I got my PSP in the mail today, but I'm having an issue trying to upgrade it to 3.52 M33. It's a v1.5 PSP, but, when I run the KExploitPatcher [suppose to run it on 1.5 PSPs], I get this error message: "this application does not apply to this firmware". Huh? I know I have a white Japanese PSP, but other than that, I don't think there's anything different about it that would affect the firmware. So my question is, is it okay to go ahead and run the M33 firmware creator and stuffs, without having to mess with the patcher? Also, I am not aware if it has been simply upgraded and then downgraded before, the System says v1.5. Thanks for your help!
