Hey guys, I'm new here
So when my PS3 was on version 3.xx, there was minimal freezing and seemingly no serious problems. I continually did every update available, just the average user.
It seems that after the 4.00 update, I have not been able to play many intensive games like Uncharted 3, MAG, Motorstorm: Apocolypse, etc. without it freezing up and, after a forced-reboot, "checking and restoring the filesystem". I understand that this automatic check and restore of the filesystem after any crash can be important in the case that a file was being used and got corrupted... but it is quite annoying.
So, I was wondering if there is a way to restore it back to, say, version 3.73. As for backing up data, I have an external USB HDD that I think I can use. As for restoring to 3.73, is there a file that I can put on a USB flash drive and restore to with no other problems (eg. connecting to PSN)?
