Yeah, remember when I flashed a custom rom to my S7. Before I installed the new rom, I always needed to format the data (factory reset was not enough) because the factory reset only cleared the data partition but kept its format, but the new rom required the data partition to be ext4 or something.
It worth a try to not just factory resetting the phone but do format the data in TWRP. (However, do a backup first as it will wipe your data!!)
