Thank you for getting back with me Dpaz, hoped maybe you had found a cure to this problem. Looks like many of us are in the same boat regarding the flobbed lollipop update. Blue tooth issues and quick charging not functioning. Supposedly, and according to various knowledgeable sites, there should be an update coming very shortly but no definitive date as of yet.

 

Here's likely the most current, and comprehensive information regarding the Marshmellow update... and it looks like good news!

For my HTC M8 looks like anywhere between now and Feb!
