1. The version type of the firmware is in the lower middle of the miner backstage interface, as shown in the Figure below:
2. Normally, the firmware type we receive should be: Release type, as shown in the Figure below. This is the official version of our official website firmware. Please update the official website firmware if your version is not of this type.
3. The non-Release type that often appears at present is Factory, as shown in the Figure below. This type of firmware is usually used for factory testing. Generally, it is impossible to change the mining pool miners. If your version is the factory type, please update the latest firmware on the official website in time.
*Note: There are many types of firmware, but the client should use Release; if not, please upgrade the official website firmware directly so as not to affect the miner's use.
