  4. Hi there,
    I have a Huawei E5573 and and have tried the unlock codes created and have only got 6 attempts remaining. When I try to upgrade the firmware the the software is looking for a comm port but when the device installs it does not seem to be allocated a comm port? Is this normal? I cannot seem to be able to carry out any of the firmware steps and just putting in the codes generated just seem to use up my try’s..
    The modem is locked to O2 network in the uk.
    The Software version: is what it is at at the moment
    Hope you can help
