Sadly the only firmware combinations I can seem to get to work only talk
about a "4G LTE Connection", which [of course] doesn't work.

It does seem that the device retains its firmware unless *POWER IS LOST*
- as in disconnect the power cord AND the battery.  So that might
explain why it worked before.  It must have still had the firmware from
the initial Windows installation; and we've now no way of identifying
which/what firmware that was.

The HP Qualcomm driver package doesn't seem to contain a UQCN.mbn file -
only lots of amss.mbn & apps.mbn files.  So I was stuck with the Lenovo
firmware images, the incomplete HP firmware images, or a mix-n-match of
both.

I have to give up at this point.
