Project Treble - https://xdaforums.com/c/project-treble.7259/

The Android 8.0 release includes Project Treble, a major re-architect of the Android OS framework designed to make it easier, faster, and less costly for manufacturers to update devices to a new version of Android. Treble is for all new devices launching with Android 8.0 and beyond.

Project Treble results in GSI ROMs.

There are quite a few GSI ROMs available, but not all of them are suitable for T30 tablet.

I started this thread to summarize my experience with using different GSI ROMs.

The prerequisite for installing GSI ROM is an unlocked Bootloader.

Description of GSI ROM versions installation file names:

<ARCH>_xyZ

<ARCH> can either be arm, a64 (arm32_binder64) or arm64

x can either be a or b

y can either be v, o, g or f

Z can be N or S

b = a/b

a = a-only

g = gapps

o = gapps-go

v = vanilla (no gapps included)

f = floss (free & open source apps instead gapps)

N = no superuser

S = superuser included

The most suitable GSI ROM for T30:

T30 requires A/B ROM instalation file type and Android 10.

Suitable are files with key "arm64-bgN" or "arm64-bgS" in filename. "g" if you want use GAPPS.

b = a/b

g = gapps

N = no superuser

S = superuser included

How to install GSI ROMs on Teclast T30:

a) use this HavocOS Installation video guide, but use specific GSI ROM System file

b) use instructions from 2nd post

GSI ROMs are not perfect, they have bugs, and on the T30 tablet I noticed the following two:

- The battery charging animation does not work (charging works OK) when the tablet is switched off

- watching youtube videos in Chrome browser sometimes ends with a system restart (youtube application and embeded internet browser usually works OK)

I have tried all the above GSI ROMs and I was most satisfied with HavocOS and LOSQ.

I continue to use LOSQ, because it has the fewest errors and supports the NTFS filesystem on the inserted SD card.

If you want to try GSI ROM on your Teclast T30, choose LOSQ / HavocOS as the first choice.

I would be happy if here will start a discussion about GSI ROMs suitable for Teslast T30.

in any problems with PC and tablet communication (with platform tools or Flashtool), install the drivers "MTK_USB_All_v1.0.8.zip" or "platform-tools_r30.0.5-windows.zip" from attachment in the 2nd post
