How to install GSI ROM - Xiaoxin Pad Pro 2021 [TB-J716F] - Update
My daily driver is now an GSI ROM without any bugs but two small inconveniences.
I tried a few ROMS and the best working for me is LineageOS 20, but only the lineage-20-td build.

Important:
For the GSI ROM to work correctly, it is recommended to update your tablet to the latest ZUI-Version, but you should at least have ZUI14.
Requirements:- PC with ADB and Fastboot Tool + Universal ADB Driver
- Download vbmeta.img (extracted from Stock ROM)
- Download GSI ROM with naming like
arm64-b?N.img
. Personally I use the LineageOS 20 ROMlineage-20.0-xxxxxxxx-UNOFFICIAL-arm64_bgN.img.xz
.
- Go to
Settings
->System
->About Phone
, tab on it until developer settings are enabled. - Go to
Developer Settings
and enableUSB Debugging
, allow USB-Debugging if tablets asks. - Reboot to bootloader:
adb reboot bootloader
- Flash vbmeta.img:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
, you only need to flash it once - Reboot to fastbootd:
fastboot reboot fastboot
- Flash GSI-ROM:
fastboot flash system lineage-20.0-xxxxxxxx-UNOFFICIAL-arm64_bgN.img
and wait - Use the volume keys to select
Enter recovery
- In the recovery mode select
Wipe data/factory reset
and reboot the device.
- Reboot to fastbootd:
adb reboot fastboot
- Flash your latest GSI-ROM:
fastboot flash system lineage-20.0-xxxxxxxx-UNOFFICIAL-arm64_bgN.img
- In menu choose
Reboot system now
Stock Launcher displaying Folders and Names incorrectly:
Solved with latest gsi version
Low Minimum Brightness:Don't turn down your brightness to low, it's impossible to see anything.
Magnet Cover not working:Solved in recent GSI builds based in TrebleDroid, thanks to the contribution from @Ungeskriptet
Battery drainage:In default configuration the GSI ROM doesn't disable display when locked but shows the time with very low brightness. This surprisingly massively drains the battery, just disable it. For this, go to
Settings
->Phh Treble Settings
->Customization features
->System UI Tuner
->Ambiend Display
and turn off Always on
