can I solve a failed root?

[Android Central Question]

Hello everybody,

first of all I'm, sorry for my newbie's awkwardness and for my bad english too...

I'm a linux (Debian) enthusiast and I'd liked to install it on my Lenovo Tab M10 Plus; my choice felt on "Linux Deploy" but it needs a rooted device so, after an internet search for tutorials and tips and a system backup (.adb file saved on PC) I bravely tried with Magisk... and I failed (or I think so).

The tablet loops in a never-end booting and on the splash screen appears the message " Orange State Your device has been unlocked and can't be trusted You device will boot in 5 seconds "

I can access in fastboot mode and I tried to flash a no-rooted (downloaded) boot.img but it didn't works (the flashing process reports OKAY but the device reboot anyway in Orange Status), I tried with the flashall command that reports " error: ANDROID_PRODUCT_OUT not set " , I tried to wipe and flash but it didn't works, I granted the access in some recovery mode and tried to install the .adb backup file from the SD card but the system says : " E: signature verification failed E: error: 21 Installation aborted. "
I thought to open the backup .adb file for extract the original files (I don't know if it could be done and if it could be useful)

I think someday someone more skilled than me will solve the problem but, waiting for that day... any advice ?

Thanks, anyway.

Ste

Hi,
thanks for the hint about XDA, I did it.
I've joined the AC community but I think I can't help in something, just try to learn.
Cheers, Ste.
