Hiya all. I’m new to these forums and was really hoping for some help. I have previously downgraded my friends PSP slim 2000 and updated his firmware to 3.80 m33 a long time ago since then has been using it fine until he upgraded to Sony’s 5.51 official firmware now he cannot access some of his other content on the memory stick. I have still got my Pandora battery and a 512 MB memory stick can someone point me in the direction if I can downgrade his firmware again or is it not possible with 5.51 to downgrade a PSP. If anyone has any Noob Guides/Youtube guides I would really appreciate any help you guys have to offer,
I have my orginal fat psp with custom firmware still its running 5.00 m33-6
Many Thanks I hope someone can help.
Liam
