IF YOU ARE HAVING TROUBLE (BLACK SCREEN'S, FREEZES, ETC.) DELETE GAME DATA (NOT SAVE DATA) AND RESTORE PERMISSIONS
Okay, i had 3.41 this whole time when random CFW's were coming out left and right because i wanted one that had good backup support and on top of that the lv2 patcher uses PL3 as a base and that was just an added bonus (i hate hermes).
I read around and this one seems to be the best for 3.55. So I updated and im sure glad I did.
All i did was go to official 3.55 and then install Kmeaw's CFW via recovery and bam, it works great.
Just run lv2 patcher before opening multiman (i have the "signed" 3.41 version of 02.15.00 (i think thats the number)) and load your games.
But ill start listing some games i've tested, its not a lot but i havent had a chance to mess with a bunch of games.
Personally tested by me
-GT5 (Untouched, updated to 1.05) and it has worked great with no problems.
-NHL 11(Untouched) i had to delete my game data (not save data) because it was "corrupt" but it also works fine.
Tested by others- i assume these are all untouched aswell
-Assassins creed brotherhood (need to reinstall game data)
-Little Big planet 2
-Call of duty black ops
-need for speed hot pursuit
