Just sent this e-mail to HTC Support:
<< Hello. Since the recent OTA update to my Verizon HTC Droid Incredible, to v4.08.605.15, I, too, have been experiencing the dreaded 2:00 AM reboot loop, every morning. I've seen various/conflicting responses to this issue, on several Droid forums.
Is there a fix to this, or does letting it "run its course" actually work?
I've tried several suggested solutions, such as removing lately added apps, restoring backed up system settings, pulling the battery, data reset, etc.
When it (finally!) stops, it works, perfectly, until 2:00 am, the next morning.
I've also noticed, that when I pull out the charger/power cord in the early a.m., the screen does not light up, as normal. When I plug it back in, the screen does not light up, either, as though it doesn't recognize the power source has changed.
I just manually set the date/time ahead, to 2:00 am, Sunday, and it's been reboot-looping for the past ~3 hours, straight.
Can HTC please provide a definitive solution? Thanx! >>
Update:
I have received an e-mail acknowledgement from HTC, that they've received my above message.
After the Sat inducing of the 2:00 am Sun reboot loop, I then manually set to 2:00 am Mon, Tue, Wed, and even the following Mon. None of these stirred the reboot sequence.
At about 8:00 pm, last nite, after fully-charging the phone, I unplugged it, and left it alone, overnite. I watched it at 4:00 am, this morning, looking for any sign of the reboot loop. It stayed dark, so I left it that way until 5:30 am (past the ~3 hour window), figuring the battery had either been depleted, or it did not reboot-loop, last nite.
When I pushed the power button, at 5:30 am, the phone turned on, and I was pleasantly surprised to see the battery charge level was at 94% (from 99%, when I turned it off, 8:00 pm Sat nite). Sat's 3-hour reboot loop cycle dropped the battery charge about 25%.
It's been working fine, all day, so far, and I intend to follow the above sequence for the the next few nites, or so, to see if I experience the same outcome.
Cross your fingers...
