Cheers for the reply!

Still not working for me. How did you get to 20A you're on. Did you update through LG PC Suite or KDZ updater, and if through the latter which KDZ did you use?

Also have you ever encountered the [LGE_Security] unlock permission denied error?

Sorry to be a pest!

P.S.

Could this be something to do with MLT (as noone seems 100% about what it's function is) as I've always disabled it in the hidden menu after flashing?
[LG Optimus 4X HD] lukas77:
I've got same error on 234-000 but later I will try to flash kdz again and restore factory settings. I have root and many frozen apps and maybe this is the problem.
[LG Optimus 4X HD] WillySonicteam:
My phone the version v10h to v20a is updated with the "LGMobile Support tool".

The battery to 100% and wait more than 2 hours to proced to unlock.
[LG Optimus 4X HD] Timbol.:
Why all talk that you need 100% battery??

No reason for this!

Sorry for my bad english :D

you need to double click on all the steps from step 0 to step 5

this pushes extra files to your phone which im sure is the reason why it has made are (all) bootloaders unlockable

Thanks again, I just assumed not to bother with the batch files as they were skydevs method for keeping root before upgrading. Will give it a shot when I'm back home.

cheers again
[LG Optimus 4X HD] laufersteppenwolf:
what the hell should this **** do? it's simply Skydev's script to keep root while upgrading from ICS to JB. and a 5th bat file, that says "step 4", even tho it's called step5.bat. AND it includes only one command, which doesn't even make sense...

@rem Transient Root (ICS v10x -> JB v20x) by Skydev

adb fastboot oem unlock

thats not working for all ... lg says its working ... thats random procedure from lg... also be carefully and wait ... i wait now a week for my second phone... first phone unlocked, but why not second? i think lg knows more about... i have now no interested solve this problem (have 36 hours work to solve it)... lg is the problem to solve his hijacking bootloader... hijacked by imei by lg ...
[LG Optimus 4X HD] JustChris20:
Myth!!! Don´t waste your time!!!

If "adb reboot oem-unlock" failed in a security error, you will not unlock the bootloader in any ways, so don´t waste your time.

MYTH!!!:

--------------

1. not the correct adb driver

if your lg p880 reboot after this command you already have a correct adb driver, changing the driver not necessary!

2. not the correct fastboot driver

you don´t need the fastboot driver here!

3. you need a special Euro Version to unlock the device

if you installed 20a thats in any way correct, because it´s all the same file, bit for bit the same!

4. Unlock with linux will be success

if unlocking in windows fails, linux will also fail it doesn´t change anything!

5. unlock with chinese bootloader

just an emulation, so you will not really unlock it here!

6. Changing IMEI will help

no succes here too!

7. Another sim card will unlock your phone

no, you may change dozens of sim cards but you will fail...

So what is it, why can someone unlock, another with the same phone can´t

I asked the lg support today and here is the german answer: its so sad so i will not translate this...

...wieso funktioniert der unlock beim P880 / 20a Euro mit adb reboot oem-unlock nicht bei allen Geräten, wurden hier unterschiedliche Chips verbaut?

Mobiltelefon-Support (CN): Dazu liegen uns allgemein keine Informationen vor. Je nach Produktionscharge ist dies jedoch denkbar.
[LG Optimus 4X HD] skryptus:
I haven't seen anyone say this, but I have seen many people saying that, if you install the same Euro-Open version on a German and UK LG 4X, it will update to a "different version of the software". It's still JB, and it's still release 20A, but instead of being identified with EUR-XXX it will be identified as 262-000 (for Germany) and 234-000 (UK). This for the sim-free phones.

For the sim-locked (i.e. locked to T-Mobile, Vodafone, Orange, etc.) phones, most don't seem to be unlockable, as they also don't update to EUR-XXX.

I'm still not convinced about the Linux method's effectiveness. But you can't say it doesn't change anything, as the drivers are different. I believe it's important that people keep trying in both OSes (if they can, of course), as it might make a difference.

As for the rest of the post, I generally aggree with you, and many of those tried-and-failed solutions shouldn't be repeated as often as they are...
[LG Optimus 4X HD] laufersteppenwolf:
I've got some good news for german unbranded users :)

i just recieved an email from LG again, but this time from the dev. team itself :D

so all unbranded german phones are unlockable, too. in the same way like euro open.

so generelly i guess all unbranded versions should be unlockable.

but due to the IMEI check, i guess the phone has to be originally unbranded and not just having flashed an unbranded firmware...
[LG Optimus 4X HD] @non4:
So anyway to debrand? I remember some variants of desire z had to be debranded to use some stuff, if I remember correctly though it was really complex procedure though :thumbdown::eek:

Sent from my rooted P880
[LG Optimus 4X HD] laufersteppenwolf:
hmm, i don't think so... unless you can change your IMEI to an unbranded one...
[LG Optimus 4X HD] SturmGhost:
And how did you change the IMEI?

Actually there is no working methode to do this. Maybe ther is a methode with the LG SmartFlashTool, because this tool can erase the whole CP (which contains the IMEI) but you will need a CP.bin and a AP.bin. Maybe we get this with the SourceCode. I don't know.
[LG Optimus 4X HD] @non4:
Not sure IMEI should be messed with actually, phone thieves could benefit from this information

Sent from my rooted P880
[LG Optimus 4X HD] SturmGhost:
Maybe... But maybe the only way to unlock branded devices. After unlocking you should recover you old IMEI.
[LG Optimus 4X HD] @non4:
True, hopefully we can bypass it by other means, perhaps adb sideload is the key as it allowed root

[LG Optimus 4X HD] fire3d:
trust me, if we know it, we will post it ...... actually i think we stuck here......

i hate LG for this, i love this phone but i hate LG for this Bootloader-Unlock-Lottery ......
[LG Optimus 4X HD] Agamemmnon:
It is not Lottery, it is the IMEI.

If you have a unbranded Phone and the Update for your Country is out or you have a EURxxx it is unlockable.

I received an email from LG Support Switzerland, because i have a ASWSBK and SV:232-10.

When the Update for Switzerland is out, then i can unlock the Bootloader, not previously!
[LG Optimus 4X HD] Emin3ms:
That's cool but I got the official update and unbranded phone but still no way to unlock it :/

PS : now I dont have 'unlock permission denied' but just a reboot
[LG Optimus 4X HD] friartuckme:
when flashing a call is made between the flash program and your phone - probably like an at+ command which then would read imei or version, ive noticed it in the many log files i have from when ive flashed,it might be possible for someone to make something with the offline flash method to trick it, good luck

my lg was a sim free phone so wasnt tied to any network (23400) but wasnt able to unlock so its not only phones tied to networks,i can understand a little the issue that they have with providers but cannot see why the country your from is an issue,

[LG Optimus 4X HD] friartuckme:
sorry for the big quote but chris you are 1000000% wrong about the chinese kdz method. you may ask how i know, its because i was on 23400(not unlockable) and flashed the chinese kdz then managed to erase my bootloader and basically bricking my phone...

So how did you obtain unlock?

On Linux it would be easier to get a traffic dump but on windows this seems to be the only way.

I will try to get a dump next time I'll reinstall the phone (when the official UK kdz with be out).

I also flashed the chinese kdz, tried all the facts and unlocked without success so i know what i write, its not possible...

I have not yet tried unlocking my device and have been reading unlocking stories since the first JB leak.

As far as I can understand it is still uncertain why some devices are unlocked while others are not with the same firmware.

Can someone who could not unlock his device, flash the official firmware with LG PC Suite Version Hacker and LG PC Suite and try unlocking afterwards?

[LG Optimus 4X HD] fire3d:
i have a unbranded device, the official update for my country/device is also out, but i cant unlock .....
[LG Optimus 4X HD] thediksta:
i have explained before but and got abuse,

all i can say is how i did it, first of all i always had a security error on adb reboot oem-unlock....

i then turned the phone on and turned wifi off (coz official instructions from lg say connect to real nerwork, and assumed this is what they mean) and plugged into wall charger and left it for 2 hours,

i then connected my phone to my pc

i then went into my adb i got from this thread on page 6

i then ran the five steps(bat files) but the last one did not work so opened new adb from the same adb folder leaving the other still open

and typed adb reboot oem-unlock

my phone came up with a new menu about the unlocking and wiping process and then a flashed new recovery , and my phone is now unlocked with a working clockworkmod recovery

im not sure why this worked, mayby it was the busybox files that got pushed to my phone in this process, mayby it was leaving the phone on for 2 hours and the battery saying 100%

i dont know

all i know is it worked and i am happy
[LG Optimus 4X HD] cupidstunt:
I tried exactly the same to no avail. I wonder what's changed, did you disable mlt or amend the telephony database?

Also which carrier are you with, I'm with T-Mobile
[LG Optimus 4X HD] thediksta:
no i didnt change anything

im always switching between GiffGaff and 3 because both give me different things when im in other areas but i had my 3 sim in the phone at time of unlock with a good reception and a H in the top right corner

the official instructions say to connect to real network so is this what they mean?

Boot loader unlock UK

Not sure how helpful this is but I emailed LG (김영환(Sean Kim) <younghwan1.kim@lge.com>; on behalf of; opensource-mc@ge.com)

About the BootUnlock situation in the Uk, I received a reply.

Not sure what they meant by the bit about visiting my local service centre, dont think LG have service centres all over the UK.

Dear ************

Thank you for your interest about our mobile phone.

“We received your request on LG Open Source Code Distribution site (]h**p://opensource.lge.com).

This site is just for providing source codes of FOSS(Free and Open Source Software) we have used in our product.”

Could give us more detailed information about your phone? for example, operator or open.

Supporting bootloader unlock is only for Open not branded one.

If you are using open one, then please visit local customer service center to flash official rom.

Leaked version of rom can’t support boot loader unlock.

We hope this information will help you.

Thank you.

Sincerely yours,

LGE MC Company Open Source Code Distribution Center

I have just written an email to LG regarding boot loader lock status for every device, i have also specifically asked about 234-000.

I have mentioned the boot loader lock methods and how they're not working for us, i have also asked if the device in unlock-able, how would we go about doing it.

Just need to wait for a reply... Shouldn't be too long! :rolleyes:
[LG Optimus 4X HD] future81:
anyway they press on using official version and i think official update method that's why they talked about service center

or maybe they wanna check why that happens lol - so for AGBRBK 234-00 that couldn't unlock it should wait official update and retry

and can any ADEUBK/ADEUWH report if they could only do it after official update?
[LG Optimus 4X HD] thediksta:
i do see and agree with your point, but running those bat files definitly pushes busybox files to the device, im just wondering why, i know its something to do keeping root, and on the second to last command it makes device reboot before, so running those files are having a direct affect on it before finally unlocking, (remember that last bat file doesnt seem to make sence) so at this point open another adb path(from that same folder) and typed adb reboot oem-unlock,... no point in doing it from fastboot coz even now im unlocked, i still cant flash a newer recovery untill iv done adb reboot oem-unlock everytime before a flash

i just noticed what you said, does that mean you are not using official update? it has been released, it WILL NOT work with leaked version, only the euro will
[LG Optimus 4X HD] @non4:
How would you have to do it every time before a flash? This is not htcdev unlock. Please explain more I had trouble understanding your post, if bootloader is indeed unlockable on 234-000 with this method I want to know how it was done. Can we see some proof?
