If all got well, download NEW hekate from github
https://github.com/CTCaer/Hekate/releases (if you use it), and Atmosphère also from GitHub
https://github.com/Atmosphere-NX/Atmosphere/releases and extract to the new formated and tested SD Card, try to inject your normal payload (update it if you use hekate or fusee.bin)
if your card is corrupt, you will need a new card.
after you confirm you can start CFW, restore your files from backup and update any sysmodule, theme, etc. you
