Be aware that improper usage of kernel features can cause serious damage to your device!
Only use the stuff above if you know what you're doing!

In agreement with the GPL, you can find the sources and defconfig used to compile this kernel right here.

Known Issues:
Please keep in mind that CM12.1 sources are still work in progress. As a result, some features may be broken or only partially working.
That's why I decided to only list device-specific issues below.

Below ~60% battery, the displayed battery level will reduce significantly on rebooting. This is a known issue with all AOSP based ROMs.

After switching to a new battery, I noticed this behavior is related to automatic battery calibration and directly affected by the health of your phone's battery.

Disclaimer:
By downloading and installing this ROM, you agree that I cannot be held responsible for any damage caused to your device while installing or using it. Please keep in mind that it's YOU who chose to do these modifications to your device!

Installation:

Make sure your bootloader is unlocked - if not, follow this guide: Link
First installation? Flash the boot.img from ROM zip via Flashtool (use Fastboot mode!)
Boot into TWRP recovery
Do a factory reset and wipe system partition
Flash latest ROM zip (check "Downloads" section)
Flash suitable GApps for CM12.1
Flash latest SuperSU from here: Link
Reboot

Downloads:

Final CM12.1 version: Link (Last updated: Jan 08, 2016)

Guess that's an issue in upstream.. Should be fixed in next build

Thanks neo, this rom with include saber mod, can i use other mod ?

Working good so far, it's got the extra settings/customization that the only other build for TX lacks. No problems so far with bootloops, data restore, etc. except for the issue I think was already mentioned in the T thread, in which TWRP doesn't reboot and hangs if you press the "reboot" button too soon.

:good:

There are enough Xperia apps out there already. Any app that works with CM12 on any phone should work with this specific ROM, too.

Look here.

https://www.google.de/search?btnG=1&pws=0&q=xperia+apps+cm12.1+site:forum.xda-developers.com

Camera button stuff is one of the features that have to be added in upstream sources first.

Hi. Got to hand the phone. I want to upgrade to the current release. Can I rolled forward as an upgrade, or better to install as the installation for the first time? Or enough to make a backup and then to roll back? (exactly what to back up that it include?)

sorry for my bad english.

Check the instructions in third post

You can always do a backup before updating, but I test the builds before upload, so a bootloop or other issues are quite unlikely.
