Default HTC One wifi and bluetooth problem

Hi there

My problem is that my HTC One is unnable to connect me to a wifi... actually it cannot start the wifi at all... neither the bluetooth... it is stuck on "Turning on..." and like that for a few days... I've tried reset, wiping the cache even the squeezing test but none of them gave results... it is still on "turning on...".
Please help me with that because a lot of people are having the same problem. There are solutions where u can rename your phone to HTC One but I CANNOT EVEN DO THAT because the "WiFi Direct" (from where u can rename it) is gray and unclickable.
Thank you in advance!
