Things You'll Need
Instructions
Check the system software version by navigating to "Settings/System Settings/System Information." This process will only work on systems running official firmware 5.03. If the system is lower, update the system firmware to 5.03 (see Resources).
Navigate to "Settings/Retore Default Settings" on the PSP and press "X." Turn off "UMD Auto Start" and "UMD Cache" also located in the "Settings" menu.
Download the latest ChickHEN R2 for firmware 5.03 (see Resources). Extract all files to the computer desktop.
Connect the PSP to the computer via the USB cable. Open the PSP memory card and place the "h.bin" file from the extracted ChickHEN file to the root directory. Open the "SLIM" folder and drag the "ChickHEN" folder to the PSP memory stick "Photo" folder.
Disconnect the PSP from the computer and restart the PSP. Navigate to the "Photo/Memory" menu. When the "Options" menu appears, press "X" to open the "ChickHEN" folder. This should bring up flashing colors and the PSP will reboot into ChickHEN. Navigate to the "Settings/System/System Information." The "System Software" should now be, "5.03 ChickHEN R2."
Download and extract CFWEnabler350.zip files to the computer. Reconnect the PSP to the computer and place the CFWEnabler folder to the "PSP/GAME" folder in the memory card. Disconnect from the computer and restart the PSP. Navigate to the "Game/Memory/CFW Enabler." When the CFW Enabler starts, select "Install." The PSP will reboot after installation and the firmware version should now be 5.00 M33-6. The PSP is now modded and ready to play homebrew and ISO/CSO games.
