Which stock firmware versions can VNISH be installed on ?

ATTENTION: You need to check the stock firmware date. To check the date, open the miner using the IP address in the browser address bar.

Firmware can be installed using the Toolkit on stock firmware from February 2024 and earlier, and from December 2024 to August 2025. You CANNOT install VNISH firmware with a date from September 2025 or later. If you have BITMAIN firmware installed between March 2024 and December 2024, you can update the firmware to a date before September 2025 using the stock web update file. If you cannot find the stock update file before September 2025, you will need to downgrade the firmware using an SD image.

IMPORTANT: Amlogic control boards (a113d) with firmware from September 2025 and later cannot be flashed using an SD image. You must first unlock the USB port and then downgrade using the SD image.
