and my friend will have one soon. How can I give him cfw, or whatever? There's that Despar del whatever, and something else... All I know is that there's some way to do it without fucking with the battery... right? EDIT: I, myself have 3.90 M33. Forgot to mention.
I dont know if you're very sure about what you want/need. I'm 100% ignorant of PSP but I suggest you head over to the PSP subforum and read every sticky that its got to offer...
Erm, gizmo_gal, what forum is this in? The PSP one. There is no way to just give someone CFW. You need to buy/make a Pandora's Battery.
Just buy a Pandora Battery, dealextreme.com has one for 10 bucks: http://www.dealextreme.com/details.dx/sku.12472 Then all you need to do is follow this nice tutorial: http://www.youtube.com/watch?v=BTGmaTYGC2U
This is the easiest method that I have found! Except you still need a battery, I hacked my battery and then used the method above on an XP computer. It worked flawlessly the first time (all of my other attempts, about six, failed to register)!
