[Q] xperia z kernel installing

hi you all, i have an xperia z rooted with doomlord toolkit v18, and an dual recovery 2.7.14 installed. i have successfully flashed and backed up the eXsitenZ 5.0.0 rom (by niaboc79 Great success by the way). so now iwant to install the famous doomkernel and i have a few question because the information i got from around the net is confusing.
so here are my questions:
1. Is installing the eXsitenZ means i have unlocked my BOOTLOADER?
2. do i have to unlock my bootloader in order to install DOOMKERNEL?
3. is unlocking the bootloader is irreversible?
thanks ahead for any kind of help, greetings perfect9stranger.

1. No, you only have to unlock your bootloader for a custom kernel. There is also written that the existenz is for LB(locked bootloader) and UB(unlocked bootloader).
2. Yes.
3. Before you unlock bootloader, it would be good to make a TA backup. There are DRM-keys included. If you loose them, you loose warranty.
Because once you have unlocked your bootloader, without a backup of the TA, you will never get the DRM-keys back.
So only relocking the bootloader is not always enough.
The TA includes unique data and that is the reason why you can't restore the backup of an other phone. If you do it you will hardbrick your phone.

no, its not possible. you would be stuck on boot since the bootloader is locked and wont allow the phone to boot with root access on.

Hi, any news on this topic? I'd like to root my phone without unlocking the bootloader (just so I can keep the warranty)

still not possible

You can re-lock your bootloader with SRK Tool before you have to send your phone for service.

Can i Flash Custom Recovery TWRP Without unlock Bootloader ?

Hi guys ,,
I have P10 Lite and I went ask Can I Flash Custom Recovery "TWRP" Without unlock Bootloader ?
Thanxs

Without unlocked BL you are not able to flash anything. Although I do not know exactly if this is true but the allow unlocking option in develeoper settings should be the answer..

This could be possible. Flash them and turn on the unlock option. Then you should be able to flash whatever you want to.

Relocking Bootloader?

Hello everyone, I unlocked my bootloader for root purposes and backed up my TA image.
Restoring TA cures the camera problems, but my attest keys are lost... (what are they for?)
Anyway is there a way now to get back to stock and relock the bootloader?

Mipad 4 plus soft bricked with bootloader unlocked state. Cant revive . Please tell me what to do. (In normal condition when i reboot the unlock image was shown and I thought bootloader has been unlocked) i did not check before flashing. While flashing global rom it is shown that bootloader locked out. What to do now? Is there any way out ? Please help.
