I started to suspect this is in fact a hardware issue. I had a very similar behaviour after I have flashed Flyme OS on it. However, I can't be 100% sure because it died again during the first charge under android, with the same "stuck on a percentage" behaviour as it did under Ubuntu. I cant restart either it using the very same procedure I have used the first time to confirm this behaviour. Any of you affected by this bug had sudden device power off's?
