Hey people desperate for some help! Got in a Slim 360 which had a 83850c drive spoofed as a 9504. The owner then went and updated the dash with Dark Souls, which caused that darn error screen. I managed to extract the key off the 83850c drive and got hold of a spare slim 9504 drive. The problem I’m having is that I’m unable to get the ID Strings copied over successfully when I try to paste the key into the target 9504 LT firmware. I managed to get the dash fixed with a MW3 game update using the drive with its zeroed key, this then went and updated the firmware to 0272 and locked the drive. I unlocked the drive but am still unable to get the ID Strings copied over successfully. Please, any ideas or help will be greatly appreciated.
