I am on Luma. Was planning to update Luma but the Luma Updater wasn't working. I intended to delete the current Luma Updater on my 3ds and install a new one hoping that works. But when I am deleting the LumaUpdater file on BigBlueMenu, I accidentally deleted a title called xdata or is it extdata instead. Now I couldn't access the cias folder. The folder is somehow currupted, 3ds hangs when I go to the cias folder on FBI. Is there anyway to fix this or do I need to restore my 3ds? I followed the 3ds.guide blindly when I was installing Luma so I remembered creating backup file etc. If I have to restore my 3ds, how do i backup my save files?
