Updating normally will brick the phone with an unlocked bootloader. You would need to re-lock it or flash the ROM manually.

Got root on latest L 5.1.1 Z2D6503 with this method

Hii
I just got my Z2 rooted with this method
I just followed the steps
http://forum.xda-developers.com/xperia-z2/general/guide-how-to-root-xperia-z2-android-5-1-t3253878
Just one question
My bootloader sayz unlock not allowed...
Can I now flash TWRP or not?
Or is it just that I can not flash kernels??
I dont understand what is diffrent with bootloader locked and unlocked
Mine as I have read is locked forever so I dont want to brick my device or something...
Some advice about such bootloaders and what I can NOT DO would help me to understand
Thanks in advance
EDIT 01:
I just have followed the link in that post where I have rooted the phone
And just got TWRP installed as my recovery
So just to let you guys know evan dual recovery works fine with L5.1.1.
Just to say I have LockedBootloader
So guys please advice me for further
What restrictions do I have with the LB in diffrence to Unlocked BL
Can I do exact the same flashing of things like they on unlocked BL or not?
What should I be carefull about
Please guy give some info

1- With locked bootloader
you can only flash sony stock based roms (you can flash miui rom as there is a version with sony stock base).
you cannot flash cyanogenmod or custom kernels and any other rom.not based on stock sony.
2- with Unlocked bootloader
You can flash any custom rom or kernel for xperia z2 including cyanogenmod.
But you will LOOSE your DRM keys if you unlock your bootloader which will degrade the camera quality and xreality engine...

You cant accidentally unlock your BL and if it says it cant be unlocked Im afraid it is locked forever. There is no any way to unlock it AFAIK. If you have root, which it looks like you do, you can install TWRP by downloading an app TWRP manager from the plat store, give it root permission and in Install section find your variant of Z2 and let it doo its thing. It will automatically flash recovery.img and reboot and thats it.
Now you can flash all [UB] as unlocked bootloader marked roms, but no custom kernels and AOSP ROMs.
In my experience, if you try to flash something for LB it will just produce an error and you can reboot your device normally without any changes.

Thanks guys !!!
No its all clear to me

[Help Please] Unlocking my bootloader in Marshmallow. (ZE550KL)

Hello, i have ZE550KL and i need to unlock my devices bootloader.
I know how to unlock bootloader in my phone but in the Zenfone 2 Laser if you are in Marshmallow it says "Unlock Device App stopped".
There isnt problem in Lollipop, if you use "Unlock Device App" it succesfully unlocks bootloader.
But i want to unlock bootloader in Marshmallow, but how?
Thanks. Greetings from Turkey.

Just download the pre rooted Version matching your SKU from here and flash it, you are done.

I dont need root. I need flashing a TWRP and a rom. Why i flash Prerooted?

Unlock app current supporting LP version, and wait for new Unlock app for MM version. If you cant wait for it, just downgrade to LP and unlock bootloader. Once unlocked means, your device bootloader cannot lock back. Now if you want to go back to MM, then just upgrade it. In MM your bootloader will be unlocked only. If you want to see how i did this, visit my youtube channel here
