I have a Samsung Galaxy Note Edge, not rooted. It's currently on Lollipop 5.0.1. I've never been pushed any updates between that and Marshamallow. I am trying to update it to Marshmallow now, but it fails within the first minute. The error code is 404. Normally, a 404 error is for a webpage unavailable. Is that the same thing here? If so, when might it be resolved so I can update? If not, what can I do to fix the issue? I am using a wireless connection and my battery is fully charged, btw.
