Elite999 on the QJ.net forums (a great forum by the way) has posted a brilliant guide teaching us exactly how to install custom firmware on any PSP (PSP 1000, 2000 & 300o) no matter what motherboard they have.

This involves using the ChickHEN .tff exploit on PSP with firmware 5.03 so if you have above that version, I’m afraid this will not work.

Without further ado, here is the guide (all credit goes to Elite999)

What do you need:

1 – PSP-1000, 2000, or 3000 (hackable motherboard or non-hackable motherboards).

2 – ChickHEN v2 (13219).

3 – 5.03 Firmware Update (9340).

4 - 5.03 GEN-A for HEN (5436) or CFE 3.60 (762) or CFW 5.03GEN-B for HEN (2247) or 5.03GEN-C (2852).

Note If you have 5.03 firmware installed, then skip this section.

1 – Download 5.03 Firmware Update (9340) .

2 – Create a folder called UPDATE in PSP/GAME on your memory stick.

3 – Extract the archive, and Place the EBOOT.PBP in the UPDATE folder.

4 – Run the 5.03 Firmware update from the game menu in XMB.

5 – When the updater finishes, you will have 5.03 installed. The firmware required to run ChickHEN.

For PSP 2k,3k If you want to boot ChickHEN R2 on these kind of PSPs (2k,3k). I recommend you use this modded version of ChickHen. It is guaranteed to work in the first try. P.S : The same steps apply with this one too.

*If you have a Japanese PSP, then I recommend you change the Character Set in System Configuration to US if you don’t have it set to there yet.

1 – Download ChickHEN v2 (13219) . Open the ChickHEN R2 archive. For slim users(psp-2000,3000): place the folder inside Slim with gif images into your PSP memory stick PICTURE folder (ms0:/PICTURE) (later it will be PICTURE/ChickHEN), for fat users(psp-1000): place the folder inside FAT with gif images into your PSP memory stick location PICTURE folder.

2 – Now place the h.bin into the root of your memory stick pro duo. Where the folders PSP, MUSIC etc are located.

3 – Go back into settings in your psp and turn off UMD Auto-Start and UMD Cache.

4 – Place the memory stick into the PSP, and navigate to your photos folder, and enter the ChickHen folder. Wait, you will see five egg giff images, these will start to load thumbnails. Your PSP may freeze and reset. Just keep retrying and ChickHEN R2 will load up….But if you see flashing colors, your PSP will reboot loading the ChickHen.

Remark! You don’t have to be on 5.03 GEN-A/B to update to 5.03 GEN-C.

1 – Download 5.03GEN-C (2852) for ChickHen R2.

2 – Extract the ZIP, and drag the “GEN-C” folder to PSP/GAME folder on memory stick.

3 – Run the updater VIA XMB->Game Menu.

4 – When the process finishes, press X. The PSP will reboot.

1 – Download CFW 5.03GEN-B for HEN (2247) for ChickHen R2.

2 – Extract the ZIP, and drag the “5.03GEN-B” folder to PSP/GAME folder on memory stick.

3 – Run the updater VIA XMB->Game Menu.

4 – When the process finishes, press X. The PSP will reboot.

1 – Download custom firmware 5.03GEN-A for ChickHen R2 from the download link supplied above.

2 – Connect your PSP to the computer in USB Mode.

3 – Extact the 5.03GEN-A_for_HEN.zip archive for example to your desktop.

4 – Double-click on LAUNCH-ME.exe (GUI) which can be found inside the folder extracted.

Note Now if the program didn’t launch and showed an error, then continue reading this step, if not then continue to the following step. Download .Netframework 2.0, which is the minimal version that can run “LAUNCH-ME.exe”. When the download finishes, install .NET framework.Then launch “LAUNCH-ME.exe (GUI)”. If it still displays an error, just PM me.

5 – Choose options PSP-2000 or PSP-3000 (depends of your PSP). Mode : Choose option FULL. Set driver of your psp for example: G, H, F, etc… It depends on the usb port that the psp is connected to. Click start, the files are being copied to your psp.

6 – Disconnect the PSP from USB. Navigate to the game menu, enter your memorystick, then launch the main EBOOT.PBP.

7 – When the application loads, press L or R to flash the firmware in your flash. YOU ONLY NEED MAKE IT ONE TIME!

8 – Last but not least, press () to reboot in the custom firmware.

How to slightly alter the risk of losing CFW (GEN-A/B) :

What does the plugin do?

• Patch the Reboot of the PSP.
• Patch the Shutdown of the PSP.
• Hide UMD Update Icon.
• Patch flash 0, 1, 2, 3 for USB access.
• Redirecting the file version.txt to ms0:/PSP/SYSTEM/version.txt.
• Patch the blit TIFF image “blit corrupted data for file with extension .tiff”.

1 – Download Sedna for CFW 5.03 GEN-A/B (476).

2 – Extract it, and Copy the folder seplugins in the root of your Memory Stick.

3 – copy this line ms0:/seplugins/Sedna.prx 1 in the file X:/seplugins/vsh.txt, X:/seplugins/game.txt. When that is done, the CFW becomes permanent.

Note X : Is the letter of the PSP device (ms0, memory stick).

Some notes about Sedna:

• If you reboot your PSP via power switch, your PSP will be back to 5.03 OFW.
• You can reboot the PSP via reboot device option in the vsh menu and you’d still be on 5.03 GEN-A/B.
• Shutdown option in VSH places the PSP in Standby.
• This plugin prevents access of any flash files (Flash0 or 1 or 2 or 3) to prevent permanent brick accidents.
• It makes the version.txt which shall be in flash0/vsh/etc/ in ms0:/PSP/SYSTEM/ so that you can still use version.txt, although you can’t access Flash0 files.
• It hides the UMD update icon , to prevent you from updating to OFW higher than 5.03. Updating your 5.03 firmware will lead to the destruction of chances to place custom firmware on your PSP.

Note If you are on 5.03 GEN-A, and want to install CFE 3.60 or vice versa, check the section after this one.

1 – CFE 3.60 (762) A.K.A 3.60 MHU A.K.A 5.00 M33-6 for unhackable PSPs VIA Pandora.

2 – Extract the archive and prepare the folder “CFWEnabler” to be copied (it is located in PSP/GAME after the archive is extracted).

3 – Connect your PSP to the computer, and copy CFWEnabler folder to PSP/GAME.

4 – Run the updater from game menu in XMB.

5 – Click on the first option and accept.

Note After the first time you install CFE, don’t install it again. If your PSP crashes or shutsdown due to any reason, just launch the updater and don’t press anything. It will automatically reboot your PSP to CFE.

Uninstalling GEN-A then installing CFE or vice versa:

Note You need version older than 3.60 to uninstall CFE or GEN-A. GEN-A installer doesn’t have an option to uninstall CFW files in flash0, so we will use CFE 3.30 here.

1 – Download CFE 3.30 (0).

2 – Extract the archive and prepare the folder “CFWEnabler” to be copied (it is located in PSP/GAME after the archive is extracted).

3 – Connect your PSP to the computer, copy CFWEnabler folder to PSP/GAME, and run it from XMB.

4 – Press the option to uninstall CFW files (GEN-A files or CFE files), it will uninstall both if they are present.

5 – When you finish, choose if you want to update to CFE 3.60 or GEN-A. After you finish, follow the 5.03 GEN-A section if you want to install GEN firmware, or follow the CFE 3.60 section if you install it.

Remarks! These kinds of CFW are not permanent (unless you have GEN-A/B Sedna patched). If you shutdown the psp, the psp will not load the custom firmware again. You need to reload ChickHen R2, then launch EBOOT.PBP of GEN-A and press o when you enter the menu. Because of that, I recommend just using the standby mode. When you have installed the custom firmware in your flash, you can remove the “files” folder in the MS ROOT.For your own safety, it is better to rename or erase the prx called “flasher.prx” in the MAIN APP folder to avoid wrong flashing times. Don’t ever flash an irrelevant firmware to your psp-2000,3000 (flash0) (unhackable motherboards). This will result in a permanent brick that can’t be fixed until a new exploit is found.
