Reinstalling Pearl 8100 issues

[Mxyzptlk]

Hi everybody.

I'm trying to upgrade the device software to 4.5.0.37 but I cannot do it. Probably my phone has some hardware problems.

While reinstalling with AppLoader the process is the following:

- Connecting with ROM
- Deleting old files
- Loading JVM and system software
- Initializing device (at this moment a 507 error appears on the phone's screen when booting and I think this is not normal)
- Loading applications (this step is correct)

After the process is finished, the phone never starts and keep rebooting forever.

I have tried to wipe the phone but the problem is still there. I wonder why is this error 507 appearing after loading the system software. Is that normal?

Thanks for your help in advance.
