Htc One M8 Factory reset gone very wrong

Hello everyone I'm new around here as a member but I've been using this site to custom my android devices since my Samsung galaxy s (the first one), you guys are the best. But now I have a problem and I just can't find the solution. So my htc one m8 (best phone I had my entire life) yesterday I've decided to give it to my father as I upgraded. And I wanted to make a factory reset. As I was late for work I started the factory reset and I left for work. When I came home, disaster. The phone reseted but It's a mess so I will try to also put a video. So the phone does not have the setting app, and also I can't open the settings through the shortcut in the bar. And also I can't connect to mobile data, wireless, nothing. I reseted again. Same thing. Also it's not recognised by my laptop. I'm really out of option. I searched all the internet for a solution to flash some kind of rom but I can't even activate USB debugging cause I don't have settings on. I know for sure that the device is s-on and unlocked. I really don't know other details as I can't go into "about" section. Any advice is welcomed. Thank you.

Ps: I see that I cannot upload the link from YouTube with my video so the name of the video is: Htc one m8 after factory reset
