Locking custom LTE bands on ZTE MF286

My ZTE MF286 is running DNA firmware version B04. It's somewhat limited in LTE band selection, but that can easily be worked around with curl.
First of all authenticate to device using web browser. Otherwise these commands will return failure. You want to see {"result":"success"} message.

  1. Hi. Do you know how to lock that modem at LTE_A?

    1. Yeah, I would like to know that too. Does e.g. B20 and B3 only setting allows to aggregate them?

  2. Sadly these don't work anymore with B09 firmware.
