well i got my ps3 about 2 month ago, jailbreaked and at first i finished all my games without any problems. but i got new games recently and some didn't work, such as heavy rain which goes black every time i start it,and mgs 4 which goes black in first episode when you go to that hotel to meet the rats, but others worked like spiderman and gt.
now when i start them via gaia manager, it just kicks me out in xmb or it goes black. what am i gonna do?
This most likely means that you are running official firmware with a "jailbreak device", update to 3.55 >> Then to Geohot's 3.55 >> Then To Kmeaws 3.55 and it should aleviate all of your problems.
I went from3.41 ofw (official firmware) straight to 3.55 wannikoko version 2 with no probs, installs the load pkg and game etc, use multiman version 1.15.05, and life was sweet no need for dongle.
Put the pup in a folder on your USB - PS3/UPDATE And just do a system update from media storage rather than online, load multiman package from USB make sure not in a folder, all files available through the forum.
