I recently started using an R4I SDHC GOLD PRO 2019 and it was working completely fine until i flashed NTRBoot onto my system. Once i restarted the console, the icon for my flash card no longer appears. I can't get into it at all and the system just says "no game card is inserted". I tried resetting my device to factory settings but this hasn't fixed it at all. Any help would be much appreciated!!
