Love the technical nature of the thread. Thanks especially to BrandonBob and Smacko for testing various methods of finding the problem. Much more usefull than just complaining about it. Here is what (little) I can add. I have 5 Droid Incredibles, in two different towns. One phone has never had a problem. The other 4 all started boot looping at 2am eastern, all on the same day, all about a week after a software update. Now they seem to take turns. My wifes slept thorugh the night, mine "droid"ed me starting at 2am last night. I was wondering, is your phone plugged in at night when this happens? Is this something that randomly happens to phones at 2am only when plugged in? Another thought, since mine will boot loop a couple of times a week, but be fine the other days, any fix, such as formatting your SD card may or may not have solved the problem.
