Switch Informations by serial number - READ THE FIRST POST before asking questions (2024)

Riverpatroll said:

1. I was totally typing in the wrong serial, I included the '4' from the prefix. Thank you for your reply.
2. It's a friend's machine and confirmed serial.

I homebrewed my Switch in late 2021 and I am just revisiting the space for my mate. I'm just not sure if the latest FW has prevented payload injection.

If your switch is unpatched then firmware will never matter, it's unpatched for life.

Sadly, my mine starts with XJW1 and is definitely patched. See here for a link on prefixes guaranteed to be patched:
Prefix List (Alphr.com)

1. Find your device’s “Serial Number” on the underside of your device. It’s the number on the sticker with the bar code.
2. If the sticker isn’t there, you can check it on your Switch by going to “System -> Serial Information.”

Secondhand Switch with orange area XAJ4 serial, seems to be patched

XKK is the same like XKJ and XKW. Same for XJW, XJE or XWW. Everything that doesn't begin with XAJ or XAW is a mariko. Or if it starts with XTJ for example is an aula model (oled switch).

Click to expand...

Is it moddable?

It is. But not via software. Fusée Gelée is patched since mid 2018. You need a modchip for Mariko/aula/patched erista units.

Does this method also apply for Nintendo Switch Lites? And if not is there an alternative way to modify this type of switch. My serial number starts with XJW as well

ALL of Switch Lite are 100% patched.

Remember, Switch Lite came out in September 2019, over one year after fusee-gelee exploit is discovered and Nintendo rushed to patch in new console since mid 2018.

Alternative? mod chip and you have to solder it.
