[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

Check out this thread:
SE Bootloader Unlocking v1.6 by quangnhut123
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.

do I need to re-unlock my device after returning to stock via flashtool?

I meant following the unlock instructions from the Sony website.
I want to reinstall cyanogenmod/aokp and use CWM that cm came with this time!
Thanks!
No. Once you unlock your bootloader, it doesn't relock until you do the process.

Q: bootloader relock(769)

So I unlocked it for the 769..flashed cm sucessfully
...then went to stock with flashing a kdz. Seems boot loader is relocked on stock but I read somewhere its only temporary, can't remember where..so how do I unlock it again? Without the whole kdz 20b europe process again.. I know its locked cause I got security error when flashing recovery/ROM..got it back with fastboot
Also hidden menu says locked...
However sw upgrade mode still says boot loader status unlocked..

I envy you so much, why in the world would you go through all of that simply to relock?

Hi matthewstice, I think that your bootloader is only apparently locked, you need JB roms (or at least load JB u-boot and x-loader with fastboot)... , I'm not sure, but I read something about it here, just don't remember the link.
Cheers. Good luck.

The idea wasn't to relock the boot loader..
Its unlocked on sw upgrade mode still when I flash new kdz....it says.. Boot loader status unlocked..
Confusing I know
Unlocking the boot loader took me 5 minutes..
"All that trouble" u say?

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
