if you have custom kernel you first must flash stock kernel and then with s1tool chose relock/restore (phone in flashmode) option

if you want to upgrade your ROM you must unlock your BL. So you can flash the kernel or alfs then flash the ROM!
I think bootloader is same thing like BIOS in computer..
so we can change everything inside the phone system

Q: What is bootloader?
A: In simple terms, a bootloader is the code that runs on a device before the operating system starts up. This low-level code contains the instructions that tell a device how to start up and find the system kernel. Every time your phone starts up, that bootloader code is telling your device what to do in order to get you to the home screen. As you can imagine, this process is vitally important. As such, manufacturers often use security measures to keep you from tampering with the bootloader.

note : i read many thinks about this but i am still don't know
Hello,
First of all you need to root your X8, download Flashtool, install it, run it, install drivers from folder and go to Applications>Unknown Sources(check)>Development>USB Debugging after that open Flashtool and make sure your phone is recognized by the program.
For custom kernel you need unlocked bootloader, for this better search in forums. It will be a pretty long story to explain you here. There are some guides.
There you go: http://forum.xda-developers.com/showthread.php?t=2043491

Check your manufacture date under battery, if it's below 11w29 then you can unlock bootloader but if it is not DON'T EVEN TRY !
(I hardbricked my xperia once)
oh **** my data : 10W45 ... F*** i can't unlock bootloader

Fastboot issues,bootloader (un)locked?

So I've unlocked the bootloader on my xperia Z the official way. Entered the unlock key and it was successful.
However, if I try to write a recovery in fastboot I get the error : Remote: not allowed.
I have made sure I have the correct drivers and all but it still doesn't work. Even tried unlocking it again with a second unlock key.
How can I fix this?
bump, still no cure found
Any help would be appreciated
Try to boot in recovery does that work?

Yeah that's what I thought, but my bootloader is unlockable and I've done it the official way, twice!
How can I properly unlock it?

dial : *#*#7378423#*#* got to "service info" then to "configuration"
at the last line is it
bootloader unlocked : yes
or
bootloader unlock allowed : yes ( or something like that )

that only means that it's allowed but it won't say if it's locked or unlocked

not only allowed or not
if you have locked bootloader it says it is allowed
if you have unlocked bootloader it says that your bootloader is unlocked
you can check your bootloader by this way , cause your error determines that u have lockbootloader

It's not really unlocked.
Use flashtool, click the blu option and you can properly unlock the bootloader.

Unlock bootloader without losing DRM keys
Hey guys
I have a similar problem. I want to flash DoomLord's custom kernel but the command is not allowed. I found out bootloader unlock allowed does not mean it is unlocked yet, so that is the problem why it is not allowed. However, I do want to backup my DRM keys first. Is this possible? My phone was rooted before I flashed 4.3, so it is not rooted anymore.
Oh I have a Xperia Z 4.3 c6603 flashed with the ftf supplied by doomlord.

u welcome!
just checked the screenshot says that BL unlock allowed: status YES which define that ur BL (bootloader) is not unlocked yet!
make sure u are using the appropriate tool that works for ur device after u get the BL code from Sony, then follow the instructions in Sony where u got the information about unlocking BL
first off... do not proceed with bl unlock until you backup your TA partition cuz u might brick ur phone after the unlock is done if something goes wrong!
is it's not really recommended... u can still root it with a locked bl and enjoy ROOT privileges... FYI, unlocking bl will erase DRM keys and might affect on ur TA partition too.... so keep in mind that Bravia Engine2 along with Track ID will stop working after unlocking ur BL
TA Partition backup
http://forum.xda-developers.com/showthread.php?t=2234627
so take it on ur own risk as im advising you not going for it!
good luck

Long time ago i saw a thread that a user was telling that he wasn't able to unlock the bootloader when he has using certain ftf files. It is pretty strange actually.
Try to downgrade your phone, maybe installing kk and try again mate.
Maybe this will help if you already don't know it. Take a look here. Way old that thread but maybe still guilty.

Post #2 says you have to be on stock kernel to relock your bootloader.

Congratulations. Glad I could help. You can give me a thank if you don't mind.
What do you mean with fresh kernel? You mean stock kernel, aren't you?
