Hello, I currently try to downgrade my old 3DS XL in 18.104.22.168E version to 9.2. So i made 2 backup nand in 11.1, they are identical. So i patch my 11.1 NAND backup with 3DS auto firm, and i flash my nand. Result, the console boot properly. I decide to use Ninjahax for entry point. Installation of Ninjahax give me a success message, then when the console try to boot on Ninjahax, that restart a the home menu with error message, i try QR 10.7 or 10.3 maybe a mistake of my part. If i take QR code 22.214.171.124 nothing happen, so i think my dump is correctly patch. Maybe a problem with a file in my sd card ( i try the last smealum starter pack ) , or bad qr code i scan.
