HTC one m7 not updating to 4.4
My dad just bought a new HTC one m7 unlocked from eBay. When we got it we downloaded the update. When it finished downloading we installed. The screen the showes a phone with a green symbol with a blue line at the bottom. But halfway then the phone turns into a red exclamation point and then reboots to normal. Plz help I'm a beginner at this types of things.

Sounds like the update is failing during the install.
I wonder if the phone has been tampered with since you mentioned bought off eBay.
If you boot into your bootloader it will give you a Tampered flag at the top of its been hacked in any way.
