dfu mode with android phone

just wondering if anyone has ever found a way to put an appletv 2 into dfu mode with an android phone and some ir app. (galaxy s5)
i have been trying them one by one but nothing seems to work for dfu. multiple buttons pressing doesn’t seem to work.
i have seen posted that people have done it with harmony but I don’t have one.

just an android phone.

anyone?
I have a silver remote somewhere but I like to do things the hard way if possible.
