My o3ds was broken and bricked a year ago,so I haven't touch or read anything about 3ds scenes since then. Then,I bought a new3ds last month and successfully get into b9s luma8.1 now. So,my questions are about LocalFriendSeed : 1)Can i do this dump/inject LFS into luma cfw sysnand,would it cost brick? (it was bricked on my ex-o3ds when i do it on sysnand without cfw) 2)Do i have to do this dump/inject LFS only on emunand? if so,how can i create emunand with gm9? I was ex-gateway3ds user,so i only know how to create emunand in the gateway's way. 3) Does emunand cost some extra space in sd card like gateway emunand and it would deleted everything in sd card? 4)How can i backup b9s luma 8.1 cfw? I just copy everything from my sd card onto pc before doing emunand creation? Thank you in advance.
