I have done some more testing and now realised every MC7455 modem I try to
update is now stuck in "low-power" mode and I can not get it out of it.
Although the mode should not be persistent over power cycle it is. I will
see are there any other AT commands I can try to get out of that state.
I also got a different error a couple of the times I tried today:
loading device information before the update...
setting firmware preference:
firmware version: '02.24.05.06'
config version: '002.034_000'
rebooting in download mode...
download mode detected
error: error creating device: unexpected response received in dload sdp:
