Hi guys, I already downgraded dozes of 3ds but I found a error unique. I get a new 3ds xl red in a 9.6U version , tried to update in settings to 11.2 however it gives me a error and restart the console. So I updated to 9.9 using a cartridge of zelda and tried again to update in settings but gives me the same error. Finally I installed arm9+luma in 9.9 with soundhax, restored sysnand keeping arm9 and installed fbi, etc. The procedure was fine like any other else. However it keeps avoiding update. - Tried update using settings but give me the same error. - Tried update using Title Manager Bigbluebox with 11.2 cias, but after the end of install when restart console gives me the error: "An error has occurred: Failed to get the CTRNAND FIRM. Press any button to shutdown", so I need backup the nand again to 9.9 - Tried to update in recovery mode, turning on the Nintendo 3DS while holding A+R+L+Up(DPad). By the way I know that updates cias are fine cause I always update using this file, and it is not a dns error ou any problem with the internet because in the same day I updated other two 3ds. Any help would be welcome.
