Even though PC Companion is showing that your phone has an update, if you try to perform the update, you will get an error that the software has been modified (because of unlock bootloader) and you cannot proceed.
If you want to update a phone with unlocked bootloader, you need to use Sony Flash tool.
Note that updating via PC Companion or Sony Flash tool, will result in your root being lost.

I reinstalled pc companion and hard reset, but never tried Emma flash tools, I guess it needs unlocked bootlader and don't think I have it. Will it harm the phone if I try, anyway? Thanks

[Q] Update To 4.3 from 4.2.2

Hey guys i just bought Xperia Z1 C6903 on 4.2.2 Global-LTE_14.1.G.2.257 and i'm afraid to update it because some phones died after update, so how can i update it without any problems? please answer if you now dont just say maybe
THANKS!!!!
The phones died most of the time trying to root and downgrade. Just use Flashtool v0.9.13 and download the latest FW for your model from HERE, wipe Data, Appslog and Cache and all will be fine, or wait for OTA, but there is no difference.

Just use SUS or PC Companion. It is safe way to get updates for your Z1.

The point is if he do not have Updates or he do not have the latest update and want to update then he have to use Flashtool, anyway flash from PC Companion or with Flashtool there is no difference, they do the same thing.

It says he got global version so he should get latest updates through SUS or pc companion. From what I can see hes phone is not carrier locked with bloatware. Flashtool is best for every locked and unlocked versions. It just sounded like he is afraid of using it, and that was bases for suggestion to keep it safe...
yeah this is it , but do i lose my stuff using flashtool? Please if you can give me the .FTF file that suits my phone
I can now update using PC Companion but some people posted on the thread that their phone died from this
I pressed thanks for all of you

HERE you find all the FTF for your model, choose which you want. I will recommend a Unbranded one.
To keep Apps and Data just uncheck "Wipe Data" in Flashtool and you will not lose anything.

[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

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.

it does this because you have altered system file (i.e. root and/or recovery)
Hi,
Try updating from PC Companion software, it won't take much a time if you have a good internet connection. Keep in mind you'll lose root and OTA failed very likely due to a modified system partition (root).
All the best,
