If you need to update the version of vnish firmware which you are already using on the SD card or in NAND you need to download the firmware WEB SD update file and use upgrade function in the firmware.

Standard types of control boards: Xilinx ( SD slot outside ) , beagle bone BB version ( SD slot is located inside on the control board) , Amlogic ( only micro usb slot is located outside ), CVitek ( SD slot outside ), check the file types of control boards

After rebooting a miner with a CVitek control board running Vnish firmware, the stock firmware will return. To prevent this, the Vnish Toolkit must be running and connected to the miner network, so that Vnish remains active after a reboot or power-off.

Instructions for installing stock firmware using recovery SD images (amlogic, xilinx, beagle bone, cvitek control boards):

1. Use a USB flash drive or SD card up to 32 GB, formatted in FAT32. For AMLOGIC control boards, it is recommended to use an OTG-USB adapter instead of an OTG-SD adapter.
2. Download the recovery SD image for your miner model and control board type, then copy the files from the archive to the root of the USB flash drive or SD card.
3. Connect the SD card or OTG adapter to the powered-off miner.
4. Turn on the miner and wait until the green LED on the front panel lights up and stays on. This means the firmware installation has been completed successfully. The process takes no more than one minute.
5. Turn off the miner and remove the SD card or OTG adapter with the flash drive from the control board.
6. Turn the miner back on and wait for it to boot — the firmware should now be updated.
