Emunand eshop

Im noob and newbie and i dont know a lot of thing here.

i have emunand rxtools running on 10.3 o3ds and i cant access eshop i got a error saying 022-2634 so looked up on internet they say format emunand and link nnid i did that, now i try to launch eshop and then i get error saying 007-2001

i thinking to upgrade my sysnand to 10.3 and format it and link nnid and downgrade before nintendo sends a patch thats removes arm11 hax on the lastest firmware

Thanks.
