   1. Navigate to your SDCARD folder on the Desktop.
   2. Inside the atmosphere folder, create a hosts folder if it does not exist.
   3. Navigate inside this hosts folder and copy the two text files: emummc.txt and sysmmc.txt from below.
7. Edit/Create hekate_ipl.ini inside bootloader folder.
   1. If you have an existing hekate_ipl.ini, open it in notepad and remove and lines beginning with kip1= and kip1patch=.
   2. If you want a fresh hekate_ipl.ini, below is a good template to start with.
8. Use Hekate to mount the Switch SD card.
   1. Reboot Switch into Hekate. Press Vol- during the Hekate bootlogo.
   2. Tap Tools on the top bar.
   3. Tap on USB Tools.
   4. Tap on SD Card.
   5. Connect a DATA USB Type A to USB Type C cable from your PC to your Switch.
   6. Navigate to your switch's SD card on your PC.
9. Rename atmosphere to OLD_atmosphere on the Switch SD card.
10. Transfer the Contents of SDCARD to the top level of the Switch SD card.
    1. Say yes to overwrite any files.
    2. Once complete, eject the Switch SD card from within the PC options.
    3. Tap Close to close the window in Hekate.
    4. Remove the USB cable.
    5. Reboot back into CFW.
11. Use either Daybreak to install the Firmware we downloaded in step 5 (for emuNAND or sysNAND users), or the official method in stock (for sysNAND users).
    1. This should always be the last step.
    2. If using the Daybreak method, be sure to keep current settings and install both Fat32+ExFat support.
    3. Once completed, the Switch will reboot.
12. Cross your fingers. Hopefully you will be greeted with the lock screen upon reboot.
    1. Once rebooted, you can download and install individual updated/supported sys-modules, no "packs" and
    2. reinstall themes with updated NX Themes Installer.
