I’m having the same issues on my HTC One M8. I cannot connect to any of my accounts on it. I tried to reset it and the wdrt tool does not work for me, it can’t detect my device in HTC boot loader mode. I tried the ie proxy settings, and signing in from ie does not work either! Someone please help me.. :( I just bought this phone only to realize that it’s a brick the happens to have a web browser. It’s my first windows phone, too. It’s on WP 8.1 btw.
Someone, please help. 😢
