Xperia Tablet Z 4G locked on EE with a locked bootloader - Xperia Tablet Z Q&A, Help & Troubleshooting

Hi guys, first off, I'd like to apologise if this is not the right place for this thread- feel free to move it to the right place if so!
Secondly, I'd like to ask if there's a method for unlocking a bootloader that is locked... do I need to unlock the tablet from the EE carrier first? Or is there another method of doing so?
I tried to root the device for hours on end and nothing managed to work at all!
Any help at all would be appreciated!
Thank you,
Amro

if you have an operator market device, 99% you will not be able to unlock your bootloader.
You can look in Service Menu if your device bootloader is unlockable.
But even if it is not, you can root your device easily, just look for instructions on XDA.
The only thing you won't be able to do with unlockable bootloader is install custom (e.g. CM, FXP) firmwares on your device.

well, you should know that finding an unofficial way of unlocking the bootloader takes a huge amount time and work.
i donĀ“t think that the devs will look for an other way to unlock the bootloader while there is an official way.

[Q] Can you help this newbie in Android world? simply questions.

Hello my friends. I had an iPhone 4 and I just bought my Xperia Z2 5 days ago.
During these 5 days I am here in this amazing forum reading a lot about Android development. So lets go to my questions.
So. If i wanna have all access into my phone...
1. I must root it...
2. then make a TA partition backup to save DRM keys and not lose warranty...
3. If i want to change ROM and Kernel i can unlock bootloader after these steps.
is it correct?
And if one day I am tired of all this and i want to Clean restore my phone.
It means i want Stock rom, Stock kernel, non-rooted and locked bootloader, is it possible? if so, in what thread it explain what to do?
My Xperia Z2 is from Brazil model is D6543 and firmware is 17.1.A.2.55
thank you very much, I will probably root my phone soon after answers here. :good:

Yes all this is correct.
I believe your model number is D6503?
Some ROMs can be flashed on a locked bootloader as well.
Use this for rooting on locked bootloader:

I can't find the tool for TA Backup yet so I recommend you check the Cross-Device development sub forum.

Man, I am really thankful for your answer. But no, my model is D6543. It sells in brazil that comes with digital TV. Will it be a problem for me?

Ah I see that the only difference is a few LTE bands. Nothing else. I would recommend you ask in a ROM thread if the model number is supported or not before flashing a ROM

Help with bootloader

Hi, I'm pretty new to the android scene, I've looked for a few days if there is a possible way to unlock bootloader on an Xperia M4 Aqua 2306, the issue is my phone has Bootloader unlock allowed = No and didn't actually find if there is an actual way to do this.
Found a few threads talking about how to unlock the bootloader but it seems from some posts that it's not possible to unlock, I was wondering if anyone could help me figure it if there is any possibility to unlock since my phone is quite slow and would love to breath some life to it, any help would be greatly appreciated!

the onli way i was able to root my 2306 was to downgrade with flashtool to lolipop the vertion 26.1.A.1.112 ...the onli one old enough to root with kingroot the onli app i found to root lolipop ....but then none of the tutorial i read got me back to the last update without loosing root and aving to deal with the 100 of preinstalled app .....tryed to let it at lolipop but the phone is now extremly sloooooow
was able to get to recovery but then after looking at all custom rom .....they all need to be install with fastboot and they all stated that you need unlock bootloader so i stop trying the phone is not realy worth it anyway

Custom Rom with Locked BL?

Hi, I have had a look around and searched for this answer but cannot find a definitive answer. Is it possible to intall any custom roms if my BL is unlockable? I have checked and unfortunately I cannot unlock it on my phone (If anyone knows a way, I'd appreciate it).
I can't seem to see any mention of BL in individual rom posts but assume they need it as they use TWRP to install the roms and TWRP as far as I know needs an unlocked BL.
Thanks
There's an official website for unlocking bootloader: https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/
If needed further help regarding custom ROMs, feel free to leave me a reply.

Sorry to hear that but if your bootloader is not unlockable you are stuck with stock. AFAIK there are no ROM for BL and I don't think any will be created due to the old age of this model and the support of the Sony Open Source Project
