Vnish S19, T19 firmware

How to install

Special offer for owners of 200+ ASICs!

ATTENTION: If you have BITMAIN firmware from March 2024 and older, you need to download the file 2024 UNLOCK for your control board and read the instructions inside the archive for installing the VNISH firmware.

There are several options for installing the firmware. The first option is to install using SD card, the second option is to install without the SD card directly to NAND of the miner using the VNISH TOOLKIT

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

SD CARD: Download the SD IMAGE , unzip and read manual ( Use SD card to install the firmware (not more than 16gb, FAT 32) Insert the SD card with VNISH FIRMWARE and turn on the asic, if you pull out the SD card the BITMAIN firmware will return. For amlogic control boards you can pull out an SD card or USB flash drive. 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.

NAND INSTALL: Download NAND INSTALL IMAGE for your miner model and type of control board and VNISH TOOLKIT (unzip, read manual how to install).

After rebooting the miner with the CVitek control board with the vnish firmware, the stock firmware will return, you need to scan the network where the miner is located using phoenix-scanner in the background and the Vnish firmware will be restored automatically
