For those of you who don't know me, I have always tried to help with PSPmod and firmware related issues, however, since about 2009 the PSP scene has been dying... So around 2010 I quit the scene... But recently the scene has had a little boost thanks to the Vita's launch!
Feel free to ask me for help, and I will try to answer as quick as possible.
My knowledge isn't great, but can be useful in fixing problems like bricks, launching games, installing add ons, downgrading, upgrading, installing CFW.
So I thought I would start with something basic, installing 6.60 PRO-B
First you will need WinRAR, 7z or another .rar archiving program
PSP 1XXX and 2XXX Users
CIPL_Flaser
FastRecovery
PROUPDATE
All other Models
PROUPDATE
5. You can now run the PROUPDATE game from the XMB under Game and enter CFW, and remain in CFW until the PSP reboots.
6. PSP 1XXX and PSP 2XXX users can now run CIPL_Flasher to make the hack permanent!
I have a PSP go, so I can't FULLY test all these features...
