Locked Bootloader - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Does anyone have a list of know Mobile Carriers who do not lock the bootloader to no? I purchased a z2 tablet from EE and it is set to no and I want to be able to
root my device, but it seems a bit of the luck of the draw trying to get one which allows it.
thanks

anyone?

3 UK - is it locked and branded?

Hi,
I've noticed similar thread about O2 but couldn't find anything regarding 3 UK. Is there anyone around here who got their S2 from 3 UK? If so, was it locked to 3 or network branded (the phone itself and software)?
Thanks!
Doesnt matter if it is locked, there is an app to unlock it, Chainfire made it if I remember correctly. should be in theme and apps section.
Thanks a lot stoney. Good news in case I decide to keep it.
The trouble is I want to sell the phone and wouldn't like to open the box to check if it's unlocked and that's why I was wondering if it was normally locked if it comes from 3. Not sure if the potential buyer would be happy to unlock the phone themselves using the software from the forums.
In case anyone else is interested in - my S2 was locked to 3 but it was possible to unlock it
My 3 sgs2 was not locked but is branded, I have not checked my replacement but I guess it will be the unlocked the same

[Q] SIM Unlock for st18i ?

Does anyone have any confirmed success SIM unlocking the Xperia Ray st18i ?
I've found a couple of sites that claim to be able to do it using a mixture of connecting pins with tweezers and paying for unlock software, but don't really want to pay unless I know it is 100% genuine
Or if anyone knows of a free way to SIM Unlock the st18i, that would be appreciated
Cheers

Yea thanks, they gave an unlock code which didn't work, then eventually admitted they couldn't unlock it and refunded £20 credit as an apology
Unlock shops have been unable to unlock it too
Everything I have read says you need to connect 2 contacts near the battery before plugging in USB and using software to unlock it, which explains why the carriers code didn't work
Why can't u check bootloader unlock status because of it does allowed then you can flash custom kernel and Rom which then unlock SIM lock.
Here is the instruction to check
First, you should confirm that it is
possible to unlock the boot loader of
your device by checking the service
menu. In your device, open the dialler
and enter *#*#7378423#*#* to
access the service menu. If you have
a tablet, click here to learn how
access the service menu.
2. In your device, tap Service info >
Configuration > Rooting Status . If
Bootloader unlock allowed says Yes,
then you can continue with the next
step. If it says No , or if the status is
missing, your device cannot be
unlocked.

Are you sure a Custom ROM & Kernel will SIM Unlock ?

No I guess that's not right. Sim lock and bootloader lock has nothing in common, only if the carrier locks the bootloader and makes it impossible to unlock. So I guess unlocking the bootloader won't unlock your Sim lock, but I'm not sure
Btw is your bootloader even unlockable?

Im not sure yet, I'm doing this over email with my family, the phone is going to be my Nephews birthday present if we can SIM unlock it, he's locked into a contract with a different provider and stuck with a crappy phone, so the plan was to unlock this one for him to swap over to while keeping the contract SIM

Hmm but I guess you are stuck because if your carrier says it won't work and another unlock shop tells you the same I guess you can't do anything. But of course it could be I'm wrong

Yea maybe, I was hoping someone else had this model phone and knew if any of the online unlocking services that claim to be able to do it, were actually genuine or not
Don't fancy giving out any money for a fake unlocker

I was able to Bootloader and Sim Unlock Xperia Ray ST18a(i) but it cost me $10 to do it. The Carrier could not do it. I used FastGSM. I don't know exactly HOW this process works but it does work. It involved connecting Test points which I believe temporarily open a way to insert a SIM Unlock certificate which may not be genuine due to the fact that when your carrier buys the phone from Sony or another manufacturer, they are factory locked in other words, the network lock is inserted into a secure partition. I believe the test points open up this secure partition for inserting another Certificate through the s1tool. FastGSM uses a program which when you log in, checks to see if you have credits, and once that stage passes, it downloads and inserts this certificate into the secure partition. It also unlocks the bootloader in this process allowing you to get Fastboot mode. This is what I believe, not sure if it is actually the case. However, I wasn't just merely satisfied that my Bootloader and SIM are both Unlocked. I prefer a technical explanation of what this process does and HOW it works. Ofcourse, the unlocking source are not going to tell me how they did it. But I believe they got their hands on the certificate that gets inserted once the EEPROM is temporarily unsecured using test points. I firmly believe SIM Unlocking should be free and should be available to anyone who wants to go at it. I believe the Warranty and other excuses they give such as warnings about security etc are redundant and pointless. If you look around, just the process of Rooting is daunting enough for most 95 percent of the population, so I don't think people would go around unlocking their phones even if the information was made available. Most people wouldn't even know about it.
Next time, purchase a phone that can be easily unlocked, Do some research. Although the $10 I spent unlocking is not a big deal, I personally do not ever want to pay a single dime to network unlock a device that I already own. Here we have to pay $50 to the carrier to unlock it. I would rather help people by giving them information on how to do it for free. Then they can go void their warranty if they wish. People who care about warranties are not going to bother with any of this, which begs the question, why are SIM Unlocks such a tightly guarded secret, and what can we as a community do to thwart the efforts of these Carriers to keep us locked in such a way that the device we own is deemed useless if its not on their Air.

[Q] Z2 Tablet Bootloader

Hi all,
I've been considering getting the Z2 Tablet, but (despite the current lack of major ROMs and development for it), the deal-breaker for me is having a tablet which can have the bootloader unlocked.
I wanted to ask if anyone has got/seen a Z2 Tablet which has the rooting status set to "no", or cannot unlock their bootloader? I only ask because I have the Xperia T which came SIM and Bootloader locked and I cannot install custom kernels on it and I want to be completely sure of the fact that there is no chance of this Tablet being permanently Bootloader locked.
Thanks!
Peace out,
-Galcactus.
Firstly, the tablet has only just come out in some areas and it still is not available in most of the world - and we only just got root over the weekend. So roms/development for it is right at the beginning - give it time.
As far as unlocking goes - they 'should' all be unlockable - but if you are buying from a carrier in some countries they might lock it down. I can't see why any wifi-only ones would not be unlockable and in fact I haven't heard of any not being unlockable (although as I said it is only just released so there aren't a lot out there yet)

[Q] Cracking unlock bootloader allowed : no to Yes.?

Hey,
I have recently bought an Xperia Z ultra, and when i was about to CM11 it, i found out that the boot loader unlock allowed is NO.
Now where is live, i brought the phone through and import shop. so the procedure to obtain a operator key and send to Sony is impossible.
I can access my fastboot, i have even rooted my phone, but i really want custom roms and kernels to be an option.
I know that the usual answer to this is that its impossible. But i would appreciate if we discuss it to progress on this as i have seen too many people with this issue and i think it needs a solution. I would request the admin/moderators to keep this thread alive.
Now does anyone know why is it impossible ? is it hardware or software ?
any directions or people that i can personally request to work on this ? any leads ? i am really desperate, i really cant afford to spend that much on a phone again.
is the Xposed Framework any possible solution for this ?
any ideas information is helpful......
There is no solution, or one being worked on that I know of. In one thread it has been asked and a very good hardware hacker said that even taking the back off and putting a Xperia into it's maintenance mode you cant unlock a BL for these locked devices.
Have a read of the hard brick thread for the details
there seems to be a way, just a thought.
Upon on reseaerch, i am finding out a Linux command called kexec seems to be favour here. Since it can bypass kernel and force a custom one...

Are there any developers I can call out/plead to regarding this matter?? its really frustrating to have this much of a powerful device and not play with it. I miss CM.
unlocked bootloader if it says no
I had no idea that the sony z ultra had some units that couldn't be unlocked. why would sony do this, it says being able to unlock your bootloader is important to sony. They even gave me an unlocked code from their site. I bought an factory unlocked phone, so stupid that this one here can be unlocked and that one can't. so am I stuck with a locked bootloader now? I sold my Lg because of this crap now I am dealing with it again ****

It's your carrier that has locked it (Rogers, i'm guessing?). There are only a couple of carriers that locks down the bootloader, like Rogers, O2 (i think) and another one that we're aware of.
It was bought factory unlocked from store no carrier involved which makes it even more crazy. I guess I will sell this model and get different one. Does the gpe have this stupid restriction on its model. I really like the 6.4 inch screen and don't want to go down in size. I am already going to get the nexus 6 so I definitely want a z ultra also

It's shouldn't be locked. Only a couple of carriers locks the bootloader. The GPe's bootloader is unlockable.
@BrownDog99 type *#*#7378523#*#* and check if you haven't. I don't think I've seen a factory one they is bootloader locked. What model? And from where did you buy it?
Ya i tried that it says no bootloader unlock. I bought it from a used cell store in toronto. It has a factory unlocked sticker on it, with no carrier apps installed or anything. Maybe it was a carrier phone, weird it came factory unlocked and with no carrier apps installed. I rooted it and put a dual recovery for lb and of course installed xposed. No custom kernel for me I guess. Too bad. I think it is Rogers and Bell that lock down the bootloader. I am impressed with the speed of it for a 800 snapdragon.

Sim Unlock?

Hey quick question about the mate 2. I bought one yesterday from a prepaid carrier named consumer wireless at my store for 250 thinking it would be unlocked out of the box. That wasn't the case though..so i am looking for a way to unlock it. Anyone have an insight on how i may be able to? I know on my htc one, i was able to do it after i unlocked the bootloader and ran a fastboot command. Any help would be appreciated!
I saw your other thread. I assume you got into it. So how did you unlock it? Was it just a boot loader unlock ?
