Hi, i follow the tutorial who wrote here: https://github.com/Plailect/Guide/wiki I was on 9.2 official firmware and i downgraded to 2.1. I follow all steps on the tutorial but at the end, while he asked me to boot with Luna3DS i got a black screen with blue light. When i remove my SD card, my 3DS have only the blue light and shut down instantly. I tried this tutorial 9.2.0-ctrtransfer : https://github.com/Plailect/Guide/wiki/9.2.0-ctrtransfer I follow all the steps but i got an error while i backup the file on step 3 and i got this error : Step #3: Injecting CTRNAND transfer image Switching out NAND header first... Auto CTRNAND Transfer: failed! Any help ?
