OTA will probably fail because of modified /system.
Update through PCC will most likely remove root and recovery.

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.

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.

How big is that OTA update?
Try, if you can flash it it could work and you could actually preserve root, maybe even recovery but in 99% of cases you'll get error.
OTA update can't be flashed on rooted device (but, as I said, there were few times it actually worked if it's small, few mb update)
But this is update from 4.4.2 to 4.4.4 so I doubt it'll work.

OTA updates with root are fine, but you may well lose root, just as you would flashing a FTF or updating via Pccompanion.
The issue with OTA updates is if you have an unlocked bootloader.

That's not correct mate.
Try to downgrade, root and install recovery then try to update via OTA - you'll fail.
Only one or two OTA updates worked on rooted Z1.
I have rooted Z1 with locked bootloader and OTA will always said - error while trying to flash, update your device through pc companion.
I'm 100% certain...

OK, the few times I tried it I had no problem, but I have only ever done it a couple of times..
It's 154.5 Mb, my bootloader is still locked only my device is rooted so I will go ahead give it a try and see what happens if it fails or I lose the root I can again downgrade and root right?
Yes, but you can also just root the FW anyway

If you want to update, then download FTF. You will loose root. Or use NUTS pre rooted rom. If you want to root yourself, look over to cross development and use easy root tool v8. Then also download nuts xzdual for locked boot.
I tried to install OTA update for my Xperia ZR.
The update is downloaded when i try to intall..the install starts but will not proceed.

removing the bloatware from the system is the reason why it doesn't work! The updater recognizes the missing files and aborts the update, so the only way to get the Ota update is to bring the removed apps and files back!
I'm facing problem with OTA update from 14.5.A.0.242 to.......... 270
It said could not verify update. My Z1 is already rooted and BL locked. Thanks.

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,
