Hello,
I've been looking at these forums a lot for the past several months, reading the various guides(lots of conflicting and unclear info on them),and some are reporting successes and others failures on the same ones. So, I'd like to ask you guys what I should do. Here's my phone info I got from the hidden menu:
P76920h,
4.1.2 Android,
3.0.31 Kernel Version,
Factory Version of Aug 14 2013
AP bootloader version of LK May-2012
T-Mobile brand phone
Well, thanks, and happy to post more info if needed.
Edit: Thought it might be important to note that I am rooted and I have Artas recovery installed(at least I download the app and I ran it and recovery seemed to be non stock)

Thanks, but our phones are drastically different, so I'd like to hear some other feedback, because if I remember correctly, your bootloader is different.
I have this phone too. Unlock bootloader of this phone is the same as other variants, except that you must use JB rom of P760 to unlock, so it's hard to do steps because your screen will be mirrored and touchscreen goes crazy.
- First flash v20b kdz of P760
- Then install fastboot driver, plug your phone, type oem-unlock command
- After that bootloader will be unlocked.
- Finally, fix touchscreen
PM me if you have question

Number1) unlock bootloader, it is free and official from unlockbootloader.sonymobile.com
number 2) download flashtool, find it urself......
number3) Once clicked, you will then get a pop up where it will read “Are you really sure?”, click on “Yes, I’m sure” and there you go, you now need to open the command prompt in your computer. Dial *#06# in your phone to get the IMEI number. Note it down at the safe place as it may be required at a later stage.
•Connect your phone to the computer and then in the command prompt (shift+ right click in fastboot folder under "system c:/flashtoo"l, you now need to enter in the below mentioned command.
number 4)type this in "fastboot -i 0x0fce oem unlock 0Xkey", replace key with the key u obtained from the site
number5)“” •Ensure that the KEY which you have replaced with the IMEI is the correct IMEI number. After entering the above command in the command prompt, you need to then follow the on screen instructions so as to unlock the boot loader.

correct! If you want to acces root you now have to download http://forum.xda-developers.com/xpe...de-root-cwm-unlock-bootloader-custom-t2403929 that and run the runme.bat file. Connect your phone and you should be running ICS 4.0.4. I had the 89 when I rooted. Enable usb debugging, you can search on how to do that and after that you connect your device to your pc and click 1 on the runme.bat file and hit enter. Wait for the magic and if you are stuck at ''if succes i will tell you'' part, wich I was. Just unplug your phone, reboot and go to your appdrawer and find the ''make a copy and restore'' app and click on find a copy and click on ''root'' (something like that) and after that click restore. Reboot and then download kingroot, the latest is recommended. And roooooooot . After that you may want to replace the kingroot root authorizer with super su. This is optional but I recommend it. Follow http://androidmtk.com/replace-kinguser-with-supersu that tutorial and you should be good to go!
Well this thread is extremely old so I suppose it should be closed.

First flash the European open V20B kdz and make sure you have a signal (you can make calls and etc.).
Next leave your phone on for 30 mins. and then try to unlock
Note: if you have already tried 30 mins and it didn't work, leave it on longer before trying (eg try the unlock after 8 hours)
good luck
Hello !! I already tried to flash a v20b KDZ under section "European Open" , but unfortunately when I go to see the in the phone information appears only " P760v20b " without " EU-XX " acronym . I try to flash several v20b KDZ with the same result...Can we help me to find a valid v20B KDZ ?? Thanks
So you are saying you can't make calls?

I just unlock my P768f boot loader yesterday. Europe Open Link for download V20B is forbidden now, I used V20C and it work fine. Not sure why your phone only reboot to normal mode.
I just follow this thread for P768 http://forum.xda-developers.com/showthread.php?t=2313794. It work at a first try. I'm already on stock JB rom (P768f) for about 2 weeks before unlock bootloader.
Just want to confirm that Europe Open V20C also bootloader unlockable.
Hello artit , then you tried to unlock your bootloader on v20c without reboot the system after flash for 2 weeks ?? So , yesterday i flash v20b KDZ , what do you suggest I wait ? It's possible that my bootloader is corrupt ?

I don't think your bootloader is corrupt. For me, my JB P768f came out about 2 week ago but any P768 is not bootloader unlockable (adb reboot oem-unlock just normal reboot phone). So if P768 user want to unlock their bootloader they must flash P760 V20B rom, as I did.
If you want to try again please flash Europe Open V20C, download link from http://csmgdl.lgmobile.com/swdata/WDLSW/LGP760/ANEUWH/V20c_00/V20C_00.kdz
After flash it reboot your phone, enable usb debug mode and wait about an hour (I also not sure what this does but many people said you must wait) then connect your phone in command prompt try "adb reboot oem-unlock" again.
Thank you so much then I'll try to wait a few hours , if doesn t work again is possible to replace my locked BL with your just unlocked ?? So I should have full guarantee of success.

You are not turning your phone off at all after you flash the kdz right? You are not suppose to turn off the phone. Not sure if this will help, but one person reported success by leaving his phone connected to the charger for hours before it finally worked for him.

Thanks for the reply , so you advice to power off the phone and attach it to charger for a few hours and tray again ?

No, first flash the kdz (and don't turn it off at all) and leave it on the charger for a couple of hours

Hi guys,
I had been passive all this years in this forum.. many thanks to all contributors in this forum.. which had helped me a lot to root, unlock my bootloader, custom ROM, etc to my various phones, sony xperia, samsung, asus padphone, etc
now I guess it is my turn to contribute.
this L9 P768 of mine to me is the best phone I have so far, cheap, light, powerful enough to my need, battery is not so good though eventhough it is higher capacity compare to other phone in same range but hey.. it is removeable battery !!
last 2-3 months I was happy with STOCK ROM, but 2 days back I want something new, I want custom ROM, especially now someone have released custom Android 4.3
without any research, I applied CUSTOM ROM, and stuck in security error, but after reading I realized this phone is much more powerful than I thought..
I think this phone is UNBRICKABLE
cut story short.. i was able to bring back my phone alive using fastboot mode and now running stock europe open V20C (thank you for the mirror contributor.. and f*ck you LG, I kept getting permission denied and half finished download)
cut story short again... I followed various threads, and stuck in command "adb reboot oem-unlock" my phone was rebooted without getting into bootloader unlock confimation / warning screen
I was using windows xp (with all drivers installed properly, fastboot, adb, etc)
I was frustated like some few of you here that had been trying to unlock bootloader (some even tried for months..)
finally few minutes back, I got my breakthrough, I tried using my "working" laptop that has linux installed and issue command
adb reboot oem-unlock
and phone was rebooted and this time I get the confirmation / warning bootloader unlock screen !
hurray !
so to those who stuck., maybe you should try adb for linux.. here is the version that I have
[[email protected] ~]$ adb version
Android Debug Bridge version 1.0.31
hidden menu is showing my bootloader unlock
My friend has got LG P760 and wants to put CyanogenMod on it. It came with 4.1.2 V20C Poland from PLAY. Entering adb reboot oem-unlock command in command prompt was just rebooting the phone, so I flashed 4.1.2 V20H Open Europe with KDZ flasher (after modifying hosts, setting miniserver etc). Even after that it still only reboots. I was using bundled USB cable, having SIM card inside, waiting 30 minutes since boot - still nothing. What I have to do to enter bootloader unlock mode?
Man, I figured it worked on all those. I'm on the American version and we can't unlock at all. You're lucky. Hopefully someone else will come along and help you.
Polish is hard by the way. Props

Hello I am trying to install CWM and then Cyanogenmod on my phone. But I cant boot into the fastboot menu.
Thats what i have tried:
I enabled USB-Debugging
I tried the following in the terminal:
> adb devices
Output:
List of devices attached
5E92000600000001015D7E8403019012 device
> adb reboot-bootloader
> adb reboot bootloader
> abd reboot oem-unlock
My Phone is booting after every of this commands normally... but this is not what I want. I want to boot into fastboot mode to install CWM and then CM 10.1.3
My System details are:
Phone: LG Optimus L9 P760
Android: 4.1.2
Baseband-version L6260_MODEM_SIC_01.1230.00
Kernel version: 3.0.31
Build-Number: JZO54K
Software Version: P76020h-EUR-XX
Did you wait 30 minutes? Which procedure did you follow? A link please.

Same problem here. Waited 30 minutes, tried with v20c and v20h and same results...

www[dot]hackmyandroid.com/unlock-lg-optimus-l9-bootloader-running-jelly-bean/4595
Sorry I can't post links as newbie
But I think I forget waiting for 30 minutes.. I tried at first under Android 4.0 ( Ice cream sandwich) to unlock the bootloader but this does not work. So I updated it on Android 4.1.2 (Jellybean) and maybe I forget waiting. Don't know.. I will try it today again when I have time and edit my post later.
EDIT: Moreover I read that unlocking the bootloader under ice cream sandwich does not work. The Phone must be updated to Jellybean is that right?
I let my phone sit for over an hour and it didn't work for me. Shuttle over at the Cyanogen forum recently cracked the bootloader of the Optimus Sol. I sent him a PM so let's cross our fingers.

I solved the problem now.. be sure that your device is up to date ( I mean updated to Android 4.1.2 and that your device is more as one hour up) When you are following this steps you can unlock the bootloader
I try this 20 times , without reasons...I think is an hardware release problem. If you open your back cover , you will see Wifi and GPS modules . Check your number release. My numer is 1201 and is unlockable device , a lot of people with different numbers on it ( lower like 0800 , 1001 , ecc, ) are able to unlock the bootloader...Please check your numbers...I suppose the higher value isn't unlockable and the lower is unlockable.

Follow this guide, It will work https://forums.oneplus.net/threads/...wrp-root-nandroid-efs-backup-and-more.345478/
Hello again,
I have followed these steps but it did not work. When I started my OnePlus 2 in bootloder and then you have entered the code fastboot devices and my phone is seen. The Code fastboot devices is also still good but if I fastboot oem unlock code entry, nothing happens I can not choose between one and two I saw hebop an explanation on youtube. Everything just stays the same and my phone is not fully datawiped and all files are still there just. The Code fastboot reboot my phone restarts. what can I do about this?
As I understand you have follow that guide and now you have
enabled in settings, developer options,
OEM unlocking.
Then in fastboot mode device is discovered by "fastboot devices" that means drivers are properly installed.
Whenever your try to execute "fastboot OEM unlock" your device restart but don't unlock the bootloader.
What I would do is different things first to factory reset and try to unlock again.
Try on different computer.
Flash latest official signed rom and try the unlocking procedure again
