i have 2 3ds consoles: new 3ds xl and o3ds. Both are on 11.4.0-37E a9lh. I was using this guide to update https://3ds.guide/updating-to-boot9strap . My new 3ds update went smoothly, however my old 3ds won't launch the start_SafeB9SInstaller.bin. Just to clarify i double checked the naming and it's in luma/payloads. Also autoboot sysnand option is turned off in luma menu. Can anyone help?
