You can't flash ROMs on WP8 devices. Microsoft made it so you can't.

I suggest you post this in the right topic.

It is possible btw. Specifically, people with ATT are flashing a pre-portico Rogers Rom and then upgrade to Amber and/or flash with an ATT dev ROM. Lots of people have posted their problems and solutions.
