- Make sure you have Enabled OEM Unlocking and USB debugging on Axon 7 device from Settings > Additional Settings > Developer Options > OEM Unlocking.

Step 1: Download the full stock firmware (update package file) from download section above.
Step 2: Transfer the A2017UV2.1.0B20_SD.zip file to phone storage or SD Card.
Step 3: Now, to avoid FRP Lock, you will need to delete (remove) the Google account from the phone. To do so, go to Settings > Accounts > select Google > tap 3 dots on the top right corner of the screen > select the “Remove Account” option.
Step 4: Reboot into recovery mode. Turn off the phone completely and then simultaneously press and hold the “Power” and the “Volume Up” buttons. Once you see the Recovery mode option release keys.
Step 5: Now, from the Recovery mode select the option “Apply update from SD card” using the hardware keys like Volume down and power key to select an option.
Step 6: Navigate to the update package stored in you SD Card or internal storage. Select the A2017UV2.1.0B20_SD.zip and press the “Power” button to confirm.
Note: Kill switch is activated when there is an active Google account running on your phone. If you would get Kill switch error message, delete your Google account from Step 4.
Step 7: Your phone will now start the upgrade procedure. Once done, you should get the message something like “Install from the SD card complete.”
Step 8: Reboot system once complete.
Note: For users who don’t see the option to apply update from SD Card, can also update by sideloading the update package using the option “Apply update from adb” found in recovery mode.
