The firmware has changed several time since summer of 2014. There is
also been a memory layout change.

All UV-5R radios (and it's many variants) since BFB297 (starting with
BFB299) all report BFB297 in the [3] key + Power-in message. This
message is no longer useful for determining the firmware version.

You radio either has a firmware version format that CHIRP is unaware
of or you have one of the few radios that Baofeng has shipped that has
no data in the 14 bytes that CHIRP uses to determine the model and
version of radio it is working with.

Either attach a debug.log file here or email it directly to me and I
will take a look at it.
