NAND INSTALLATION: Download the NAND image and the Hashcore Toolkit utility (extract the archive and read the installation guide).

SD INSTALLATION: Download the SD image, extract it, and read the installation guide (To install the firmware, use an SD card no larger than 16 GB, FAT32). Insert the SD card with the Vnish image and power on the miner — if you remove the SD card, the BITMAIN firmware will be restored. If you need to update the version of the Vnish firmware already installed on the SD card or in NAND, download the WEB version of the Vnish firmware and upload it using the UPGRADE function.

VNISH FIRMWARE UPDATE: Download the Vnish Online Updater (VOU) to quickly update your firmware to the latest version without downloading any additional files.

Vnish firmware for Bitmain
( - ,)


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

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
