What exactly do the Switch modchips do?

[pig_slaughterer69]

To my understanding they inject some sort of electrical signal with nanosecond precise timing which somehow allows unsigned code to be run at a trustzone level. There has to be a more detailed explanation than this. The bootrom bug on Erista Switches had a very detailed technical document published about the buffer overflow and how to exploit it.

I have 2 Switch’s with mod chips installed. The only advantage I noticed is I don’t need a Jig to reboot my Switch after updating or just shutting down my Switch

That's not what they're asking.
