3.50 Firmware. What now.

[KingDakai]

Umm I have a Fat PSP with 3.50 firmware in it. I am looking for a solution to downgrade to 1.50 without lumines.

I've heard of Pandora Battery but not quite sure what to do...
Is there any chance I can update to a later version and downgrade from there?

Ultimately I want a custom firmware in it but I do not know how =/

Hello, yes to get cfw you need to get a pandora battery, download rains mms maker: File Details-General-Apps -

You will have to make your own pandora battery, or you can buy a datel tool battery from Codejunkies - Cheat Codes for PS2, X-box & Gamecube

Unless you go for the Lumines hack, Pandora+MMS is the only option for you.

Okay...
So how do I get the Pandora?
Is there other options than using a hacked PSP?
