP recovery and using fastboot to flash an official image to fix the looping. Flashing TWRP appears to work according to flashboot but holding the volume up key at the vibrate on power on doesn't do anything sadly.

Maybe I should rephrase: the vol-up should already be pressed once the vibrate starts. For a timing-insensitive, fool-proof (no pun intended) way you can enable bootloader (like you did before: you get the Downloading... screen). Then keep vol-up and power pressed together, after 15 seconds the device reboots hard, keep both keys pressed until you see TWRP 'curtain' screen, then release.
Did you try to use the YotaFlasher Windows application to reinstall an official ROM and restore factory defaults? You can get it from here, also download a ROM for your region here.
Hi,
I'm in the process of rooting my G6 (870H) but I've been running in an issue which doesn't seem to happen to other users.
I have followed all the steps (unlocking the bootloader etc), but when I flash the twrp img, reboot (I've tried numerous times both with fastboot reboot and simply by holding the PWR + VOL- ) and then select 2 times Yes when I run into the factory reset screen it shows me the TWRP loading screen (which I guess is normal ) but instead of going into the twrp options afterwards, the phone simply boots as it usually would.
Does anyone know anything about this issue ? I couldn't find any information about it.
I had this happen, make sure after the screen goes black after booting into twrp, leave it alone. So from bootloader Volume + Power then when LG logo pops up stop pressing power but quickly hold it down again. Then when the screen changes don't press anything until booted into twrp.
If this doesn't work, I remember when I first ran into a soft bricked device. It refused to boot into twrp even though I had rooted it. Just keep trying and one time you'll get lucky, I'm not sure why this happens, but it's just part of life, so keep at it and maybe try a different twrp.
Hello all,
Earlier i had ran the battery down to 0% and plugged my phone in to charge. after 10 mins i came back to the phone and I could see the bootloader warning screen;
The Boot loader is unlocked and software integrity cannot be guaranteed..... etc...
No button on the device seems to do anything and device isnt showing under ADB or Fastboot.
Any ideas other than let the device run out of battery?
Rom: OOS
Recovery: TWRP
Kernel: Stock
Root: Magisk
Yeah, that happened to me too, that's why I don't charge the phone turned off
Press the power + vol up buttons till the screen turns off once it does stop pressing them and it should boot up
It's a Magisk bug for what it's worth. Unplug the phone, hold all three buttons and it will vibrate and reboot after a few seconds. Once you see the boot logo, plug it back in and it should finish booting and also be charging.
This happened to me too. I was really worried as I waited over 20 hours for it to drain the battery. All i had to do was to hold volume Up+power button for about 15 seconds.

@mods, perhaps you can merge this thread with https://forum.xda-developers.com/oneplus-6t/help/oneplus-6t-stucked-unlocked-bootloader-t3874178
Guys, do you have any problem using the hw buttons to boot in recovery/bootloader? I tried everytime, but the only way I could boot in there was with the advanced reboot option.
To ROMRACER: Thank you. You helped very much. It works.
not a magisk bug. answered here

I can turn off the phone using the power button and volume up, but after rebooting again, still can't get passed the boot loader warning... any solutions?
I was in this position today.
I'd kept the charger attached whilst going into TWRP to do a NANDROID backup, when I rebooted was stuck at he bootloader warning. None of the suggested solutions above worked for me having tried them several times, each time I got the phone to reboot was again stuck at the warning.
I could get into fastboot, (but from there any method to boot came to the warning again), so connected to the pc and reflashed TWRP image and could then boot into recovery, from there reflashed Magisk and was finally able reboot normally.
Hope this might help someone else.
Hello
I updated the phone to pie when it was released. But after the update i cant lock the phone with power button, Volume up key also not working anymore. Also if i press long press the power button to reboot it gets stuck in fastboot mode. Screen gets blank if i go to recovery. I had to reboot around 10 to 15 times to get back to the system. this is my fathers phone and i dont want to root it yet. Is this a soft brick or hardware related issue. all the buttons work (key combinations work to boot into fastboot and recovery.) volume up and power key becomes unusable only when i reboot back to the system.
Kindly help me what is the procedure flash which stock rom to get the phone back to normal.
Hi,
I'm not very experienced with those root things and followed a tutorial to do so.
I unlocked the bootloader, had TWRP installed and root. This worked. Now I wanted to remove Root and TWRP and go back to the original state. I couldn't find the stock recovery file, so I installed the P996A04V1.3.0B13_MR2_sd_ssl.zip via TWRP from the SD Card. Till here it worked. I could enter the stock recover and boot the phone.
Then Android wanted to install a security update. I allowed it and this is where the problem started.
The install process stood still on 25% for minutes. I thought it stuck and pressed and hold the power button to reboot that I can wipe the memory. But nothing happened. But the installation Process continued suddenly. I had the feeling that this power key worked like a skip key. So maybe it didn't install a file where it was stuck.
After the installation reached 100% the screen switched to black and nothing worked anymore. I couldn't restart the phone or anything but I think the phone was doing something cause it consumed electricity. When I checked the phone hours later I noticed it was empty.
I can reach the unlocked bootloader now, but none of the selections works. Doing nothing to boot or select Recovery lead to black screen and stuck. Then I have to wait until the battery is empty again. Fastboot, Power Off just restart the phone and I end in the Bootmenu again. I can't even fully charge the phone. As soon as it has enough power to start the Bootmenu appears. So I don't see the display of the charging process.
I don't understand how this could happen. I tried different key combinations when the phone had enough electricty to start. The phone always restarts and end in the bootmenu. Only when I press all three keys it's standing still on the ZTE Logo screen but as soon as I release the keys I end again in the bootmenu.
How can I force another Update?
regards
Let' start with the basic questions:
Do you have proper backup of your data?
Which Android Version did your Axon had before it went unusable?
You could try to reflash TWRP.
Boot your phone into bootmode.
Download a proper TWRP Image on your PC (https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547)
Open a cmd shell (press the windows key and type 'cmd' -> press enter)
Navigate to the folder where the TWRP Image is stored ('
Code:
cd C:\Users\[I]YOUR_USER_NAME[/I]\Downloads\
')
Type: '
HTML:
fastboot flash recovery [I]TWRP_IMG_NAME.img[/I]
'
Afterwards you could try to reboot into recovery mode.
I don't have a backup. But there isn't something imortant on the phone that I want to keep. I can do a full reset and reinstall, too.
Android must have been the latest offical availabe what's in the file. Was it Android 8? V1.3.0B13
The fastboot mode doesn't work. The screen turns black and the LED blinks red but only for a moment. Then the phone restarts and I'm in the bootmenu again. Windows doesn't recognize it as device.
Is there a way to force it to do an update from my SDCard without it needed to be connected to a PC?

I don't know of any.
But you could boot into EDL Mode (Press and hold Both Volume button and then press the power button) and flash a Stock EDL rom from the Download Center i have linkd before.
It's not visible for the PC. The only thing I see is the charging screen when its total empty and you can't even boot as. As soon as it has enough power to switch to the normal screen the bootloader appears and when I do nothing the screen turns black and nothing happens. I don't even know if it is charging. The LED is off.
Follow this guide to unbrick it and then use MiFlash and flash an EDL ROM
