Someone know why not working on every windows?

I have the android sdk installed and the same procedure worked for me without linux.
[LG Optimus 4X HD] laufersteppenwolf:
i honestly don't know :D try it, like i've said, give it a try and report back :)

hmmm, possible? maybe, but this would be extremely slow, cause you've gotta get adb working first and so on. so i'd say it won't work, but not sure.

but some distros have got the ability to install them as a "windows prog", this creates a virtual harddrive where linux can be booted from, so no need for reformatting the hdd just google about it

some users reported that it will not be lost after flashing a kdz. but also here: not sure, cause i haven't tried it myself yet (my BL is now unlocked for about 3h yet :D )
[LG Optimus 4X HD] laufersteppenwolf:
i guess it is driver related... what firmware do you use? german or euro-open?
[LG Optimus 4X HD] roesti91:
This "final" screen I can confirm on my 262-000 from Amazon. I used Windows and http://xdaforums.com/attachment.php?attachmentid=1859693&d=1365149301 for the ADB driver but the same method. It takes like 2sec to do! I installed CWM etc. fine afterwards!! Thank you!

I just get Security Error, any ideas?
[LG Optimus 4X HD] Derjan23:
Don't work with ADEUBK 262 000 :(

I can only unlock with the china 20a.
[LG Optimus 4X HD] nedooo:
This is not universal, seems with latest update LG showed some mercy on German users...rest can feel screwed all over again ;)

F*ck you LG retards :mad: they are only good if Google screws them good, who's your papa :silly:
[LG Optimus 4X HD] pierg75:
On 234 this didn't work with Linux and the leaked 20A.

I might try later to update the phone (GBR) with the official one but I wouldn't hold my breath.
[LG Optimus 4X HD] verlol:
I use euro-open.

If its driver related, which driver is needed?

I only know of the Google USB Driver for the Android Composite ADB Interface.

[LG Optimus 4X HD] DavidXanatos:
when you get " Lg Security error..." is the phone bricked or you just need to pull the battery and reboot and than its fine again?
[LG Optimus 4X HD] happyminti:
The Phone reboots after ~5 secs.
[LG Optimus 4X HD] JAsko_san:
Thanks for the tutorial - but can you explain why is this just working on a Linux OS ? I mean what's the difference between trying to unlock the BL on a Win7/8 OS or a Linux OS ? :confused:

THanks
[LG Optimus 4X HD] RuedasLocas:
Sometimes is semi-bricked, specialy after the "morning-call empty" :)

Don't worry, re-flashing will solve the problem.

[LG Optimus 4X HD] ch3:
On windows - premission denied (ADEUWH), installing Linux now, then will try again.
[LG Optimus 4X HD] pierg75:
In linux the USB devices are much easier to manage than in Windows.

In linux basically a udev rules is enough to get your USB device recognized, whereas in Windows you need a specific driver.

This might point to the fact that the driver is somehow important in the unlocking process, but I guess that with the new update they enabled the unlocking on german devices.

I'm trying now to unlock a 234 phone (Linux is my only OS ;) ) after the update.
[LG Optimus 4X HD] nikosblade:
234 here, i tried to unlock with ubuntu 12.10 via virtualbox. Sadly no success.
[LG Optimus 4X HD] thediksta:
It doesnt look like it works on any OS, can someone please be kind enough to make and post a video tut on unlocking the linux way, everytime i try it i get adb problem, im not a total noob, iv used over 100 different roms on nexus 7 and a500 iconia, i think that lg are really enjoying doing peoples heads in,

how can i flash the correct firmware to change from 234 to 262, i have tryed every different kind from every country i can think of and still get the same dam 234, my phone is unlocked to all carriers and is euro, there is no reason for this to happen, i cant stand this lg OS, i need to unlock bootloader to get away from this crap and use cm10 or pac or aokp, anything other than lg sh*t

Guys who still have problems with unlocking:

Have You tried to rollback to ICS (http://xdaforums.com/showthread.php?t=2179126) and then to flash ANEUBK V20A via kdz flasher in CS_EMERGENCY mode with SIM-Card in the phone?

I think that on the official ANEUBK is other version of bootloader (the unlock menu looks different for example).

And another thing, flashing official ANEUBK on the v20 leak DOESN'T CHANGE THE BOOTLOADER!

So please check it guys and show the results.

if u still can't unlock it, i think that can be the problem, please do what i said and check whether it helps or not ;)
[LG Optimus 4X HD] tiflao:
I flashed the 20A ANEUBK on the 20 leaked version...

This is the error?
[LG Optimus 4X HD] Shuny:
You might be right, as I flashed v20A official on V20A beta.

Didn't you mean "without SIM-Card" instead of "with SIM-Card" ?
[LG Optimus 4X HD] reas0n:
WITH SIM-Card, it may be somethin' like with L9 update. If we don't check, we won't know :D
[LG Optimus 4X HD] laufersteppenwolf:
well, i haven't found working windows drivers.... that's why i was using linux ;) no need to install drivers, simply connecting the phone and the fun can begin :D with every phone

well, i haven't tested it on a VM, i've got linux installed normally (needed for building roms --> much better performance ;) ) maybe a normal installed linux is needed, cause the "commands" are "walking" from linux, over windows to the phone... dunno :o

and for the security error, have you charged your battery to 100% that was also a problem for me ;)

in windows you need 100% correct drivers for device specific things. some things might work over other (e.g. 90% correct) drivers too, but if it gets specific, this won't work, cause the drivers "translate" the command differently.

on linux is no need for drivers or anything. just plug in the device and it will work 100%

maybe i can make a video later, but no promise ;) what do you mean with "adb problem"? please be a bit more specific

and there is no known way to "change" the firmware from 234 to 262 or eur-xxx or any other version...

i was using linux ;) so no need for drivers ;) divers are only needed for windows
[LG Optimus 4X HD] roger321974:

[LG Optimus 4X HD] Shuny:
Didn't work
[LG Optimus 4X HD] verlol:
If found this: http://adbdriver.com/

The program forces windows to use official google usb driver v4.0 for your phone. Installed and works! lg p880 is recognized as samsung phone. Not sure if everything is working as expected.

adb also works, but i am not able to test if unlock works with it

Another way to get the universal adb-driver is to paste the usb vendor id into the SDK\extras\google\usb_driver\android_winusb.inf and install over windows device manager. Think the program above does the same.

I unlocked 234-000, but it was from Netherland market, and after unlock when I flashed JB once again it was EUR-XXX...all this doesn't mean nothing...this is all LG crap...why did they invented semi-unlock...inovative?!?! Mother.......!!!!!!!!!!!!!!!!!!!!
[LG Optimus 4X HD] nikosblade:

[LG Optimus 4X HD] Zeph90:

[LG Optimus 4X HD] reas0n:
I wrote this post today:

And now i've got the another idea:

what about rollback and then flashing v20a but in official way (i mean lg mobile support tool) ? I think that before flashing JB it will be necessary to flash the firmware A***BK/A***WH version, which the phone had in original, without that the update may not work.

You can check it with this:

csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=YOURIMEI

I can't check it by myself, 'cause i'm unlocked :D

I just unlocked my 262-000 German, with Windows 7 and by using "adb reboot-bootloader" and then "fastboot oem unlock". I had problems with the driver for fastboot, but i did download the fastboot driver for LG Nexus 4. After i used the first command, i opend the device manager, rightclick on fastboot and Driver update, used the the second options and selected All devices and the browsed to the extracted driver dir and choosed the .inf file.

I needet to restart the phone, it did make a factory reset before i pluged out the battery :( . But then with the driver installed i wanted to give it a second chance, and tada, unlock.

PS. Sorry for my bad english

[LG Optimus 4X HD] tool_king:
After all, it seems to be a matter of the drivers (or the unnecessary drivers under Linux).
[LG Optimus 4X HD] laufersteppenwolf:
i don't think it's the device itself...

i think that there is somewhere a file, the BL checks for "deciding" being locked or unlockable... as easy as it sounds, all we gotta do is fing that specific file... but i don't know yet why some devices are unlockable and some are not (while running the same firmware).

but i think that using a linux distro is still one of the best choises you can do ;)

[LG Optimus 4X HD] dynam1tedelux:
Everything's fine here now, what did i do:

Flashed V20A_ANEUWH over V10H_ADEUWH (rooted) with KDZ-Tool in CS_EMERGENCY mode ...

Unlocked Bootloader on stock (no root) V20A_ANEUWH Firmware (Device was 262-000) via adb reboot oem-unlock

Rooted with root.bat

Copied CWM and unsecure boot and executed via ADB

Everything went smooth with no single error through all the flashing process.

Device is from amazon germany and was bought in 12/2012.

Thanks for all the helpful guides, in my opinion everything works perfectly so all the guys with unlocking problems: did you doublecheck your usb-connection, drivers, adb-stuff, etc.?
[LG Optimus 4X HD] pescaero:
the phone has to have to be root? before adb reboot oem-unlock?

I've always tried to do after root
[LG Optimus 4X HD] laufersteppenwolf:

step?

that could be a reason, too...

[LG Optimus 4X HD] dynam1tedelux:
No, sorry for that misunderstanding: Phone don't need to be rooted on V10/ICS, i just did that before to make titanium-backup of all the games and apps my girlfriend is using...

But i think its an important thing that the V20A is aNeuwh instead of aDeuwh and the battery needs to be full :)

Good luck guys!

[LG Optimus 4X HD] laufersteppenwolf:
the official procedure from LG is via "adb reboot oem-unlock" ;) "fastboot oem unlock" might just be a side effect ;)

[LG Optimus 4X HD] LamerDuck:
you get past the "security: denied" error, when you need to install fastboot drivers.

they are attached on this post:

http://xdaforums.com/showthread.php?p=38953792

Basically:

1. Connect you phone via USB, open adb, type: adb reboot-bootloader

- your phone will reboot and will stay at the LG logo, just let it be like that for now and go to step 2.

2. a) Download fastboot drivers from nedooo's post and extractem them to your desktop or wherever you like

b) Go to your computer's Device Manager, there you will find "fastboot" with yellow triangle over it. Right clik on fastboot -> update drivers -> browse my computer for driver software -> click on browse and select the extracted folder from step a)

3. We've installed fastboot drivers, all you need to do now is go back to adb and type: fastboot oem unlock

You'll get message on your phone, so use "vol up" and "vol down" keys to select "Unlock" option and "power" button to confirm the selection.

Your screen will go black, wait for 30 seconds and then remove the battery, put it back in and turn on the phone.

[LG Optimus 4X HD] LamerDuck:
do you see the "fastboot" device in your device manager, when your phone reboots?

does it have a yellow triangle?

if it does, then you need to install the fastboot drivers as explained above.

"if your pc says "the newest drivers are already installed", then you did it wrong.

you need to click on "manually select the driver" and in the next step on "select driver from a list on this computer", there you choose the "android_usb.inf" from the extracted zip file.

worked for me, and after that i was able to choose "unlock bootloader" in the next step.

didnt unlock though, hidden menu still says "locked":-/

[LG Optimus 4X HD] RuedasLocas:
Something very wrong here...

And I don't think that provider settings matters for the unlock!

When I unlocked mine (I know that mine is APOLBK...), I installed V20A with LGFlash Tool soo, no data on the phone, I didn't inserted the SIM card or sd-card, nothing... I install the OS, root, unlock it (tooked me a few times untill get it), connect to wifi, deleted un-wanted apps, and only after all that I inserted the SIM card.

I thing that some hardware ID, probably the same that determines if the OS version should be installed as EUR-XXX, 260-XXX, XXX-XXX or other, is the responsable of unlock be or not allowed. And also how people try to unlock (a lot of things can differ, since PC installed programs till drivers) might matters too, giving different results in equal devices.

The worst is that once unlocked, the bootloader can't be locked again soo... Tests are not possible, only attempts from those who still locked :confused:
