I tried all of those things with no luck. Screen is not damaged and left it charging overnight. Is it possible that I may have mucked something up with the serial number in the image? I'm guessing the iMX5 checks that section and only boots up if that is correct? See attached image for serial number comparison of the image you sent me David, with the serial number modified on the left hand side and the original backup image I grabbed off the SD card on the right hand side. Maybe I'll try removing the 3 bytes at 0x229.
