I have been having audio problems with my Lumia 920, people sometimes couldn't hear me. Before trying to bring it to the closest Nokia Care centre, some 80 miles away, I went through the trouble shooting guide on the Nokia website. It give the usual advice, which ended in a factory reset. I backed up the photos, etc, and went about it via Settings > About > reset my phone.
It seemed to work as expected, showed cogs turning, so I went out to the shopping centre for a couple of hours. Came back and the cogs were still turning. A quick search online said that it shouldn't be the case, it's just too long. So numerous advice has been followed, from
Volume Down + Power
Volume Down + Power + Camera
to a sequence of
Volume Up, Volume Down, Power, Volume Down
None of these worked. The best I can do is get it to the charging/low battery icon. So I let it drain, took out the SIM card and now have it on to charge. It is showing the charging icon, but it doesn't seem to be actually charging.
Is there anything that I can do without having to make the trek 80 miles away (or have to post it off)?
