first of all thank you to this site and to hercules for the nice guide which i used to make CFW 3.71 m33-2.ive been here for about 2months learning and understanding the Pandora.and now i manage to have the courage to do so.LOL.

..and it works...my problem is my nand backup..
before i flash my psp with the CFW i made a nand backup and after that i put CFW...the problem is....to my excitement when i got to the xmb i went to system settings and put my nickname and FORMAT my mem stick which contains my NAND backup...huhuhuhuhu
the question is can i make a new one after i put CFW on my unit.???thank guys...
