Sadly, Sony kept closing these entrances one by one, and there are only so many doors in a house.At a certain moment, there was an unexpected turn – a new way in that worked for all available PSP’s (at that moment).So if you haven’t got one of those, but you’ve got firmware 3.50 or below, use part one.
Some of you might not find this necessary, but some slim PSP’s give trouble without it.
Next, press battery options to produce your Pandora Battery.
Homebrew are applications developed not by Sony, but by the community.
The different types of homebrew applications range from text editors to ISO loaders.
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).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.As I have not tried this myself, I will send you to someone who has.Follow this picture-guided tutorial step by step, and you should be fine, but don’t come crying to us if you mess up.As an alternative, you can also use an automatically generated serial number.
