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.

Yes it works - tested by me
I unlocked my bootloader using the sony unlocking process. As it was saying my phone couldn't be updated due to modified software, I flashed a stock uk unbranded rom on to it (mine phone is a 6602 bought in Qatar, but the firmware says it's for a 6603).
I then used the flashtool to lock my bootloader. When I check the service settings it now says that unlocking the bootloader is now showing as no. Reading another thread that said by using the SEUS to repair your phone it's possible to change it back to yes, I tried it, but SEUS says that it there is no software available for my phone. Sony Update Engine doesn't have software available for my phone'
Anyone able to get my bootloader unlocked again?

Howsit Guys
Need a lil help here. Im currently on firmware- 10.4.1.B.0.101 with [Root & XZDR] http://forum.xda-developers.com/showthread.php?t=2643898 <-- via this method.. all Works sweetly.. Problem is that i want to unlock my bootloader. Ive checked in the service menu, unlocked bootloader is allowed.
I am currently trying to unlock bootloader with latest version of Flashtools(unofficial way).whilst phone is on, i connect cable, startup flashtools, it detects device. Then i click on lightningbolt icon, to unlock bootloader. menu comes up asking to remove cable, power off phone n goto flashmode.
When i get to the part where it asks to select my device, i click on xperia z. And i get a FAIL message saying i cannot officially unlock bootloader?? Do i need to be on stock .244 firmware or stock kernal to unlock ? Or am i going through it the wrong way. main reason i want unlock bootloader to install cyanagen mod11 nightly.
Thnx
Done
Sorry for the silly post.. managed to unlock my bootloader..
Hello. I want To flash 4.3 Stuck Rom For my Xperia TX. Its Unlocked . Should I relock it Or something else ?
please tell me
Unlock is Unlock bootloader or unlocked to work with all sim?
If you have unlocked bootloader just do it next step:
If you want to flash it with Flashtool, you don't need to lock your bootloader.
If you ask for update with Pc Companion or Update Service, furst lock your bootloader and then try.
Best regards.
