Why can't I reset my phone ?

[Windows Central Question]

Recently, my phone started a new update, which I couldn't cancel, so some gears were showed on the screen and after that a sad smiley face. I couldn't turn on my mobile, every time I tried that the smiley face comes on the screen, so I tried to reset it with schedule of keys I found on microsoft.com but it doesn't work. What can I do now ?
