im flashing an ms28 using iprep and the via 6421 pci card. i prepped my usb drive and booted to it. turned the xbox on, typed in the idump command and got a dump of the fw. i booted to windows to check it, and orig and hacked have matching (unique) keys. i booted back to my usb drive and typed the iflash command. the timing trick worked first time and flashing started, but stopped on the 3rd bank (bank 02) at 97%. now i cant seem to access the drive at all. i have tried using mtkflash e, the iflash command, manually using mtkflash w /m hacked.bin (which i put a copy of in the root of the usb drive). i have tried all timings from 3 seconds up to 15 and it just sits at the line "port : dfa0 master/slave : a0" no matter what i do (mtkflash, iflash etc).
im pretty sure i didnt do anything wrong. the timing trick for read and write both worked the first time, its just that it didnt finish writing. now i cant get the timing trick to work again to erase it/try to write it again.
any advice would be greatly appreciated.
