I was using the guide on updating arm9loader and after I reach the place were you have to configure the luma boot with no sd card the 3ds would not turn on. I checked and the arm9loader.bin file is on the ctr nand partition, but a9lh doesn't seen to find it. I did download the latest version of a9lh and of safea9lhinstaller and ran it before trying to boot with no sd card, no idea what went wrong.
