After successfully flashing a few Hitachi drives, I decided to try and flash my friends ms 28. After a few tries I was able to dump the original firmware. I rebooted the computer and my xbox and attemted to the flash, it failed. I tried several other times and can't even get it to attempt to flash anymore. When I turn off the xbox and select the drive, wait 10-15 seconds, turn back on the xbox and nothing happens. Now its giving me a single red light with error code 1001 when I hook it back up to the motherboard, the center green light is blinking. Im using a compatible chipset with updated drivers and the latest version of iprep. Does anyone know what im doing wrong? Any help would be greatly appreciated.

some get it to work if you wait 5 sec some 10.
6 seconds does the trick for me
samsung ms28 is easiest drive i've flashed.
do to bad flash recovery.
hope this helped
