So, I got a bit hack-happy and decided "Hey, it would be a cool idea to fool around with the Home menu in the KD folder!"
A minute later, I'm faced with an oddly-bricked PSP.
This one is not the usual semi-brick you'll get from editing RCO files. This one has disabled my Recovery menu, and crashes when I launch games. So, there goes my two recovery plans, PSP-Filer and Recovery mode.
But wait! There's one last thing left: SCEP plugin!
I'm currently trying to get SCEP to move files to flash0, but it seems it's unable. I've already deleted the corrupted impose.rsc file, so I'm not sure if I'll be able to get to this state in my PSP again without a modchip.
My question is: How do I move files to the flash0, or rename files in the flash0, with SCEP?
I can't express this with enough emphasis: I need an answer QUICKLY. Because as I said before, I deleted the file, and it may not let me get to this place I am again if I turn it off and turn it on later once I get an answer.
