T27P does not boot nor recover

[badmin]

Hi all,

one of our T27P phones just quitted service after a decent amount of time in use.
It won't boot and freezes on the "Welcome... initializing" screen.
I've also tried to recover the phone. Since I haven't found any recoveryfiles specific for the T27P I used the files for the T27G in the first run. After 30 minutes wait I stopped the process and restarted it with the T27 files, but no luck either, it just hangs on the "Start Updating..." screen.
Any ideas how to proceed or should I declare it as retired?

Thanks in advance!
