Hi Guys!

Flashed successfully but there is a problem. I don't see SYSTEM under wipe and can't install any image properly. Is there any fix?

copy-paste the adb output with mouse + enter key, put in [code]tags[/code] here.
while in TWRP
Code:
adb shell
# cat /etc/fstab
# ls -l $(find /dev/block -name by-name)/*
# cat /proc/mounts

Hello, I also have Lenovo Tab M8 8505X and i also want to install twrp in it but i need confirm a few things first
As you said, u have successfully flashed the twrp please answer me a few questions;
Have you also flashed VM.beta and Preserve force encryption in it? or just twrp?
What stock rom was your tablet running before you installed twrp in it?
Also please tell the android version it was runing
and the kernel version too
long story short,
please send the screen shot of the 'About Tablet' section of your tablet.
make sure the screenshot is of full that it also sover the hardware specs because there are so many varients and generation of Lenovo Tab M8.
So i just want to match wether my Tablet is similar to yours before trying to flash.

I flashed twrp first, then the vbmeta via fastboot (not with twrp) and then reboot to recovery by holding power, vol+ and vol-, then releasing power key. That's how I booted successfully into that (TWRP).
And I don't require twrp now, I just reset my tab with smart and rescue assistant. I wanted to flash every treble Android 13 GSI.
My tab is on latest Android 10

But please send your device's About section page's screenshot
so that i can make sure it will work on my device too or not

---

Sure if you want to.
Here you go

---

If it still doesn't help, i would suggest resetting device with LENOVO SMART AND RESCUE ASSISTANT but keep in mind it will delete all your data, so proceed after doing backup.

You need Smart and Rescue Assistant on PC and it can update your tab even with unlocked bootloader. After successful rescue, bootloader will get locked again. Hope it helps
