So I finally jumped from kmeaw 3.55 to rebug 4.21 rex.
Never downgraded but still did qa flag.
Upgrade went smoothly. Afterwards was able to sign in to psn and sync all my trophies. Tried some psn and psx games signed for 3.55 - half of them worked while other didn't. I wander if it's because of methods used to fixed them for 3.55 cfw.

The only issue I have and it's a major one. I upgraded to latest multiman 4.10 and whenever I select a game (doesn't matter which game - pre-3.55, 3.55 patched, or with newer firmware), it just goes to black screen and ps3 freezes. It never even gets to xmb where I could launch a game from disc icon (I have original ps3 game in bd drive).
What could be causing this? Do I need to enable/disable certain setting in rebug or multiman to make it work?
If anyone has some idea, please share.

Edit: I got it fixed. I just had to uninstall multiman and do clean install. Must of been two years of updating same multiman installation w/o ever deleting it. Glad to see that all of my 3.55 patched games are working.
