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.
I call provider support.
I have a problem with TCP server Connection. There’s some topics reporting this works with previous version. so I try to downgrade from version 5.5.25 to 5.5.23. This operation hangs the modem, the format of the flash have changed. There is probably a another problem before the downgrade, because another modem with version 5.5.25 is all OK.
