BlackBerry Flip 8220 Software Errors?

[Sagww]

After recieving Application Error 200, I tried to wipe then roload my phone's OS and apps using the BB Desktop Mgr, but on step 9 0f 11, my BB Flip 8220 froze, displaying the error message: Reload Software: 507. It remained so for more than 2 hrs.

I restarted the process via my BB Desktop Mgr, but once again received the same error message.

I tried to reload the software using the BB Desktop Mgr, but on step 5 of 6, the phone froze again, displaying the following error message: Reload Software: 561.

I think the phone is now inoperable, for it won't respond to my pressing any of its buttons, including the power button.

Any ideas?

Thanks,
