(adsbygoogle = window.adsbygoogle || []).push({}); I was on 3.55 Kmeaw and i updated straight to 4.21 Rogero and it put me to 4.31, i guess rogero has a built in spoofer, but now i wanna downgrade back to 3.55 Kmeaw. What is there to do??

Use the '999' downgrader. There's a post in Playstation 3 Mods, Cheats and Customizaton section.

Just do it how you would update a CFW, PS3>UPDATE>PS3UPDAT.PUP

Once that's done, get Kmeaw and do the same as last step.

There ya go, oh and I'd recommend using 4.41.2 Rebug Lite if you're looking to go online.
