Hacking Restoring MSET to original on New3DS?

[Kohmei]

I was previously using the downgraded DS profile exploit on my New3DS to boot into GW mode, which required modification to the sysnand. Now that menuhax exists, I'd like to revert it to the original version, as it causes some issues particularly when trying to use microSD management. How can I go about doing this?

My sysnand is 9.0.0-20U.

You cant get it from NUS so go to the usual place and download a complete 9.0.0-20 pack and find that CIA makes sure to install it with devmenu.
