[Galaxy Tab S2 Android Development] retiredtab:
LineageOS 18.1 UNOFFICIAL for 2015 Samsung Galaxy Tab S2 SM-T810 ONLY​

Model: SM-T810 (wifi) - gts210wifi - 9.7" screen, Exynos 5433 SoC, no LTE

This is the ONLY model that the ROM will work on.​

There is NO ROM for the T715 or T815 in this thread. Questions about T715 or T815 will be completely IGNORED.

You MUST READ posts 1-4 (about 10 minute read) before deciding to install this rom. If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.

DISCLAIMER

I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.

All involved in bringing this build to you are working voluntarily on it in very limited spare time, and their other life commitments have much higher priority. Don't expect a prompt, or even any, response to questions and bug reports.

Before attempting to install this ROM

1. Ask yourself: would bricking your device be a disaster for you? If yes, don't try this ROM! It can't be guaranteed stable and reliable enough to depend on for daily use.

2. BACKUP YOUR DATA AND EXISTING ROM. Be prepared for a complete restore if anything goes wrong.

3. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these.

What works

1. bluetooth

2. wifi

3. brightness

4. external audio

5. GPS

6. audio through headphone jack

7. audio over bluetooth

8. selinux enforcing

9. DRM level 3 (SD definition)

10. deep sleep

What doesn't work

1. fingerprint. As I wrote in post 1891 at

https://xdaforums.com/t/rom-unoffic...t810-t815-t815y.3879302/page-95#post-85533725

I will not spend anymore time looking at fingerprint. If you need fingerpint to work, stay with stock Samsung rom.

2. DRM level 1 (no HD definition). There's more detail in post 1891 above. I will not be trying to achieve level 1 for HD definition. If you need HD definition for your $treaming media, stay with stock Samsung rom.

3. If you charge the device while it's powered off and then want to power it on, you MUST wait at least 30 seconds AFTER disconnecting the charger cable before pressing the power button otherwise you might run into strange boot problems such as the touch screen not working.

4. Possibly other features that I haven't tested or do not use.
