Thanks for the suggestion. The firmware upload fails with the same
error if I try to upload an older version of the stock firmware. The
latest version of the stock firmware (which is the version that is on
the router I have) is 2.0.1.

I next tried setting .soft_ver to "soft_ver:2.0.1\n" and
"soft_ver:2.0.1 Build 20170103 rel.71053\n" in the AD7200 section in
tplink-safeloader.c, but neither worked.

Attaching a serial cable is a good idea, but it will be a week or two
before I can get that done. Do you have any other suggestions?
