Hardware 2DS soft-bricked - Help!

[brtatu]

Hey people, I accidentaly downgraded 2ds' mset to 4.0 and formatted it. Now I'm stuck on this screen: http://img15.deviantart.net/2b59/i/2015/167/6/c/23ds_slider_by_maxlempira-d8xlh1i.jpg (not my image but it's the same issue)

I have an emunand backup but I don't know how to proceed. Could someone help me giving a tutorial or some? Thank you!

This is why mset downgrade guides put Warnings for 2ds that if you format this will happen...
