Black Screen on First post-flash Boot... sometimes

[Mr. B]

I recently acquired a T-Mobile Touch Pro 2 secondhand from someone who already unlocked it and installed EnergyROM. The seller was kind enough to document what he already did.

I decided to try Silence_012 and the flashing seemed to go fine but when the phone booted I just got a black screen with some dots in a diagonal pattern after briefly seeing the "Black "touch Pro 2" boot screen.

I was able to install both the previous EnergyROM and the stock T-Mobile ROM successfully after this thanks to the bootloader screen.

I then tried MightyROM (latest release) and got a very similar result, except there was some status text at the bottom, pictured at http://mrbsdomain.com/webcam.php.

B 82

I know there are alot of botched flashing threads here but I didn't see any with my particular issues. I know one of you fine folks can tell me what I'm doing wrong.
