How to uninstall a CUSTOM FIRMWIRE from your psp and install a OFFICIAL 1.5 firmwire.

Step 2: ...and now... the procedure,,,

1. Back up all your data on your memory stick as you will be formatting it.

2.Format your memory stick.

3.If you have not downloaded the file from the "what you need step", download it and extract it using win rar.(oh yeah.....install winrar first) =P

4.Connect your psp by going into USB mode.

5.Put the recovery folder into PSP/GAME/

6.Exit USB mode.

7.Completely shut down your psp by holding down the power button or removing the battery (make sure you are NOT going into sleep mode)

8.Press and hold down the right shoulder button while powering on the psp. you will be prompted with a flash screen (recovery mode ,main menu)

9.Select the option that reads Run program at PSP/GAME/RECOVERY/EBOOT.PBP

10.Follow the options as is. "X" to start " "R" to cancel. When done, manually restart the psp by completely shutting down again. Do this by holding down the power button.

11.When powering back on, you will see a blue error screen with lots of words in different languages on it. keep tapping "O" and you will be prompted with the default setup as you did when you first got your psp.

12.That's it your done. I hope this instructable was useful to anyone. Even just one person because then, it was worth writing.

mine did the same thing....now my battery doesnt even work, but it happened right after i put costume fimware on it. it completely fried my battery. all you need to do is start your psp with the charger and no battery in it. once you see the whole menu, you put your battery in.

Well my PSP was semi-bricked b4, at least i could use it. Now thanks to this guide it's completely bricked. Thank's a lot. How can i stick to the "be nice" policy on my first post when my psp is now ruined.

I'd just like to say a massive thankyou to the author of this instructable. I bought a used PSP only to find it has Custom Firmware on it, disabling me from using brand new games because I couldn't update the Firmware with Sony. I searched the net long and hard, like literally a few hours until I came across this. It worked perfectly, and now I can play the new games. Thanks alot to the owner! R.Smith

I'm not sure what the fuss was about... this worked perfectly fine for me! Thanks a lot! Maybe we should mention what kinds of psps these directions are or aren't working on? For instance, mine is a really really old "fat" psp (not the newer slim psps, nor the newest of the "fat" ones); it's model is definitely fro the PSP1001 series, and this worked perfect for me. Maybe people are having problems doing these directions on newer psps? Also, the custom firmware I had on before I did these directions were the 3.52-M33-4 custom firmware and have now downgraded to 1.5 successfully.

This didn't work. Now my PSP is bricked in the worst way (no screen). The console said PANIC several times before writing files. Now I get nothing.
Hey, What do you mean with the right shoulder button is that like the R button? cause I can't get it to work Thanx

You my friend are the man, it worked great thanks alot.
I got a free PSP because my cousin accidentally deleted all the software off it and he gave it to me to see if I could fix it. Well anyway, would this work to reinstall the original software (Or any, I just want to play games) back onto it? If not, do you know how?
