Looks like this EM7455 does the following sequence:
  --> Get Operating Mode
  <-- Low power
  --> Set Operating Mode (Online)
  <-- ERROR: invalid transaction
 
I manually run a FCC auth command through qmi-proxy and it went online right-away.

Oh, looks like QMI translation is wrong. The error is really "InvalidTransition", which makes more sense.
Comment 2 Aleksander Morgado 2017-02-28 10:38:07 UTC 
Fixed in git master, mm-1-6, mm-1-4.
