So Ive looked through 3 days worth of "Boot loop" Q & A, forum after forum. Nothing answered my problem Ive got a ver 3, never been rooted Evo Ive had since June. Over the last 2 weeks it started randomly rebooting. Last 2-3 days, its turned more frequent and became boot loops, to the point of pulling the battery 5+ reboots. Ive tried - The GPS fix, using MSL # Wiped the cache/Dalvik in the boot menu Restored to factory through the phone & boot menu Pulled SD card, wiped, still boot looped with no SD card I dont use any exchange mailing Ive tried "Always On Data" checked and unchecked Took it to, BB where I got it (with BB insurance), 2+ weeks turn around, and the rep told me if they reload software and it runs for 5-10 minutes they will assume it works and ship it back. The problem lies herein - the phone works for 5-10 under any kind of load, then loops. Games, music, navigation, youtube, anything, 5 min on average and it loops, everytime, completely repeatable. They offered a loaner phone WITHOUT gps/nav ... I need Nav for work Went to a Sprint service center, they were stumped, said for $35 they could have me a brand new one the NEXT DAY. However they suggested to call HTC because they carry the 1 year parts/defect warranty. Anyone dealt with HTC for anything like this? Turnaround time/shipping costs, anything? He said they would replace it for "free", but I cant be without a phone. OR has anyone else solved a similar problem? I can completely wipe everything, load nothing after skipping to set up email, everything, get on the net for 5-10 minutes and it will boot cycle. Please dont merge my post into another thread based on rooting problems and GPS/boot loops. It still persists after GPS reset and/or GPS is off. Thanks! Oh and, phones always been in a case, never dropped/abused, no water contact, nothing particular happened or was changed/installed before this happened.
