Hello, I'm French so I speak very little English but I come here to find answers to my questions. Console : Old 3DS Version : 10.7.0-32E SD card : 16 GB Access to Homebrew : Cubic Ninja (Sky3DS +) I already did a downgrade from my console and it worked. But I came back to the latest version. I wish downgrade yet to find a private header and to install CIA. The trouble is that I have an error code after the downgrade of the CIA files are installed when starting the console. Then when I turn back, the message is still there. I have to L + R + A + Up to regain my console: "An error has occurred. Turn off the console by holding down the power button and try again. i the problem persists, contact the Nintendo Service Centre, you will find information in the manual of the console and the support.nintendo.com site. " What is going on ? Thank you in advance ! And even forgiveness for my bad English.
