[sedkiller]

K So I have a psp that has a problem. First,The first time I got, It woulnd turn on so I created a pandora batterie and tryed to repair it. So after, it was better but somehow worse. It starts and show the coldboot and shows me a blue screen thats sais to press O so I do and it reboots and do the same thing over and over again. I remade a Pandora batterie and putted it and tryed to install 3.71 M33-2 and when ÙIt camme to format flash1 or 0 I don't really rember.. anyway it turns of my psp. So i redo the pandora menu and try to dump my NAND and tells me there is a bad code somewhere in the NAND and turns off. what can I do to restore the psp ???

Did you write anything to flash via USB before this occured? Because it's a known bug and DAX has already made a bugfix for it, but that is for preventing the PSP from bricking. I'm not going to go into detail on how to fix your problem when it's already bricked, because I don't know, but you can read everything about it here and jas0nuk and DAX' posts here.

This bug and bugfix hasn't really been covered by any news sites yet, and someone should do it before more bricks occur.

Update: OK, the name of the site is totally blacklisted and censored here, it seems, so I can't link to it. It's the English forums where DAX posts all his releases, though.

I had a similiar problem, sounds like your system.dreg and system.ireg couldn't be written to. You can fix this by restoring a nand from a 1.5 psp with a regular non cemetary pandora WITHOUT idstorage. Then downgrading to 1.5. Another option would to be manually place a system.dreg and system.ireg in the registry folder of your psp in flash 1 then downgrading to 1.5
