Jailbreak Tutorial Using SXOS CFW

Steps:

  1. Set switch to 90dns
  2. Download SX OS, SX Dumper and place at root of microsd
  3. Replace joycon with jig and boot into RCM
  4. Activate license (i did offline initially)
  5. Dump NAND (backup) and save to PC !CRITICAL!
  6. Create emuNAND
  7. Install applications

Ban precautions:

  1. 90DNS
  2. Stealth mode (built into SX OS)
  3. emuNAND

Lets begin! 1. Set switch to 90dns

A precautionary step, you should set your Switches DNS record to point to 90DNS. 90DNS does not forward requests to Nintendos content delivery network (CDN) which will help make sure you do not connect online at the wrong time, by accident. You will not be able to connect to the eShop while connected to 90DNS.

settings -> internet -> manual setup -> input your SSID (network name), password, etc.
– Primary DNS: 163.172.141.219
– Secondary DNS: 45.248.48.62

  1. Download SX OS and place at root of microsd

All of the hacking / homebrew you use will be stored on your microsd. I recommend you format to exFAT.

download the latest sx os
unzip the package and place the boot.dat on the root filesystem: /boot.dat

  1. Boot into RCM

recovery mode is pre-OS, it allows you to load custom firmware, backup your firmware, and other things

power off the Switch.
insert the microSD that now has /boot.dat on it, insert the jig, place the SX dongle (Gear or Pro) into the usb c.
boot into recovery mode (RCM): hold + volume and hold the power button.

  1. Activate license (i did offline initially)

Because the SX Gear doesnt come with a license preloaded, I had to active. If you have a Pro you may not need to do this step.

press “load CFW”
if a popup to activate your licenses appears, follow the directions. I did mine offline (because i did not setup 90DNS first). but you can do yours online

  1. Dump NAND (backup) and save to PC !CRITICAL!

I highly recommend you do this step next. It takes a while to complete and do the data transfer but its worth the wait! besides, you can research while its working

next we’re going to do a backup of our system AS IS, before any changes.

boot into RCM mode
press “other options” -> NAND -> full backup (might say full raw backup or something)
once this finishes, remove your microsd, place into your pc, copy the backup folder to your desktop.

ensure this folder is in a safe place (or multiple places). you can never get this back if you lose it and something happens to your switch!

  1. Create emuNAND

now we will create an emulated version of the NAND you just backed up. the idea is that you will do hacky stuff in the emulated NAND and mostly leave the CFW as is. this also allows you to run multiple firmware versions, but i havent done that yet.

boot into RCM mode (did you remember to put your micro SD back?)
other options -> emuNAND -> create

note: this will erase your whole microsd. if you started with a blank SD, this should be fine for you to do.

  1. Install applications

we’re mostly past the boring stuff! onto the MEAT! we will install the applications that let us actually complete our original goals!

GOAL 1. Play backedup cartridges without them physically present

SX Dumper: performs dumps of Switch games so you can play without the physical cartridges

  • download from SX
  • place the sxdumper.nro file at /switch/sxdumper.nro

How to perform a dump:

  1. boot into CFW
  2. click on the photo album to open the SX menu
  3. scroll right to ‘homebrew tab’ and start sxdumper
  4. insert a cartridge if you havent already
  5. adjust options before starting:

options:
trim: remove unused space from backup (recommended ‘yes’)
splitting: split files. only if using FAT32 format on sdmc (fat32 cannot support files bigger than 4GB)
remove cert: removes unique identifier for YOUR GAME (that specific copy (cartridge or digital download)),
this is ideal if pirating or sharing. keep your cert include if you dont intend to share your backup
since its safer if you want to play online. recommended ‘no’
MORE: keeping the cert and sharing could actually be OKAY… however, if someone else uses the same game
with the same cert and you both play online at the sametime, could result in a ban
