I have a 3.6v 1800mAh original battery. Firmware 5.02. Almost everywhere I go it tells me that i need to downgrade. I dont know the first thing into downgrading or making my pandora battery or anything. I need help. Please help me. I need step by step help.
First you need a pandora battery to flash the firmware. If you know someone that has a hacked psp you can use their psp to create one. If not you'll have to find one online. I happen to have an extra one that I could sell you (tried selling it on ebay but they always take it down). This is a useful site that will explain how to create and use one:
In the website I linked above you could download emulators to use on the PSP once you have downgraded. They give you instructions on how to use them. You will need a pretty big memory stick to take advantage of this. 1 GB should be enough if you will just be playing nes and snes games, but for PSP or PSone isos the bigger the better.
