If its an MXIC SPI I should be able to extract the key easy enough before updating though? And if I use a sputnik unlock switch would that protect it from locking after updating requiring an unlocked replacement pcb?
Also, do I really need a 360usb or will the CK3 and probe do?
A 9504 drive pre 13146 dashboard can easily be flashed with a ck3 etc, but thats not your problem after dashboard 13146 9504 will become a 0272 and that is where you are going to need a X360USB PRO. The Sputnik switch wont protect the update. There are other ways of using a Via 6421 and a cheap USB to Sata adapter by hot swapping to flash the drive but this doesnt work for everyone. Google/YouTube it for more info.
