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 say factory reset, flash the V20B kdz, enable usb debugging and leave the phone on for several hours before trying to unlock. try the kdz found here, i used the first one http://forum.xda-developers.com/showpost.php?p=43104055&postcount=9
Hello man ! I just tray to flash this KDZ and wait about 23-26 hours but the phone just reboots normally...So what can i do ???
Well the only help I can give you now is to try the P765 V20A India kdz. I'm all out of options, sorry.

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.

there is no other method to unlock it, some people reported that it helps to have wifi connection before trying to unlock the bootloader

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
Hello , I need your help , I have a Moto Maxx ( xt1225 ) was using the RR 5.1.1 Rom , just not liking it and doing Downgrade for kit kat , but I knew I could not have the First two commands rom because the device would go into brick , through a tutorial to follow here on the site managed to put it in the fastboot screen but he says that with the locked bootloader and does not accept nor a command that I try to send it recognizes the mfastboot devices command but the error trying to send the rom commands or do the bootloader unlock again , wanted to know if my case is hopeless , if I really have to send switch the device board
I wish I could send a picture of how the device is but I am unable to post links
Hai I have been using Moto e 1st gen for 3 years. I have left my mobile fully charged in a cupboard before 2 months. I found it and charged for a lot of time and it showed me the bootlooder and 0 charging screen. My mobile is rooted and run a 5.1 CyanogenMod os.
I figured it have drained and booted the fastboot menu and charged for a while. It showed that "device is locked . Status code :0". I managed to flash the stock ROM but it didn't because of battery low.
After 3 hours the battey turned green and I was able to run the 'fastboot devices' command. I tried flashing the stock ROM but it's only flashing the partition,Moto boot,logo. Rest of the of the files return "preflash validation failed" .
I think unlocking if the only thing left but I'm getting 'could not get unlock data'... Plz help me and I might have accidentally locked the bootloader during the stock ROM flashing "mfastboot OEM lock begin"
I'm totally new here. If you can help me plz write in detail...:good:
