Firmware update of MC7455 timing out.

[Paul Gildea]

Thanks guys, setting the firmware to the default or Verizon image that came
pre-installed worked fine and I regained my radio power modes.
Unusual that I can't upgrade to the official latest firmware on the Sierra
Wireless site (the versions do seem to match somewhat SWI9X30C_02.24.05.06.cwe
and SWI9X30C_02.24.05.06_VERIZON_002.034_000.nvu). I'll try and play around
to get them on there somehow.
