[SOLVED] Galaxy S6 G920FQ Bootloader unlock? - Galaxy S6 Q&A, Help & Troubleshooting

As I said in the title my device is G920FQ model. I want to try custom roms, is it already bootloader unlocked or is there a way to unlock bootloader? I've searched this place but couldn't find anything.
Also if it is bl unlocked can I just flash TWRP without rooting my device first?
EDIT: Got it all sorted out.

[Q] Doubts with locked bootloader and unlocked bootloader?

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

Dial *#*#7378423#*#*
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!!

Already Rooted ¿can i unlock the bootleader for free?

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.

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

J700F Bootloader

I have many questions with this bootloader. I'm new to this things. Sorry. Btw I have the J700F J7(2015) model.
1. Is there any way to know if my phone is in locked bootloader or unlocked?
2. I'm planning to install the Pixel Experience rom and I've read that i must unlock the bootloader first. I know that I must be from stock rom. Then I will install the TWRP, then root, then proceed to flashing the rom. In this process, where will I unlock the bootloader? Do I need it to be unlocked before I install the TWRP?
3. I know that I can google it, but is there an easiest way to unlock the bootloader?
Sorry, I have many questions.

[Q] BLUnlock not allowed solution ?

Hello every one. I have a c2105 from Vodafone and I'm convinced that there's no option to unlock my bootloader, but recently, I found two videos on Youtube which show a software that can unlock it when it says "NOT Allowed"...
Links:

Has anyone tried one of these softwares and has it a chance to succeed ? :fingers-crossed:
Thank you :laugh:

Flash recovery to boot via fastboot and flash rom and after that flash boot from that rom
There is a way to install a cwm while BL locked. Although in order to flash a custom ROM you need to find a good one and one for BL locked (which there aren't many at the moment)

Not able to boot into recovery mode

My "Coolpad Note 3" is not booting into recovery mode after Flashing Cool ui 8 V22 Rom & TWRP Recovery. However Normally its booting absolutely fine and its quite stable Rom. But I seriously need to flash TWRP in order to install SuperSU and Xposed Installer. Anyone Please suggest any solution Asap.
(Also My Titanium Backup(Apps+Data) could only be restored after granting root access).

Did you flash the correct recovery for your model number?
Have you tried flashing the recovery again?

Yes I Have flashed the correct recovery with SP FLASH TOOL (Mtk 6753 Scatter file). It shows that it will boot into recovery mode but again screen blanks and same process repeats.

Did you try booting to recovery using adb?

Do you know of your bootloader was unlocked before you flashed the recovery?
If it was locked then that is why it won't boot to recovery.

Yes, it's the same for all android.
adb reboot recovery
This still doesn't work if your bootloader was locked when you flashed your recovery.
If the bootloader was locked, you'll have to flash a copy of your stock recovery.
Then unlock the bootloader, then flash the recovery. It will probably work correctly then.

As I Know, Coolpad Note 3 comes with pre-unlocked bootloader. And Earlier I had TWRP installed in it with the same method. I dont think so The Bootloader was Locked as I Have flashed Cool Ui 8.....nd that was done quite easily.

Ok, if you had TWRP on it before then it isn't locked.
Did you at any point create a nandroid backup while that version of TWRP was installed? Have you tried flashing that same version of TWRP?

Yes, those are nandroid backups.
Can you flash the recovery that you used to create those backups? Or is that the same recovery that you're trying to flash now but can't get it to boot?

I dont remember the exact version of Twrp as its not officially available for my device. But ya..I had tried to flash 2-3 recovery.img 's (including the one which I flashed earlier). But no one worked...it just repeats the same process.

The device may have came with bootloader unlocked when you got it, but you flashed a stock update Cool UI 8, if that stock update came with a locked bootloader as part of the update package then your bootloader is locked now, and that would still explain why you can't flash or boot to TWRP.
Verify whether the Cool UI 8 v22 firmware itself came with an updated and locked bootloader. It has nothing to do with whether your device came with unlocked bootloader.

Ya I Have checked...Coolpad has locked bootloader for this firmvare version. What should I do now....Should I flash the earlier version of cool ui 8 or Is there any method to unlock ot manually?
(Ps: Not able to find Adb & Fastboot drivers for this device)

I'm not sure about the bootloader, I didn't find anything about unlocking bootloader for Cool UI 8 v22. Does it have a "OEM unlock" setting in system settings? If so, enable it and then see if you can flash/boot TWRP. Try fastboot with the following command:
fastboot oem unlock
But I did find something about how to root your device, if the information is correct. You might be able to root what you have then use FireFlash or Flashify to flash the Xposed Framework and get it working. You probably won't have unlocked bootloader or TWRP though.
But, you also might be able to downgrade to your previous firmware but I'm not sure if that will unlock your bootloader or not. The locked bootloader might not allow you to downgrade your firmware.
