How to update your Custom Firmware in your PSP

Hello, in this blog you will learn how to update your custom firmware in your PSP.

Custom Firmware (also know as “Open Edition) is a special program that can run unsigned code such as homebrew applications and UMD backups.

First, download the Custom M33 Firmware on to this site. http://www.dark-alex.org/

Next, download the Official Firmware on to this site. http://pspslimhacks.com/psp-firmware/official-firmware-updates/

If you’re download the latest CF (Custom M33 Firmware), then your OF (Official Firmware) must have the same version. Example, the latest CF is 5.00 M33-3, then OF must also be 5.00.

Put them in the same folder so that you won’t be confused.

Then, rename the EBOOT.PBP to the version that you want to update. Example, 5.00 is your latest version then rename your EBOOT.PBP to 500.PBP.

Next, Extract the Custom Firmware. After this, connect your PSP into your computer via USB.

Then open it. If the AutoPlay didn’t pop-up. Go to Computer (My Computer in Windows XP), then to your PSP Memory Stick.

After it’s open, Go back to your Custom Firmware then copy the UPDATE folder to /PSP/GAME/.

Then, copy the 500.PBP in to same folder.

Then go to your PSP. Go to Game > Memory Stick > “PSP Update ver X.XX” (X.XX, the firmware version). Then run it.

Follow the instructions (Note. Your battery life must have at least 78% to update your firmware). And there you go! Your PSP is up to date!
