I tried to update my firmware from 4.2 to 5.3 but I keep getting an error. I am not using a 0800 disk or a bad flash method. What are they for and are they necessary for this situation? What is the problem here? All my IDE channels are disconnected. My 360 was on and my SATA wire was connected. I have tried 14 times and no success. Please help The error: "fail to open input file" I have an ms25 with 4.2 firmware. I have VIA Serial ATA RAID Controller (8237?) I used xtreme boot maker (old and new version, tried both). I also tried the original method but I still got the same exact error.
