Hey, so I am attempting to downgrade my Sister's Fiance's N3DS from 11.0.0-33U to 9.2 so that I can install A9LH on it, I have successfully downgraded 4 3DSs through this method already but this one has been in use for almost 6 months and has save data and games on it. I was wondering if it would be possible to keep all of his data intact and restore it to his device after I have installed A9LH on it. My working theory at this point would be as follows. 1. Backup the NAND and SD card of my A9LH N3DS, which for these steps will be called 3DS #1 2. Use TinyFormat on 3DS #1 so that my NNID doesn't become unusable 3. Perform a system transfer from his N3DS, which will be called 3DS #2, to 3DS #1 4. Follow Plailect's guide for the DSiWare donwgrade normally using a modded O3DS 5. Wait another week and transfer his data back from 3DS #1 to 3DS #2 6. Restore my NAND backup and SD contents to 3DS #1 Would this setup work to keep both 3DS #1 and 3DS #2 fully functional as they were before modding, or would I be forced to lose the data on one of them? And would the NNID on 3DS #1 be usable after the process?
