Although it seems to be a software issue, a wipe should clean it up a restore to factory.
I have a couple of used BB's and one was doing the same thing and I discovered it was the PC causing the problem. I as doing other things while it was reloading and apparently the PC must have dropped a bit of data and the BB does not have any way to request a resend or validate the software load except to simply fail on boot. You might try a reload with the BB on a pc doing northing else. Make sure the new OS is on the PC
