PSP firmware question

[bimmer01]

Is it possible to downgrade the V2.5 of psp to V1.5?

Any ideas?

I know 2.6 is IMPOSSIBLE ATM, but what about V2.5?

Only firmware v2.0 can be downgraded, so you are out of luck.

You can run homebrew on a 2.5 though, but you need GTA:LCS.

no can't do that. Check the website, PSP Updates for any home brew news.
