ATTENTION: Check the stock firmware date, if you have BITMAIN firmware from March 2024 and newer you need to downgrade the stock firmware date using recovery image for your model and control board type, download unlock x21_recovery images for 21 series, unlock_L9 for L9  series and unlock x19, l7_recovery images for 19,l7 series.

To install the vnish firmware, you need to use the TOOLKIT. If you do not know what model and type of control board you have, then you need to download the HASHCORE TOOLKIT FULL PACK (includes firmware for all models), the toolkit will select the necessary firmware itself during installation. You can also download the HASHCORE TOOLKIT + nand install file in the form of a firmware selection for your model and control board type.

To upgrade to the latest version use  VOU – vnish online updater , the utility scans your network, determines the miner model and installation type and automatically updates to the lates version
