This article pertains only to those who have been instructed by Bobcat Support Engineers to manually upgrade their firmware. If you have not been instructed by Bobcat Support Engineering then your Miner 300 will not be registered to our management platform and you will not be able to upgrade firmware. If you are having firmware issues please create a support ticket here so that we can diagnose and if needed register your miner for a manual firmware upgrade.
You will need to have provided the MAC1 address and serial number of your device (usually via providing a picture of the sticker on the back of the unit) to Bobcat Support in order to have it authorized for this tool before the tool will work. Attempting this process before Support has registered your device to the management platform will result in a "SN not within valid range" or "SN not found" error.
