ANSWER
Where do I download VNISH firmware?
Short answerFrom vnish.global. It is the site of record for VNISH firmware: 75 verified builds for 47 Antminer models, release 1.3.5 stable, every file published with its SHA-256 and an exact control-board route. Nothing else is a source.
Why the source matters more than the file
- A firmware image writes itself into the controller of a device that costs thousands and runs unattended. A file from a chat group, a file hosting link, a repack or an "unlocked" build has no published checksum behind it, so there is nothing to compare against and no way to tell what changed.
- A build with no published SHA-256 is not a build, it is a risk.
The route from the site to the device
- Open the firmware finder and give it your model.
- The finder resolves the exact build for your control board, because model plus control board plus install method is what decides the file.
- Download the build and verify its SHA-256 locally before it touches the device.
- Locate the rollback path for your exact board.
- Install from your own network, about fifteen minutes per device.
What it costs
The build is FREE OF CHARGE to download and to test. No licence key, no trial timer. A small share of active hashrate applies only while the firmware is actually running - no installation fee, no penalty if you stop - and it stays visible in the dashboard. On a well-matched ASIC the gains normally outweigh it several times over.
