EC20CEFA no network registration after firmware update


I’m using an EC20 CEFA, I flashed the firmware EC20CEFAGR06A01TM4G_PSAP_BATE1117, the flashing procedure ending correctly, but now the EC20 is unable to register to the cellular netowk network.

I’m using it in Italy with Vodafone IT as operator.

Do you have any suggestion?

Thank you

If your module model is EC20 CEFA, please download the firmware of EC20CEFA and I will send you the shoulder pads by mail.

Thank you @FelixCheng-Q this restore my EC20 CEFA to work as standard modem, but it doesn’t work as PSAP, but the problem with the PSAP firmware versione was my modem version not compatible with the custom firmware
