I follow the procedure to update the firmware (->5.5.23) via AT command. The beginning seems ok : +WDSI:3, +WDSI:12, +WDSI:14.
No +WDSI:16, automatic reboot.
Now on the developer kit, the TX light stay on and i can’t communicate with the modem.
Is there a method to restore or retranfert the firmware.
