upgrade from 1.50 to cfw after unbrick

hi ive just unbricked my psp and want to go back to 3.40 oe... im on 1.50 the now none of my games work and its annoying.... ive tryed flashing3.40 oe with the flasher progrwm for it it just shuts down the psp when you try it and also i tryed backing up the nand on another 3.40 oe psp and then flashing it via the pandoras battery menu and it says unable to open and restarts the psp, has anyone found away to upgrade yet, or do you thing they will find away to repair the idstorage? thanks for any help:)

umm idk i never had a problem like this. how about try updating to official 2.71 firmware then downgrading from there. then try updating to 3.40 OE again. if that doesnt work then idk..

ok ill try that:)

ehh done all that and still same problem

Did you format your psp battery back to normal?

I doubt thats the problem but its just a suggestion.

try updating to another custom firmware? M33 perhaps.

Yeah but apply the no kxploit patch

didnt he say that eboots wont start?

No he said none of his games work and I'm assuming by games he means UMD's.

he's on 1.5 so most umd's wont work on 1.5
i assumed he meant his homebrew games wouldnt work lol
