I just got my PSP and upgraded it to OFW 5.02 before looking at Homebrew... What do I do to put CFW on my PSP. I've already tried but it says it is corrupted data. What do I do?

The exact same problem :(...and I only decided to join the homebrew scene because my psp now all of a sudden wont let me type anything!! So i figured maybe changing it to cfw will make it better again but is there a downgrader for 5.02 ofw?

Yes, there is one downgrader that works for almost all PSP-1000 models and at least a large amount of PSP-2000 models: Pandora's Battery Method.

The last downgrader for a specific firmware version was for 3.50.
 
1.5 and 1

I just got my pandora battery and stick. I have 4.01 firmware on it now I want to downgrade to 1.5 or 1 to emulate on it. anyone help me
 
i previously have a pandora battery for 3.90 but i want to convert it into normal battery
what will i do?

is there any way to downgrade my 5.03slim?

tnx
 
Depends what Mobo is in your slim, use chickHEN r2 on your Slim, determine motherboard and go from there.

For your battery - just replace the serial number using UPT (there are other app's that can do this though)
 
who can downgrade 6.20 ofw plz post it or send i to me as a message 10x

Pandora will work if you have a 1000 or 2000 series PSP model. Otherwise you're out of luck at the moment.
