Any explanation on why this fixed my charging port?

This will sounds super schizophrenic but hold on

My charging port hasn't worked for awhile and I assumed it was because I had gunk in it

But when cleaning it out (multiple times, with multiple diffrent techniques) it never fixed my issue and my phone wouldent connect to cables

Today while being frustrated over not being able to charge my phone or be able to connect it to my pc via cable, I cleaned my port out again. And it did nothing. I have tested 10 plus diffrent cables that all work on all of my familes phones aswell as on other varied appliances, but not on my phone.

But after being upset that I couldent get my phone to charge normally after cleaning it out, I like kinda autistically stuck the razorblade I used to clean out my phone port into a cable that was plugged into my computer (cables not plugged into my phone obviously) and the cable archs out with a small ammount of electricity and i dont think anything of it as that was to be expected

But when plugging my phone in, it worked, connected and charged perfectly at any angle

And using diffrent cords, both on my computer or via a charging cube, all cords now worked to charge my phone

Why would sticking a razor blade into a single cable that had nothing to do with my phone fix the issue on my phone?
