When the problem occured, I was running this:
http://forum.xda-developers.com/show...00572&page=100 on one of the earlier builds, the 1/9/2014 build.
In an attempt to hopefully fix it, (after doing a backup that nearly burnt out the device), I flashed the 6/3/2014 nightly build, which didn't change anything with the booting.
This problem started happening for seemingly no reason after a freeze. I held the power button until it shut off, and then tried to turn it back on. Instead of the normal boot to cyanogen mod, it takes me directly to CWM. If I leave it on CWM, the device starts getting alarmingly hot and the screen starts flashing rapidly. I haven't seen a way online to get it to boot back into CM. Any help would be appreciated.
