Does anybody know if there is a way to relock the bootloader on the ZR?
Have unlocked the bootloader but realized that I don't need it unlocked.

AFAIK, you need to backup using Backup TA first before unlocking. Then you can restore everything using it again later.
Unfortunately I was stupid enough to not do that, so right now I have a backup with an unlock bootloader.

Try this?
1. Download and install Flashtool
2. Connect phone in Flash-mode (phone shut down, volume down + power)
3. Press the BLU button
4. Press the relock option
5. Put a stock .ftf firmware in the Flashtool firmwares folder
6. Flash the firmware
Let me know if this works.

When ressing the blu button in flash mode flashtool just wanted to unlock.
When going into bootloader it relocked just fine!
Thanks!
When you unlocked your bootloader without first running Backup-TA you lost your DRM keys though, so Bravia Engine for example is gone for ever. There is no way to recover this and you cannot flash a backup from another phone as it will brick your device.
http://forum.xda-developers.com/showthread.php?t=2153261
the problem is theres a file missing in flashtool folders for xperia zr:
loader.sin.
it exists in the xperia Z folder, you can try and copy it, but i'm afraid it might hard brick the device, i don't want to try it without knowing first...
Even if you recover your TA the DRM keys still are gone!! but still there is nothing absolute and drm can be restored without having them (there was a method on Xperia S and Xperia P which worked great!)
I relocked my bootloader by flastool first it said that loader sin wasn't found in c550x folder so I took the loader sin from stock .244 kernel and it worked

I've done the same! Just unlocked the bootloader without thinking at all. So are you managed to relock it eventually? I'm seeking the way to relock it desperately!

Thanks a bunch I was able to relock my bootloader:laugh:
Before i unlocked the bootloader and rooted the phone without problem, when the update 4.3 was arriving i decided to relock the bootloader and flash a jelly bean firmware for update it by pc companion. Now i decided to unlock again to install omnirom, i flashed 4.1.2 firmware and then i tried to unlock bootlader but when the process is finished and i turned on the phone it doesn't boot, the animation is blocked and the phone will restart. So i flashed again 4.1.2 firmware, it turned on and in the service info --> configuration the phone said that the bootlader is unlocked, at this point i tried to root but i received lines of "impossible" on the terminal, i was be able to do all this one month ago but now i can't understand where is the problem. Someone have any idea??
Thanks in advance and sorry for my english

Or it says

You have to check on flashtool to wipe everything for a factory reset. In your case I would flash a stock rom, unlock the bootloader via flashtool and then install a custom rom

How do you try to root? Do you want to install a custom rom? If you want to install a custom rom do the following:
1. flash the kernel from the custom rom
2. boot into that kernel and flash the custom rom zip file
3. wipe cache and dalvik
4. flash supersu zip file
If you want to stay stock but with root and are on 4.3:
1. flash the kernel of a custom rom
2. boot into that kernel and flash supersu zip file
3.reflash the stock kernel (excule everything else)

Yes i want to install a custom rom, i tried to root the phone using doomlord easy rooting toolkit to intall later the cwm, i know that if i do like you say i can install custom rom more fast, in less passages, but before i did this passages for root the phone and it worked but now after i unlock bootloader the phone doesn't start and i must flash again a stock rom with flashtool to make it work again, i know that then if i see in the phone i have the same the bootloader unlock but this isn't normal and after this new problem also the root doesnt' work
I hope that you can understand what i mean also if my english is bad
Yes maybe i can stay on 4.3 stock rom but to flash a custom kernel i must unlock the bootloader and we arrive at the same point of before, i'm not sure that the unlock works well

So on 4.1.2 easy rooting doesn't work? Umm, are you sure you're following it step by step? (If I remember correctly there are 2 ways, one for locked and one for unlocked bootloader, you have to use the one for unlocked bootloader)

If I find any solution I'll let you know.
Can please someone confirm this will work?
1. Downgrade to JB 4.2.2 14.1.G.1.534
2. Install locked dualrecovery 2.7.97 BETA
3. Flash KK 4.4.0 14.3.A.0.681
4. Flash with CWM superSU
I am asking because I read somewhere the following method:
1. Flash KK 4.4.0
2. Unlock bootloader
3. Install CWM thru a very complicated procedure that requires fastboot
4. Flash with CWM supeSU
Now, my question is: since I could install dualrecovery for unlocked bootloader, to avoid ulocking bootloader, why not downgrade, flash dualrecovery, upgrade and flash su?
Can please someone confirm this will work?
1. Downgrade to JB 4.2.2 14.1.G.1.534 (and root it)
1.2 (Backup TA Partition !Important, for the future)
2. Install locked dualrecovery 2.7.97 BETA
3. Flash KK 4.4.0 14.3.A.0.681 (via recovery)
4. Flash with CWM superSU

If you're not going to unlock your bootloader then do not do it. you can also backit up when you're running kitkat with root.
But what's the harm? )

I was hoping it would be less complicated...
I still do not understand why I have to root after downgrading...
After all, all I need is a custom recovery to flash superSU, and according to the guide all I need to install a dual recovery is. 534, no need to root it or to unlock it, according to the guide.
So if I do not want to unlock device and I do not care backing up TA, the following should suffice
1. Downgrade to. 534 with flashtool
2. Install dual recovery for unlocked phones
3. Upgrade to kitkat with flashtool using an official ftf
4. Flash superSU with cwm

Just try it, you seem to be wanting extremely specific instructions and questioning everything you are told. Please try following them them asking for help as you go along, you never know, it might just work for you....
There is no need to unlock the bootloader if you downgrade, root, install recovery and flash a pre rooted rom. Please tell me which step of these instructions say "unlock the boot loader"

I guess u r rite.. so I am gonna unlock: do I loose any sony feature? (audio plus, x reality, ...)
Also, since I do not have a custom recovery, I guess I will have to flash the kernel via fastboot, whi h will give me the ustom recovery, then flash superSU with the recovery

I know I know... all I wanted to say is: eithef I stay on KK and unlo k the bootloader to root, or I do not unlock but have to downgrade etc.
Unlocking at this point seems easier, safer and faster, as I will keep my current rom which works fine
I will do a backup with sony toll and restore afterwards
But once you downgrade, root and install recovery you just flash a pre rooted 4.4 rom... The one from NUT is made from a stock ftf file with the relevant root files added to it. I don't see the issue.
As for unlocking, read the information on the sony website about it. You have to unlock using that site anyway. You will lose warranty and drm keys. However, to be able to lock again you need to back up your TA partition otherwise you lose the drm keys forever. Now to do that you must have root, so you are going to have to downgrade and root anyway

Hmm, don't worry about bootloader.
Let's keep it unlocked, which will help you in many cases.
