O2 Z4 SGP771 stuck on 5.0.2 is it possible to put Nougat on it

[scribblesvurt]

I have a O2 Z4 SGP771 3G stuck on 5.0.2 is it possible to put Nougat on it? I don't mind invalidating the warranty. I don't want to put a custom rom on it. Just the standard genuine firmware.

Thanks,

Scribbs.

I've run into the same problem. Moreover, I have found that when I type in my tablet's IMEI at http://support.sonymobile.com/gb/software/ the page responds with 'No information available'

Seems to be a problem at Sony.

Please, contact the Sony Mobile support so that they can fix it. The more requests they receive, the faster they will fix it
