[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Disclaimer: Flash at your own risk! Backup your data before flashing! I am not responsible for bricked devices, World War III or your exploding cats!

Warning: The SGP611 images are not tested, but just built by me, as I do not own the device. But as the two devices are the same except for the 4G Modem, it should work. If not, please let me know.

About:

As my beloved SGP621 was just collecting dust, I decided to try porting Android 7.1 AOSP onto it. That worked well, so I moved on to CM 14.1 and now LineageOS

And voila, with a few tweaks here and there, it works (for the most part). But this is still considered BETA, so be warned and flash at your own risk. This will most likely replace the CM14.1 from the thread here, so the Changelog will also be continued on here.

What works:

- Display

- Sound

- WiFi

- 4G Data

- Bluetooth

- Camera (Taking Pictures and Video works, but focus does not work)

- NFC (somewhat flakey)

- LED

- Magnetic Cover Sleep/Wake

- Double-Tap to wake

- LiveDisplay

- SELinux enforced

- FM Radio (only minor glitches remain)

- AptX and AptXHD BT support

What doesn't work:

- Audio Volume has some issues (Loudest in the middle of the slider, than does not change after.)

- QuickCharge (Implementation to high a risk [Overheating], will leave it out for now.)

- You tell me

If your battery depletes rapidly, please disable NFC and check if it betters things. Then comment here, so I can look into it.

Flashing from CM14.1 (This should no longer be needed, as everyone should be updated by now):

If you have CM14.1 from the other thread installed, and want to upgrade, you need to take special care and follow the instructions here or you could end up with a bootlooping device. Anyways, as always, before you try to upgrade, make a backup. I repeat, MAKE A BACKUP! LineageOS is now enforcing SELinux, which leads to all kinds of complications, but makes the device more secure in the end and is well worth the extra effort needed. So lets get to it then.

First you need to have twrp recovery, as cm recovery is, for some reason we have not been able to figure out yet, not capable of installing GApps to the device. After that, flash the update.zip any way you want (via SD or sideload) and DIRECTLY after flash GApps (if you use them. If not you should be good to go). If you forget to flash GApps you will end up in a bootloop. But do not panic, it can be fixed by (you may have guessed) rebooting back into recovery and flashing GApps.

Flashing:

If you installed the recovery to the FOTAKernel partition then, while booting, get your device into recovery mode, by hitting VolUp multiple times once the LED flashes purple. Do so until it turns orange. (If you already have another recovery installed, boot into it.)

Now select install from adb sideload and from your computer issue:

adb sideload lineage-14.1-(DATE)-UNOFFICIAL-Lowtraxx-scorpion(_windy).zip

gapps:

Lineage 14.1 was tested with open gapps for Nougat 7.1 arm (nano confirmed working, others could be problematic)

Tips for better battery life (obsolete):

I installed Naptime to trigger deep doze as soon as the tablet goes to sleep. I also enabled zzmoove cpu gov and noop scheduler in the kernel options. Because of the high display brightness. This leads to me getting standby battery consumption of around 1.2% per hour (measured with GSam Battery Monitor) which is nearly the same amount I got with stock.
