note if you know how to mount your SD card without taking it out your switch then skip step 1 if you do not know how, do whats on step 1.
1) Turn off nintendo switch by holding power button for 10 seconds. select turn off.
Take Switch-SD-card out and Plug it to your computer. (do not unplug the SD card from your PC until i tell you to do it in a step below)
Download the AllinOnePackage.rar file from :
https://1fichier.com/?8bh9pv9nm7fidmknz6fi
Then unzip the files to your desktop. there will be 2 folders, firmware16.0.0, SD
Drag and Drop the folder "firmware16.0.0" to the root of your SD card. (if you followed my previous guide you will have another firmware folder 15.0.0 go delete it)
2) On you PC open your nintendo-Switch-SD-card (it should be plugged in your computer from step 1)
Delete the files I circled in RED IN the picture below. ( you must delete them completely specially the atmosphere folder if you dont delete it you WILL HAVE Boot issues) (note SEPT folder is NO longer used, since atmosphere 1.0.0 and fusee rewrite ) (you will most likely not have all the files i show on the pic. dont worry you only need the onces circled in red) { if you decide not to delete folders circled in red completely as described you will have boot issues. . . if you want cut and paste onto your desktop}

In the "switch folder" (this is where all your homebrew apps are stored ) I have the latest homebrew apps and thats why you are being asked to replace as you might have an outdated ver. (It is a great idea to download the latest version of your favorite homebrew app compatible with firmware 16.0.0 RIGHT NOW. and place them in your "Swith folder" before proceeding )
Important: inside the allinonepackage double click on the folder called "SD" then open Bootloader folder. you will see a folder called "payloads" drag and drop folder called "payloads" to the desktop ( do it before moving onto step 3 )
3) On you PC: open TegraRCMGUI and click on the little folder with the magnifying glass and browse to the folder called "Payloads" (the one you put on your desktop from step above)
inside you will be able to see the NEW fusee.bin file. select it.
(the old fusee bin you where using will no longer work. you must use the new fusee for 16.0.0 in order to boot. if you use the old one you wont be able to boot. )
then go to step 4
