My wife has the ls980 and recently installed optimus de on it. Everything was great for over a week until this morning. The phone get very hot and froze. Upon loading back up it will not find any networks and it seems that the efs partition is corrupt as all of the device id numbers read 0. Then after a minute or two it will always lock and restart. I've tried to wipe and reinstall to make it run without restarting to get the pictures off of it, and it didn't help.
My main questions would be is would the efs being corrupt cause restarts, how would I fix the efs, and does flashing a back to stock file wipe the internal storage?
