Well, I dont have arm9loaderhax installed. But I have the file arm9loaderhax.bin on my SD, it's fine proceed?
No. If you're not running A9LH, you're using the .dat file. I don't believe the tool even works with the .dat because it can already coexist with other CFWs (if you really can't stand the thought of leaving the .dat file in the root though, well, apparently d0k3 can't either, so you could always use the one from his extended starter pack). I think this confirms the reboot patch is not working correctly on the O3DS (though it's working great on the N3DS). Just downgrade to 5.2 until Aurora can check it out.
