Uncharted 3 retail disc won't backup to ext hdd
Hey everybody, new to the community but lifetime playstation fan. I borrowed a friends retail disc of uncharted 3 and was trying to back it up to my external hdd and patch so I don't have to update to 3.72 ofw to play it. Can this be done so I can patch the eboot and play without the 3.72? I currently use 3.41 cfw, a phat 80gb backwards comp ps3 with only 35gb left on the internal, and the old jb dongle. I tried Open Manager and multiman on the ps3 but both failed during the transfer, any suggestions, or better to upgrade to 3.55 cfw/2.09 mm?
