So should I put the file in Nintendo 3DS/id1/id2/dbs (FOLDERS NAMED ID1?) And there make a title.db file, then launch the CFW, go to the Software manager (Should I delete somehing?) and launch FBI to install BigBlueMenu?
I did the backup of the NAND, should I format emunand? (I didn´t install one) or should I put the Launcher.dat of the CFW in the SD instead of the Gateway?
