Very simple thing to unlock the bootloader !! Download the application terminal emulator on Google play and open a window.
Type su ans give the root access
Type reboot oem-unlock ans the phone will reboot un fastboot mode ! Press volume up and your bootloader is unlocked

If your going to attempt this on a P769 it didn't work for me, it just rebooted just like the other methods. It's worth trying though. But thank you OP.
Yeah. Not gonna work on the metropcs 769 model. This one is a pita

I too had tried this a few months ago, it was a no go.
But I bet this works on a p760 like a charm since their bootloader is unlockable

Hi,
This is my first post and have a few questions about my phone. I recently rooted my s3 and flashed the siyah kernel by CWM and also flashed jkay framework. I am going to Europe for two and a half weeks and would like to unlock my phone. I have read about using the dialer to unlock the phone. But it only works on 4.1.1 and my phone is 4.1.2 so I was thinking of dual booting my phone with my current stock rom and a stock 4.1.1 and then unlocking it. I was wondering if this would work.
I have another question is there a way to tell if my bootloader is unlocked. I've researched this and eople say of the Samsung logo stays for more than a second its locked. I have also read people saying only the verzion one is locked. When my phone boots I get the siyah logo then the 3 UK boot animation then the Samsung logo glowing for about 3 secs.
I am grateful for any help. Thanks in advance.

If you're rooted, use galaxsim unlock to sim unlock the device. Bootloader lock is completely unrelated. Its only locked on verizon phones

Price of unlocking via the play store us cheaper than a replacement motherboard so do test your EMMC for sds as per the "sudden death - are you covered?" Thread in general. At least make sure you're fully aware of the risks before flashing 4.1.1

Ok so I managed to get it unocked. At least thats what it says on my phone. But when I restart it and put another sim in. It asks me for an unlock code. I used galaxiSim unlocked. And downloaded busy box. But am a little confused what was I suppose to do with busy box?

Use this file to unlock your phone. Busybox enables the app to unlock your phone it is used by many apps. Have you actually installed Busybox or just downloaded the app.

Hi all I'm a new member here so please excuse me if there is a fix in the forums that I didn't find.
I own a nexus 4 and I rooted it using an application but didn't unlock the bootloaders. The root checker says it's rooted and I have supersu access but when I boy it I don't see the lock under the Google logo. So I Wanted to try the xperia z feeling so I flashed a ROM of it. When it booted I noticed nothing changed except an xperia launcher. note when android 4.3 came out I didn't get the ota updated so I suspected it's because of the ROM and I want to go back to stock android and I'm not able to do it. I lost my backup while trying to upload it to drop box. Please help me
Sent from my Nexus 4 using xda app-developers app
You probably used a tool kit for root is my guess and those same toolkits can bring you back to stock if this is what you desire.
I guess I'm not fully clear on what your after but when changing ROMs just boot to recovery, wipe ALL, then flash ROM and whatever else needed (gapps kernel etc)
I suspect you didn't do a full wipe when flashing your new ROM.
If I didn't answer your question fully just let me know

Sent from my Nexus 4 using xda app-developers app
I don't won't to sound rude but I feel you have a lot of reading to do before you mod your phone. The only way you can loose your imei is with great neglect.
Also learning at least the basics to adb should be the first thing you do before you root your phone.
Again, not trying to be rude here, but if you don't do some research, at least the minimum like read all the stickies in your phone section, you have a real high chance of running your 350$ phone.

No offense taken. I know that I'm not that Good in android but I did own a Motorola defy and I rooted it easily and used alot of Roms on it it was a mistake to not unlock the bootloaders. and the imei issue happened to my friend and we both wondered why it happened. I really appreciate you helping me. And o really want to get my phone back to stock. I thought about using warranty but I'm in Jordan so I can't I have to do everything by myself.

This might be a dumb question but since unlocking the bootloader
is so hard maybe we should try to find a way to get past the LG Security error without
unlocking.
The phone checks for images signed by LG on boot up. Unless LG decides to release custom roms we're stuck with the wonky method.
