what model are you using?
Hi!
"what model are you using? "
C6603
best regards
You would have to downgrade to a FW which is rootable and then use the pre-rooted images to get back updated to 4.4.2.
Sadly this method implies wiping all your data on the phone.

Not all C6603 devices have unlockable bootloaders. Some carrier branded/supplied devices are permanently locked.

That's a new one for me
Some, but not all, carriers have requested non unlockable bootloaders for their devices.
O2 UK do this if I remember correctly and others in different countries also.
The OP almost certainly has a device originally supplied from a network provider.

Downgrade to 4.2.2 [ Built 10.3.A.0.423 ] FTF File Link
Use doomlords easy rooting method from here
then flash a pre-rooted 4.4.2 rom from here
H!
Thanks androidtweaker1!
And what's with my data and installed apps?

Downgrading requires wiping your data, so backup what you can.

Just out of interest, when an FTF file becomes available, could you then flash it with flashtool on a stock ICS locked bootloader?
Judging by past firmware updates, it's taken 2/3 months for Orange to push an update.
Yes, or you could flash the 303 generic UK and ota to current. You'll then get jelly when Sony says not ee.

I wonder how I flashed my V with its locked bootloader to Xperia VL's firmware using Flashtool, then.
All you need is matching signatures, and all similar models share them.

Sorry but you've got that wrong, you can use flashtool to flash an official ftf onto a phone with a locked bootloader, I've done it loads of times with my xperia's. In essence if your locked to a network orange, t-mobile ect then you can get the region generic ftf and flash it with flashtool to debrand your phone
What you can't do is flash custom ROMs which require a custom kernel.

Thanks for the responses guys, I thought it would be possible, the only reason I ask is that I've flashed ICS firmwares to the T in the past, but wasn't sure with it being a different version of the OS.

Please read before continuing to facepalm yourself.
Flashtool does not require your bootloader to be unlocked. It also does not even you require your phone ot be rooted.
Flashtool can be used on any xperia phone regardless. It does not require fastboot

Not always, there are ways around it. But in general yes.
Once the new firmware hits users with locked bootloaders we will see if we lose root, but then we will also find a way to root the newfirmware or find a way to update that does not lose root.
I have C6906 from Bell and i can't wait for bell to release 4.3
can i just flash unbranded 257 using flash tool
and use pc companion to update to 290?
my phone is not sim unlocked yet / never touched boot-loader / didn't even bother rooting it.
I am still on stock 534
thanks in advance guys
yes
As Greg already said - yes.
Branded version is same ROM but without a craps from your carrier.
So, not only you'll be able to flash it without any problems but you'll be very happy when you see that your phone is little bit faster and "cleaner".
Also, if you want to unlock SIM lock (if it's available on your device), you can do that by simple code order via Internet.

I've got the same phone from bell. First thing I did was flash an unbranded ROM. Bell has a few bloat apps that I hate. Best part is if you flash unbranded you don;t need to wait for updates. I got my update through PC Companion the day it was released.
Search the forums please.

I'm also on Bell with a c6906 and have done exactly what you are asking about and you will be fine. In case you didn't know we can't unlock our bootloader so the fix in 4.3 does not benefit us. Still 4.3 is a great update, loving the phone regardless.

Copy *#*#7378423#*#* to your phone dialer and it will open up a service menu. Go to Service info then Configuration. The last line in that screen will say Boot loader unlocked allowed: No
So we are outta luck.

Help a brother out
When the Z1 first launched, I was able to root the device.
I'm ignorant enough to not know if I had unlocked the bootloader.
General forum research tells me that if I'm not sure if I unlocked the bootloader, it means I didn't unlock the bootloader.
I updated my Z1 (C9606) to 14.1.G.2.257 Build.
I'm still running Android 4.2.2
Is there a way to root device without unlocking?
If so, could someone point towards the thread I need to follow?
thanks!

Hello,
flash back to .534 with flashtool then root and custom recovery your device and put a custom pre rootet rom on.I think that is the only solution also the same point as the threat starter asks for you only can use pre rootet roms for now.

Hello,
Is there a pre rooted UK generic unbranded rom to flash via flash tool on 10.4.b.0.569 (4.3)
Why a UK generic? There is no difference between UK, Italy,...
And if you flash an other pre rooted region you won't loose warranty

To actually answer the question, you won't find a prerooted stock rom in FTF format to flash with Flashtool.
Flashtool will only flash unmodified stock software in flashmode.
Here's a prerooted UK rom that can be flashed via recovery - http://forum.xda-developers.com/showthread.php?t=2590088

Thank you, so when I have finished this will I still be able to check for updates via pc companion, I don't mind if I can't actually install the updates but as long as I can check then I can flash back stock rom and update that way, can't I?
updates
To make myself clear lol can it still search for Software updates with recovery installed?
I once unlocked the bootloader with flashtool and noticed a software update on an internet page so I went on sony update service and it told me to connect in flashmode so I did then it said checking connected device then it said it can't update because the software has been modified, is this because of unlocked bootloader? I have relocked it and it could update I just wanted to know if it worked the same when recovery installed?
Yes, you should be able to check for software updates via the PC Companion. SUS gave that error because your bootloader was unlocked.
I cannot guarantee it though, as I rooted by unlocking my bootloader, therefore didn't use a prerooted rom.

Hey guys. I'm trying to unlock my booaloader of my Xperia Z C6603.
When I go to the service menu and check it says "Bootloader unlock allowed: No".
The point is, that I haven't bought my phone from a carrier, it's unlocked from factory and I don't know why I can't unlocked it
If it says "No", then it's permanently locked.
Did you purchase it brand new, directly from a store or used from a third party?

Then it's possible that the seller flashed generic software on a carrier supplied phone that they network unlocked before selling it to you.
You should contact Sony support and they should be able to confirm this if you supply your IMEI number.
