All the above I tried to do for my controller thinking it would never work again, but then with all hope lost I got my usb c charger(because I have a series x controller) and plugged it into my Xbox then to my controller and it stopped blinking when I got the charger in the right position, then finally my light stayed on, I tried using buttons and they started working again then I unplugged my controller from my Xbox and it worked, so guys don’t think it’s broken and get a new one just try everything possible first because I was ready to give up but then it started working in the end.
