Carrier unlocking - Xperia Z Q&A, Help & Troubleshooting

I am getting my xperia z tomorrow off eBay. Apparently it's locked to three UK. Now this clearly means that the boot loader is locked and at the moment not unlockable.
Hence I was wondering if I pay three the £15 unlock fee, how will this affect my boot loader status? Will it change to unlockable? Does Sony have a CID system similar to the HTC One X that will intervene with my ability to get timely updates from Sony (I.e. some HTC CIDs got jellybean a lot later than others)?

As stated in all such previous threads for every other Sony phone that gets released... Chances are, you will NOT be able to unlock the bootloader. That's why the international, non-carrier units from hong kong, Singapore, etc, are so popular.

Mine was locked to three and had it unlocked through them and the bootloader stays locked

Branded phone bootloader question

Hi, I've looked around but not been able to find anything that really answers this question.
I'm tempted to buy an Xperia Z when they come out in the UK. Unfortunately it will be a branded phone (there is no way around this unless I want to pay alot more money).
My question is for 3UK customers with an Xperia T. Are you able to unlock your bootloader using Sony's official method? I have read that simlocked branded phones can be nearly impossible to unlock on certain networks.
Thanks for any help.

Not true.
I have a branded vodafone T and I can unlock. I would suggest you speak to 3UK and ask them, and if they cant answer your question take your business elsewhere.
I made sure I could unlock with vodafone before renewing my contract with them.

I have an Xperia T on 3UK, and it is very much locked. However, I have debranded it using the stock UK ftf and flashtool - and I am really quite enjoying using the Sony provided ROM.
Not sure if that helps, I suppose it depends how much you would like to muck about with your phone after receiving it!

Not sure with regard to your query about 3UK branded phones being bootloader locked however I understand that Carphone Warehouse phones are generally unlocked to any network and allow bootloader unlocking. If you were to get a phone from them on a 3UK contract then you should be ok - when I was looking for a T I popped in and queried this with them first and they suggested all of their phones are sold unlocked regardless of which network contract you choose. Phones 4 U have a similar approach but don`t offer deals on the 3 network.
Vodafone keep their phones SIM unlocked that's why you could unlock it Greg... But with carriers like 3UK they brand and SIM lock hence no CM goodness for me

Sim unlock and bootloader unlock have nothing to do with each other. You can have a sim locked phone and unlock the bootloader, and you can have a sim free phone and not be able to unlock the bootloader..and every combination in between as they are independant of each other

But fastboot locking is, or at least was in 2011 line, and unlocked by way of certificate replacement which unlocked everything, but sold as SIM unlocking causing confusion.
I think even with unlocking code from network, fastboot will remain locked.

If a carrier has made the bootloader unlockable then having the code from sony will not unlock it.
If the carier removes that restriction that allows the bootloader to be unlocked AND removes sim lock then tha is the carrier merging the two locks. They could just remove the bootloader restrictions AND keep sim lock if they want.
You can get an unlocked bootloader phone that is sim locked and vice versa. What carriers do with their locks is what they add to the phone after android and after Sony have done their thing.
They are still independant from each other unless the carrier has merged them, so my point stands, ask the carrier if you can unlock the bootloader. If the sales persone does not know what that means then go elsewhere. If they so not its not possibel because of sim lock they are lying as it is possible, its just maybe needs a bit of effort from them to be bothered. Then take your money elsewhere.
I have been into plenty of phone shops and they look confused when you ask them these questions, I just take my my business elsewhere and get what I want.

Except that with any Sony Android phone I am aware of, if the device is sold SIMlocked, it is not whitelisted in the bootloader unlock database.
While the two are technically independent, it is pretty much unheard of to see a Sony device that is sold with SIMlock but has an unlockable bootloader, and similarly, you never see devices with a non-unlockable bootloader but no SIM lock.

I stand (semi) corrected
Hmmm it's not looking good then.
Unfortunately my device will have to be 3 branded (for reasons I'm not going to go into here).
I think I will probably contact 3 and see if they can shed any light on what to expect.
It's not the end of the world I guess, I can still put Apex on there and make it look how I want if I don't like stock. Nice to have the option though.
It would be stupid if SIMLock would be on and bootloader lock off cause u could easily remove SIMLock.
So in this case bought are related but in opposite direction - not. Cause I got SMS Code to remove SIMLock but that didnt made my bootloader unlockable.
To bad Orange is the only operator in my country which locks bootloader in Sony devices. (wish I'd knew that before signing contract)

I can confirm that the 3UK Xperia T is bootloader locked (no fastboot). I rang up Three and they said that it is not possible to allow bootloader unlocking on it (gave me a bull**** excuse about warranties and such, and I explained how I am aware than bootloader unlocking voids the warranty and that is the same for all phones).
However I do suspect that it depends on who you speak to as to what answer you'll get.

Why dont you just follow the instructions from their website......?
If your device says Bootloader unlock allowed: No Then they will not do it,

Three UK Bootloader

I'm thinking of pre ordering the Z and I'm just wondering about the bootloader.
I've read mentions of the Three version (which is the LTE version) coming with a locked bootloader. I'm just unsure of the scale of the problem; my previous phones All came locked but that didn't stop some xda genius unlocking it for me. Will non-Three devices just come pre-unlocked, with the Three version just requiring a bit of extra work? Is the Three version even in unlockable? (Bad question to ask before it's even out, sorry)
I'd greatly appreciate if anyone can clarify the above points
My Xperia arc bought 2 years ago has a locked bootloader, I can't answer whether SIM unlocking it will unlock the BL too.

I got it coming on Three UK too. If the bootloader is fully locked then it will be going back, simple as that.

I've put the question forward to them on Twitter but I bet they'll say they don't know.. They should know stuff like this though, no excuses for not knowning.
*Update*
@ThreeUK @ThreeUKSupport Hi guys, could you tell me if the Xperia Z will have a fully locked bootloader with you guys?
@gez_morgan @ThreeUKSupport It will be locked yes <Jo
Then I told them I'll be cancelling my pre-order in that case and they replied with
@gez_morgan Just checking for you. Will keep you posted
@gez_morgan Hi there, yep this will be locked.
Just to clarify,
No Sony phone comes with unlocked boatloader.
It's UNLOCKABLE bootloader which is the key word. All sim free phones are unlockable. i.e. you can go to Sony developer site and have it unlocked for free after entering your imei number. When Sony do this they check that the imei is that of an unlockable device.
When sony chose to become developer friendly they allowed the unlocking of bootloader but because of agreements with networks they wouldn't unlock carrier locked devices. Hence when you go to service menu (phone dialer - *#*#7378423#*#*). You will see the status saying "unlockable bootloader= No."
Even if you unlock the sim lock on your phone it will NOT make your bootloader unlockable by the official Sony method.
So as an answer to OP 3UK phones will not have unlockable bootloader by official method unless for some reason they decide to provide sim free phone rather than their locked ones. WHICH I GUARANTEE THEY WONT.
It won't be the end of the world though, because afterall we are in a developer's site and some incredibly smart guys on this site will eventually be able to hack the bootloader for ALL DEVICES.

S-ON/OFF is HTC.
I am new and I found this out myself it isn't hard.
Sony Bootloaders decide if the phone is easily modified (ie. rooted, abled to flash roms/kernels easily). The Bootloaders are all locked from stock, and are "unlockable" depending on if your phone was from a carrier. Carriers determine if your bootloaders are locked, so the chances are if you purchased direct from a Carrier online shop then no, it will NOT be unlockable. Usually the case as I have read is that if the carrier usually SIMLOCKS the device, then it will be NOT unlockable. This is because the carrier already processed the phone and added the simlock etc.
Carphone on the other hand if you have bothered to Google. Usually sell unlocked/sim free stock. This is because the nature of how they work. They stock simfree stock because they will need to hold less stock since they don't need to hold X amounts for each network that way. Simfree stock means unlockable bootloader.
I currently with Three and on a monthly rolling contract which include the all you can eat data. Anyway I am currently using Sony Xperia V sim free phone and bootloader status is Bootloader Unlock allowed:Yes.
I currently looking to upgrade to Sony Xperia Z/ZL sim free. Yet I course I had to pay hundreds of pounds for the smartphone but I can change smartphone, unlock also I look to rooted locked which can be achieved as I do not want to break the BE or music download info in walkman etc. Also signing with contract phones with Three I think you three animation at boot time which I do not want, I can end the contract for another contract is another factor.
So you see some of the reason for choosing a monthly rolling contracts rather than 12/18 long contract you sign up for and no choice but to stick with it until the end of choice once signed on dotted line.
I think you find the Sony Xperia sim free smartphone bootloader are actually locked but you get a status bootloader unlock allowed:yes therefore you can and have to unlock it yourself.
It when you choose to buy these Sony Xperia phones on a 12/18 month contract that are locked and you get the bootloader status it cannot be unlocked as no.
My advice is choose monthly rolling contract with Three which I think is great.

Had a hard time reading your message but i skipped to the last 2 lines. No not all contracts are bootloader locked. Carphone have said and confirmed all phones sold by them (unless obviously stated) are unlocked sim free stock. This will mean you can buy any contract from them and the phone would be a sim free unlocked phone with the bootloader unlockable = yes.

WRONG/not entirely correct.
bootloader unlocking and rooting are different. Usually in most cases with xperia phones in the past a decent dev, -usually by the names of doomlord, bin4ry, or other usual suspects , find an exploit to root a certain firmware version, without the need to unlock bootloader. So whether that firmware is locked to 3 or is sim free is irrelevant. You should still be able to root, provided someone has been able to find the exploit.

You could just go to Carphone Warehouse, almost all their phones are unlocked sim free phones no matter what network or contract/payg you go with. Just ask to make sure before you buy (they occasionally have had locked ones from what they have told me before) and they will let you know, the Xperia Z will be unlocked as far as I know.
Just bought an unlocked XZ for £309 from smartfonestore, thanks guys

That's interesting. Three in Ireland sells XZ with bootloader unlockable. I checked and it says:
Bootloader unlock allowed: YES
Does anybody know if Meteor Ireland sells XZ with unlockable bootloader?

will the z1 be carrier locked in the UK?

Specifically o2. I'm on a three contract but also have an o2 one up for an upgrade. I want to use my three sim in the o2 z1.
If you get it from O2, it probably will be carrier locked!
Handset I have from EE is carrier locked, and bootloader lock alllowed is NO.
Doesn't look to be the end of the world, when a lot of Sony stuff relies on the bootloader being locked. DRM keys and that.

Hi, I'm from Mexico and bought a Z1 in Telcel plan (the original model was 6906) I have about 4 years using phone android, I wanted the HTC One but take long time to get here to Mexico, so desperate and buy me this Z1 and I'm really disappointed as I do not understand why some models like mine can not unlock the bootloader, because among other things I can not flash any custom room, or having a good kernel tweaks. (I really love Carbon room) All this regardless of the phone too easily scratched screen, and failures of touch sensitivity on the right edge, I guess be for the location of the buttons.
anyone of you know why?.
Sorry about my bad english.
Thank you.
Because your phone is on Contract and they locked the Sim and Bootloader for security. One day when the contract expire or your phone get old you will be able to unlock sim but no bootloader. It's a deal made between your Carrier Network and Sony. If you buy a Unbranded and Sim Unlocked Z1 you don't have this problems.

That is not true !
Stop leading people the wrong way !
I bought my Z1 branded and sim-locked and i was allowed / able to unlock my bootloader. So, what you said has nothing to do with reality. And by the way ... could you tell us how you got that information?

It is in that way but no all the Carrers Applay that method. Just google it. This argue was mention 100 times on XDA too.
OMG

Why some Z1 models can not unlock the bootloader?
Thanks, there are many topics dealing with this but there is no a clear answer, I already flash one room unbranded but 6903 because as I said the original model was 6906 so I have unlocked the sim, I read out there on xda that taking it to sony service, as has unlocked the sim, they can change unlocking bootloader allowed: NO by Yes.
I'll try this way.
Greetings.
It's about specific negotiations between Sony with each Carrier
Telcel decided they wanted to keep the bootloader locked, thus C9606 will be permanently closed.
There are ways around this, but it WILL void warranty.
Good luck.
I'm currently evaluating unlocking bootloader as well.

Unlocking Bootloader will avoid warranty in any case, Yes or No, buy actually the Developers on XDA they saying is no way around and you can't unlock if the Bootloader Unlocking Allowed is set up to NO. So when you buy a phone from a any Carrier make sure the Bootloader Unlocking Allowed is set up to Yes.

Here in mexico punish us with prices, sony officially sold the Z1, at $ 1000 usd (no brand) With a 2-year contract I could get $ 350 usd in telcel. Besides, very few models get really good, slow to arrive and bring an outdated firmware. Google does not sell their phones officially. But I want to unlock the bootloader because I am almost certain now that the bugs are resolved that brings z1, soon going to release a firmware google edition for z1 (I really wish it) and I need to unlock the bootloader to install.

Check your bootloader, just write *#*#7378423#*#* and go to Service Info > Configuration > Rooting Status if there is Bootloader Unlock Allowed: NO probably you can't unlock your bootloader. Call Sony Center and ask if this is possible but no guarantee about that.

Are you positive about this?
I was under the impression you could get around the locked bootloader even if the device says No.
I'm not sure if I even want to try because I would permanently lose the Bravia Engine should I succeed. I'm not sure what it's supposed to do, but it sounds nice.

if the device says unlocked bootloader: No, then it cant be done.
sim lock and bootloader locked are depends on your carrier, there are carriers that they have locked the sim only and still allows bootloader unlocked.
but some carriers locked both. you can get a phone which allows to unlocked bootloader, if you buy a free sim phone or bought not in the carrier contract but from other store like sony store or any store that sells free sim phone.
please dont make things complicated.

With Unlocking Bootloader you will lose X-Reality, which is not a big deal anyway because it not improve the images, and Bionz processing but actually this not influence the functionality of the camera at all. No body said about Bravia Engine, I hope not.
I am from Mexico too. My bootloader is not allowed

Hahaha....what a crazy answers...
Guys can't tell what's the difference between SIM and boot lock but are here first to be smart....
I must say, I feel in love in XDA when I was on my Xperia S, now... I just wanna hit my self with some blunt object...
Of course, thumb up for all nice people here...

any luck yet?
I just wondered if anyone had gotten any news from Sony as to if the bootloader on a not allowed model van be unlocked in anyway?
I'm aware that threads exist and ppl are flashing roms on handsets with locked bootloader but I think those are allowed to unlock theirs.
Is there still no way to unlock bootloader on disallowed models either officially or unofficial?
I want custom rom
Just to add a little clarity to this, gregbradley helped me a lot with this.
If you've bought the phone from a carrier then there is a distinct chance that the bootloader unlockable status will be a flat no.
What does this mean?
This means that you will never (unless someone cracks it, highly unlikely) be able to unlock your bootloader.
If you bought your phone from certain carriers (like 3 in the UK, or so i'm told) or from third parties like carphone warehouse in the UK, then you WILL be able to unlock the bootloader, as the status for unlocking the bootloader will read "Yes".
If you see a yes then youre in luck, if it reads no then you most certainly will not be able to unlock the bootloader.
Further to this, Sony will not help you with this whatsoever, I have asked and asked and got little more than a scripted response, they WILL NOT help you to unlock your bootloader.
The sim being locked to a particular network means nothing to the bootloader, it's simply a coincidence that third parties who have bootloader unlockable phones are too sim free.
Hope this clears things up for people who weren't sure.
AFAIK, it is at the carriers request that the bootloader is in this state, not Sony's, probably why they won't help with it, but that's a guess.
double post.

You can still have all the goodness of custom roms m8, you just won't be able to flash kernels like doom kernel and or AOSP rom's and CM10 based roms.
In all fairness, youre not missing out on too much, but I was the same when i had a locked phone, the grass always appears to be greener on the other side until you realise it's actually not.
