Check for a Wi-Fi connection issue: Check the Wi-Fi connection status of Solarbank and MI80 (if there is any), ensure that the Wi-Fi network has been configured for your device and is on, and check that the device is online. If the network connectivity is poor, you can temporarily use your cell phone as a hotspot instead of the Wi-Fi network to do the upgrade.

If the Anker APP reports that the upgrade failed, the device will still try to complete the remaining steps. In this situation, wait about 10 minutes and verify the device version.
