    I recently bought an AT&T HTC One M8 and it was on KitKat. I updated it to Lollipop via RUU. I downloaded the marshmallow RUU file and attempted to update it. When it started, it would stay on 0% and it would say Checking Header. Then it would say Error 155. HTC Sync Manager won't detect my phone and it says Error {4}. My phone is in original condition and has not been rooted or anything similar to that. My computer is a HP Pavilion G4 with Windows 10 installed. Any help is appreciated.
