Configuring 'Custom Firmware'

1. Turn off PSP, and turn it back on holding "R" to access recovery mode.
2. Here you can change some options, below is a list of the common options you might want to change:

Configuration Menu:
Skip SCE Logo (Skips the PSP Bootscreen and disables UMD Autorun, see note below)
Hide Corrupt Icons (Hides 'Corrupted Data Icons' so they don't show on the Game Menu)
Game Folder Homebrew (Changes the folder your homebrew goes into, see note below)
Use No-UMD (Run games without a UMD in the PSP, some games may not work properly)
Fake Region (Use if you have UMD movies from regions that are different to your PSP)
Free UMD Region (Removes the region code on your PSP so it can play all UMD Movies)
Hard Reset on Homebrew (might help with compatibility with some homebrew programs)
Use VSHMenu (Enables or Disables the small menu you get when you press home / select)
XMB USB Device (Change what 'drive' gets accessed when you make a USB connection in the XMB)


Registry Hacks Menu:
Button Assign (You can switch the O and X buttons for Confirm and Exit)
Activate WMA (Activate WMA playback without using wireless internet)
Activate Flash Player (Activate the Flash Player without using wireless internet)


Plugins Menu:
Here will be a list of plugin files you have installed onto your memory stick.

Note about the "Game Folder Homebrew" option:
If this option is set to 1.50 Kernel then you need to put:
Older Firmware (1.00/1.50) homebrew in the "PSP \ GAME" folder.
Newer Firmware (2.xx/3.xx) homebrew in the "PSP \ GAME3xx" folder

If this option is set to 3.xx Kernel then you need to put:
Older Firmware (1.00/1.50) homebrew in the "PSP \ GAME150" folder.
Newer Firmware (2.xx/3.xx) homebrew in the "PSP \ GAME" folder.

Note: Replace '3.xx Kernel' and 'GAME3xx' with the custom firmware version of your PSP. example:
'3.52 Kernel' and 'GAME352' for 'Custom Firmware 3.52 M33'
'3.40 Kernel' and 'GAME340' for Custom Firmware 3.40 OE'

Note about the "Skip SCE Logo" option:
If you only want to disable the UMD autorun, you can do this from the settings menu
in the XMB by going Settings > System Settings > UMD Auto-start: Off

3. Once you have finished with changing the settings in recovery mode, choose "exit" from the main menu.

Reinstall / Uninstall Custom Firmware

Use the custom firmware recovery folder to reinstall the custom firmware.
You can also use these recovery files to go back to an earlier custom firmware:
e.g using the 3.03 OE-C recovery files when you have 3.10 OE-A installed will install 3.03 OE-C on your PSP.

(Note: If you get the blue 'settings corrupted' screen when going back to an
earlier custom firmware version, press the 'O' button to repair the settings.)

-- OR --
You can use the 1.50 Recovery package to uninstall custom firmware and go back to Firmware 1.50.
(Note: If you get the blue 'settings corrupted' screen when going back
to firmware 1.50, just press the 'O' button to repair the settings.)
