I know, but did you check which version you would install with that? It was an old version. All I'm saying is, that Canaan is really bad in providing support.
What version exactly are you expecting? The most recent one is the July firmware, which is included in that package; no new version is yet available.
According to this post below Canaan will start releasing open source firmware starting in December they didn't mention anything yet to release a new version for this unit.
