I tried to upgrade ION7400 firmware from V1.3.1 to V1.4.3 but failed.

Is there anything wrong I got the firmware from website ION7400_MID_V001.004.003.upg ?

Hi Yut - MID firmware should not be upgradable - are you sure you want the MID version?

I don't know if 1.4.3 firmware supports DLMS but I managed to zip a version and uploaded to the ION Setup box location for firmware: ION Firmware - Box

Thank you very much.

The 1.4.3 does have DLMS  but have to use advance setup to configure. Setting is not available in Setup assistance(the ION8800 does).
