To which "OUT.rgn" file are you referring, the one i made for user LAMedia in Post #25 here? If so, that was for a device with HWID 2826 (dezl fw on board) to attempt a return to full DS50 HWID 2267.

You'll need to refresh my memory of what you've done to this DS50 HWID 2267 device previously regarding flashing/cross-flashing. I can certainly help you with an SD kit but must first know the complete history of the device as well as exactly what you need to achieve.
