Again: GPy modem not answering after firmware update

[Wolfgang Hottgenroth]

I tried to update the modem on a GPy to the most recent CAT-M1 firmware CATM1-5.2-48829 (https://docs.pycom.io/updatefirmware/ltemodem/), but after the first step the modem is not longer answering the anything. Step 2 of the update won't work, updating to NB-IoT firmware won't work, creating a lte object from the LTE class to run the proposed (https://forum.pycom.io/topic/4022/unable-to-update-gpy-modem-firmware/8) reset, disconnect, dettach cycle won't work, talking to the modem directly using the serial class with serial = UART(1, baudrate=921600, pins=('P5', 'P98', 'P7', 'P99'), timeout_chars=1) (https://forum.pycom.io/topic/6909/couldn-t-connect-to-modem-modem_state-disconnected/5) and so on won't work.

Do I have any other chance to revive the modem?

Cheers and thanks, Wolfgang

I am having the same problem. Is there a solution?

@Wolfgang-Hottgenroth Hi @pycom, is this issue completely irrelevant for you? No hint for me how to unbrick the GPy? Or is it actually lethally bricked?
