Firmware Installed: 3.73 - 3.71 M33-3

Default 3.73 to 3.71 m33-3

Hello,
ive only discovered this but you can downgrade your psp to get the most out of it. HAHA, im new to all this so i dont really know what i am doing. I have some idea and have picked up some useful information but sadly i need more help.

Ive managed to get the CFW 3.71 M33-3 + Poploader.zip file, but because my psp is on 3.73 i need 3.71 or 3.71 m33. I just can not seem to find this version.

Any links to where i can obtain this wounderful and rare version of psp firmware?

Thanks

I have a FAT PSP by the way

You will need to search for information on Pandora's Battery as you can't just upgrade to CFW from your current firmware.

PB(Pandora's Battery if you couldn't guess) does not require a spare battery.
