Hey guys i need some help. my psp slim(2001) has 4.01 M33-2 and i want to upgrade to 5.00. Can i just get the 5.00 file and upgrade my psp or do i have to rehack the psp all over again? I haven't used my psp in a long time and kinda forgot what i am supposed to do? help is very much appreciated :biggrin:

Pretty sure, you can just update by drag and dropping the files on to your MS, you will need a 5.00 Eboot renamed to 500.PBP.

Might be worth going up to 5.50 Gen d3 now though, and for that you will need an installer.

Everything you need is here - http://downloads.exophase.com/category/psp/

Use the M33 or GEN installer to update, not directely the Sony Updater EBOOT.
The M33 or GEN installer will read the OFW part out of the 500.PBP or 550.PBP and install the CFW with it.

Good catch, yes the 5.00M33 updater is required. Apologies for that it has been that long...
