This will indicate your firmware, as well as your production line and thus your motherboard.
LEGAL DISCLAIMER Using these methods is 100% legal (although Sony obviously doesn’t like it), but it CAN brick your PSP (every model except the PSP-3000 can be unbricked using a working Pandora Battery, though).
For those of you who’ve just tuned in; a custom firmware is one that is written by hackers (or crackers, depending on your point of view), which gives you all the possibilities of the official firmware, but also enables the use of homebrew.
Homebrew are applications developed not by Sony, but by the community.
The different types of homebrew applications range from text editors to ISO loaders.
So if you haven’t got one of those, but you’ve got firmware 3.50 or below, use part one.
All PSPs can be cracked, disregarding current firmware.
You’ll need to use a Pandora battery for all models except those with a TA-88v3 motherboard (some versions of the PSP-2004, the PSP 3000 and up). You can view your PSP model at the bottom of the device.
To check if you’ve got a TA-88v3 motherboard, look for a white sticker on your box and look at the printed letter.
Due to the latter one, which enables piracy, Sony is strongly against homebrew and does its very best to contain it.
There’s a constant battle between the homebrew community and Sony. Last week we posted about various ways to downgrade your firmware.
Today we’ll guide you through a method that works for nearly all PSP’s, disregarding the current firmware.
It even allows you to unbrick PSP’s (people call a PSP bricked when it stops working due to software abnormalities). Simple, the Pandora Battery method requires either the use of a PSP with custom firmware, or a spare battery pack.
