Hello, First, I apologize for my bad english. I read that downgrade with Sysupdater is not possible on 10.4. I already upgrade my N3DS to 9.5 and this evening, I'll update to 10.4. I ask me if we use again the update function on 10.4 ? For example, when 10.5 and 10.6 will be released, if I want to go in 10.5. (Yes, I know, we get time before 10.5 or 10.6.) Thanks in advance.
