The process of formatting and transferring the image to the memory card will begin.

If successful, the line with the SD card will turn green.

If the recording fails, the line with the memory card will turn red. In this case, make sure that the memory card is healthy and is not currently being used by other applications.

When you try to view the contents of the memory card with a file manager, the memory card will appear empty. However, the data for the miner firmware is present on the card and is located in the unallocated area of the partition table, before the main partition, which you can see in the system

After successfully formatting the SD card, you can start miner firmware:

• Turn off the miner.
• Gently insert the memory card into the corresponding slot on the miner panel with the contacts up until a characteristic click, while you will feel a slight resistance of the slot mechanism spring.

This action does not require tangible effort. If the memory card is not inserted, try turning it over and inserting it the other way.

• Turn on the miner.

The process of flashing the miner will begin, accompanied by a flashing red indicator ① (“Active” и “Alarm”) on the miner panel. After the firmware is finished, the green indicator②.

After that, you need to turn off the miner from the network and remove the SD card from it - otherwise, at the next start, the miner will start the process of writing the firmware again.
