Lenovo Tab M8 HD (WiFi‐Only)

📱 Lenovo Tab M8 - TB-8705F

Device Info:

Arch: ARM64
Dynamic Partitioning: A/B (Enabled)
VNDK: not on lite mode
Uses Mediatek MT6762 Helio P22T, exploitable with mtkclient
Has no full stock ROM dump, if you've dumped it and are willing to share, please PM me on discord @bagubaguu. The stock ROM is incomplete so you run risks of hardbricking it until then.
Has an improper super partitioning implementation, thus fastbootD is unavailable. Actions must be done on normal fastboot

Get a stock ROM from the internet or from dumping your device via mtkclient. (Android 14-15 ones don't really work from the tester's experience)
Download a GSI you'd like to install
Unlock your bootloader
Reboot to bootloader either via adb or button combo
If you got it from the internet, Check the build version. If the build version is different than your device, flash the entire rom via fastboot, sspm-verified.img goes to sspm1 and sspm2, etc.
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot flash system <gsi file name here>.img
fastboot -w

If your GSI size is too large, resizing system may help to flash it.

I hate how this device doesnt have a proper fastbootd implementation lol, will be adding more info if needed or gotten a full dump to share
