Someone else's Nand backup will not work on your system.
They're console unique.

You can use this Guide to recover your Switch

Can he even follow the guide when he doesn't have access to a NAND backup, and most likely not even his Boot0/1 files ^^

Yeah during Step 2.2:

Step 2: Backing up your NAND
By backing up your NAND (the Switch’s internal memory), you will later be able to restore it in the event that anything goes wrong, essentially rewinding it back to a previous state.

If anything goes wrong during this guide, you can always restore this backup with Hekate and restart

1. Enter RCM and send the “hekate-ctcaer-4.9.1.bin”* payload while holding Vol- to skip autoboot and enter the menu
   
   
2. In Hekate, select ‘Tools > Backup > Backup eMMC BOOT0/1’
   
   • Use Volume +/- to change menu selection and Power to select an option

PS: Donwnload Firmware 5.1.0 from your trusted Source! (Not 6.1.0 and above)

I thought I bricked my switch yesterday, could not get it to connect to my laptop.
However read a few posts and holding the power button down for about 10/15secs reset it, then tried again to inject a payload and it connected!

Hi boot into OFW 6.0?. You might want to check fuel burn then start backing up your nand on 6.0 with all the keys. Otherwise if you scare to turn off your console then officecial update to 8.1 then use atm with new sig patch, with is not really recom IMO. Good luck.

Ps. Please use canna tut for proper backup your nand.
