How to manually update tablet software for your S2 or S3 device

This article shows you how to manually update tablet software on your SIERA.AI device using the touchscreen interface.

Your device regularly checks for available software updates via its WiFi or cellular data connection. When it finds a new software update, it can generally update itself in the background upon an "End Shift" action. However, there may be situations where a manual software update is required. It is possible to update your S2 or S3 software manually in a few easy steps. 

WARNING: You must have constant power during the update process. Disconnecting power may lead to bricking of your device. On electric vehicles, make sure the vehicle battery is plugged in, for propane and IC engine vehicles please ensure that the key switch is on to supply power to the device. You may need to turn on the engine in certain IC/Propane vehicles to get power.
