Downgrade or restore factory firmware

If you need to downgrade the version or recover the firmware, it's important to consider the type of control board, as flashing methods may differ. For example, boards with Amlogic processors require using an OTG adapter and flashing via the Micro-USB port, while boards with Xilinx and CVITEK processors can be flashed via the SD card slot.

Recovery instructions

Select and download the appropriate firmware for your miner (lists available below)
Format the SD card or USB drive in FAT/FAT32 format
Copy the firmware files from the archive and write them to the SD card or USB drive
Remove the media from your computer and insert it into the powered off miner
Power on the miner and wait for the green LED indicator, which means the procedure completed successfully
Power off the miner and remove the SD card or USB drive

The SD card capacity should be up to 16GB. If you're using a USB drive, its capacity should not exceed 8GB. It's important to use USB 2.0.

If you're unsure about choosing firmware for your control board, refer to the Control Board Types section
