Please,I need more information on how to upgrade a slim psp to a custom firmware.
Most of the post i came across is about making a Pandora's battery.
1.How do you upgrade to the custom firmware 3.71 m33? Do i need to downgrade the psp slim?
2.I read information and saw videos of upgrading to CFW 3.71 m33 without downgrading using Pandora's battery and memory stick by pressing the X button.
I thought the Pandora's battery was for unbricking as i never saw any information on making it to update a firmware.
3.Are there two types of Pandora battery
(one for unbricking and one for upgrading )or its the same battery that does both.
