Sony Xperia XZ1 O2 Firmware

[SkittlesMcVite]

Good Morning All,

Is the official O2 Branded firmware available for download?

Does anybody have a link to the official O2 Firmware, in order to enable wifi calling with O2?

I've brought a standard Unlocked XZ1 which doesn't have the O2 firmware so I am unable to use WiFi Calling.

Many Thanks in advance.

You can use a software like Xperifirm to download every single firmware

You don't need a branded firmware to get WiFi Calling working with O2. In Germany (customized DE firmware) it works out of the box! :good:

Which country you are using your XZ1 in?
