Hey guys i have been thinking the psp downgrades to 99% then errors out but still works right. I have asked around & got this responce.
the 1% missing is that the upgrade attempts to convert the 1.00 settings to 1.50, and fails since the settings simply aren't 1.00 settings.. which is why they get corrupted and you have to redo them upon reboot.
So if thats the case then in theory if u have a 2.0 then use the downgrader & launch the 2.0 upgrade it should work & get 100%.
any one willing to try?
Only try this if you dont mind ur psp been bricked.
Im jsut trying 2 find out what the 1% of fille thast not been copied is.
