GUIDE 03 / VERIFICATION

Verify a downloaded build

Every published build carries a SHA-256. Comparing it confirms that the file matches the SHA-256 value in this catalog, and that nothing rewrote it on the way.

Why it matters

Firmware is the deepest software in the device. A file from a mirror, a chat forward or a partly finished download can look identical and behave nothing like the published build. The checksum is the only cheap way to know.

Get the published value

It is printed next to every build in the download table and inside the route passport in the finder. It is also in the machine-readable catalog at /api/v1/firmware-catalog.json.

Compute the value locally

macOS and Linux

shasum -a 256 vnish-s21-aml-nand-v1.3.5.tar.gz
# or
sha256sum vnish-s21-aml-nand-v1.3.5.tar.gz

Windows PowerShell

Get-FileHash .\vnish-s21-aml-nand-v1.3.5.tar.gz -Algorithm SHA256

Windows Command Prompt

certutil -hashfile vnish-s21-aml-nand-v1.3.5.tar.gz SHA256

Compare

MatchInstall it. This is the published build.

No matchDelete the file and download again from this site. If the second download also mismatches, do not install it - write to support with the model, the build id and both values.

One origin, no mirrors

Every build on this site is served from the official release origin with its own checksum and board route. We do not publish mirrors, and a file that did not come from here is not a file we can vouch for.
