I was trying to play a game when I got the error "Error type: card removed the card was removed." I did some research and the recommended solutions were to update Luma and godmode9 to the latest version as well as update the firmware, which I did but the problem still shows up. Then I found out that maybe my SD card was the issue so I ran H2testw, but the program said that no issues were found on my sd card. I then ran chkdsk /f on the sd card, which is when the black squares showed up on my home screen. At this point I think I should probably uninstall the custom firmware and reinstall it, but i'm wondering if what i've done is somehow salvageable. Thanks.
