[AC Question]

Hi,

I'm considering buying an international Z5 and using it on T-Mobile, since they no longer carry Z3 and will not get Z5.

There is supposed to be a Marshmallow update for Z5 in January, so I want to make sure that I'd be able to download it without any issues. Since the carrier won't be pushing it out, I'm looking to find out

- what the availability would be like (available as soon as Sony releases, or wait for someone to mess with the file and make it usable, or any other delays)?

- what is the installation process (would I have root or just install over Lollipop since the update would be for that specific phone?)

Thank you!
