There is a rule which is very senseless... you have to write 10 Posts... and if you write something what you are interested in, you get one of these answers:

try the forum search
this was many times discussed
yeah I've searched for, and I've found threads about this topic, but I'm not allowed to ask in this forum...

Help needed :(

Dear XDA users!
I got my T-mobile branded Xperia Z C6603 with 10.3.1.A.2.67 firmware.
I want to root it, i read a lot tutorials, but i don't understood what i have to do.
When I dial the service nuber, in the configuration the rooting status is: Bootloader unlock allowed: NO.
So i don't know how to unlock and root it.
Please help me.
Thanks
You cannot unlock the bootloader, but you should be able to root your xz with kingo android

Don't think you should recommend Kingo Root to users.
The program tries to contact servers in China for the root, for no reason and the developer of the application refuses to answer any questions regarding it.
It WAS discussed In this thread http://forum.xda-developers.com/showthread.php?t=2460745& 'til a mod closed it due to lack of response from the software developer and it seems insecure

T-Mobile Jump Program

Hello, I just got my Sony Xperia Z1S a couple of weeks ago and I'm on T-Mobile's Jump Program. I understand how the program works but I'm wondering if I root the phone and put a custom recovery on it will they say I can't jump to a new device when I'm eligible?

They can easy find out if you are rooted or not by seeing the boot loader its binary change for good if you root.
Only some devices have binary resetter.
so think and take you next step.
Press thanks if I helped you.
That is incorrect.
The boot loader on a Z1s can not be unlocked.
You can always unroot Xperia devices by flashing a stock ftf and no sign of routing is left.

without unlocking boot loader how can we root ?
You follow the one of the several guides in the development section.
Unlocking the bootloader is not the only way to root and since a lot of Xperia devices can not unlock the boot there are lots of ways to root with out touching the boot loader

Unlocked bootloader is always rootable.
Locked on other hand is sometimes HARD to root.
So if you can't root locked bl, it's easier to make tutorial to root with unlocked.
Since z1s can't unlock bl, it's mean it is locked, he rooted that way.
If he unroot, or flash stock rom, no trace of root is left behind.

That is only one way to root, and always works, if you are allowed to unlock the boot
But it is not often the only way or the best way or even possible (as some devices can not unlock the boot)

Yup. I am rooted but my bootloader is still locked. The only other device I had where I was rooted but my bootloader locked down tight was my Motorola Droid X. But still was able to flash custom Roms through Bootstrap recovery.

But its always, to me, nice to have the boot loader unlocked because you can do a lot more in the hacking sense with no worries. All of my other devices that have the BL unlocked are all easy to save if you some how bricked it. No need for rsd lite / sbf your Moto device. Plus all of my devices where I unlocked the BL, I had long after the warranty expired.

Root p9 EVA L-19

Hello guys is there anyway to root my devices without unlocking bootloader?
Sent from my EVA-L19 using XDA-Developers mobile app
Nope, thats the first pre-req to install a CWM which helps you get root access.
I was a Sony xperia z1 user and on it i got root acces with a locked bootloader.
So, all Huawei phones can be rooted only by unlocking the bootloader?
