AC Question
I have a HTC M9 running Android 7.0 (HTC update 4.14.401.7). I am in the UK with EE as my carrier. My phone has recently been requesting I download 4.28.401.3, an update of about 650mb which is supposed to bring security updates and system enhancement. The phone is however refusing to install it. It gets to 25% and then switches to a red triangle with exclamation mark. After about a minute it then restarts and requests I download the update again. I have tried removing my external memory card, the sim card and have tried a factory reset. Nothing has helped. Any suggestions on what to do next would be greatly appreciated?
