[G4 Q&A, Help & Troubleshooting] kingbling:
2 days ago my g4 started to reboot without any further explaination. I tried to factory reset, wiping. Jump on another ROM. Currently running Cyanogenmod 13.

It didnt change. Sometimes i just freezes from waking up. Sometimes it reboots itself. Can be 5 minutes or 30 seconds.

I tried adb logcat and filtered fatal

$ adb logcat *:F
- waiting for device -
--------- beginning of main
--------- beginning of system
--------- beginning of crash
