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.

I contacted Sony and my phone was branded to Three UK, so I can't unlock the bootloader

Sorry to hear that.
Did the seller advertise it as an unbranded phone? Perhaps you can contact eBay to see if something can be done, even if it's some time after purchase. It's worth a try.

I was just thinking, what will happend if I try to unlock the BL with flashtool? Will it brick my device?

You cannot unlock a BL locked phone using flashtool.
If you want a different rom there are plenty of stock based custom roms just use the search function

It 100% won't work. You may soft brick the device, but most probably it will just fail with no adverse effect.

I found a new source in SONY Developer site:
http://developer.sonymobile.com/downloads/xperia-open-source-archives/open-source-archive-for-build-7-0-b-1-152/
Is this a new fw for T in future or what?
I hope not, because that is the firmware for the xperia TL (American AT&T) which has a bootloader that cannot be unlocked

"Cannot" as in never? or is this something that may change in the future? Because I just received my phone in the mail today, and this locked bootloader is very disappointing. I might just return this phone if unlocking is not an attainable option for me.

check the service menu. It will tell you if it allows you to unlock it or not. Its always worth a bit of reasearch about this before laying out £350 or getting into a 2 year contract....
If I just root my xperia z without unlocking the bootloader, will it void my warranty? Or installing custom rom with locked bl?

Root. Do whatever you want.
Need service? Flash stock before taking the phone to official service.
Same can be said about unlocking the bootloader.
But XperienceD is right, rooting DOES NOT VOID THE WARRANTY.

Wrong : The Free Software Foundation Europe argues that it is legal to root or flash any device. According to the European Directive 1999/44/CE, replacing the original operating system with another does not void the statutory warranty that covers the hardware of the device for two years unless the seller can prove that the modification caused the defect, accroding to http://en.wikipedia.org/wiki/Android_rooting
So even if Sony, or the president of the usa, or Thor himself said that void warranty, that's not true.

I've been there personally. Took my Xperia S, another Xperia S, an X10, and an Arc to service.
All rooted no problems.
I even took my previous Xperia S bootloader unlocked to have the screen replaced. Totally forgot to lock the bootloader. They yelled at me because I wasn't covered by warranty, but they kinda know me already as I buy all my phones over there (they let me play with the Z Ultra too ), they spared my life and didn't charge the 150€ they charge for having the screen replaced without warranty.
Sony service is great here in Spain, if you take the phone personally. Not so much when you have to deal with delivery system.
Awesome.!! but the Sony service rep here in India are kinda dumb. But I can deal with it. Thanks a lot for your help guys

Haha sure do it, it's totally legal to root your phone, even in India.
So even phones with unlocked bootloader, they need to prove the damage is because of the software we used! Am I right in this?

Yes and no. The service that is in my city is very clear about this. What they told me is that they need to register te parts replaced with their software, maybe serial numbers to keep control what goes in and out,, but they can't do so with the bootloader unlocked as they cannot flash stock firmware with the tools they have.

Wrong, a phone with a locked bootloader can be flashed by any flash tool made for Xperia Z, it's only if you unlock the bootloader that they can't (SUS and PCC don't work on unlocked bootloader), and btw that void the warranty to unlock the bootloader.
And yes they need prove that the modification caused the defect if any.

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.

Losing IMEI and SIM not accepted problems happen when you downgrade, not update.

Hi!
"what model are you using? "

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.

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.

I have the single sim international version of the z3+ and it says the Bootloader is unlockable in the service menu. So the question is how do I go about getting it unlocked?
Sent from my E6553 using Tapatalk
If it's indicated as unlockable, then there's no way to unlock it.
There should be instruction on Sony's website. Unlocking bootloader doesn't do anything for you unless you know what you're doing. It doesn't give you root access but erases your TA partition where you will lose all of Sony's DRM keys.
I'm aware of what unlocking the Bootloader does. Honestly don't care about drm or warranties as I never have phone long enough to break them anyway.

Sorry, I may have read it wrong and replied too fast. To clear any doubts, please indicate what exactly is stated in the menu. Is it "Bootloader unlocked allowed: Yes"?
In any case, this is the Sony site to unlock your bootloader: http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
That being said, I don't see why you would want to unlock your bootloader now. There are no custom ROMs or kernels developed for the Z3+ yet. You can't even root it.

Got a question
Got unlocked bootloader without possible root (5.0.2v 28.0.A.8.266 firmware E6533 (z3+ Dual)). Used flashtool before unlock and saved S1 Dump in Advanced menu. Is it possible to get DRM keys from S1 Dump and restore bootloader lock?
you should downgrade to the 251 firmware so you can flash the modded stock kernel for root access.im using imagebreaker kernel. check out zrom also
Ok pikeylfc,
I see that imagebreaker kernel is for e6553 device. Mine is e6533 (Dual sim)... I doubt if the same kernel can be used... It has different hardware.

Not necessarily. When you have active myXperia service, service tests will show, that bootloader is not unlockable. Try to disable myXperia (Settings -> Lockscreen and security -> Protection in myxperia (or something like that) -> disable/deactivate). Then reboot your phone and check again. It's high probability, that bootloader change state to unlockable in service tests. myXperia is asking you to turn on in initial configuration (if you have new phone or after wipe), and most people turn it on by default and forget it.
