Hashcore Toolkit installing firmware

Attention:

You need to check the date of your stock firmware. Then follow these rules:

1) Stock firmware versions on which you CAN install Vnish directly using the toolkit: February 2024 and earlier, and from December 2024 to August 2025.

2) Stock firmware versions on which you CANNOT install Vnish via the toolkit: September 2025 and newer.

3) If your BITMAIN firmware is from March 2024 to December 2024 and you cannot find and install the stock update file up to September 2025 on your own, you need to use the GUIDE for installing the stock SD image for your model and control board type, and then proceed with installing the Vnish firmware using the TOOLKIT.
