[Q] Relock bootloader? - Xperia Z Q&A, Help & Troubleshooting

Is it possible to go back to stock firmware and relock the bootloader after unlocking it and installing a ROM?
I'm asking because of warranty purposes, and I didn't find a conclusive answer in the threads. Would flashing a stock
TFT relock the bootloader? Since I entered the IMEI on the Sony website, is it forever there?
Thanks!

At the moment, there is no known method of relocking the bootloader. Flashing a stock TFT won't change the bootloader status.

This question has been asked so many times
I believe Androxyde is making a relock FTF.
If you flash a stock firmware , the bootloader will remain locked.
Sony may or may not fix the phone for you if the bootloader is unlocked.

What about IMEI logging? Is it logged somewhere that I've previously unlocked the bootloader?

yes Sony will keep the log so unlocking is to lose warranty forever

Good news, thank you. I too am desperately waiting for relock every day.... Big regret for unlocking it... So I'll keep an eye on Androxyde developments.

Quoting from the thread you mentioned:

I did that already but not flawlessly.
I also couldn't unlock again with the known two methods.
Flashtool beta2 has a relock ftf file and I used it but the phone didn't start normally - I had to update with SUS
The bootloader was relocked EMMA confirmed also

OP do this:
Download the latest Flashtool
Install the Flashtool drivers
Connect phone in Flash-mode (power down + power)
Press the BLU button
Press the relock option
Put a stock .tft firmware in the Flashtool firmwares folder (this is required!!)
Flash the firmware (this is required!!)
Done
You will now have a locked stock xperia z

Awesome! But if this doesn't recover the warranty, I don't see many reasons other than BE2 to relock the bootloader. I was just wondering if I could make it look like the phone has never been rooted/unlocked BL, but then Sony records the IMEI, so they can find out..
What are other people's reasons for relocking the bootloader?
Awesome work, btw!

Why do you regret your unlock?
If you didn't want to flash a custom ROM, why did you unlock?
If you did flash a custom ROM, why do you regret it?
The ONLY thing you lost is Bravia Engine v2 and whilst you can already get v1 from an easy search in the forum, I'm sure eventually v2 will also be available as a mod.
About your warranty... It's a very well built phone with a lot of features aimed for durability, I see no reason for it just dying all of a sudden unless you use it very harshly and in that matter it would be a pain for you to get through warranty procedures anyway.

I just damaged my new XZ

First I unlocked bootloader with DoomLord method. Then did root. Then for same stupid reason I decided to relock it with flashtool for ZX beta2 and it didn't booted. It vibrates when i push the power button, but nothing appears on the display. Then I did the unlock and root procedure with fastboot on SDK and the phone responded to be connected and commands succeeded but nothing appeared on the display. Please anybody help. What I need to do? Fastboot seems to work. When i plug in to charge the red led does not stay on - it blinks

Close flashtool. Then download and install EMMA (official Flash Tool for Xperia devices) from Sony (https://www.google.ch/#hl=de&safe=o...le+emma+download&oq=sony+mobile+emma+download) and reflash your device with it.
Pay close attention to the instructions on the download page as you need to copy a couple files around before it works.
You need to boot to bootloader mode to flash. This achieved by totally turning off the device and holding VolDown only (not power) while connecting it to your pc.

Now I succeeded to connect phone to EMMA but it says locked phone. As I used relock option on Flashtool beta2 now how can i unlock it again? I tried DoomLord method and it gives me error write 'boot' failed. I did also the unlock process from Sony mobile provided and in the command window it says 'okay finished' but bootloader is stil locked
Excellent so far, helps narrowing down the problem.
EMMA only flashes unlocked devices, I figured you are unlocked so I recommended EMMA.
If you're locked, simply get Sony PC Companion and do a "repair" with it. Run PC Companion, boot up the phone, connect it, once PC Companion says connected click "Update firmware" or so. It should then say you're on latest firmware already and asks if you want to perform a "repair". Do so.
Just reread your post. Your device isn't booting, then of course the above doesn't work. You may try, I believe PCC also works with a device in flashmode.
However, you may also download SUS http://www.sonymobile.com/gb/tools/update-service/ and try with that. Its the counterpart of EMMA for locked devices.
Shut down your device (hold VolUp and Power for about 15 seconds, the device should vibrate 3 times in a row). Start SUS, select XZ and when it tells you to, connect your device holding VolDown ONLY. It should then do it's thing.

The unlocking and rooting part is not that scary as long as you have no power outage
The problem here was the relocking of the bootloader, there is no known way for that, yet.
I got my phone back thanks to schaggo .
SUS preinstalled it which means that it had been properly locked with Flashtool beta2.
But then no way to unlock again as I tried both ways known here as EMMA asked me to do.
I've rooted my previous X10i and my chieneese tablet wm8650, installed custom ROMs many times
but when I saw the black screen on my brand new XZ I just freezed, couldn't make my brain working.
Now curious about the BE - is it lost with the first unlock or it's back now?
There were some demo videos and music which are gone now and maybe this means BE is no longer working.
I wonder if there's a way to port back BE as FeraVolt did for one of his ROMs
So is your phone locked now?

Yes, its lost with the initial unlocking of the bootloader. Maybe it will be ported, maybe not, no way to know at this time.
I still miss an information: yours is locked now, ok, but could it be unlocked again (unlock allowed:yes vs. unlockballowed:no)?

He already lost BE, DRM and stuff, why limit one self to the less convenient dealing with locked bootloader when an unlocked device offers more flexibility and ease of flashing?
Flashtool for Z beta 2, replace x10thingblah.jar (search flashtool thread), hit relock button, reflash stock with PC Companion/SUS/Flashtool, done.

I have rooting status : unknown
This was said to be a bug - already fixed I think
I haven't tried unlocking again because I'm not sure that yesterday's death of my phone is caused by the relocking
I'm gonna wait and stay on stock for a while to see if this phone works without any problems.
About the BE2 I really don't know what to think : I did some screenshot with XZ on/off and there's no difference.
Then did the same with X10i (FeraLab' s ROM with BE ported) and again didn't find a difference between all of the screenshots including XZ'
Maybe it doesn't work on your X10 either. On my Z, I can make out a difference, especially with the provided stock images, which are VERY colourful on purpose I suppose, to demonstrate the oversaturation of colours BE2 produces
But I may ask again:
1. you reflashed your phone with SUS or Flashtool
2. after the flash you did not root or try to unlock again
3. when checking now (fully stock) your unlock status is "unknown"?
I ask, because root with locked bootloaders also makes the status unknown.
ive got my phone stuck on the sony sign instaling a custom unlocked bootoader rom when my phone has locked boot loader any help atall
i had root and everything was working but after install it said to fix permissions when they were fixed i rebooted but its stuck on sony sign.
any help would be gratful.

I tried many ways, including restoring everyting with PCC, fully original stock without root, without unlock, but it still says "unknown".
Again, unlock with flashtool 2beta, OK says "unlocked yes". and relock again, "unknown", and unlock again, "yes", switching freely...
Whatever I do, BE2 is dead, forever.
Somehow there is only one thing for now, with the fake relock "unknown", PCC or US or even OTA can accept device updating or restoring.
So to get BE2 back or get "locked" status, we'd wait for devolpers to work out something.

The Japanese devoloper way of locked root will make the status "unlock not allowed", whether device locked or unloced, which is just false information, don't worry.

After unlock/recovery/root, how to return to stock?

Hi there!
I've unlocked using flashtool, installed CWM Recovery and rooted using the recovery-only root.
Now, I need to return the phone to as stock as possible - certainly removing root, but relocking the bootloader would be a good secondary objective.
My current plan is to use the flashtool to relock the bootloader, then use the PC software to repair the phone. Will this work?
Thanks for your help
Edit: I've searched the forums but can't find an answer, including in the starting thread - please link to a relevant portion instead of the whole thing if possible
Further edit: There's no 'relock' option in the flashtool - huh?

As of now there is no option to relock the bootloader. You can unroot the phone by simply performing a repair system command in Sony PC Companion or flashing a stock rom. This has been explained in every single rooting or custom MOD thread.
Ya you are right. Relock bootloader using flashtool and repair or flash a ftf from flashtool.
And IIRC in the beta version of flashtool u will find option to relock under BLU. And btw u won't get back DRM keys and no Bravia engine.

Thanks - I expected there to be a separate button for relocking - whoops!
I've flashed the stock ROM and that's gotten rid of the root. It also says that the bootloader can be unlocked, so that seems all perfect as far as I'm concerned. Thanks for your help, ladies and gentlemen.

[Q] How to check if the bootloader is unlocked.

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.
Sent from my C6603 using xda premium
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

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.

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

[Q] Re-lock bootloader xperia t lt30p

Hi, I unlocked the bootloader on my xperia t lt30p one time with intention to root it and install custom roms but never did as I nearly bricked it when putting a kernel on. I managed to put what I think is a stock kernel and rom back on, but I went to update it the other day and pc companion says that it could not complete the operation because the phone has been modified. I read somewhere that having the bootloader unlocked can cause this, so I wish to re lock it. Could anyone point me in the direction of a good tutorial to do so? Cheers...

the link provided by our friend is quite good, that's where you have to head over
and about the tutorial, tha't so easy, just flash that FTF file via Flashtools
power off your phone, open flashtools, select flash logo, then FLASH MODE, then connect your phone as you are pressing down the VOLUME DOWN button, and let it do the rest
disconnect and enjoy your relocked bootloader
So I won't need to re flash the rom again? sorry. I'm a bit of a noob at phone modding. Pc's I can do. Not phones yet. Hahaha.
no, flash the relock ftf found in the dev section, and it just relocks your bootloader, your rom will stay the same

RElock won't affect you rom, BUT if you unlcok AGAIN, then at the very first start up of the phone when it is the first time after RE-UNlocking, it will have a factory reset
just wanted to let you know
but for now, NO, it won't touch your firmware

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?
