gPy modem bricked



  • Hi there,
    Maybe someone was successful in upgrading modem firmware or recovering from below state.
    I was trying to upgrade firmware to the newest version... it failed, and now I cannot use lte.

    >>> from network import LTE
    >>> lte=LTE()
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    OSError: Couldn't connect to Modem
    

    When I'm trying to run firmware update again - it also fails:

    >>> sd = SD()
    >>> os.mount(sd,'/sd')
    >>> os.listdir('/sd')
    ['updater.elf', 'CATM1-41065.dup']
    >>> sqnsupgrade.run('/sd/CATM1-41065.dup','/sd/updater.elf',debug=True)
    <<< Welcome to the SQN3330 firmware updater [1.2.5] >>>
    >>> GPy with firmware version 1.18.2.r7
    File /sd/updater.elf has size 430284
    File /sd/CATM1-41065.dup has size 6160982

    Please try to power off your device and restart in safeboot mode.
    

    Is it completely bricked?
