no, read the requirements, a Phat psp at 3.52 M33-3 or -4 or a PSP SLIM at 360 M33

Quite new to this

I just bought a psp yesterday (thought I better add that I live in the uk so its a uk one) and it has firmware version 3.71 on it

I imagine that it is the normal 3.71 and not the custom one

I would like to be able to downgrade it and use the custom firmware

Am I still able to just use the 3.71 m33 guide and softwares? in order to do this

Thanks

EDIT: Is a pandoras battery required?

[Bobtentpeg]

Since you are on 3.71, yes pandora is required either to downgrade to 1.5, or just do a straight install of 3.71 M33 using pandora

Thank you for letting me know, looks like Ill have to have a gander on the bay for a pandora battery then

I presume then I can do it using the guide here after getting a pandora battery then?

Please, I have a FAT PSP with the "3.51 M33" firmware installed and I would like to upgrade to the "3.71 M33"

Could you point me to a guide to upgrade my PSP from "3.51 M33" to "3.52 M33-3 or 4" since this is a pre-requisite for the "3.71 M33" upgrade.

Thanks a lot for all your time and attention.
