How to check whether Nintendo Switch is running Custom Firmware (CFW) or Official Firmware (OFW)

Follow these steps to check whether your Nintendo Switch is running Official Firmware (OFW) or Custom Firmware (CFW).

1) On your Nintendo Switch main menu, go to System Settings.

2) Inside System Settings, scroll down until you find System. Tap or press on System to open the sub menu.

3) Inside System, without pressing any button, check the text below the System Update.
If it’s written as “Current Verson: X.X.X|AMS Y.Y.Y” or “Current Verson: X.X.X|AMS Y.Y.Y|E” means you are running CFW (Atmosphere CFW).
X.X.X refers to your Nintendo Switch current OS version
AMS refers to Atmosphere.
Y.Y.Y refers to Atmosphere CFW version you are using.
E refers to EMUNAND – running CFW on MicroSD card. More explanation here: EMUNAND vs SYSNAND – a brief explanation at JILAXZONE.

Most important is that you see the word “AMS” under the System Update. If you don’t see any “AMS” text under System Update, that means your Nintendo Switch is running OFW.

In case you are interested to install CFW on your Nintendo Switch, you can refer to this guide: Beginner’s guide to install Atmosphere CFW on your Nintendo Switch at JILAXZONE.

    Hello, My version is “Current Verson: X.X.X|AMS Y.Y.Y|E” But instead of the E, there is a “S”

    Looks as follows : Current Verson: X.X.X|AMS Y.Y.Y|S

    What does it mean?

    Hello! Ive just got a switch from a friend and its previously been on cfw at some point as even without an SDcard in I can see it has tinfoil on the homescreen but under system it simply says 14.1.1 so I presume its now on OFW.
    Does this mean I can factory reset without any concern? I intend to factory reset, update to 15.0 abd then jailbreak it myself from fresh but for peace of mind I want to wipe anything previously put on there to effectively start from a clean slate and be confident that if anything goes wrong that its something ive done and not them.
    Hopefully this makes sense and thanks in advance for any help. This is coming from someone who used to be heavily into jailbreaking stuff but havent done anything since my iPod touch, Iphone 3 and PSP’s so evidently im well out of practice and confidence as that was so many years ago now.
    Thanks again!
