I have downgraded a 2.71 to 1.5 before....this is when I had an extra 1.5 PSP around to get the "DOWNDATER" files require to downgrade the PSP.Now I dont have that PSP around...and my PSP is 3.10OE-A.
I saw that there is a 2.71 generic downgrade..will this downgrade let me update my PSP to 3.10OE-A custom firmware or do I need to find a PSP thats 1.50 to get the files I need??
Or...how easy is to get my 3.10OE-A back to 1.50.....get the files I need and go back to 3.10OE-A and help my friend with his PSP from 2.71>1.50>3.10OE-A............
Any help with this?
