If the cloud upgrade fails on your device or the upgrade has made your device go offline the device can be restored manually.  To upgrade the device manually you will need a microSD card and physical access to the device. For more information on how to manually upgrade the firmware, please refer to the information provided below. 

Note: Before upgrading the device manually you will need to downgrade it to revert it back to its original state. Ensure the device is powered on during this process and the microSD card is properly formatted to FAT32 before proceeding. For more information on how to format your microSD card click here.
