sorry make sure you patch nand with key and keys OSIGyou need to leave coolrunner in and patch your nand with a dvd key from a dvd drive you have a full dump of
use this dump on the drive you wish yo use with this console
otherwise just knowing the key wont do any good unless its a 9504/0272
and you have the dvd case orig pcb and laser to rebuild your serial info
only if its a 9504/0272 and knowing the serial info can you then remove coolrunner (flashing your stock nand first) build a dummy flash it to a 16d4s whala
