Forgot to back up mso:/eeprom.bin

ok so i was "fixing" my cousin's psp 1.5 fat... the thing is: i thought i did save the "mso:/eeprom.bin" b4 converting it into a pandora, but apparently it did not go through and i dont have the option of "flash only serial from mso:/eeprom.bin"

so how do i fix this problem? and return my cousin's psp batt to normal use aside for the plug ac then battery trick...

You can just use the random code. I dont really think it makes that big of a difference.

hmm i stumbled on a solution... thanks anyway...

What did you do?

I think that the program that i use had an option to turn a soft mod batt to a regular working batt. or something like that. like the title states i can't really remember exactly how i did it..

Why are you pandoraing a Phat w/1.50?
