Is there any way to relock the bootloader on the XZ3? I tried using flashtool and fastboot commands but neither of them work.

?
Should think the answer were on the forum here someplace.
Weird if not. ?

It'd be interesting for sure because the boot screen is practically begging you to relock the boot loader.
Not possible on newer xperias like the xz2/xz3 so forget it

Relocking is not yet fully and flawlessly possible.
The current method for relocking worked for some, others posted myriads about how it screwed all up. As the level of technical proficiency of those users is unknown and not really determinable, at this time is probably safe to say, it's a) up to you to try and b) may work with a certain chance or c) it may not.

There is still a possibility that it does not work with your device (right now).
If you access the service menu and look up the "Bootloader unlocked" status it should either read "yes" (unsuccessful) or "unknown" (successful) if you have used the tool.
Also note that DRM keys are not coming back, so BE2 will still be missing after a relock.

With Flashtool beta4 you can unlock and lock it again.

Hi there.
After i unlocked* the bootloader of my phone i got stuck in a bootloop, then i had to flash the TFT all over again...
The problem is that i don't know if the phone is already with bootloader unlocked or not...
how can i check it?
I was thinking on trying to do the unlock steps again, but i'm scared of being trapped on another bootloop...
Is there a way to check if the bootloader is already unlocked?
PS: The bootloader unlock allowed is yes.
thanks you guys.
Flash doom kernel via fastboot with this command:
Fastboot flash boot boot.img
If you get an error than your bootloader is not unlocked.
You can flash back to stock kernel with flashtool,flash the kernel separately.

but if i got that error and confirm that the bootloader is locked, is there any chance to harm the phone? or need to flash the TFT again, etc etc
use flashtool to tell you
Another more easy approach .
When bootloader unlock allowed says yes and be2 is working in Album, then it is still locked and you can start the unlock steps again.
How can i use flashtool to tell me?
@DevShaft
Before i could see in a flash the bravia engine working on pictures. There was a little delay... Now i can't see it.
Probably the bootloader is unlock.
If i try to install Doom's kernel via recovery and the bootloader is LOCKED, can it do any harm? thanks guys

bootloop and u will have to use FTF to fix it.
Thanks man.
I'll wait the new firmware or android 4.2 to see it.
thanks everyone.

I unlocked my Xperia Z and in Service Mode I can see 'Bootloader unlocked: Yes'.
Now my phone is running on latest C6603 firmware and DooM Kernel.
To my surprise, BE2 still works! Music info download still works! TrackID still works!:victory:
But not picture enhancement in album right? Hope you backed up TA partition before unlocking

im surprised at how this 'check bootloader is unlocked already or not' thread is confusing.
by the previous post, there is two 2 ways
1. try to flash doomlords kernel via fastboot, and if it doesnt flash means its NOT unlocked.
2. flashtool.
however the 2. flashtool method is very vague.. dont think anyone elaborated it.
So my same query is that if some error occurs after trying to unlock bootloader, and have reverted back to the stock FTF rom in original working state.
How do one check to see if my bootloader is unlocked or not?
whats the best easiest method???
Thank you!
just type in *#*#7378423#*#*
Go to Service Info > Configuration
And check the Rooting Status
If its Bootloader unlock allowed:Yes/No, then its not unlocked.
And if its Bootloader unlocked:Yes, then its unlocked.
Thanks

That just tells you weather you can unlock your bootloader via the command / flashtool e.g. If you carrier has locked your phone
On a unlocked bootloader the BE2 engine still works on videos ect just not pictures.
All I would do Is flash doom kernel or advanced stock kernel via flashtool (Click on lightning bolt /fast boot / click on put device in fastboot via adb now phone will enter fastboot then select kernel to flash which is in the middle on the pop up screen and then flash if it will take around 0 . 5 seconds ) if it fails then you bootloader is locked due to it cannot complete the command if is successful then it's unlocked and you can flash custom kernels take about 2 mins to do all in all

Can any one tell me how to unlock bootloader for SM-G350E
hi,all,im trying to unlock BL by flashtool beta6,but its say No loader found for this device
OS;4.2.2 ,423,HK
It says underneath it "cannot be officially unlocked"
So my guess is your bootloader is permanently locked. Type *#*#service#*#* and go to service info then configuration. It should say "bootloader unlock allowed:" yes if you are able to unlock it.

Use Google. A simple query like "how to unlock xperia z bootloader" would probably do it. But since that is such a far-fetched idea I understand how it could have slipped your mind...

Either try the latest flashtool and do it again or search for doomlord's post on how to unlock bootloader.
But before trying, I would highly recommend backing up your TA.img

Why are you using Flashtools Beta 6? That version has been superseded by the latest release on the flashtool site....
Go read Doomlord's post on unlocking the boot loader (which is the official Sony method)- you can do it quick and easy with fastboot......
As has already been said....read the post in Original Development about backing up your TA (DRM & BE) partition BEFORE you unlock your bootloader.

If it says bootloader unlock allowed: no, then fastboot is missing from your phone which is necessary to unlock the bootloader. So yes, you cannot do that if that's the case.

Yes it says bootloader unlock allowed: no, then there is not way to change the status of bootloader for yes.[emoji22]

Fastboot is always there... Even on carrier locked devices you can even flash a custom kernel if you want but it just won't boot you can also install a ROM for locked bootloader

Seriously?? Then might be we can find a solution somehow using custom kernels? But I have tried for hours I could never get into FASTBOOT mode. It went into FLASHTOOL(green light) mode but never into FASTBOOT mode. I inferred, FASTBOOT is missing from the device. I think it is missing.
Hi !
I am using the tutorial of this thread http://forum.xda-developers.com/z3-compact/general/one-bootloader-unlock-flash-firmware-t2905047 to relock the bootloader using flashtool but but it does not work me, because bootloader is still unlock
What can be the problem?
