Its still not working...I really want to downgrade but I keep getting the "Failed to get CIA file info"
The problem with that error is that there are several potential causes. It may be that you are trying to use the cia files for the wrong type of 3ds [o3ds on n3ds and vice versa], it may be that you are on a Mac and it's inserting system files when you extract/copy the files to the sd card. It may also be that it's failing to get access to the services it needs and that you need to restart and try again.
