Homebrew Can't boot from sysnand after some questionable decicions

[Samukavera]

Hey guys, how are you?

Context:
So, after updating the Hekate and Atmosphere, and updating the sysnand do 18.1.0 firmware, I tryied to use Daybreak to update the emunand to the 18.1.0 firmware.

All good but an error occurred on atmosphere boot (something like this: github /Atmosphere-NX/Atmosphere/issues/1776) and following some loose instructions (and thinking I had a sysnand backup) I deleted the file /save/80000000000000d1 from the SYSTEM partition.

Turns out I only had to delete the atmosphere/contents/010000000000bd00 to solve the issue...

The issue:
Now, when I try to boot from sysnand, it get stuck on the Nintendo Switch screen. And I don't have the sysnand backup to restore the deleted file...

Am I totally screwd or there is a way to fix this? (I would love to keep my 100+ hours BOTW save btw)

Please help!

1) Stop, take a Nand backup before doing ANYTHING else. (Also dump your Boot0/1 and your keys with Lockpick_RCM)
2) Delete Atmosphere folder and Hekate folders (bootloader etc.)
3) Fresh install them, you can use this as a guide - https://rentry.org/UpdateCFWAndFW or https://switch.hacks.guide/extras/updating/

Try again and see if everything is good.

Understood! Doing the backup right away sir!

I'll try the guides and I'll come back later.

Thanks for the help!
