looping on "unforunately system ui has stopped"

[johnnyminor]

So today I received a XT 1056. I then proceeded to unlock the bootloader and flash SU.

So I then tried flashing a CM 12 nightly build and all went well. I was able to setup the device until the screen was locked and then the phone instantly starts looping through the "Unfortunately, system UI has stopped." error. I've tried flashing an older version of the ROM, and I've tried numerous other 5.0 ROM's but each one will crash as soon as the screen is locked.

And it would not seem like a great idea to revert to an older version of Android and risk bricking the device.

So if someone could advise me how to get rid of the loop error it would be much appreciated.

I have TWRP 2.8.3 currently flashed if that makes any sort of difference....

I tried a fresh install of this CM12 with the gapps it says to use and once again I can setup the phone and as soon I get to the home screen the system UI loop happens. http://forum.xda-developers.com/moto-x/development/rom-unofficial-nightly-lollipop-5-0-t2960768

I also saw your post in that thread to try flashing with these instructions, but it still has the same error.

1 - Download an earlier version of the ROM that booted on you phone along with the gapps.
2 - Flash the ROM and gapps with a suitable recovery... CWM or TWRP 2.6.
3 - Download the latest release that you want to install.
4 - Flash the latest release over the pre - installed ROM without wiping anything.

Is it possible to just flash 4.4.4 or do I risk bricking the device?
