FAQ
Q: Can I install any CIA I want via Ninjhax? / I'm getting an "Invalid signature" error!
A: No. Without something that patches signature checks, such as emuNAND or a CFW, you cannot install CIAs that are not properly signed.
Q: I'm getting a "Database does not exist" / "Invalid database" error!
A: You likely haven't installed anything from eShop or other locations before. You will need to go to the "Nintendo 3DS/<id0>/<id1>/dbs/" directory on your SD card and create empty "title.db" and "import.db" files. Then, go to System Settings -> Data Management -> Nintendo 3DS -> Software on your 3DS and let it repair the database files.
Q: I'm getting a "Could not initialize AM service." error!
A: That error generally means FBI cannot access the AM service. If you are running FBI through Ninjhax 2.0 or Ninjhax through an emuNAND that loads a >9.2 NATIVE_FIRM, FBI will not work.
