[Q] How to unlock the unlockable Xperia Tablet Z !? - Xperia Tablet Z Q&A, Help & Troubleshooting

So I dug out my old Xperia tablet and wanted to install some custom roms. To my surprise I cannot...
My bootloader is unlockable.
Its about 5 years after release of this tablet and I just don't acknowledge the fact that such a device is in ANY way unlockable.
There has to be a way of unlocking this crappy bootloader.
Would going to provider do any good? It's a few years after the warranty time so why not let me actualy do whatever I want with this device ?
Like someone else said in another thread - it's maddening and unthinkable...

[Q] General stuff about xperia rooting etc

Hello, I have just preordered my Xperia active from a local salesperson, but from what i see in the development threads, its nothing like HTC phones when it comes to rooting.
In HTC phones all you had to do is, unlock the bootloader with an update.zip file, root it, and then you're free to do whatever you wanna do from CWM.
I really havent understood how the procedure goes in Xperia phones, nor is there a comprehensive guide towards rooting the phone.
So could someone explain in simple steps what i need to do to root the phone? Or even is it worth rooting it since its so new and the development is more or less... inexistant? The only real custom rom I see so far for the mini mini pro and active is the FXP one which is in beta stages AFAIK.
Also about unlocking the bootloader. Losing DRM and TrackID is what makes them know that you have unlocked it therefore you lose your warranty?
Please enlighten me

For the active... there doesn't appear to be much, but if you have 'OCD' like me and like the absolute control... it's worth it. But to each his/her own preferences
Once you unlock, DRM is permanently gone, no more TrackID.
I'm not sure about warranty regulations but there is a way to re-lock the boot loader:

Hope this helps.
EDIT There's also a way to unlock the bootloader and not lose DRM
http://forum.xda-developers.com/showthread.php?t=1285285
But there's no current way to relock it if you use that route.
Thanks a lot for your detailed reply.
Although i still got questions regarding custom ROM's. I saw someone mentioning a insecure kernel, and using it before flashing a new ROM. Kernels in HTC devices are simply there for you to find out which one is best for your country and ROM. Is it the other way around here?
Yes i do want the best out of my device, but voiding warranty for something that isnt yet "ready".... It kinda puts me off.
hi dumraden,
The days with simply zip unlocking are gone either on HTC. The HTC Desire S of a friend of mine was locked. They call it S: on ..unlocked was S: off
I could not keep joking about who was so silly to convert his Desire S back to a Desire.. sorry for that
The step with the insecure kernel is to flash a stock rom where we know a method to use an exploit on it. Sony prevents unsigned firmware from beeing flashed to their devices (compare ps3 or PSP). Thus we need to make use of an exploit to get access to the device to make rooting possible. As root we are the master of desaster and can do what ever we want.
Warranty? Okay, there is a possibility to relock the bootloader in case you'll run in the case of needing warranty. Otherwise there are ways to make it that unsuable that even the support cannot wake it up thus find no real reason for the error.
This is not an FXP ROM, it is cyanogenmod ported by Team freeXperia and mainly released by FXP. It is almost ready. The smartkeyboard and camera did not work on my selfcompiled one on friday. FXP claimed camera would work. Could be my fault.. who cares. They'll get it fixed.. I think soon.
Yea i am a prior HTC user, have my Desire Z getting fixed as we talk ( i hope so at least ).
So basically the insecure kernel works as an exploit for us to install custom roms on the phones. Cool thanks for the heads up.
Wasnt FXP working with cyanogen to build a kernel from scratch in order for us not to have to go through the hassle of using a modded stock kernel for the Custom ROM's? As far as i can tell this is a breakthrough for Xperia phones since we will be able to have an AOSP base in order to build from there up. Right?
I have the same rooting problem. I use superOnClick and gingerbreak but didn't work.
I'm new to android so that keep searching and reading xda..
Then I start using android sdk & fastboot and adb mode said in one of the topics, but fastboot didn't work even though bootloader is unlocked.
I'm confused, waiting for help

[Q] Verizon Z2 Root and Unlock?

Hello Everyone i am now a proud owner of the sony z2 tab with verizon and i know how verizon is when it comes to unlocks and rooting but i want to know if there is any development going on to root or unlock the bootloader for the verizon version of the z2 tab cause i pretty sure the unlocks already made may not work on the verizon lte version
I personally want to say thank you to all the devs who work on these devices cause through your hard earned work it makes my experience on all my devices exciting and very good so THANK YOU all and to all testers as well
I apologize for reposting accidentally posted in General if mod sees it im sorry for the mistake
U can root with towelroot and have a custom recovery, but the boot loader is still locked so no cm and no roms yet. Sure someone is working on something for the boot loader or roms, but no news yet. Look for threads with for locked boot loader.

question about Verizon Note 2 Bootloader

Figured I would post this and ask..
Is there anyway to check on here or an outside site if the bootloader has been unlocked and a stable version of Cyan is available..?
last time I asked about issues with loading cyanogenmod onto my Verizon note 2 4.4.2
As I said on the previous thread you made earlier this month, root is available for 4.4.2 but no bootloader unlock method.
I was asking more along the lines of where to check if the loader has been unlocked...
is there somewhere on here/external site ..?

Honestly I've been in the game for years and XDA is one of the best sites for your info, as most, if not all? of the devs are members and are active on here. But as much as we want it I doubt the bootloader will get unlocked as it is a old phone and will not be getting lollipop, however if you don't mind to pay a bit, mobiletechvideos.com can downgrade your BL to 4.1 so you can root/rom again but it's 2-4 days turnaround and $75.00.

Does unlocking bootloader brick a tablet?

Hello
My friend is gonna unlocking his Sony Xperia Z2 tablet SGP511 but he is very afraid that unlocking a bootloader bricks his tablet because his tablet is 2 months old. he don't use any Sony apps so he don't care if he lose his DRM key. i really need your real answer and a explanation about why it can brick or why it can't brick. thank you
bump. i need answer
It can brick the tablet, but it does not have to. Otherwise no one would do it...
He just needs to do it properly
If he follows the instructions properly then it can only brick if there is a hardware fault.
OTOH what he does with the unlocked bootloader afterwards ROFL... plenty of brick-able things you can flash!!!!!
If he's that much of a n00b that he has to ask, I would advise him to stick with stock. if he wants to mess around with ROMs etc. get a Nexus, that's what they're for.
Any other Android OEM (except for Xiaomi I believe) unlocking bootloader and custom ROMs involve extra complications and / or loss of functionality / loss of warranty.

Z3v Marshmallow AOSP

Recently I got an email from Sony about AOSP Marshmallow being available on the Xperia line. I was wondering if it's possible to build and flash my Z3v with Sony's AOSP. In theory as long as I have an unlocked bootloader it should work, right?
Thanks,
Phillip

Terrible theory, your bootloader is far from unlocked. You will destroy your device attempting that. Since none of that exists for our device yet you will have to wait. And to tell you the honest truth this device is over a year old, hardly anyone competent in Android even owns it. I would be genuinely surprised if we ever see marshmallow, let alone an unlocked bootloader. Everyone should know the difference and understand these terms inside and out before flashing anything if you expect to have a successful experience.
