[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.

Instructions

1. Install custom recovery - use my twrp

2. Download the zip - firmware

3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei

4. Full wipe all

5. Flash firmware

Information

My port based on:

firmware: A600NKSU1ZSB6 (Korea version SM-A600N) Android 9.0 with February security patch

kernel: T585XXU4CRJ8 (our stock 8.1 kernel) 3.18.14

As you known - in friday (1 March 2019) was opened beta testing for A6'18 in Korea. It has the same exynos 7870.

[MENTION=8351239]gyogubin[/MENTION] public twrp backup with 9.0 stock firmware (all beta versions send as ota update, we don't have clean firmware) https://xdaforums.com/galaxy-a6/how-to/south-korea-twrp-backup-copy-a600n-t3906026

1. the same treble logic - vendor as /cache partition and cache as /hidden partition

2. wifi and bt from lineage (I build special 32bit version to get right libs for port)

3. gps, audio config and etc from our stock 8.1

4. small fixes for camera to get it work

Root

This firmware was with magisk. I.e. boot.img already patched.

If you need magisk - you just need install Magisk+Manager_v7.0.0.apk, install, open manager, then reboot firmware and reopen manager

Do not try install Magisk-v18.1.zip - you will get bootloop

Work

Almost everything works, but you have to remember that this is beta version

Problems

1. keyboard - this is port from phone, it use phone layout. I can set ro.build.characteristics=tablet, but it will cause problems with add languages in samsung keyboard app

Hints

1. rotate home screen - open "Home sccreen settings" and activate "Rotate to landscape mode"

2. battery percentage - open "Settings"-"Notifications"-"Status Bar" and activate "Show battery percentage"

3. hide virtual keys - open "Settings"-"Display"-"Navigation bar" and activate "Full screen gestures". And then you can turn off "Gesture hints".
