I followed this tutorial and I updated the emunand to 9.8 on my Euro model Old 3DS. https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/ I'm now at the part where you install FBI over the Health & System app using rxtools. The problem is, I boot into emunand and I click Health & Safety but FBI does not boot up. I have all the necessary files on the root of the SD card. Once I open Health & Safety, it opens as normal, the app was not changed at all and then if I go home and check the system version, I am kicked back to the sysnand which I can confirm because the RX around the firmware version is gone. I can still boot back into emunand but I can't get FBI working. I installed everything on emunand, haven't touched sysnand and don't want to.
