Sorry, I'm not that familiar with the mset exploit so I don't know if I can help you in any way there.When i go in settings and choose profile console freeze without anything new appearing on screen
1. I download and put in root:
arm9loaderhax.bin
Luma3DS.dat
luma\firmware.bin
luma\cetk
2. MSET for NDS cart
3. Then boot mset in nds choose 4.x
4. Go to settings->profile
Is it right?
Because for me it don't work =\
If there is no other user that could help you there, consider updating to 11.2 and doing a full setup of a9lh+luma following the guide http://3ds.guide
and restoring your emunand at the end of the guide if you have one
