[Q] Relock bootloader?

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:
"PLEASE XPERIA Z OWNERS, DO NOT RELOCK YOUR PHONE WITH THIS TOOL. IT DOES NOT WORK FOR XPERIA Z"

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.

It should do. Please tell us the error you get. However, if you are trying to flash that ftf file you do not do it in pccompanion, you need flashtool

problem still comes
iam flashing with no problems with flashtool, and the ftf works fine on my phone, then i take it to sony pc companion and trying to update it with it.
then i get an error that custom firmware is installed

OK, if you have unlocked your bootloader you can no longer use pccompanion.
That would have been explained when you went through the process of unlocking the bootloader.

is it possible to lock it somehow again?

Probably not. You have voided your warrenty when you unlocked and relocking the bootloader willnot hide that fact.
You gave them your IMEI number when you unlocked, and you modified your trim area (That's why you lost drm keys) and relocking does not restore the TA.
PS, No need to say thanks in a post, just use the button.

oh okay, so it didn't really matter that i reset it to factory, they will still just give me the same message...
damn Sony, i will never buy a phone from them again...
seriusly they destroyed my phone at their repair service, but now i just have to argue with them, don't think that XDA can help me with this anymore then done now.

well if sony broke the screen you may have a case to get them to fix it.
But it is very clearly stated that you lose warrenty when unlocking the bootloader. I think all carriers do the same (If they let you unlock at all, Sony are very good at this and this is why they have been voted xda's OEM of the year for the past few years because they are so Dev friendly)
You just need to read the fine print a bit more carefully I think

well i dont think that it's too clearly stated, when they write that you may void the warrenty, it doesn't say that i void the warrenty, only that i may void it.
hmm yearh, Sony isn't that bad at all, and their products work...
well think it will be alot easier now to talk with Sony about the problem now.
is there some way i should mark this thread as solved?

hmm now i get a new bug after i did this...
I can't install apps from google store, getting error 403.

Fastboot issues,bootloader (un)locked?

So I've unlocked the bootloader on my xperia Z the official way. Entered the unlock key and it was successful.
However, if I try to write a recovery in fastboot I get the error : Remote: not allowed.
I have made sure I have the correct drivers and all but it still doesn't work. Even tried unlocking it again with a second unlock key.
How can I fix this?

bump, still no cure found

Any help would be appreciated

Try to boot in recovery does that work?

not only allowed or not
if you have locked bootloader it says it is allowed
if you have unlocked bootloader it says that your bootloader is unlocked
you can check your bootloader by this way , cause your error determines that u have lockbootloader

Unlock bootloader without losing DRM keys
Hey guys
I have a similar problem. I want to flash DoomLord's custom kernel but the command is not allowed. I found out bootloader unlock allowed does not mean it is unlocked yet, so that is the problem why it is not allowed. However, I do want to backup my DRM keys first. Is this possible? My phone was rooted before I flashed 4.3, so it is not rooted anymore.
Oh I have a Xperia Z 4.3 c6603 flashed with the ftf supplied by doomlord.

u welcome!
just checked the screenshot says that BL unlock allowed: status YES which define that ur BL (bootloader) is not unlocked yet!
make sure u are using the appropriate tool that works for ur device after u get the BL code from Sony, then follow the instructions in Sony where u got the information about unlocking BL
first off... do not proceed with bl unlock until you backup your TA partition cuz u might brick ur phone after the unlock is done if something goes wrong!
is it's not really recommended... u can still root it with a locked bl and enjoy ROOT privileges... FYI, unlocking bl will erase DRM keys and might affect on ur TA partition too.... so keep in mind that Bravia Engine2 along with Track ID will stop working after unlocking ur BL
TA Partition backup

Unfortunately, as of right now, there's no way to relock the bootloader, and your DRM keys are lost forever.
You can try the custom kernel in the ROMs.. section, which includes a DRM fix, which maybe can restore some of the functionality of the camera.

A lot sure has changed since my previous phone (Z5 compact). Back then, simply flashing stock firmware automatically relocks the bootloader.
I'm surprised that's no longer the case.
Guess we'll continue to see little to no development of this phone until major breakthroughs.

There is no way to re-lock your bootloader once you have deleted the TA partiton. There are so many warnings on your way to unlocking that tell you this repeatedly.
You can use sToRm//'s Sony Xperia XZ Premium TWRP + KERNEL + ROOT + DRM fix/restore
app to enable your DRM again, then you can take pictures and everything is as before.
