so my supposed dead 8320 turned on today for no reason.

i had tried everything from attempting to reinstall the OS and other USB possible problems, but it was dead, not responsive at all, no LED, no screen nothing for 3 months

so when i found it in my desk today with the screen on i reinstalled the latest OS and tested it for a couple hours, it worked perfectly, then after 5 hours its reverted back to being an awesome paperweight.

any ideas on this?

Forgive me if this is something you've already tried and didn't mention, but have you tried replacing the battery?

tried 2 different batteries that are currently working in my current BB

Have you tried "How to wipe with JL CMDR", or "What to do next if JL CMDR won't connect and wipe" over @ blackberryfaq.com?

ive tried to wipe it, but the phone is completely unresponsive, i managed to wipe it with JL CMDR when i was on just to make sure and then i reinstalled the OS

Don't happen to still be under warranty is it?

nope. got a new one from my carrier because this one was dead.

im having the same issue, have you found a fix yet?
