I can NOT get my #Bitaxe to update firmware.

I've tried using the web installer (stuck on "preparing to flash")

I tried CLI (md5sum does not match flash)

And I tried the direct interface over local network (stuck at "working...")

I got release 2.5.1 from the GitHub repo, changed permissions to exectuable for the file, opened ports for the web installer, and probably other things I'm forgetting.

Help!
