Do you think they will care what you have installed? Mine was only rooted, but they never questioned it when I got a replacement. I bet they just cleaned it and zapped a new OS. I would not be surprised if it now belongs to a user on this board.......it was in excellent shape, physically.
Maybe PTT has improved, or lost enough users to free-up bandwidth?
We got rid of it a few years ago.......it may have been improved.
I felt too stupid to take on the recovery. Can't help you there.
