Replacing ESCs, am I this dumb?

I'm feeling like a total tool belt AND box, ok, eachine x220 , hit the ground, I guess I didn't disarm quick enough and it went up in a flame, smelly too as it burned up the electric tape and prop piece I put under the tape to protect the ESC.

So I laughed it off as "no big deal, I can fix this" (i added a vbat buzzer, the receiver I had to solder, etc), and after seeing a video just replacing the ESC only, I thought it was cake!

I took the new Emax 20 amp ESC, soldered off the wires as I planned to use the existing wires though a bit burned, and it did go on with little issues

The new ESC had two signal wires, I thought I didn't need the ground signal wire so I removed that.

After all was connected, powered up, but it wouldn't respond to throttle like the others did, but did see it move a bit.

I then proceeded to desolder it and try again, I forgot to unplug the battery, and I not only was electrocuted, the ESC I assume was fried after sparks and smoke emitted from it.

Can anyone riddle me a tip?
