I updated my Cyanogenmod nightly to the release for December 8th, 2013. The download seemed to be fine, it rebooted into the twrp, and then it rebooted, but then my phone never loaded back up. I tried restarting my phone with the power button, and eventually resulted to the battery pull, but yet my phone still wouldn't load.
I then tried going into the twrp again, and tried to flash a nightly upload that I had used from December 4th, it seemed to of loaded, but again my phone never loaded up.
I tired all day to use Odin to flash the ATT stock firmware, but I kept getting an ODIN FAILED error. I tried several different firmware downloads for ATT, and again, still no luck.
I am really upset over this, and would love to know why the update didn't work, and MORE IMPORTANTLY, how do I fix my device???
