I read there are a few things for it so I will have to ask the shop for what is needed. I might try to keep it solderless so I can move it to the 360 if needed.
I thought the CEX2DEX flash was the bad part but its not. That went fine without any problems, it was the firmware installation that YLOD on me. I made sure I did things twice and checked them out to make sure they were correct and all checked out fine but that DEX 355 firmware is the only thing I didn't check and I should've as I thought it wouldn't need checking.
EVERYONE converting from CEX to DEX make sure you double check everything or you will be in the same situation I am in now.
