[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
This ROM is discontinued. The successor of CyanogenMod is LineageOS which can be found in the corresponding Thread. The Downloads will be left here for the time being.

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 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.

What works:

- Display

- Sound

- WiFi

- 4G Data

- Bluetooth

- NFC (somewhat flakey)

- LED

- Magnetic Cover Sleep/Wake

- Double-Tap to wake

What doesn't work:

- FM Radio (It works, but only if Bluetooth is off and breaks if BT is on while Radio gets enabled)

- Camera (Taking Pictures works, but sometimes the camera is not able to connect. Taking a video crashes the mediaserver.)

- LiveDisplay is not working correctly

- Performance Profiles cannot be set (CM14.1 issue)

- 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 Recovery (This only applies if you do not have one already. If you do, go to the Flashing section below):

If you flash for the first time, you first need to download the CM recovery for your device from below.

To flash it, you need to put your tablet into fastboot mode (VolUp + plugging in USB-Cable) and then flash the recovery like this:

fastboot flash FOTAKernel recovery-scorpion.img

If you come from stock or from a ROM that does not support Recovery on the FOTAKernel partition, you also need to fastboot flash the boot image for your device before rebooting into recovery.

fastboot flash boot boot-scorpion.img

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 cm-14.1-(DATE)-UNOFFICIAL-scorpion(_windy).zip

gapps:

CM14.1 was tested with open gapps for Nougat 7.1 arm (nano confirmed working, others could be problematic)

Tips for better battery life:

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.
