[Galaxy Tab 3 8.0 Android Development] gr8nole:
I am creating this thread as a place to discuss development of unofficial LineageOS14.1 builds for the T31x devices. Those of you that have been around here for a while already know that I tend to get busy with other stuff and disappear a times. So, with that said, if you would like to contribute to the development of this rom, please feel free to do so. I can make you a contributor and you will have the ability to modify this OP as required.

LineageOS is a free, community built, aftermarket firmware distribution of Android 7.x (Nougat), which is designed to increase performance and reliability over stock Android for your device.

All the source code for LineageOS is available in the Lineage Github repo. And if you would like to contribute to LineageOS, please visit the Gerrit Code Review.

What Doesn't Work:

- flash it and see

==============================

If you want to use this tablet for phone calls, see THIS post before installing.

==============================

==============================

WIFI WORKS - BUT, If you have an issue with wifi not working AND your mac address shows a value starting with 02:00:00, do not post about it UNLESS you take a dmesg log (immediately after a reboot) and post it with your message. Google can tell you how to take dmesg log or see THIS thread.

==============================

INSTALLATION

- Make sure you're running latest TWRP version

- Copy GApps and rom ZIPs to your internal or external SDCard

- Boot into Recovery

- Perform WIPE:

In TWRP, select Wipe --> Advanced Wipe.

Check Dalvik/ART Cache, System, Cache, and Data

Swipe to Wipe

- Flash rom zip

- Flash GApps zip

- Reboot

Updating to a newer version of THIS rom ("dirty" flash)

- Boot into Recovery

- Flash rom zip (no need to re-flash gapps or wipe anything)

- Reboot

If you have any issues after doing a "dirty" flash, do a clean install before reporting any problems.

Google Apps

HEADS UP: Be sure you flash the gapps package when flashing your rom. If you boot your rom, then try to flash gapps later, you will have issues.
