Hi andreas,
Sorry for the late reply.
If your air602 still can accept AT command , please follow the instruction below.
Step 1.
Send the command via serial tool below to enter the flash write mode:
</s>AT+&FLSW=5000,11<e>
Step 2. Close the serial port in the serial tool, then use the Luat_Tool to download the AirM2M_Luat_V0010_W600T_USER.FLS(maybe you shuould download it twice)
Now you can use the firmware V08 or V09 or V10.
If your air602 can not accept AT command , you should pull pin PA0(GPIO13) to ground before you power this module.
Then you can use Luat_Tool to download the AirM2M_Luat_V0010_W600T_USER.FLS(maybe you shuould download it twice)
You can find the AirM2M_Luat_V0010_W600T_USER.FLS here
