PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1, 2, 3 and 4 (about 10 minute read). If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.

This is ONLY for the T713. I do not have and will NOT build T719 and T819. See post #2, FAQ 20. Any questions asking to build these will be ignored.

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.

BACKUP YOUR DATA AND OLD rom BEFORE trying my rom.

If you are NOT an expert in using fastboot, adb, odin, heimdall, twrp, DO NOT use this rom. You must know how to use these tools to revert back to your old rom. If you are new to flashing custom roms, do NOT attempt this. If you need your tablet for work and something important, do NOT flash this rom. This rom could result in a bricked device ,boot loop, complete loss of data or non booting device or you not being able to revert back to your old rom.

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. deep sleep

10 DRM level 3 (SD definition)

Known issues/What doesn't work/what's not tested

NOTE: If any following features are important to you, don't use this rom as I will not be fixing them because I

i. don't use/need that feature

ii. already tried fixing it and couldn't succeed and won't spend anymore time on it.

1. Stock camera doesn't work at all (reason i and ii). Starting with LineageOS 19.1 and higher, camera API functionality (pictures and videos) isn't even recognized by the OS. The Samsung camera drivers are proprietary so they can't be changed and there's no open source implementation.

2. fingerprint (reason i). I never use it and I see it doesn't even load correctly in the logs.

3. ARM64 gapps will flash properly (tested with MindTheGapps 13.0.0) but do not receive the permissions needed to function after install. You'll need to go to settings, search for "play store" select the Play store app, then "permissions" and enable notifications. Then back out to the app info page for the Play store, and select "Mobile data & WiFi". And enable "allow network access". Repeat the same for "Google play services". You should now have working gapps and Google play store (try rebooting or clearing app data if not).

4. full disk encryption has been deprecated in Android 13 (LineageOS 20).

5. If you restart the device with the purpose to reboot it and the usb cable is plugged in, the device will not reboot and stay in charging mode. Simply unplug the usb cable, wait 15 seconds and restart the device.

All the source code including the kernel, device trees, manifest and build instructions are provided in post #2 FAQ1.

Thanks

1. LineageOS team for source code.

2. LineageOS-UL team for merging, maintaining the legacy patches needed for old devices into one common reposistory so everyone can benefit.

3. @Deltadroid for updating the msm8976 kernel for branches 14.1 and 16.0 with bug and security fixes. I'm using his 16.0 kernel branch for my 20 builds.

4. @retiredtab for bring LineageOS 20 to the SM-T813, and helping me port this to the SM-T713. And allowing me to use his post as a template for this one. I really couldn't have done this without him.
