simple question: did someone send his/her xperia z1 to sony to repair something after he unlocked (and relocked, ta backup etc) this bootloader? can sony notice if the bootloader was unlocked?
If you unlocked the bootloader and didn't relock it, Sony can see the bootloader is open.
If you did TA backup and restore it for close the bootloader, Sony won't see it.

I don't think Sony saves the IMEI. It's just for create the unlock code.

Tried to flash doomkernel 0.9 http://bit.ly/12cotzD from this thread: (http://forum.xda-developers.com/showthread.php?t=2172888) in recovery mode with xperia z android 4.2.2. at first it seemed to work, but after starting my xperia z - nothing happend - black screen. no boot.
i tried it 4 times with CWM 6.0.3.2 and TWRP 2.5.0.0 (xz dual recovery) - everytime the same result. copied the zip file on sdcard0 before.
flashtools said that the phone is in flash mode. so i flashed with flashtools the 423 firmware. it just restored the kernel (i think), because the progress was much faster than flashing the phone completly. so it was no full wipe.
after that the phone worked again - but without doomkernel. dual recovery and all othere things were still there.
can anyone tell me why it´s not possible to flash the kernel with my xperia z?????????????
Do you have unlocked bootloader?

Doom kernel is only for unlocked bootloader,if you are planning to unlock it,backup your TA partition before unlocking,it will help you to restore your drm keys when needed.

A relock should be enough,
TA is only for bravia engine.

Hello XDA,
I have just purchased an Xperia Z1 and i'm loving it so far, I have just upgraded the phone to Android 4.4 OTA.
I would like to unlock the bootloader and flash a 4.4 Custom ROM, i got the phone with no warranty, so i will go through sony's official tool to unlock the bootloader.
As i will do that, do i still need to backup my TA partition? also i heard sometime ago that unlocking the bootloader through Sony's Website damages the Camera.
Is this still the case?
Thank you in advance.
Hi, you must downgrade to the 534 Firmware, then rooting and after that backup the TA Partition and after that flash an 4.4 ROM. if You finished you can unlock the Bootloader

Camera will work with unlocked Bootloader

Do i still need to do that even though i'm okay with losing my warranty? (as if i have one anyway)
Yes only when you unlock your bootloader you will lose warranty

Its your choice
If you are not bothered with the warrenty then there is no need to back up
Personally I notice no difference without the DRM keys
Can't i just unlock the bootloader through sony without backing up the TA and then using a custom rom and recovery?

yes you can
But if you ever want to use a warrenty then you will need to relock and put the TA back
If you are not bothered then there is no need to back it up

I am looking to root my Sony Xperia Z1 14.4.A.0.133.
I have previously rooted this device and many others and have experience with custom roms.
But I have found myself unable to root with a locked boot-loader as I am looking to restore the TA Partition of which I have backed up.
Please Help
Google for "newsroot" or towelroot. That can help you.
