My 3DS is on version 9.9. Old 3DS. I have some questions about hacking my 3DS. 1. Is it safe to downgrade? I've seen some people say they have downgraded but CFW doesn't work for them. 2. Do I have to format my 3DS to downgrade or will the downgrading format my 3DS so I lose my eshop games? 3. Will my data from my games be deleted if I downgrade? 4. I read somewhere about 3DS CFW on 10.3. Is it better to wait for CFW on 10.3? 5. Can you show me a link of what to do after downgrade? Like how to install games, Emunand, CFW and such. Thank you for all answers. I hope I do not annoy with my little knowledge of 3DS hacking.
