Re: HTC ONE not charging and Usb not recognizing !
I started to get this issue last Friday, and have been back to normal since late Monday.
I contacted HTC and after jumping through many hoops of fire, I uninstalled a game (Clash of Clans) that was making my phone run extremely hot and followed one of the suggestions that was given by the HTC rep.
I turned fast boot off, turned the phone off, and hold down volume up and down and power for 2 minutes. This made the phone reset about 8 times. After letting go the buttons the phone booted, didn't start to charge. I turned off developer options, restarted the phone, switched back on developer options (make sure usb debugging is on). Finally I plugged the phone to the charger for about half an hour, I got the 'usb host mode enabled, charging not possible' message, I turned my phone off and it started to charge normally. No erratic blinking charging screen where it would jump up 4% every few minutes. After noticing this I turned the phone on and, thankfully, it's been working great again.
In my last email with the HTC rep I was told to get in contact with tech support to arrange to send the phone in... I have about 7 more months of warranty, so for now I'll just ride it out.
As pissed off as I was with my phone when it started with the weird stuff, all the love came back when I saw that little red light telling me that it was charging again.
Sorry for the long post, wanted to share this in case it might work for one of you guys.
