I have FW3.71 m33-2 installed on my PSP. Can I upgrade straight to 4.01 m33 instead of going through all the previous FWs?

Thank you

[unknown333]

Yes, you just need the 4.01 EBOOT. Rename it to 401.PBP (the extension/filetype should already be .PBP) if it's not already.

Just out of curiosity what are the major benefits of this upgrade compared to say 3.95 GEN...

[stallion]

Does this upgrade work on the psp phat as well? and what are the benefits of upgrading to this cfw?

[YamiyoR34]

you can't upgrade directly from 3.95 ofw without the pandora and magic stick can you?

[xniklasx]
