help with new CFW

ok i got a psp on sony's offical FW 3.8 and i was wondering if i can do the CFW m-33 3.9 by dark alex

Did you install the firmware? Or did you simply save it to your memory?

i installed it...so my psp is FW 3.8

Is your psp Slim or Fat?

fat

Well first off Im going to inform you that you need FW 1.5 or lower in order to place the UFW M33. You must downgrade your psp to version 1.5, in order to do so, you yourself must create a "pandora battery" or find someone with one. Explore the forums using the search function. There are many tutorials to creating a pandora battery. Happy Brewing.
Side Note: I recommend having a spare battery, one for initial psp use. The other to downgrade and furthermore. Im sure at first this may seem overwhelming and complicated, we've all had that feeling. I myself am no good with brewing. If you have any questions a tutorial cannot answer, please message a senior member.
