I may have bricked my phone (Omnia 7)
After flashing the Samsung ROM it only boots to the Samsung logo and then repeats. I can flash MAGLDR. I cannot flash a ROM in MAGDLR mode. I can only flash the Samsung ROM, which won't boot past the logo
EDIT: It's not bricked. Plugging it into the mains (not a computer) allowed it to finish its ROM install process.
