[12Marshall]

i've been on the full 1/12 version since release and have been loving it.
But yesterday, I shutdown the phone (had no service where i was) and 5 hours later turned the phone back on.
It would not boot into sense 2.5 regardless of what i tried. I did a pimbackup on it and reflashed and the backup was bad and of course lost everything entered or changed since 1/12. However, the phone reflashed fine and is working fine today. I tried several things b4 reflashing including switching to the windows default and back to sense, soft reset etc.
Anyone else experience such a catastrophic failure?
