Despite all efforts I can't unlock bootloader on my p760. After sending adb reboot oem-unlock command the phone reboots normally. I tried almost all the ideas I've found on xda - flashed different versions of v20b, v20c, (europe open and country-specific) even tried v20a india for p765 - no luck, drivers are installed ok, i can enter fastboot mode and send commands (reflashed JB xloader an uboot), i rooted the phone and tried to unlock bootloader via terminal emulator - still simple reboot. As described on the threads I waited 30 mins, 1 hr, even 8 hrs before sending adb reboot oem-unlock - no effect
I'm really out of ideas :crying: Maybe my bootloader is permanently locked? Is there a way to find it out?
Since it's possible to enter fastboot is there any other way to unlock the phone or install the custom rom with locked bl?

Try flashing ics kdz, do a factory reset, flash jb europe open see if you can unlock it
I downgraded to v10a ics -> factory reset -> hard reset (to be sure -> flashed v20b europe open .... still oem-unlock results in regular reboot...
I have succeeded after a factory reset and sleeping for one night. You may try to flash EU open v20c and wait with data connected.
I tried that already ... the phone sleeped overnight on v20b and v20c and after i tried to send oem-unlock... nothing happened.
I don't know if it's proper behaviour- after sending adb reboot oem-unlock in the device manager appears TI Board/OMAP4430 only for 1 second and phone reboots normally (just like connecting the phone to usb without battery but TI Board apears only once)
After flashing 10a and before hard reset should I also flash ICS xloader and uboot or do they come with the 10g?
I'm with same problem, but my model is p768. Im still trying to find a solution to unlock bootloader/CWM/Root
I have P769. The same thing, "adb reboot oem-unlock" just reboot the phone, without anything else.
Edit: a few more tries and now I'm unlocked.

The x-loader is not found in the kdz, but the u-boot is.
Try flashing the u boot for ice in fastboot, then flash the 20b kdz.
If this didn't work, reflash the 20b kdz, but when it starts to boot up, turn it off and flash the u-boot from 20b in fastboot and try.
maybe the u-boot is not getting over written. It's easy for a p769 model owner to tell if they are on the 20b u-boot (inverted lg logo), but not for the other models.

You do have the inverted lg logo at boot, right?
You might want to try what I did.
When I was flashing the 20b kdz, I swapped the 11th bin (to root) and the p760.fls (radio file).
I extracted the 20d kdz and renamed the p769.fls to p760.fls
I didn't get root (something went wrong) but I had a network signal and could make calls.
I did make/received a couple of calls while on the 20b.
I think I waited like 4 to 5 hours before trying to unlock.

I have the same problem , what can I do? I waited 30 minutes and also I tried with different versions (spain open)
Up,
Same problem there on my P760
Tried some differents kdz, 20B from my default carrier (SFR), 20B europe open & 20H Europe Open,
With this method http://forum.xda-developers.com/showthread.php?t=2189646, This one too http://forum.xda-developers.com/showthread.php?t=2190326
Actually Rooted & With Artas' recovery 1.5
For me the first few times I try "adb reboot oem-unlock" the phone just reboot. I don't know what to do at first. Worse I have P769 and with the P760 rom on it, the phone is not usable. Then I just leave the phone there and do my own things for a few hours. When I come back, I thought I should try one more time before giving up, it all works out. Maybe I didn't wait long enough with my previous attempt. Anyway I'm done and looking back it was difficult (with my P769 this is true).

Do you think it makes a difference if I root and flash the new radio with cwm, compared to your way where you just replace radio the file?
Also is the radio file exactly named p769.fls and is it in the folder where we replace the 11th bin? Thank you
Same Issue but solved
maybe the 30 minute time is just a rough estimate. I flashed my p765 with p760 v20h and did a hard-reset(because of "com.android.phone stop" issue) and then waited for about 20 minutes with SIM and wifi on, until I turn on the mobile network switch. Then after exactlly 30 minutes I tried but failed. I googled and found this thread. After that I made a second try and worked.
So maybe just remember: 1.insert SIM 2.turn both wifi and mobile network on (not sure which matters) 3.Be patient
it may be that those who are succeeding have a different firmware / ROM version, and / or, their ROM is from a different carrier. i have CWM installed, i'm rooted, and i still cant get into the bootloader to get fastboot to unlock it, nor does this adb oem-unlock method work. fwiw, i'm using v20d TMO USA. i'll post back if i ever figure out how to get the damned fastboot to work...

We have been looking into this a lot. I recommend do try to unlock without know your stuff, you may permanently lock your device.
How about we meet up Tuesday, I'll show you how it's all done. Name the place, I'm not afraid to drive to the Northside, lol.

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

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.

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
Hi people!! I have a BIG PROBLEM, because i live in Argentina, and my L9 it´s called P778g, and have the same specs than the P768, BUT the ROMs of the last don´t work on P778g for nobody in my country (I´m from an hispano parlant forum) and also don´t works the ROMs of P760/P765.
Someone can help my to fix this very big problem? The mobile have v10a ICS, and v20a from the operators of Movistar and Claro.
Is there no way to unlock alternatively, or last, unlocked via fastboot as XPERIA´s phones?

I think you can flash P760 rom on ypu phone. As I know only P760 - Europe Open - V20B or V20C can unlock bootloader. I you want to unlock your phone bootloader your must flash it. Their're some people that follow that thread but cannot unlock bootloader. I don't know why. For me it's work at first attempt.
For your problem, please try
- Turn on your phone, connect usb cable, select LG software mode
- In offline flash program select "DIAG" in Phonemode instead of "Emergency" then follow normal offline flash step.
- Your phone should reboot to S/W mode automatically.
After reboot their may be some software error message, you can ignore it. Some thread said that you should wait for about 30 minutes and have your sim and wifi on may make unlock bootloader success. Please give it a try.

But, i try to put a CWM Backup of the V20B Europe Open, and works on my phone!!!!
At first time i try to unlock the bootloader without succes, but i try a second time However, in my first try on v20B, my computer detect the OMP44...blabla,
Edit: 2 try fails too
@artit i have question, It is possible to find a better method of unlocking as unlocking via fastboot like XPERIA phones?
I was talking with a colleague Argentine was one of the first to buy the P778g just went to the Argentine market, and apparently could safely install the "v20B Open Europe" like any other ROM it existed, but after you break the screen and it changes to a other "identical" phone, the same thing has happened to his.
There may be a possibility that the method is removed to unlock the bootloader and install any ROM in our P778g?

There is no new unlock bootloader for now. I notice that a lot of people have problem unlock their L9 bootloader. May be there is new way to unlock it in near future. Just wait to see it happen, some dev is working on it.

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

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.

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)
Its no my work im just sharing it try this it willl surely work
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 accessType reboot oem-unlock ans the phone will reboot un fastboot mode ! Press volume up and your bootloader is unlocked

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

I was struggling with downgrading etc, because omap drivers didn't work with Windows 8.1, so huge thanks, easiest unlock ever.
