i have this r4 sdhc dual-core 2015, and yesterday it was working normally, but i turned my dsi xl off and after this its stuck on a black loading screen, i already tried cleaning the card, reformatted the sd card several times, tried different kernels, tried using another sd card, idk if my ds card reader got damaged or my r4 card stopped working, if anyone know something i can do to fix this i would be grateful.
