OK, brand new 360; havent ever played a game on it yet other than setting up my username prior to the flash.. using a via 2641 card.. - used iprep to get my device IO - used ixtreme 1.1 from xbins - used dos flash "slow" from xbins - used HP disk startup tool kit to make my usb flash drive bootable. hooked up 360, backed up original firmware and everthing was working exactly as it should.. erased original firmware and again ALL signs showed it worked exactly as it should.. then when booting back up into XP, i then opened ixtreme firmware... then copied my original firmare into the "slow" folder and clicked make Ixtreme firmware and it did.. However both the "original" and "hacked" version's icon where one of those that Windows assigns when it doesnt know what application it should open with.. I proceeded with the install after booting into DOS and everything appeared to go GREAT.... When i put in the ORIGINAL game disk that came with my 360 "marvel the ultimate allicance" i get this message "To play this disc, put it in an xbox 360 console"... Ive played with the toolbar on the 360 and it doesnt matter, this message always appears... what did i do wrong here??? what it the "slow" folder i used in iXtreme, or when i clicked "create iXtreme firmware"""??? tellin ya, it seemed to install fine and gave me the correct messages when deleting the original firmware and installing the hacked version.... help..
