I received a warranty exchange and it came with 20f preinstalled so i did adb reboot oem-unlock. How can i tell if my BL is unlocked? No root
Get into software upgrade mode. Turn the phone off. Plug the phone into your computer, and hold volume up and down (might be another combination like volume up and home. Keep trying.)
If the bootloader is unlocked, it should say Bootloader unlocked on the top left of the screen. If not, it will say nothing.
Or just dial 3845#*769# and scroll all the way down, hit bootloader unlock check then click the button, too easy

Yeah it does, just type it in and scroll down then you hit the bootloader and you will be able ti see if your bootloader is unlocked or not. It won't unlock the bootloader but you can see if its locked or not.

No, that does not work (well on some roms, with the proper u-boot it will). The best way to check is putting phone in s/w upgrade mode. If it's unlocked (and on a V20F, V20H or a unlockable jellybean U-boot) it will say Unlocked Bootloader.

Hi,
I bought a second hand atrix, it has Android 2.2.2 with motoblur, and it is probably rooted.
I want to install CM7 ( beta ), so i want to follow the steps of the tutorial, and one of the first ones is unlock bootloader.
I don't know if the bootloader is already unlocked. Is there any way to know if it is unlocked? If not, nothing happens if I unlock it twice, right?
I am pretty affraid of bricking the phone...
Thanks!
While the phone boots up, the text "unlocked" should appear if its unlocked.

It doesn't appear anything.
But if i hold the volume button (down) i can get to fastboot, android recovery....so it means it is unlocked, right?

I want to Flash custom Kernels in my phone which is a wt19i . Can someone tell me how to do that
There are many post that teach you this.
First unlock your bootloader and you can flash the boot.img or ftf with either fasrboot or flashtool

Check out this thread:
SE Bootloader Unlocking v1.6 by quangnhut123
hope this helps!
It's your phone sim locked?
If it is then: do you have access to fastboot mode?? ( turn off your phone hold the volume up key and connect the phone to your computer without letting go of the key, the notification led should turn blue. That is fastboot.)
If yes then you will need to unlock your bootloader either the official way here http://unlockbootloader.sonymobile.com or the test point method here http://forum.xda-developers.com/showthread.php?t=1285285.
If you don't have access to fastboot then you will need to simunlock your phone first and as of what I know and at this moment you will need to pay for it.
Once you unlocked your bootloader you have to flash the kernel of your choice using flashtool here http://forum.xda-developers.com/showthread.php?t=1351309
You cannot enter fastboot if bootloader is locked.

well i know of people able to go into fastboot with locked bootloader the problem is when you have a sim lock and the bootloader unlock allowed: no message in the service menu then you will have to pay to unlock the sim along with the fastboot.
¿How to know if my bootloader is locked? I searched on the hidden menu and found nothing but the bootloader version. I'm looking forward to unlock it so i can root and do stuff.

I'm not sure it's the easiest way but you can go to fastboot with method wrote here http://forum.xda-developers.com/showthread.php?t=2221102. But first you will have to flash jb V20* ROM. If you have first screen where you are asked if you want to unlock bootloader = locked. If second screen with quick guidance = unlocked.
WARNING! Be careful if you don't want to unlock bootloader watch which button you press.
You still didn't answer his question. I would like to know as well. Is there a way to tell if my bootloader is unlocked or locked?

Of course it's locked, every phone you get will have bootloader locked. Unless you have an S4 or S3 as far as I know.

As far as I know, not every phone comes with a bootloader closed unless some phones are able to change roms and stuff without needing to open this.
If your on JB, just go to the dialer and type 3845#*760# then scroll to the bottom to bootloader unlock check. (if you have differernt L9 - 3845#*7xx# - your numbers)
Another way to check is to go to software update mode by switching off the phone then holding volume up while inserting the USB cable. If your bootloader is unlocked, it will say so in the top corner of the S/W update screen.
If you havnt unlocked it, it will be locked by default.

U need a PC to install lg mobile support tools and drivers to flash Europe 20b kdz..plus more..only then u can unlock the boot loader..I would say no its not possible
Your signature says 769 variant..so you got do the above..

Maybe from terminal emulator,you must root your phone,in terminal emulator type "su" and give it root rights then type reboot oem-unlock.I dont know this will work...
Tried the "su" thing here... normal reboot
would be awesome
yeah wish I could do that, unlocking BL is so much, I only rooted mine.
So I unlocked it for the 769..flashed cm sucessfully
...then went to stock with flashing a kdz. Seems boot loader is relocked on stock but I read somewhere its only temporary, can't remember where..so how do I unlock it again? Without the whole kdz 20b europe process again.. I know its locked cause I got security error when flashing recovery/ROM..got it back with fastboot
Also hidden menu says locked...
However sw upgrade mode still says boot loader status unlocked..

I envy you so much, why in the world would you go through all of that simply to relock?

Hi matthewstice, I think that your bootloader is only apparently locked, you need JB roms (or at least load JB u-boot and x-loader with fastboot)... , I'm not sure, but I read something about it here, just don't remember the link.
Cheers. Good luck.
