I used to use paper clips, staples, and screwdrivers as "jigs." But it was getting harder and harder for me to "hit the right spot" and enter RCM mode. Now I use a jig that came with my RCMLoader One. It works great, but when I first bought it I had to use a needle to lift up one of the pins on it.
If your pins are broke, you can replace the joycon rail. They're pretty cheap to buy online, and as long as you have the right screwdrivers it's pretty easy to replace.
This exact same issue happened to me. Make sure you have the latest sigpatches installed. I forgot to put the sigpatches on my SD and it wouldn't connect to my WIFI. Once i put the sigpatches on everything was working fine!
