To upgrade, you will need the custom firmware installer files, and some official sony firmware update files.

Don't forget to use the USB storage safe eject icon in the windows system tray to disconnect your PSP from PC. Don't just pull the cable out.
Steps:
- Format your PSP's memory stick from the PSP menu (all the way left, down to system settings, down to 'format memory stick'. I'm assuming you have a memory stick 256MB or bigger, and not a dodgy (probably fake) one from ebay.
- Download 3.52 M33 (release)
- Download official sony firmware 3.52
- Download official sony firmware 1.50
- Follow the instructions in the readme.en from the 3.25M33 (release) download exactly to install custom firmware 3.52 M33.
You will need to either choose to open it with notepad, or rename the file to readme.en.txt then double click it.- Confirm it has installed ok. All the way left in psp menu, down to System settings, down to system information, check the system software version.
- Download Custom firmware 3.52 M33-4 update
- Copy the 'PSP' and 'seplugins' folders to the root of your memory stick. Root means not inside any folder, so X:\ (where x is the drive letter of the PSP), click 'yes to all' if asked to 'confirm folder replace'.
- Run the 3.52-M33-4 updater from the game/memory stick section of the PSP menu.
Once you're at 3.52M33-4, you can upgrade to one of the more recent M33 custom firmwares from the first link if the game needs a firmware higher than 3.52.
