I tried renaming the file to
AD7200v1-up-ver2-0-1-P1[20170103-rel71053]_2017-01-04_10.08.28.bin to
match the latest stock firmware and the web interface still didn't
accept it.

I now have a header soldered to the four pins labeled JP4 but so far I
have not been able to get serial communication. Do you happen to
remember what the pinout is?
