Give up

[husigma]

I downgraded from 3.5 to 1.5, made the mistake of formatting my memory card now whenever i try to upgrade to anything I get error code 80020001. WTH am I doing wrong?

its best to format your ms after a downgrade, now upgrade to CFW (custom firmware) not OFW..

[husigma]

didn't work same message, i am trying to update to the 3.52 m33. but when i replace psp it has a game150 folder which i dont see on the psp.

[myfavoredcolorisblue]

i think that the folder GAME150 works only for custom fw 1.50 not the official...
try to put cfw 1.50 first (just a suggestion)

[husigma]

ok installed the custom 1.5 but now same thing. what fw should i get?

[myfavoredcolorisblue]

To what fw do you try to upgrade? Try 3.40oe and post again

i wish somebody had shown me this earlier it too late my psp is bricked.

[myfavoredcolorisblue]

it's never too late! use the pandora battery hack to unbrick it! i can't post any urls yet so just google it up!

[myfavoredcolorisblue]

hmmm there seems to be a post on this forum too under the title
"Universal Unbricker for PSP slim&fat" i think it's under custom firmware

[husigma]

yeah but u need a psp with fw 1.5 or cfw to make the battery and all that. mine is fully brick cant start nothing.

this tutorial was just written. It explains how to make a Pandora battery and stick without homebrew.
