Is there anyway to downgrade or run homebrew on 3.71 PSP fat?

I dont want to make a custom Pandora's Battery because it can be risky and can destroy the battery. Also I think (is there any method to be 100% using the PSP to see if it works or not) the GTA LCS exploit does not work for me.

Anyone?

Well check out this site.

I got the battery and 4gig stick for $26.33 shipped and it works great,I used it on a fat psp and slim psp and all were successful.

Nothing bought/prebought. Looking for software exploits.

Well that's not going to happen.

Nah....you need pandora to make psp exploitable

Well could you point me out to the easiest guide to make a homemade Pandora's battery?

Bumping up...

Anyone?
Or at least a site/forum better than this one for PSP homebrew discussion?

check out qj.net
they have a pretty good psp forum

Right on, check the forum´s you will find what you need

Just get a DATEL Tool Battery from Code Junkies. Despite the name, it is an already made Pandora Battery. And if you're like me and you're a noob in soldering and those kind of things, buying this will save you tons of head aches.

After you get your battery, you'll just need to create a Magic Memory Stick.
