I have a CHECHG01 which is the 256 NAND and I'm running Kmeaw 3.55 CFW with the newest Gaia Manager. Ever since I updated the FW, my MLB 10 The Show has been very choppy and laggy. I did not format the drive or anything and the game ran perfect on 3.41 Hermes v4b. Would the Fix Permissions pkg fix my problem? If not, I transferred the game back to my PC and was thinking of sending it back to the PS3 but maybe the files are somehow damaged and that would be a waste of time?
