Get the drive and KV from another console and you're done. Although if MS have detail info about every console white-listed, you'll get banned eventually.
i don't think your method is possible as consoles newer than xenon has KV hashing and cannot be swapped! the method that i used to swap drives was to get a donor fcrt.bin and dummy.bin from DG-16D4S. Dump your nand, RGH the xbox etc and boot xell to get cpu key... replace your fcrt.bin with the donor one and flash that back to the xbox and it should work ok for you know! Then you will have to flash the drive with the dummy.bin flash and then use dosflash to write your correct key to the drive and thats it
hope that helps lol
Just to note i done this mod using a trinity board so i dont no if the crt.bin will be the same as on both model but should be!
