ZTE released stable Android 8.0 Oreo update build B20 for US variant Axon 7 A2017U. This is a SD Card Package update, so users will not get this Oreo update via OTA (over the air). Released on October 12, 2018, the B20 (A2017UV2.1.0B20) Android 8.0 Oreo update zip file download available at ZTE website, which you can flash manually very easily.

Since this is the major software upgrade, which upgrades Axon 7 from ZTE’s MiFavor skin to ZTE’s Stock+ Android build, all data you have on the phone will lose, so back up all important data, including photos and videos. The installation is rather a simple process and does not require a computer. All you need to follow the instruction below.
