Can't update via mobile network with Nougat

[Gabriel83]

Hi people, I've just updated my Xperia from Marshmallow to Nougat via 4G mobile network. No problems, but then I tried to update a new minor Nougat update, and I only can via Wifi, not mobile network. Is any way to deactivate the wifi option, and update via mobile network again?. I don't have wifi near.

Thanks and greetings from Argentina.

turn off wifi and turn on mobile data. then try and tell me what happen are you able to update or not. Some mobile data network dont allow to download more than 100 mb file.
