The Golden Rule:

Only download UBNT firmware from Ubiquiti’s official community portal or direct CDN links. Ubiquiti does not host old firmware indefinitely, but archived versions are available via the Ubiquiti Firmware Archive (requires an account) or through trusted mirror sites that checksum files against official SHA256 hashes.
