[Psp] Downgrading from 4.01 m33-2 without pandora?

[Fulzo]

The other day i made a fatal mistake by upgrading my custom firmware to 4.01 m33-2 now alot of my homebrew doesnt work and worst of all cheat device doesnt work on lcs (GTA: Liberty city stories)

So is there a way to downgrade without pandora battery? (i've got one but ive followed alot of tutorials and i still cant seem to get it to work right :S).
Or is there a way to make cheat device work on lcs on 4.01 m33-2?

Also i should also mention since updating vcs (GTA: Vice city stories) comes up with 'The game could not be started (80020130)' when i try to start it. (Its an iso)

Any help would be appreciated

go to a store buy the game and youll have no problems running it

I had the umd for it i just find it easier having the games as .iso's on my mem stick.
I got my homebrew working again i only had to update the 1.50 kernel.
