    I followed your instructions to update M3 to B350 using the SD card method. The 2nd update app didn’t work on C128 USA vers. so now I have Android 7, but not Bluetooth, or update app.

        I had to return my M3 to Amazon and start over with a new one. Do Not use any of these methods to update. Go to XDA developer’s web site and look up instructions for the ‘DNS’ method using the Firmware Finder app from the Google Play store to download the file. Then apply the update using the M3’s native update app in the settings menu.

          Hi Tim, I actually did more research hours after my post and came to your same conclusion ha. I however found steps on XDA to backroll to EMUI 4.1 and Android 6.0; bluetooth and updater are back. Decided to go with Firmware Finder as well to update safely. Thanks for responding!
