PSP upgrade

markyboy

Hi there,

I downgraded a PSP about a 2 years ago and have been using Devhook.

I want to upgrade to 3.90 M33 and because there have been so many changes over the last year or two, I haven't a clue where to begin.

Any help appreciated.

If you have an original psp battery do the pandora thing might be best way to go(although you should wait onagrite to say what to do that guy must eat,sleep and drink psp firmware!!)

I'm here!!!!!
Anyway what FW is on your PSP now? If you are using Devhook is it the Sony 1.50FW??

Thanks for the quick response!

I've downgraded to 1.50FW and do have an original battery.

The upgrade path is easy but a bit tedious:
Here goes anyway:
Download the Sony 3.52 FW here and Dark Alex M33 here.
Rename the 3.52 EBOOT.PBP to 352.PBP.
Extract the contents of the 3.52 M33 and place the kxploitpatcher,kxploitpatcher% folders to PSP/GAME on your Memory Stick. Copy the 352.PBP to M33CREATOR and also place this folder in PSP/GAME.
Run the kxploitpatcher program first then the 3.52 installer.

Thanks ongarite and witnessmenow.

It also needed the 150PBP and a bit of space on a full disk.

Left a UMD in. When it booted I got an ugly blue screen and thought I'd bricked it.

Battery and UMD out, restart and firmware 3.52 up and running.
Mark.

Its the same process for upgrade for 3.90 M33. Download the DA M33 files and 3.90FW and place the UPDATE folder in PSP/GAME.

Thanks again ongarite. Up to 3.90 m33 now.
