Your DRM keys are lost when you unlock your bootloader but with the Z2 nothing depends on these DRM Keys meaning that nothing is lost
The only thing that will happen when you unlock your bootloader is your warrenty/garentee is voided

[Q] Flashing Kernel in WT19i

I want to Flash custom Kernels in my phone which is a wt19i . Can someone tell me how to do that
There are many post that teach you this.
First unlock your bootloader and you can flash the boot.img or ftf with either fasrboot or flashtool

hope this helps!
It's your phone sim locked?
If it is then: do you have access to fastboot mode?? ( turn off your phone hold the volume up key and connect the phone to your computer without letting go of the key, the notification led should turn blue. That is fastboot.)
If yes then you will need to unlock your bootloader either the official way here http://unlockbootloader.sonymobile.com or the test point method here http://forum.xda-developers.com/showthread.php?t=1285285.
If you don't have access to fastboot then you will need to simunlock your phone first and as of what I know and at this moment you will need to pay for it.
Once you unlocked your bootloader you have to flash the kernel of your choice using flashtool here http://forum.xda-developers.com/showthread.php?t=1351309
You cannot enter fastboot if bootloader is locked.

well i know of people able to go into fastboot with locked bootloader the problem is when you have a sim lock and the bootloader unlock allowed: no message in the service menu then you will have to pay to unlock the sim along with the fastboot.

Bootloader

you can unlock it again but relocking the bootloader wont restore drm keys

question in unlocking the bootloader

ok so first
1. if i unlock the bootloader, what are the possible risks that can happen to my phone?
2. if such risks happen to my phone, is there anyway to fix it??
and
3. can if i relock my bootloader will networking functions work again if the network problem shows up?
Thanks for your answers
If you unplug your phone while unbricking you can get a bad brick. Nothing bad can come of it really. And yes you can relock your bootloader

Use xperia code *#*#7378423#*#* and use the menus to see if bootloader has been unlocked..if the drm keys are missing or not (which mine are still intact even after unlocking bootloader?)

No this means your bootloader is locked and you can unlock it.. If it was unlocked it would have shown
Bootloader unlocked: yes
For recovery power on your phone and when you feel the first vibrate or see the Sony logo keep pressing the volume up or down button continuously.. Then you will enter recovery..

I need to know more about these things. Can u help me pls? I enter recovery mode, its philps touch recovery.
What it the use of unlocking bootloader?
he could relocked bootloader.
Get into service menu (*#*#7378423#*#*) and navigate to Service Tests -> Security and check keys:
MARLIN [Key OK][Active]
CKB [Key OK][Active]
WIDEVINE [Key OK][Active]
If it looks like above, everything is fine with DRM keys and bootloader. This phone has XZ Dual Recovery and it doesn't require unlocked bootloader
I had checked service test
MARLIN[unknown Error][active ]
CKB[unknown Error][active ]
WIDEWINE[unknown Error][active ]

*#*#7378423#*#*

I do not know if my bootloader is locked or not?
Bring up the service menu, then go to configuration. It should say whether your bootloader is unlockable.
This is what unlocked looks like
