I upgraded my Xiaomi Pocophone F1 “beryllium” to e-0.11-p-2020082870302-dev-beryllium.zip via OTA. After the upgrade the phone started correct. But after the upgrade I don’t have root. Due to my encryption Magisk is not installed. As with every update I wanted to flash Magisk in TWRP. I booted to recovery but I can’t use the keyboard to decrypt my phone.
Did someone had a similar issue? How can I use the keyboard in TWRP. Last time with e-0.10 it worked correct. Now I can’t boot to the system. The phone always boot into recovery.
I tried reinstalling TWRP with fastboot. It doesn’t work. I saw a strange behaviour. The screen shows fastboot. The phone was connected with the computer. When I sent fastboot flash recovery twrp-3.3.0-0-beryllium.img the screen turns off and I had to start the phone to boot into fastboot. Then I got the message target reported max download size of 536870912 bytes sending 'recovery' (31068 KB)... OKAY [ 0.870s] writing 'recovery'... OKAY [ 0.139s] finished. total time: 1.010s
Seemed to work fine.
After that I tried fastboot boot twrp-3.3.0-0-beryllium.img. The same behaviour as before. The screen turns off and I had to start the phone to boot into fastboot. Then I got the message downloading 'boot.img'... OKAY [ 0.808s] booting... OKAY [ 0.088s] finished. total time: 0.896s
I turned off the phone. It automatically restarts and booted to TWRP. But I can’t enter my password. It seems it doesn’t recognize touch input.
OK, or better not OK It seems your kernel is destroyed. You can try downloading MIUI rom for fastboot flashing. Extract it and you will find a flash-all.sh. Remove all lines except of boot.img line and run it. If you will have luck, TWRP will start normally
or you can try flashing a kernel from here https://forum.xda-developers.com/poco-f1/development
@harvey186: Thank you. I will try this. It is strange. I upgraded /e/ from 0.10 to 0.11. After the upgrade the system worked normally. Then I wanted to boot into recovery and the error occurs.
I have access via adb devices -> recovery. Is it possible to restore a nandroid backup with the computer?
Sorry, don’t know, never tried. But you can search the web. Could be that you will find a way.
But if you have a backup, you could flash miui rom via flash-all.sh, install twrp once more and restore your backup.
But first, save backup outside your device
I solved my issue. First I bought an USB-C to USB-A adapter. Then I could use TWRP with a mouse and started a NANDroid backup. After that I flashed /e/ 0.11 with TWRP and thats it. Sounds simple but it took me a week to read so much forum posts with a lot of solutions.
@harvey186: I think I can reproduce the behaviour. When I start my Pocophone F1 to boot into TWRP I have to wait for about 20s until touch will be recognized and I can enter my passphrase.
To reproduce the failure: If I boot into TWRP and unfortunately press POWER + VOL UP twice the screen will be turned off. Then I have to unlock the screen in TWRP and touch input will not be recognized. My TWRP Version is 3.3.0.0.
First aid is to use an USB-C to USB-A adaptor and connect a mouse. With the mouse you can use TWRP and you can reboot.
