Feedback Switch wont boot up stock firmware after updating

[shado9573]

So basically, i updated my switch to the latest version of 17.0.0. I came back after a while and tried turning it on however it shows the “nintendo” logo and then just shuts down after. I did the hard reset unplugged the adapter and what not but cant boot to stock.
I made a new EmuMMC and for some reason i can access to emuMMC with the version saying 17.0.0 1.6.2 AMS E.
Anyone got advice because idk what to do. I tried backing up and restoring it and that did not work.
I tried doing the nand restore without backup method but memloader displays a trying 1.2.3 infinite loop. However i can access EmuMMC which is weird

So you updated Sysmmc and can't boot that?
You need to boot sysmmc with cfw (atmosphere 1.6.2) once, that should solve it

Aight started working again thaanks. However my wifi was connected to the internet when i launched into emummc and then i turned on airplane. Would that affect or should i perform a restore to my nand again?

That is still not working.

There was a known issue in Atmosphere that caused issues with later firmware. Booting the latest atmosphere should fix it. Don't just copy it to the SD but try to boot it once.
