Problems with Dead Space 2 and [Prototype]

Ok i am using kmeaw cfw 3.55. I had jailbroken 3.41 before with [Prototype](BLES00269) working. Now it gives an error about "corrupted game data" even before it gets installed. Tried removing gamedata and different managers and no luck. Same thing on Dead Space 2(BLES01040) the game seems to start and i see the intro but then black screen.

I have copied both games fresh and run lv2-v6 and then fix permissions and still no luck using several managers.

If you have gotten these to work on your console using some tricks or something please explain cus i'm lost.

what the heck is this? if you gonna reply at least be on point

I'm using deadspace 2. I transferred it to HDD through FTP. and running it with MultiMan.

[Prototype] is one i had some issues with setting up on a friends Ps3.. same issue it would say corrupted game data.. what i found was i couldnt put it on the internal HD.. had to come from external not matter what i did.. was the only way to get it going
