Ok, I bought a Pandora Battery and Magic Memory Stick. My Fat psp used to be at 3.90. Then I used the Pandora Battery that I bought to install 3.90 M33-3 Custom Firmware on it. Now after I used it, I found out that I have some pros and cons. The good thing about this firmware is that you can play emulators on it with no problem at all. But the bad thing I found out about it is that you cant play any homebrewing games on it or play and PS1 games either. So I was wondering if anyone could help me to downgrade my 3.90 M33-3 psp so that I can use play homebrewing games and PS1 games too? I tried to see if I could downgrade it myself by downloading a program called 3.52 M33 Creator. But when I tried to run it in my GAME folder, it wouldn't start. Does anybody know ANY way for me to downgrade my 3.90 M33-3 psp at all?

Homebrew dosent work cuz you didnt install the 1.50 addon. Install the 1.50 addon and you should be running homebrew again.

PS1 games work on this firmware. Download popsloader and put ur folder with the eboot.pbp file into the GAME folder. Then run the game.

If u need guides for anything I just said, tell me. But, try to use google first

Oh ok I see, Then if thats true then do have to go to the Recovery Menu and make sure that the Kernal is at 1.50 instead of 3.90? If I change that then should that make homebrewing work too?

Also, How do you know if you installed the 1.50 addon? Where would you have to look in your psp to know that you did?

Thank you SO much man! I finally learned how to do it! All I had to do was install the 1.50 homebrew Kernal inside the GAME folder on the psp and Run it and it basically took care of everything and enabled homebrewing for me. Thanx lol!

That is what is suppose to do ... it installs the 1.50 kernel into your PSP ...
