In years gone by, Sony Ericsson would have all the extra bits to load on when creating a build for the operator. Certainly the operator didn't do it on its own. I am sure the others, like Motorola with its 'flex' software did much the same.

That would mean, say, Vodafone giving Sony the necessary boot logos, wallpapers, ringtones etc. The operator would then have to approve the update, which could take some considerable time as I'm sure we all remember. Meanwhile those with a SIM-free phone probably had their update months before, or even got updates that operators had stopped bothering with.

In more recent months, or even the last year or so, it seems the priority has actually been on getting operator branded ROMs out before the generic versions - so those who buy SIM-free are quite commonly finding themselves last to get updates. I can see why this makes sense, even if it seems rather illogical as it's the version with the least effort to produce.

Without the likes of Xda and flashtools, I'd probably be way behind on firmware updates as I never buy operator branded models!
That definetly wasn't the case in my time with the S3! I don't mind using the flash tool but I don't want my warranty voided considering I've only had the phone since Saturday!... Lets see... Still waiting...

Since flashing 534 I don't get notifications for Google. I auto sync is ticked for everything but I am not getting gmail alerts etc unless I manually go sync it again.

I have cleared data and it's still happening.

Sure Google were having major issues yesterday with mail. Whats it been like today as everything is working fine for me.

Today i flashed the official germany .534 update but there are no changes. Unlocked bootloader bug is still there and also boot up hangs as an all previous versions. I dont understand why they put so many updates in two weeks and nothing changes only ram improvements. I really starting to hate this device...

Well at least they fixed the headphones bug.. I'm quite sure they will release more fixes soon...

I bought my Z1 from clove.co.uk and I'm using it in the U.S. on AT&T. It is the C6903, should I flash the stock unbranded ftf?

So still no changes with the official firmware, this is turning into a farce on Sony's part.

As it's from Clove it will be running the generic (unbranded) firmware so yes flash the unbranded one, unless you like bloatware :)

I'm having the same issue! It's so frustrating!

Just to add to this - I flashed it this morning and alerts are working perfect.

So to keep my data I need to uncheck data, cache, and appslog correct? Do I need to check anything in the exclude section or the content section??

I downloaded the flashtool for Mac and it sees the device is connected but then it asks me to select the device model, and I don't see the C6903? Which one do I need to select?

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.

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.

Ok so I got the firmware file and the device file in the right place, but I can't get the phone into flash mode?

EDIT: Nevermind I got it :) flashing now

Power off your phone, wait 10 seconds, while holding the power down button connect your phone to your mac :)

m3dd0g says only better memory management but that's about it. All the bugs in 518 are still present with exception of the headphone problem that some have reported.

I have just gone back to 518 with the hope the UK version might get a better update but not holding my breath.

    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
