Yes you can, but there are more ways to have a disaster and "brick" your MG-35 if you upgrade over the network. If you use one of the recent versions produced by Gadgetmind, you are safer because (1) it omits the bootloader and (2) it's a little smaller and faster, so your window of vulnerability is shorter. Point #1 is the big one, though, because you can totally mess up your firmware and still recover via serial cable since the bootloader never gets erased.
