Note: This pure AOSP vanilla phh treble rom only works on
1)arm 32 ab,
2)arm 32 64bit binder ab
3)arm 64 ab
I have shown tutorial for arm32 64bit binder ab device i.e Galaxy tab A 10.1 but same tutorial will work on your device if that is in the above list (use only vndklite version) and having TWRP installed. Just download appropriate file and follow tutorial but I can’t guarantee it will work for yours or not.
Desclaimer: Do at your own risk.
Download only this file for Galaxy Tab 10.1 A:
Other devices use only ARM64 AB vndklite xz file from below link:
Check your gsi treble version using this app first:
