3.11 downgrade?

I couldn't find any topic on how to downgrade from psp firmware revision 3.11. My psp is currently 3.11 and my friend has an unpatched copy of GTA:LCS. can I use it? Or should O go to 3.50 and use the Lumines downgrade?

id use the lumines downgrader

With your firmware being that high, the GTA downgrader won't work. You need lumines, need to upgrade to 3.50 (NOT .51 or .52) and then follow the 3.50 downgrade tutorial found in the tutorials section.

Lumines downgrader is trusty

Naah, I took care of it. My best friend's little brother had a PSP w/ 3.03. I stealthily swapped ours out. He doesn't even know the signifigance of firmware so . Anyways I got GTA:LCS from my buddy and am now at 3.52 M33.
