Enable "game patching" in Luma3DS. The mod files are copied to the luma folder. It should work for you now.just can't play the hacked ROM.
It's seem the one did the hack done all things follow the guide and format/ clean up the SD card.
Not sure what to tell you.. If you don't have GodMode9 and the 3ds folder (with the homebrew files) on your sdcard, along with a nand backup (important). Then you should do the Finalizing setup.. No, just leave it as is. Though you should have atleast GodMode9.firm in the : sd:/luma/payloads folder..should I delete the Luma folder which I copied from the hacked ROM and create a new, blank one ?





The sd card is probably failing and giving you these errors..
