so this is the thing. i was installing some stuff from titledb++, and everything go well, but when i open 3 or 4 suddenly a message apeared in the home screen saying some like "erasing all...", other like "restoring from backup... erasing backup...", and in 5 seconds all but system&dsiware titles was gone. the sd card still full, and i simply can't believe the 3ds can delete 40gb in a moment, so probably is not a big problem to my saves. however, i want to know what happen if possible, and obviusly, all the possible help to get the tickets again. the specs are the typical, a9hl, luma, 11.2. Old3dsXl yes, i saw the error on the thread title, it's a bit hard to me speak in english.
