Hey friends, I have a Sony Xperia Z device. First, i unlocked it's bootloader, then i re-locked it using the TA-partition backup. But now I want to RE-UNLOCK the bootloader to install the new Android 5.0 and I don't know how to do it. Do i need to do it in the normal way?

Hello developers, I am considering to root my new Xperia Z1, but I don't want to unlock the boot loader. I was just wondering if I use vroot to root the Z1 but without unlocking the boot loader, will it avoid my Sony original warranty? Thanks. My firmware is 14.1.G.2.257

Well it may or it may not. You can just easily reflash stock firmware and root will be gone anyway. Done it once and they never suspected anything

In almost all cases you can restore your phone back to it's original state so they will never know, in the case when your phone is so bad that you can't restore it back with PC Companion or flashtool then you are still good because the service place will not be able to tell either, because your phone will not be booting at all .
my Z1 is on lastest stock kitkat firmware 14.3.A.0.757
does i need downgrade,root and backup TA before unlock bootloader?
or i can unlock bootloader directly and flash doomlord kernel to install rooted rom?
thx for your help

Its your choice
If you want to backup your ta you need to downgrade
If you are not bothered, just unlock

if losing Warranty is not a problem to You then Yes, it's the quickest way. Doing this you will be unable to do a Backup TA so your DRM keys will be lost forever with the warranty.

I unlocked on 4.3 and Camera, Track ID working. X-Reality turn On and Off but I never, even when I was stock, saw any difference. So if you want unlock on 4.3 (FW .136) it's ok.
So I want to unlock my phone Bootloader and install a fresh AOSP 4.4
Mine current android version is 4.3 Jellybean ( 9.2.A.1.199) and on the sony bootloader unlock site when I insert the dial number it says "Root status ...... Allowed "
I rooted it today ( havent installed recovery buy I can do it later)
My questions :
Can my phone brick while trying to unlock the bootloader?
Do I need to download the latest version or the 4.1 version of android ?
All this I'm doing 'cus my 1 year warrantly has ended today so Why not ? :good:
Don't think the bootloader unlock procedure has much risk of bricking your phone... especially if you use the official Sony Bootloader Unlock method. But you may want to read up on backing up your TA before unlocking the bootloader.

I'd also suggest backing up your TA first. It's all in here: http://forum.xda-developers.com/showthread.php?t=2292598
If you unlock your bootloader, you lose your Bravia Engine. You can get it back when you lock bootloader, but only if you restore your TA. If you don't have this backup, BE is most likely lost forever.

I've done backing up my TA keys ( done the dry restore to make sure )
So Now I only need to unlock my bootloader ?
Still one question :
Can I use my current version of android 4.3
EDIT : Unlocked the bootloader , put rom , gapps , wipped WORKING AS A CHARM
Thanks for the help !
And if I would like to restore to stock do I need to relock the bootloader ?

Nice!
If you want to get your phone back to stock, just flash a stock FTF. Flashtool does not require the bootloader to be relocked for that.
Unless you mean "stock" for warranty purposes, or selling the phone... then I guess I'd say yes to relocking the bootloader, after flashing a stock FTF (and also restoring the TA, of course)
Thanks 4 The Info )))

sony do not have the data of the phones unlocked unofficially. so if you brick your phone you can relock the bootloader with TA partition and DRM keys so that you can flash stock firmware using flashtool ( or repair using PCC ). Then you can visit service center
Hello all! Im new in xda forum, so i will be greatefull if you help me with my Sony Z1 phone. I have Z1 c903 on android 5.0.2., and I was mad on sony becouse they didnt make update to 5.1, so i was looking on forum how to root and install some custom rom and make my phone updated. So i find on some thread that i should unlock bootloader, and i followed instructions and unlocked it, but without making some backup or anything else. So i have seen that there is official update for sony and i want to get back to lock bootloader. But when i enter flashtool and enter "blu" i click on relock bootloader, and start phone type *#*#service#*#* it say that my bootloader is still unlocked. How should i get back to locked bootloader or make official update to 5.1. Please make it more clear becouse i am pretty noob for android development and rest. Also i want to add that i have not rooted my phone or install some custom rom or other, i just have unlock bootloader and thats all. Could i get back my "DRM keys" and could i get back my ofiicial android. Thanks in advance.

oh dear, you lost your drm keys.... thats not good....all sony own camera features (bionz, noise reduction...) are lost now. So without your drm keys, you dont get an advantage of locking bl again. SImply flash official sony 5.1.1 and here you are
Tutorial?
