How to unlock bootloader????? - Xperia Z2 Tablet Q&A, Help & Troubleshooting

first off, thanks for your time and reading this!
I have the Z2 LTE Tablet. it was on a carrier network, EE. I paid sim-unlock £17 so I could get it to all networks.
here's my problem, it's on all networks but the bootloader says "allowed: no" is there nothing I can do??????
I have tried flashing different firmwares etc and different regions (do I always set them up as UK?!) and I've had no luck!
what should I do?!?!?!?!!?!

There is nothing you can do, some you cannot unlock the boot loader, which has nothing to do with getting unlocked.
Mine is the same way, unless someone figures out how to do it unofficially, your boot loader will remain locked.

I think you're mixing up "unlocking" with "unlocking bootloader"? They're two completely different things, mind you!
Unlocking the bootloader is for installing custom ROMs, such as "Cyanogen Mod".
"unlocking" is to be able to use your phone with other carriers.

[Q] Wll updating or debranding or modding unlock the phone?

Will updating or debranding or modding xperia x10 unlock the phone, it was locked to Rogers Canada but I unlocked it recently with an unlock code? It is running 1.6, any advantage of debranding or updating to 2.1 is enough for now. Thanks
No, the only way to unlock the phone is through an unlock code. debranding simply takes the branded bootscreen off, and allows you to have generic firmware, so that when ota uodates roll out, you don't have restrictions imposed on them by your carrier (or the carrier the firmware was through rather).

Hi All,
There have been many confused members (especially the noobs) who do not understand the difference between unlocking and debranding so I wanted to start this thread to clarify this matter once and for all.
Debranding/Flashing: : This is when you flash some firmware other than your original operator's FW. For example, if you have an AT&T or O2 branded X10, when you flash/debrand generic fw (or any other fw of your choosing) you simply get rid of the "branded" software pre-loaded on your phone. Hence, the term "de-branding". This does not mean that your phone is unlocked. You will still have to use your original operator's SIM card, like AT&T or O2, to use your phone EVEN AFTER flashing/debranding your handset.
Unlocking: This is when you "network unlock" your phone and are able to use it with any GSM operator you choose other than your original operator. For example, you have an AT&T or O2 branded X10 and you want to use it on T-Mobile US or UK, can you do that after simply flashing/debranding? The answer is NO. Why? Because your phone still requires a special code to be entered before it becomes network unlocked. For further reading, please go here.
FAQs:
1. If I flash to generic firmware using Bin4ry's flash tool, will I unlock my phone?
No, you will simply debrand your phone but, you will still need to get the unlock code.
2. If I debrand my phone and then unlock it but, I would like to go back to my original branded firmware, will my phone become re-locked to that network again?
No, once you unlock your phone, it will remain that way no matter what firmware you flash in the future.
3. How do I know if my phone is network unlocked?
The simple way is to pop in another operator's SIM card, for example you have an AT&T branded X10a, then you can use a T-Mobile SIM card. If your phone reboots and you do not get a "enter code" screen and you see that you are connected to the T-Mobile network then your phone is network unlocked and can be used with any GSM operator.
Another way is to go into the hidden service menu. In the lock screen (the one with the swype animation) press the following sequence of buttons (Home, Back, Back, Home, Back, Home, Home, Back). If you are on 1.6 replace Home with Menu. Then go to service info --> SIM lock. In the top line, if you find this [X] Network 10, then your phone is locked. If you find this [ ] Network 10, then your phone is unlocked.
4. How can I get my unlock code?
There are a few sites from which people were successful in getting their unlock codes like MobileInCanada and CellUnlocker. There is also a thread by Xda-member "Lancez" here who can provide unlock codes for a fee. Currently, there is no known method of unlocking your phone for free.
I hope I have clarified this matter for everyone.

[Q] Help with unlocking bootloader on Live (WT19i)

I have been trying for two days now to unlock the bootloader on a friend's Live with Walkman (Wt19i) with little success.
The phone came with firmware 4.0.2.A.0.58 and is branded so in the *#*#7378423#*#* /Service info/Configuration menu, the rooting status is :
Bootloader unlock allowed: No
Rooting was easy, thanks DoomLord.
Next is unlock bootloader. I tried to do this via the s1tool method because the official Sony method was a no-go because of branding.
The s1tool method seemed like it would work but then I read that it also doesn't work on branded phones.
I attempted it anyway - the result was no change whatsoever in the phone's bootloader status.
Can I unlock the bootloader without having to pay someone to do it?
The s1tool method might work even if the phone is branded but if you want to unlock the boot loader to flash custom kernels and roms you will need to enter to fast boot mode which is disabled in all the branded phones that I know of, you can try to enter the phone in fastboot mode turning it of and connecting the USB cable to the PC and the phone holding down the volume up key, if the notification led turn on blue then you can flash custom kernels and rooms once the bootloader is unlocked if not then you will need to pay to unlock it if that is what you or your friend wants.
Hope it's helpful!!
Thanks for your reply, very helpful indeed.
I will see if I can boot into that mode when I get back home and at least then I'll know for sure.
It would be ever-so-nice if I could unlock this for her without having to pay money for it. (She won it in a competition that she only entered because her iPhone died recently - but the Live WT19i is locked to the wrong network)

Well actually for a sim unlock at this moment you will need to pay for, there's no way to unlock the sim for free. Unlocking the bootloader it's a different matter than the sim. I didn't mention it because you were asking about the boot loader sorry.
And I stupidly assumed unlocking the bootloader would allow me to unlock the SIM lock/branding.
Thanks again for the help, I'll just tell her she has to pony up the dough if she wants to use it on her network.

[Question]Unlocking Bootloader & TurboSIM

Hey folks, I've been nugging around the bootloader unlocking problem, since I own a Neo V which is locked, and the service menu in the phone says that the Bootloader cannot be unlocked. So I've read through some threads about this, and I wondered upon the idea, if I unlock my SIM lock(probably with TurboSIM, since thats the cheapest solution), would that enable me to unlock my bootloader, and start the real modifying of my phone?
What do you guys think? Worth's a try?

Both are unrelated but often confused. Unlocking for a different cellular network and unlocking bootloader are completely different sadly.

unlocking h901 t mobile?

yeah, it uses the device unlock app.no it says i'm not eligible for unlock.the seller who sold it to me even requested tmo and was denied.tried rooting and messing with system files now it says can't connect to remote server even after reflashing stock using LGUP.Tried using the f600l rom port, no you can't get the sim unlock prompt to pop up.tried blisspop and resurrection roms, they do prompt for a sim code but the codes do not work it says 255 retries remaining<<<something not right there.I do have the right unlock codes, just get them from an unlocking site or ebay.Speaking of unlocking sites, they want 60usd+ to unlock the tmo variant WTF!! Also if you try to get into the sim unlock menu using stock rom (dial 2945#*901#) it just says device permanently locked for everything.Now if there was a way to get a stock rom or port from say at&t variant which has the sim unlock prompt it just might work.
The closest i've got to unlocking this thing i the actual network unlock screen that comes after you flash the stock firmwire through LGUP. it said 0/30 attempts or something for a brief second or two the first boot after reflashing and then it restarts before you can even do anything into os never to be seen again unless you reflash it again but again you will only see it for a second and its gone again.I wonder if there is a way to keep that screen on so you can attempt to unlock it via code.
Also I'm pretty sure the device unlock app is just there to check prerequisites of your t mo account.In reality it does unlock the same way as other phones.probably just applies unlock code from tmo database once it checks you've met the criteria for unlock.
t-mo has really locked these down .
So has anyone been able to successfully unlock this phone without the tmo app? or have a cheaper service to unlock this thing ? Else im stuck with a paperweight.

Unlockable Bootloader - options?

After rooting my Z2 and backing up the TA partition, I've discovered that the bootloader is not unlockable (it's a Vodafone branded device).
Is there a nefarious way in which to bypass this? I understand that the whole point is to keep it locked, but it's an old enough device so I may have missed where it's possible.
Otherwise what are my options for an up-to-date custom rom? As indicated, I've already achieved root and have TWRP installed. I tried flashing Lineage via recovery but got an E: unknown command [log] error.
I'm in the same boat unfortunately. I bought a used phone that had Vodafone UK. It was marked as SIM-unlocked, and that seems to be true; the service info doesn't show any filled checkmarks nor counters in SIM lock information. However, bootloader seems to be locked forever - flashtool reports "Bootloader status : NOT_ROOTABLE" and phone's service menus also say that rooting status is "bootloader unlock allowed: no".
I wasn't even aware there are Sony phones that are not SIM-locked but are still boot-locked without any way to unlock.
I would really want to upgrade from Android 6 to at least 7 because there are some specific apps that work only from A7. Wondering if there is any custom ROM that would run on stock A6 kernel but with everything else from A7? It should be possible to install such a ROM even on a bootlocked device, right?
Since posting I've discovered some answers. The bad news is that, no, custom ROMs are limited without an unlocked bootloader.
The potentially good news is that you can pay for an aftermarket SIM unlock, which has the side effect of also allowing the bootloader to be unlocked.
I've not tried it myself, but do a search for "Sony cable unlock credits" for some leads.
Yea I also am stumbling upon this same news, in my city there are some shady areas so I will ask around and see if anyone is capable of doing it and will let you know.
So far my phone has bootloader locked, sim locked with 3 attempts left so I will work on unlocking those and then rooting the phone and digging deep after
Lets cross our fingers that somethings comes up
So far online , I find only old videos and outdated information, websites down and nothing else.
One thing is for sure, if your bootloader can be unlocked, you just go to sony official website and follow their instructions and its free and easy,
But if it says ""bootloader unlock allowed: no" then...lets see what can we do.
Hey I am willing to pay, why not if its going to unlock the bootloader 100%
