Hi Guys,

Just dug my PSP out after not using it for quite a while. I have the original Jap PSP with custom firmware 4.01 m33-2.

I'd like to upgrade to the latest custom firmware and would like some advice on which firmware to use and what do I have to do to get it on. Do I just run the installer or do I need to downgrade or anything?

Any advice would be appreciated!

Thanks.
