Short answer: If your firmware is <=4.1.0 don't update. Otherwise just update!

• You can use ChoiDujourNX on any firmware to update to 5.1.0 or other without burning fuses.
  • Updating is safe as long as you use AutoRCM, which means you will have to boot using a payload over USB from PC or Android Phone (that supports it.)
    • You can downgrade as long as your fuses meet the requirement for that firmware.
      
    • Before you downgrade, always System Initialize/Format or you'll get a bootloop.

• When updating, you update your gamecart slot unless you use nogc (which disables your cart slot altogether.)
  
  • This means you can keep using carts on lower firmware if you feel that is necessary

• You can add the nogc option to some CFWs but research is necessary there; some do not support it or do it differently.
  
  • Currently, RajNX lets you add it to the rajnx_ipl.ini and it also doesn't hang for 10 seconds like on other CFWs.

You can go without AutoRCM but only if you're comfortable booting manually with a jig. And if you boot stock on accident, you burn your fuses and then you can't downgrade.

You can safely update. Homebrew works on 5.1.0. I tested it yesterday.

I have 4.0.1 but I do not understand why not update....

Now I use switch only for backup NAND and probably if I update to 5.1.0 I can do online without ban.

If I do not update and I use some game I can not update online or my switch will ban.

The problem is if some game goes out with a new firmware if I remain in a lower one I will can not run it....

I’m so confused.....

Simple. Update without burning fuses, so you can downgrade when you want.

<= 4.1 is only for a unreleased soft exploit
