I got a message on my XT1053 Dev that there's a system update. (I'm running stock) I let it download, and then it wanted to reboot. Ok, but it came up in TWRP. I tried rebooting from TWRP every way, but it would not go into maintenance so it could flash the new firmware.
Now whenever I boot it normally, it comes up, and then immediately shuts down, I guess because it wants to upgrade.
What is wrong with this thing?
There's nothing wrong with this thing....
All of the guides here exist for a reason. One responsibility you have once you have decided to root your device or install custom recovery, is that when a new OTA comes out, you must check back here at XDA to see what the procedure for installing it is.
All of the guides here tell you that you MUST have stock recovery in order to accept any updates.
Here's how you will fix it:
Boot into TWRP. Clear your cache. This will prevent the constant reboots.
Now, use fastboot to flash back the stock recovery. You will need to download the 4.4.2 SBF for your XT1053 from here:
http://sbf.droid-developers.org/phone.php?device=0
Extract the archive. You only need one file: recovery.img
You should already have the android SDK installed since you unlocked your BL and flashed TWRP. Use fastboot to flash the stock recovery:
fastboot flash recovery recovery.img
Now you can accept the OTA from your phone. You may need to go to Settings > About Phone > System Updates and re-download it.
The OTA should now successfully install (assuming you aren't using Xposed or made any other modifications).
Now, you can flash TWRP recovery back. Let us know how it works out for you...
