So as the title says, I'm on an old 3DS XL, I have a9lh on 11.0 with Luma3DS and BootNTR 3.2 installed. I updated Luma3DS from 5.5 to 6.0.1 and now BootNTR says it doesn't recognize the firmware. I reverted back to 5.5 and it's working fine again. I did notice that with BootNTR 3.2 I needed to have the firmware.bin file even though Luma3DS says with 5.0 and up it's not needed. Looking at BootNTR over on github and the newer versions are 3.4 previews 1 and 2 and both say not to install on an old 3DS. So has anyone else got the same issue? Does anyone else have it working?
