Default [Q] why do I'm unable to upgrade to kit kat?

Hi,
I have a 4.3 installed on my phone, I woul upgrade to 4.4, but I don' know how to do that.
If I check with pc companion, ittell me that there is no upgrade, and the same by OTA.

I'm wondering if is it possible that I'm still out of upgrade.

How can I upgrade it...?

TIA

Renato

Is your Z1 a UK unbranded one? Uk unbranded seem to be always the last one to get updates. You could back up your phone then perform a repair. Doing repair may wipe your phone so consider before doing it. BTW you have posted in Q&A section. Please move to Q&A Moderators many thanks

If you can't post in the correct section you are unlikely to know where the search button is either...

If you have root or unlock bootloader on your device you cant upgrade it through SUS or PCC. Lock it back or flash it via flashtool.

This is incorrect.

If you have root you can still update via PCCompanion or SUS, but you will lose root.

If you have an unlocked bootloader then you cannot use official tools such as PCCompanions or SUS, you can only use EMMA (Official tool from Sony for unlocked bootloaders)

ok, I thought I can do it with OTA or pccompanion. I thought it is a "regular" upgrade for Z1. Indeed I need flashtool? I need to root Z1 ?

You will be able to use PCCompanion once the update becomes available for you, they are not all released at the same time, it can roll out over a month or two.

In the meantime, you can flash a FTF using flashtool from flashtool.net and there is no need for root. It is just a repackage of an official download and made avaialable for all.
Find them in the FTF mega collection thread.... Use the search button.
