j'ai la solution mais en anglais :
This is how you fix 80410aob error
YOUR GONNA NEEDD PANDORA BATTERY TO DO THIS!! IF YOU CANT AFFORD 1 THEN MAKE 1...THERE A LOTS OF VIDEOS ON YOUTUBE THAT SHOWS HOW TO DO IT
1. First you need despertar del cementario v8 from this website
(
http://www.sendspace.com/file/a8qa0o). Drag the v8 folder in your Psp/game folder
2. Download 5.00.pbp ofw at this website (
http://www.sendspace.com/file/yhav4a) and drag it to the root of your memory stick
3. Go to your psp and run the V8 program But make sure that your theme is on Original or classic..not custom.
After installation it should tell you to repeatedly press the button you want to use to launch the despertar cementario v8 program.
i pressed on triangle repeatedly .
4. after that press ok and turn off the psp. hold down on the button you clicked to launch the program..in my case i held on triangle while inserting the pandora's battery.
after that you will see a menu
go to "Nand Operation"
3. Then "id storage"
4.click on "create new id storage"
5.Choose your region and get a mac address. Once thats done then you click (x) to continue
Its going to say something like
"This is only problem for wlan and umd ect.
Then your done. its fixed
This video kind of shows you what the program menu looks like .he starts from step 2 -4 but its not finished
