My friend, if you are going to update the gateway or another control unit, always do one thing and turn on the 4 flashers so the car doesn't fall asleep. In case he falls asleep with the 4 flashers on, it allows communication via OBD.
Units that require 4 turn signals connected, gateway, onboard network, ABS, instrument panel, engine control unit, infotainment, practically almost everything, even with the Odis E.
