HOW TO: Recover a Diamond that won't get past the boot screen! (Instructions)

[grevs]

Hi there,

I've had my TELUS diamond for over a year now, and up until recently it has been working flawlessly using the Juicy ROM. Yesterday, the phone abruptly stopped proceeding past the boot screen (the black screen that says diamond and contains several lines of system info in a red font at the bottom).

Fortunately, with the help of this thread, I've been able to get so far as reaching the green background screen that says "tap the screen to set up your Windows mobile based device", and a few times it managed to go to the next screen, "tap to align", but I have not been able to get any further than that. It freezes at the tap screen and does not permit me to activate the screen by tapping, although once or twice it seemingly did, but with an incredible delay.

What I've tried:
-flashing various roms via USB connection, per this thread's instructions
-flashing various roms via Internal Storage, per this thread's instructions
-flashing TELUS shipped rom, per this thread's instructions

I'm really at my whit's end here and sorta freaking out, we all know how important these phones are to us, lol.

Any help or guidance would be enormously appreciated.

Thanks.
