I've had my PSP for a while now, and i've not been using it because the games are boring, and too costly. I recently found out about homebrew stuff, so I want to downgrade to 1.50, and then upgrade to 4.0 m33, or something like that.
I searched throughout the forum with a solution to downgrading from 3.52, and the only one i could find is the Pandora Battery method. BUT, on almost all of the guides, it says you need a homebrew psp already to run and create the pandora battery.
yes, the only way is to use pandora. There is two other ways. Either buy the DATEL tool battery or make on yourself.
2. Hardmod the battery. Meaning that you have to open that battery up, and pulling out a pin. Note that if you pull the wrong one, your battery would be messed. If you are willing to do this, follow this guide
GUIDE
3. The most safest way, is to buy the DATEL tool battery. It is already a premade pandora battery. If so, follow this guide or use the same guide on the second step.
GUIDE
no. You need to buy the orignal fat battery. There is other names for the DATEL tool battery. To make the magic memory card you can use your pc to do that.
