Question about the bootloader - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hello, i'm considering in buy a brand new Z3C online (from my carrier discount program), how ever i can't use any device without CM13. I wonder if any Z3C can have the bootloader unlocked.. and if not, if someone have a way to unlock the bootloader without the Sony method.
I can't check if the device i want to buy can be or can't with the dialer code as it would be bough online.

Impossible to say, if it's a sim free network unlocked device they supply then there's a good chance it'll be unlockable. The only network I know of that supply sim free network unlocked device's for both payg and contract are three UK. Without checking the device before buying it's a lottery basically.

Thanks. In the past, my carrier was well know to be the only one in the country with unlock devices that they sell and contract free. I'll call then and ask if it still is like that (i think so).
Also, a guy said that it is possible to install custom ROM with a locked bootloader... far as i know it isn't true. I'm right, or this guy is?

Bootloader unlock allowed: No.

Hi everyone, first post, go easy on me
Anyway, I picked one of these up at the weekend and I'm very happy with it, but I'd like to try the new roms that are starting to appear. Unfortunately, I'm not able to unlock my bootloader (Bootloader unlock allowed: No). This is on Three UK.
Is there ever likely to be a workaround for this?
I'm gutted
I have the same thing on mine (T-mobile Croatia), I reckon it's a network carrier lock.
But if I have faith in something, then it's in XDA, the place where people turn "you can't do that" into "you can, it's just that no one found a way for it YET"
Let us be patient and see what will happen.
mine is the same
Bootloader unlock allowed: No.
Same here on O2 UK. I've just arranged sending the XZ back to O2, with this being one of the major factors that made me decide to wait for the S4. Shame.

I can't root my device
That's why I got my phone from a third party (CPW/P4U/etc) they nearly always supply generic handsets that are unlocked and bloat free.

Yup. Always purchase unlocked devices. NEVER count on a manufacturer's locking mechanisms being broken, nor on the lock mechanism returning somehow. (Qualcomm's secure boot infrastructure is quite strong, so it's rare for it to be compromised unless the OEM handset manufacturer screws up. Since the T's locking was never defeated, I wouldn't hold much hope for the Z.)
Vote with your wallet - don't buy a device unless it's unlocked. If you buy a locked-down device and rely on "unsupported" locking mechanisms, you are implicitly saying that you are OK with locked-down devices.

AW: Bootloader unlock allowed: No.
Branded and/or sim locked Sonys are usually not unlockable. This is documented well enough.
As Entropy said, either buy generic devices from the open market which come slim and neat to begin with or go with an operator which doesn't sim lock or brand devices sold by it.
I can recommend mine, sells devices subsidized if you wish yet still unlockable and the only branding to be found are a different SI than "generic", so I only suffer from delayed updates and nothing else

I bought a outright supposedly unlocked Xperia TX for a Sony Central store in Sydney then only to find out it was actually vodafone stock with a locked bootloader.
Hi, can some one help me out here.
I have a XZ which has unlockable bootloader. I have unlocked it and rooted and installed recovery kernal and Xperia Z Revolution rom. All ok.
Now, was just seeing if I ever needed to send phone off for repairs.
So downloaded the lastest flashtool and was successful enough to restore back to the 10.1.A.1.350 Original Sony Unbranded UK Rom.
With flashtool you can now lock the bootloader, so I went ahead and did this but now when checking the bootloader status, it says "Rooting Status: Unknown" and when entering my unlock code in CMD "Failed <remote: Command did not succeed>
How do I fix this so I can unlock the bootloader again?
I don't think your locked. You probably are still unlocked as we cannot relock bootloader yet

Yes I will do, just need to get my post count over 10 before I can post in the development threads.
Don't want to bother people with PM's either.
Let me know how it goes. I was thinking of unlocking and relocking. Out of curiosity. Is your bravia engine working now that you relocked

Hi all.
First of all let me explain myself, I am a noob but not a total idiot so I am where I am through rational consideration.
I have renewed my contract on three UK, which has just expired. The number one consideration for me is that I have full, unlimited access to the internet with tethering and the only option for this in the UK is on three, on the contract I was already on. Three have an excellent 3g network and are in the process of giving DC-HSPA access and will get LTE-4g before the end of the year. I am guaranteed to automatically get the higher speeds when they are available, still with unlimited tethering at no extra cost. No other tariff can give me all that in the UK. There are sim-only options but they are all short term and do not guarantee me the unlimited tethering I require into the future, and there is a good chance the cost of these tariffs will increase when 4g is rolled out. In short the only option was to renew my contract.
So, I have renewed my contract and got the XZ. The XZ was the only option really after seeing all the developers struggle with Samsung phones and with all the developer friendly support promised by Sony. Whatever I did with my contract I wanted the XZ and I love it.
I knew when I signed the contract that I was taking a gamble on the locked bootloader, but the best option for me was to renew my contract and if the bootloader is locked sell the phone and use the money to partially fund the buying of a bootloader unlockable XZ. I knew that I would probably have to do this and was ready for it when I got the contract. Anyway the bootloader is unlock:no, so I will be carrying out my plan and this XZ will get sold to fund the purchase of an XZ with unlockable bootloader. I am OK with all that and if I sell the XZ for even half it's current value I won't care and will have still made the most financially sensible choice. I will have to buy a phone off contract, but I will still have the tariff I want. If the phone I have had come with an unlockable bootloader I would have been a couple of hundred quid better off, but I had to have a phone on the contract anyway so whatever phone I got would have had to go to get an unlocked XZ. Even if there was a tariff which gave the same allowances I would have had to pay for the handset anyway, and it would have ended up costing more than it is anyway. There is no such tariff anyway and I have made the sensible choice and am happy.
Now on to my question. Obviously I am working up to selling this phone, and figure it will be easier to sell sim-unlocked. Fortunately I live in the UK and network providers are obliged to allow you to unlock your sim. On three I have to wait thirty days and then they will unlock the sim for me. I have decided that the thirty days older the phone is will be offset by it being unlocked and being easier to sell. I am not in a rush to flash roms yet so I get the phone for a while and sell it for the least effort, hopefully when CM is pretty well ready for the phone.
Anyway, all is well and good and I am content.
However there is one possibility I have only recently considered. I am aware that sim-unlocking is a completely different thing than having bootloader unlockable:yes. But I was curious to know if a byproduct of getting the Sim officially unlocked by Three would be a change to the bootloader unlocking status. I don't know enough about how all this works, and as I say, I understand there is a difference between getting the sim-unlocked and the bootloader thing. But might the bootloader lock be somehow dependant on the sim-unlock status. ????
I only ask this out of curiosity.
I will find out for myself soon enough as I will be getting the sim unlocked ready to sell anyway. It will save me a bit of money and a bit of hassle if the bootloader becomes unlockable and I won't have to part with a phone I have become attached to and know is a good one, it doesn't have any of the issues some people seem to be having with their XZ's.
Either way in a couple of weeks I will have an XZ with an unlockable bootloader as CM has become a must for me.

I am getting mine unlocked by my carrier. Three UK. It's £15, which is expensive but I would rather have it done officially. I have filled in the form but it looks like it might take a week to get the actual code from Sony.

All phones can be unlocked if the carrier agrees. For example, in Japan you can pay NTT Docomo like 3000 yen and they will unlock it.
But...
1. Unlocking it doesn't make it work on all frequencies magically.
2. Even unlocking the SIM may not enable certain other features (i.e. tethering, etc.)
3. If you really want it unlocked, you should buy the unlocked version to begin with.
I didn't want that carrier option . I'm actually from india and wanted to buy a carrier locked XZ from US or canada to use here in India (via my relative living there) . Also can i buy a phone on contract and ask for it being unlocked there and then while paying something, let's say 15 20 dollars ?

I had to renew my contract anyway, and am happy with what I have got. It is the same as I have been on for the past couple of years. The phone was very cheap on this contract. I am unlocking it to sell it so I can get an XZ with an unlockable bootloader. I will still be using the same provider. I am in the UK so the XZ works on all the right frequencies for me. I have absolutely unlimited tethering in my contract, that is why I have the contract.
I agree with your basic thoughts, but it's horses for courses.

[Q] Any Telus Users Want To Help Me Unlock My Boot loader?

I recently bought my Xperia Z1 online and Love the phone but can't unlock my boot loader. When I bought the phone I hoped that unlocking would be allowed but sadly it was locked. I found out that my device is from Canada and under the carrier Telus. I spoke with Telus and they told me that they charge 35 bucks to unlock boot loader and since I am with At&t with the C6906 they told me that I would need an active account to unlock but I was going to buy a sim and get a prepaid plan but they ship no items to the USA. So Im aware that it is $35 but I will pay whomever does this for the 35 dollar charge plus 40 dollars for your time and it should not even take an afternoon to help me unlock. So if you are a Telus user and able to invoice me the 75 dollars via PayPal or some other means I will gladly pay. ???
I don't think they would really unlock your bootloader though... As far as my experience with sony since 2011 nobody has yet manage to unlock a locked bootloader even thru network operators. I think what they are talking about is network unlock which reps usually mistake between bootloader unlocking. So better sell it and get a real unlocked version instead.

It's already a SIM unlocked phone and I already spoke with Sony and they informed me to talk with Telus because it's carriers that request that bootloaders come locked. I called Telus and they told me that they had no problem providing the boot loader unlock code but I needed an active account to charge the fee. It's even on the Telus page somewhere where it states the fee for unlocking the boot loader.

That's the keyword there "Unlock Code" There's no unlock code when unlocking sony's bootloader. You generate a unique key file by executing some fastboot commands on your phone. An unlock code is used to unlock a network locked phone. Hate to be a bringer of bad news but network reps tend to have this reputation about misinforming you when it comes to technical details such as this. Once you say the words lock and phone they instantly associate it on network unlocking regardless of the other info you mentioned.
We are sorry to close your thread!
Your Bootloader is locked permanently and cannot be Unlocked.

Get an unlocked variant, usually, carrier locked devices can't be unlocked...
If T-Mobile does offer the 5a, and if the TMO 5a can have the bootloader unlocked (likely but not guaranteed), it will first require a permanent SIM unlock and wait 40 days (apparently). Normally TMO won't permanently SIM unlock a phone before it is paid off (and a temporary SIM unlock will not allow a bootloader unlock). You could either wait the two years for the phone to be paid off, or you could prepay the balance on the phone. Prepaying the balance greatly reduces the financial advantage of buying through TMO. If you are a long-term customer of TMO you might be able to convince a service rep to do a full SIM unlock for you, but the cases I found of this were for multi-line customers who clearly were not going to change networks. Just buy an unlocked phone from Google or Best Buy.

Question S23 AT&T to SIM Unlocked ?

Hello,
I have gotten a new S23 (regular), which was a freebie from AT&T. My friend decided to be gracious and to give me one, however I am still dealing with SIM unlock. Is it possible it download a firmware like -U1 to work with my current carrier in Japan?
It's possible to flash it to U1, but it won't SIM unlock the device, just change it to the unbranded software. If you want it SIM unlocked, he either has to pay off the phone (its free after monthly credits) or you pay whatever shady service on Ebay to unlock it for you.

He traded a Note 2 for the phone (There is a deal at AT&T for any Samsung phone comes a free S23).
Yeah, after bill credits. Once the phone is paid off, they'll unlock it.
