360 backup no go..

Ok since i have a toshiba drive in my 360, my neighbor backs up my 360 games for me and gives me the images ( on a USB thumb Drive 32GB) they pass the stealth check.

He cant figure out why they wont run he told me to try here...
they don't work in his system neither.



Then i tried 3 different tutorials
basically:

Open Image Burn select drive.. change booktype to dvd-rom
choose Tools/Settings and select write tab, then enter "1913760" in the sectors area, select .dvd file then burn.

ive coastered 3 discs ( verbatim +R DL )
