Hi everyone. I currently have a MC7455 that looks like it had some old firmware on it. I was having some speed and connectivity issues so I thought a firmware update would help. I have this modem plugged into a windows 8.1 desktop. After the firmware fails, I cannot connect to a cellular network, even after power cycling it. I just want to make it work again.
Diagnostics tab, it shows:
ATQ0V1E0 - OK
AT+GMM - MC7455
AT+FCLASS=? - 0,2.0
AT#CLS=? - COMMAND NOT SUPPORTED
AT+GCI? - COMMAND NOT SUPPORTED
AT+GCI=? - COMMAND NOT SUPPORTED
