Hi,

This FW upgrtade changes some setting related to the serial port. That is some ASC0 lines are change to GPIO in the initial setup.

Please, Truy to acces to the module over USB to change the settings of ASC0 to "std" to be able to use the serial port again

Regards

I encountered the same. 

Execute these commands on the serialport;

AT+CSCS="gsm"

AT&W

AT^SCFG="GPIO/mode/sync","std"

AT^SCFG="GPIO/mode/ASC1","std"

AT^SPOW=1,0,0

AT^SLED=2

AT^SCFG="Serial/Interface/Allocation","1"

AT^SCFG="Gpio/mode/DCD0","std"

AT^SCFG="Gpio/mode/DSR0","std"

AT^SCFG="Gpio/mode/DTR0","std"

AT&W

UPDATE

Also you need programming tool which allows you to upgrade the firmware and JRC seperatly. Bacause of thed changed characterset the tool is not able to install the new JRC.
