I have searched these forums (and the web in general) and have not been able to get the device out of its loop.
I have done the following:
1. powercycle - reboot loop
2. clear the cache and reset to factory settings - reboot loop
3. loaded clockwork recovery and did a cache clear, Dalvik cache clear, and loaded fresh copy of the latest stock ROM from Google (Android 4.3 maguro) - reboot loop
4. via clockwork recovery, wiped the cache partition, wiped Dalvik cache, under mounts and storage - formatted the system, data, and cache partitions, and then installed the latest Cyanogen ROM for maguro as well as the Google APPS and then rebooted. Unfortunately, the reboot loop continues.
In my reading, I came across the possibility that the eMMC may be pooched, although I have no idea how to verify that this is the case.
Can someone please help me with this issue, or is the phone basically toast?
