U need to make sure the folder in your USB like this: PS3-->SAVEDATA(all files will be in here)
Because mostly when u create the folder in ur USB, eventhough u follow the instruction, it still come out like this: PS3,SAVEDATA,PS3,SAVEDATA (and files in here). It created two times same name folders!
So u have to make sure, it exactly the same the above instruction.
Or if u see it still happen like that, then just create the name " Hello" instead of "PS3". It like this; Hello ---> SAVEDATA. It still work, all files will be there. That what i did and i been through like u too. Have to think,man! Yo Vietnamese,rite???
