Flash! Aaaaaarrrrrrggggghh! Green light flashes then nothing.

[Macflame]

I bought a 'bricked' PSP thinking I would be able to fix it. I have un-bricked PSP's before with Pandora. This one has me beat. When you turn on the PSP the green light flashes for an instant then nothing. With Pandora and Jigstick the green power light just continually flashes very quickly.
The PSP will charge up O.K. The Pandora is charged up and I have checked all the motherboard fuses. All O.K. I checked the Pandora and stick on my working PSP. All O.K.
Is it possible that the nand is corrupt? I have read quite a bit on nand flashers but I cannot find anything about the symptoms of a corrupt nand.
The previous owner swears they do not know what happened (yeh right.).
Any pointers warmly accepted. TIA.

If Pandora's or DC's Menu do not appear at all, and you're sure they (Battery and Stick) are working OK, then it is no good news. Probably the IDStorage is severely corrupted.
Again, you should discard any other possible hardware faults.

Looks like recovering (unbricking) that PSP is not going to be that easy :-/

is there a way to unbrick a corrupt IDStorage? I have not seen anything for it.

No that I know of, at least in a simple way like using Pandora.
It must be possible to take PSP apart, locate the flash chip on the motherboard and hook it to a programmer to flash the firmware straight in.... I do not think there's a lot of people with the knowledge and skills to do that.

Thanks for your input guys.
Things are not looking so good for this PSP. I do like a challenge but I feel that this is beyond my current PSP skills. I shall chalk this up to experience and strip it for parts.
But I may just fool around with nand flashers and the like first. I might just learn something and I've nothing to loose.
