I'm just asking how do I make my Phat PSP 3.90 M33-3
back to 1.5?

I have some stuff i need to do on 1.5
So how do i do it?
PLease and thank you. =D
Have a nice day.
Recovery folder? I'm not sure if there is one... Just Google it, there's a file there that will D/G your 3.90M33 because I normally use my UPMS to downgrade.

Can i use my PSP Slim Flash files to
replace the flash files in my PSP Phat?

Plus: The problem with my PSP phat is a button malfunction.
Something to do with some key storage or what? Flash corrupt?
I don't know..... i want to reinstall the Firmware.
But my PSP Phat is already 3.90 M33-3......if only it was lower!
And i don't want to use Pandaora!

PSP Slim flash files are different from the PSP's flash files.

Try the 3.71M33 downgrade. It may brick your PSP so be prepared or ask Larry or just Google and Google until you get your answer.
