if you're talking about my "increases your chances of destroying your right joycon rail" statement, IIRC it doesn't brick the Switch.
I think it just makes unable to use the right joycon while slot in. Of course, if you use the wrong pins who knows if you can blow the fuse or short it incorrectly or something. Hence why jig.
Yup, I have performed the hack on two different Switches are two different points in time.
I used the same jig for them both. Only had to use the jig once each effectively. (I have Auto RCM turned on after that)
Frankly the short version is (if your device is compatible):
1) Enter Recovery Mode on your Switch (which would require a jig or some alternate way to enter RCM)
2) Connect USB C cable between Switch and PC
3) Send payload from PC to Switch.
4) Congrats, you're now on CFW.
When you boil it down to that, it's not really that complex. It's just that the guide is very very detailed, so that people don't make any missteps.
So yeah, make sure your device is okay (using the serial ID of your device on the link posted earlier in this thread), is so, follow the guide thoroughly.
Do note it is all at your own risk, of course :3
