We've got good news for Axon 7 owners, Android Oreo 8.0 Build(B20) is ready to update and available to all users via an SD Card Update Package.
Please note that this is not an OTA (Over-The-Air) update and will not auto install. You will have to update your device manually via the Micro SD Card Package. Due to this major OS update from ZTE’s (MiFavor) to ZTE’s (Stock+) Android build, all data will be lost. Please back up all important information along with pictures and videos.
Daydream will not be supported with the Oreo update.
MiFavor Toolkit Removed
It is recommend, but not required that once the update is complete that you set up your device as a ‘’new device’’ and not restore from a previous backup of a Nougat build.
Instructions for Updating Axon 7 by SD Card:
This SD memory card based upgrade will erase all your personal data. Therefore, we strongly recommend that you BACKUP ALL DATA BEFORE UPGRADING. This would include your pictures, contacts, apps, and any other important files you have saved to internal storage. Additionally, you will need an SD memory card that has 2.5 GB of storage available.
Before proceeding with the update, you will need to enable developer settings and USB debugging on your device:
Enable developer settings and USB debugging
Go to your Settings and scroll down to About Phone.
Tap on the Build number seven times until the dialog box says you are now a developer.
Go back to the Settings menu and you should find a new option called Developer options. Click into the Developer options.
Make sure that the developer options are turned on and that USB debugging is checked on.
Make sure Enable OEM unlock is checked.
Now you may proceed with the Oreo update:
Step 1: Backup your device! Please use Android's built in backup feature or a third party backup program of your choosing. For more information on using Android Backup please visit: https://support.google.com/nexus/answer/2819582?hl=en

Step 3: Move the update package file, A2017UV2.1.0B20_SD.zip from your PC to your SD memory card.

NOTE: If your phone’s kill switch is activated, you would get an error message when you choose the“Apply update from SD card”. Go to Step 4 to delete your Google account to deactivate the kill Switch.
Step 9: Your phone is now updating, leave your phone idle until a message shows that the install has completed. It should read, “Install from the SD card complete.” Next you will be prompted by a new menu screen, using the “Volume Down” to get to the , “reboot system now”, and press the “Power Button” one time to complete.
