And the guide says this:
If you are currently on an older custom firmware (such a 5.x or 3.x) then you might just be able to run an official update and jump right to the hacking steps, but if the PSP gives an error when you try then you will need to flash-install a clean original firmware before you can upgrade to 6.20 or 6.60. This is done via Hellcat's Recovery Flasher and a copy of the original firmware to flash.
When the process is done you should be on a clean version of 5.00. This will ensure that you can properly upgrade to the latest firmware you want to hack.
- Download Hellcat's Recovery Flasher, and add the RECOVERY folder to your PSP's GAME folder.
- Download the Official Firmware 5.00 firmware file (search google for this), rename EBOOT.PBP to 500.PBP, and stick it in the root of your memory stick.
- Run Hellcat's, and hold L+R+Select while it's loading. When it runs it may warn you if you have GAME plugins enabled, and it will disable them, simply run Hellcat's again.
- When it loads, confirm your choice to enter advanced mode.
- At the second (garbled) warning, Select I AGREE, now take me to the program!
- At the main menu, make sure that Target FW is on 5.00, then go down to /! Install clean ORIGINAL FW (DANGEROUS!!!)
I can't find firmware 5.0 anywhere.
