Hi. When i was installing a9lh on my 3ds back in last summer i accidentally injected my 11.0 emunand on my system without installing a9lh properly. Now the health and safety app is gone. i know that i have fbi installed on it btshould i worry about it? when i downgrade with ctrtransfer to 2.1.0 and install a9lh will the app be on my homemenu again?
