Phone is from Clove, so it's the "UK variant"

Is there some O2 branding on the firmware, for example some useless bloat software for O2 customers?

Anyone have the FTF file for the 14.1.G.1.518 (stock firmware)?

I think this thread should be renamed to something it easy to find if you want to find the "Sony official firmwares". It's just gonna be a mess when there n+1 different threads for firmwares

In this software menu you brought up, there in the service info there is a sim lock menu... How do you know if yours is unlocked? I get 0 in all the catagories... BTW, your phone is from clove so is it the unlocked one?

P.S: WTF, why is the O2 branded phone getting more updates? Shouldn't the unlock ones get it first!

    You need the device file for the Z1, it's located here in this forum somewhere but can't remember exactly where.

    I use parallels on my mac so have the folder but running under Windows 7.

    Sent from my C6903 using XDA Premium 4 mobile app

    Here is the device file for the Z1, drop it into devices in the flashtool folder, not sure if it will work on the mac version though. Like I said I use parallels and use windows 7 for all my flashing.

    Will flashing the new firmware wipe the phone?

    Nope. You can uncheck the option to wipe your device.

    I couldn't find Flashtool for Mac, which is why I was wondering how he had it. Also, I am a noob at doing things like to my device. The post you linked only brought me back here..


    Here is the link to the flashtool. You need to open up the .dmg and drag the flashtool icon to your applications folder.
    http://flashtool.net/download.html

    and you will need to open the package contents of the flashtool app and add this in there.
    View attachment C69XX.zip
    Unzipped of course.
    once in the package contents drop it in this directory /applications/flashtool/contents/macos/devices

    You will also need to put the .ftf file in /applications/flashtool/contents/macos/firmwares
