Hello, just install rxTools 2.6, and when install .CIA i have in both EMUnand and SYSnand program installed. I understand that is necessary unlink SYS from EMU nand. Recover from forum these info : 1. In sysnand, go to System Settings -> Other Settings -> Format System (Do not accept yet) 2. Eject your Sd card (don't worry, it is safe) 3. Accept to Format your 3DS/2DS 4. After it reboots, go through the setup screen and set everything up 5. Once in the home menu, insert back you sd card and let it create some files on your sd card. 6. Your nands are now unlinked, and there are 2 ID folders in your Nintendo 3DS folder on your SD card (one for emunand, another for sysnand) Now the question : What do I lose and what do I gain ? thank you for any info, m.
