[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Valera1978:
I'm not responsible for any damage to your device of any sort.

By flashing this you take responsibility of anything that happens.

Process at your own risk!

If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.

As we all know - the tablet does not support treble. And we do not have a separate /vendor partition, i'm using /cache as /vendor.

Instructions

1. flash my twrp from link above - this is latest twrp with system_image support, it need to restore system treble images

2. download system image from https://xdaforums.com/project-treble/trebleenabled-device-development

Known Issues

1. rotate sensor working, but strange - on rotate tablet show black screen for a moment and then back to normal in right state

2. SM-T580 only: gps

Root

Use Magisk, it's should work. If during install Magisk give error about missed /vendor, run my prepare script and the install Magisk: https://drive.google.com/file/d/10JnOtyF5Y_4q1OE3FOZYPDcR7TK1jRhA/view?usp=sharing

GApps - Pie only!!!

Right now on T580\T585 pie images with gapps dnw, it's stuck on the start wizard, what is strange.

Solution: flash image without gapps and then flash gapps. It's working. I'm playing right now with aosp 9.0 and gapps.

We have 32bit recovery and right now standalone gapps think about arm and 6.0.1 version, what is wrong. I took gapps from https://xdaforums.com/android/development/gapps-unofficial-opengapps-builds-t3828141 and fix script inside to arm64 and right sdk version, this is gapps with my fix, what should work on T580\T585: https://drive.google.com/file/d/1kkHUPSznfibcER0DV89GhDdepEjqjCl9/view?usp=sharing

How install gapps:

1. install treble image, then pie system image

2. boot to system

3. restart to twrp and install gapps

4. boot to system, go to play market and login

For now working only this sequence

Recovery

SM-T580:

1. this is original twrp (from https://dl.twrp.me/gtaxlwifi/twrp-3.2.3-0-gtaxlwifi.img.html), I just added system_image support and repack: https://drive.google.com/file/d/10LgZ1rabkgVSyIyd38BxIxNr22_9PJY5/view?usp=sharing

All firmware say about wrong vendor version. This is normal, just press OK.

System images:A only and 64Bits

Checked firmwares

Almost all oreo roms from treble's thread working.

Even new Android 9.0 Pie roms working, but it has issue with sdcard, it will require additional checks from me.
