Hi.. I have Sony Xperia (ST21I) with build number 11.0.A.4.27 (android version 4.0.4). Few months before it rooted this phone with a unlock flash tool. I am sure that the phone is rooted now. And i managed to install a Clockwork Mod too with CWM installer.apk file. And tried too boot into clockwork mod. It worked. Now I don't know which bootloader I am having? A locked bootloader or a unlocked bootloader. This question may look silly to people who are really fluent to android. I never carried any process to specifically unlock my bootloader. I am asking this question because I have read that "You can't root your phone without unlocking bootloader". If what i read is true does that mean i am having a unlocked bootloader?? So now is it possible to flash a custom rom for unlocked bootloader? Thanks in advance.
only few roms

You probably have a locked boot loader as bootloader can only be unlocked by a specific key.
I too have a xperia tipo and it can be rooted without unlocking the bootloader. I used unlockroot to root it.
Thanks Guys!!

Guys i really sorry for this noob question but im kinda lost whit this phone...
I was using a moto x but this droid ultra its different.
Actually my phone has the 4.4 firmware and im already rooted (used towelroot) ¿there is any way to unlock the bootloader for free?
EDIT: Im lost... Completely lost.
Towelroot doesn't work, towelpieroot its temporal, I can't flash twrp via "app" or fastboot (cuz boot loader locked)...
I dont know what else can I do... Sorry if this was asked before but I can't find answers in the forum.

Lock again the bootloader ¿its possible?

Update first then flash twrp. You won't lock the bootloader. Once unlocked you stay that way.

Thank you Casey, ¿even if i flash motoboot.img whit rds? That file contain the bootloader. Just in theory

I sucessfully installed Orange Fox Recovery in my Redmi Note 7 Pro (violet). But then after that I wanted to go back to the stock rom so I flashed it with Mi Flash. The Rom which I flashed was Global Stable Fastboot Rom (Version 11.0.8.0) but after flashing an error appeared that the system has been destroyed. Then I tried to unlock my bootloader, that took place successfully and my phone booted but the bootloader was still unlocked, I want to lock my bootloader. But whenever I do this the System Gets Destroyed.
You probably have the Chinese version and are flashing the Indian rom. Try to flash the Chinese rom and lock the bootloader and see if it works.

I am also having the same issue. I have tried multiple methods. I flashed Chinese rom, and then tried relocking the bootloader. It did not work.
I also tried flashing MIUI 10, and after flashing the fastboot rom of MIUI, I tried relocking bootloader. It did not work as well.
I want to relock my bootloader.
After unlocking bootloader I am facing just one issue, that is, my internet goes off (volte signal + internet) while receiving an incoming call. While it does not goes off and internet works fine when making outgoing calls. Are you also facing this issue? I am using Airtel.
Also, can someone please help us out?
I have did same it will work for me with unlocked bootloader and got a little issue with accessibility player in youtube
Not a big deal ?
Just in case anyone wondering. I have XZ2 AU (SOV37) with Bootloader unlock allowed : No
So I use qUnlocktool, paid some money for it (nugsm), and unlock the simlock (even though it's already unlocked to begin with)
And after that Bootloader unlock allowed : become Yes.
Then I flashed Android 10 global ROM, unlocked Bootloader, phone unable to receive signal.
From there all I have to do is just to restore the backup from qUnlocktool, as result I have unlocked Bootloader and unlocked SIM.
Hope this can help some people.
Though by flashing to Global / Custom ROM you will lose NFC. recommended to use debloater (magisk) to remove NFC related services to prevent battery drain.

I bought it from this site, https://nugsm.com/product/sony-xperia-cable-unlock-0-counter-supported/
they also provide the software required for it
Yes it's possible, need to pay for service.
qunlock can do, even they only described as sim unlock.
Tried with SOV37 and 702SO

I tried unlocking an Xperia XZ2 SOV37 with qUnlocktool and it worked. It showed Bootloader unlock allowed: Yes, and then I proceeded to unlock bootloader with fastboot command. However this error showed up:

I tried on both AU stock rom as well as lastest android 10 UK Customized (H8216_52.1.A.3.49-R8C_Customized UK) but both failed to unlock bootloader.
Can you help me solve this problem? Which global rom did you flash?
