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.

Hey friends, I have a Sony Xperia Z device. First, i unlocked it's bootloader, then i re-locked it using the TA-partition backup. But now I want to RE-UNLOCK the bootloader to install the new Android 5.0 and I don't know how to do it. Do i need to do it in the normal way?

Do you have your DRM keys? The you can restore them with the tool and it will relock your bootloader.Try to do it on the same version that you backed them up from. If not you can use flashtool.
and then follow this one: http://forum.xda-developers.com/z3-compact/development/stock-firmware-23-1-0-690-generic-t3056413

Hello
In order to use Realme's flashtool you must have unlocked bootloader.
I would like to ask if after flashing a rom with flashtool, the phone remains unlocked or the bootloader is locked
