PSP Slim Flash Bang Wallop!

[Macflame]

I have a PSP slim that is not booting (I do not know the history, I bought it that way.).
I can get Pandora to boot and DC5 to install but when I reboot, nothing.
I tried DC4 and 3 same result. I then tried formatting lFlash. Re-install DC5, still the same.
I am now thinking corrupt keys. But can anyone throw some light on this problem?

That's too weird
so you boot, then install, reboot and then nothing

just by any chance, do you have a plugin installed on the memory stick you're using, because that happened to me once, the damn thing wont boot because I had an older cxmb plugin activated and i was starting to freak out.

but I'm thinking corrupted nand too
a little ray of light, change the motherboard, but I don't know how much it costs

i'm with mike .. when I hacked my psp slim the first thing they had me do was a nand dump .. so if anything happened I'd have a copy of the original nand. I don't have any idea what you'd do with out it.
