Hi everyone, I screwed up big time. I was trying to unlink my NNID so i decided to system format my n3ds. My n3ds has a9lh installed with latest system firmware (11.0) and after i formatted it, now the FBI h&s app don't work. It will just show a black screen when i opened it. I have no idea how to install CIA. Decrypt9 is still working so i tried to do a sysnand restore to sysnand-a9lh backup but it still doesn't work. I think I need to find a way to "repair" my h&S app so i can use it to install HBL and other CIA files. I don't have the original hs.app anymore. What should i do? Update1: I recall reading somewhere that doing a system update can get the h&s.app back to original one so I tried but still no way of accessing the FBI.
