Works Great!

Works on 234-000! Wasnt expecting anything positive lol.

FREEEEEEDDDOOOOMMM!!!!!:victory::victory:

Everyone should know about this.
[LG Optimus 4X HD] Stanley-:
Didnt work

I tried manual

cat /sys/firmware/fuse/odm_reserved >/data/local/tmp/odm_reserved

but i get: not a directory :(
[LG Optimus 4X HD] @lbert:
If you reboot after updating the system file your update is over written, the unlock persists fine on my 234-000 UK phone.

But once the file is overwritten you reboot and you're unlocked with no need for adb or fastboot commands.

I used the CWM install that Dexter posted and now can use power and down volume to enter CWM and do a nandroid backup.

I suggest anyone who gets errors echoing the updated file reroot or make sure you su root.
[LG Optimus 4X HD] Apoena:
FREEEEEEDDOOOOOOOOMM!!!!!!

Here's to LG :p

MOD EDIT: Please do not post such pictures

Sorry about the OT.... but I'm happy and silly today :p
[LG Optimus 4X HD] laufersteppenwolf:
hmm, it's working for me... (except the pushing, didn't try that 'cause i'm already unlocked ;) )

just a litte mistake in your command it's not:

cat /sys/firmware/fuse/odm_reserved >/data/local/tmp/odm_reserved

but

cat /sys/firmware/fuse/odm_reserved > /data/local/tmp/odm_reserved

;)
[LG Optimus 4X HD] lukas77:
I had SE Xperia Arc and there was no problem to unlock and lock bootloader how many times you wish, so I'm not so sure about this 'fuse' and only one modify.
[LG Optimus 4X HD] laufersteppenwolf:
this is a completely other procedure to unlock the bootloaders ;) you can't compare them ;)
[LG Optimus 4X HD] Stanley-:
Finally unlocked :D
[LG Optimus 4X HD] _MiseryMachine_:
232-10 unlocked now

I had troubles editing the odm_reserved file, i then opened it in script manager and edited it there... it works, says unlocked now

:victory:
[LG Optimus 4X HD] faisal222:
my odm_reserved file is empty..wat i m doing wrong ?:(
[LG Optimus 4X HD] mario.gacv:
Success!

I finally achieved to unlock my branded optimus4x :cool:

716-10

Carrier: Claro

Country: Perú

BL: Unlocked!

BTW, I tried every automated method and they didn't work so I manually edited odm_reserved and pushed it back with Android Terminal Emulator app.

Thank you all!
[LG Optimus 4X HD] Nooby305:
Okay Noob Question , I used the script file , it typed some commands and then getting me to " Welcome To Lg Fastboot Mode :) " And Some Guide Notes , And At The End " Now Ready ! " !!!!!!!!

Does That Mean The Process Of Unlocking The BL IS Done ?? And If NOt How Can i Check If It's Locked Or Unlocked ?????????????

pls ADVICE
[LG Optimus 4X HD] roy8846:
Help!!

I ran script (with root) using script manager.

I then Installed CWM via Rom manager and reboot

I now have ERROR boot image signature and a bootloop Someone help please??
[LG Optimus 4X HD] fire3d:
not unlocked, i know scripts are often much easier, i suggest to do the whole process manually

check if you can get into Bootloader, there you can fix it manually with the ADB comands,

or reflash the stock recovery via fastboot
[LG Optimus 4X HD] scarfaceq:
I just tried this method with the provided script and I still get: LGE Security: Unlock permission denied. I got V20a EU rooted android. I wrote to LG yesterday and they said that If I installed a leaked version (which I did) before the official one, this could be the problem and that I should take phone to LG customer service so that they could "reset" it or something... Could this maybe be the problem? :/
[LG Optimus 4X HD] Agamemmnon:
Yeeeees, one Million Thanks! Worked on 232-10
[LG Optimus 4X HD] roy8846:
I can only access s/w upgrade screen I think??

Is fastboot possible or need to go stock?
[LG Optimus 4X HD] fire3d:
that's the same that they have wrote to me, ignore it, unlock it :)

i had the same, leak before and the other unlock methods don't work for me, my BL is unlocked now
[LG Optimus 4X HD] fire3d:
you can use booth, adb or fastboot, depends on which one you can enter
[LG Optimus 4X HD] Konstantine33:
262-000 deu version UNLOCKED with this way! thanks!!!!!
[LG Optimus 4X HD] mario.gacv:
I also installed the leaked firmware, then installed official OPEN-EUR and my Optimus4X is branded and non EU,

With this method I managed to Unlock my bootloader so it should work for everybody.
[LG Optimus 4X HD] roy8846:
I have managed to get phone on by holding power and vol + then when phone switches off automatically , next boot is fine.

Can you help on getting stock recovery installed please :)

Googling 4X HD Stock recovery brings me no joy :(
[LG Optimus 4X HD] atomanti74:
It's works on 216-30 AHUNBK.

Thanks
[LG Optimus 4X HD] igorstoja83:
I am on EUR-xxx and i unlock mu bootloader long time ago,and I am very glad that you are all sucsses with this.Now grab the CM... Cheers :fingers-crossed:
[LG Optimus 4X HD] Shuny:
262-000 unlocked using the procedure. Even if it seems weird to me ... isn't echo /data/... supposed to like cat /data/... ?

Anyway it wrote something random in the odm_reserved (0x000000000000000fdfffffcafffffffdfefeffed or something like that) but it worked so I don't really care. Thanks for the procedure :)
[LG Optimus 4X HD] cupidstunt:
Try doing it again manually as it hasn't worked.

Loads of us had the leak installed and this has worked for most of us.
[LG Optimus 4X HD] JAsko_san:
Holy crap....this was so easy - why nobody else hasn't come up with this :P :D just kidding - thanks OP for this metod and Derjan23 for playing around with this :) and finding actually a working way on how to unlock our Optimus 4X HD :) amazing guys

Thanks a lot :)

Now....someone said something about Cyanogenmod :D juhuuuuuuu :)

Btw one question, does the BL stays unlocked, even if I flash another rom, like cyanogenmod, or MIUI ( when it get's available for 4X ) ????

I mean - does it reset it self after we flash another rom over the official v20a rom ???

Just for the record, I have the hutchinson version, aka -> 232-10 firmware :)
[LG Optimus 4X HD] Trigun:
Just curious, did you use ClockworkMOD ROM Manager to install CWM 6.0.3.1 and CM 10.1 after you unlocked the bootloader or did you do it all manually? I noted in the Google+ post that we should be able to do so. Not a my machine where I can run through this yet.
[LG Optimus 4X HD] JAsko_san:
I've just installed CWM recovery via the app itself - and I can even download the latest CM nightly trough it - so yes - you can flash the CM10.1 via the app from the play store :)
[LG Optimus 4X HD] thecresta:
Regarding re-locking the phone:

If you unlock the bootloader and start up in S/W Upgrade mode you'll see a message in the top left corner saying the bootloader is unlocked.

I've just rolled back to ICS and that message no long appears.

I'm just about to flash JB again to see if the bootloader status is still unlocked or if it's re-locked itself. I'll update this post with the result.

UPDATE:

Nope, still Unlocked. Even changed the odm_reserved file back to default before downgrading.

Looks like we're stuck with an unlocked bootloader.

At least you can stop the message appearing if you need to return it to a store, I suppose... :/
[LG Optimus 4X HD] elfen.lied:
I just did all the steps and rebooted into bootloader with: adb reboot bootloader and now I'm stuck on LG logo with "Now Ready!" being shown in the top left corner. Any idea on what to do now and is it unlocked at all?
[LG Optimus 4X HD] roy8846:
NOOB GUIDE *Must Be Rooted First*

1 - Download Android Terminal Emulator on phone, open it and enter.....

su root

cat /sys/firmware/fuse/odm_reserved >/data/local/tmp/odm_reserved

2 - after that edit the file odm_reserved loctated here: /data/local/tmp/ (ES file explorer with root permissions and system write enabled)

change the line that it reflects this one: 0x000000000000000000000000000000000000000000000000 00000040000000c8

3 - save the changes, back to the terminal enter:

echo /data/local/tmp/odm_reserved >/sys/firmware/fuse/odm_reserved

4 - Download the tool here http://xdaforums.com/showthread.php?t=2230934

5 - Make sure USB Debugging is enabled in settings and open tool that you downloaded (Install the drivers by pressing 1 if you don't have them already)

6 - Press 2 (Unlock Bootloaders) , once finished Power down and turn phone back on

7 - Press 4 then when finished press 6 (Flash Unsecure Boot and Flash CWM)

Done (Tested By Me :D ) 234 000 v20a UK Unbranded

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

Also anyone cannot write to /tmp try this

Delete tmp folder

then

su root

cat /sys/firmware/fuse/odm_reserved>/data/local/tmp/

Goto local/ and edit tmp file using file editor / text editor to

0x000000000000000000000000000000000000000000000000 00000040000000c8

change name of tmp file to odm_reserved

then

echo /data/local/odm_reserved >/sys/firmware/fuse/odm_reserved
[LG Optimus 4X HD] elfen.lied:
Just did it :D Thanks a lot. Worked like a charm
[LG Optimus 4X HD] Fladder72:
I´ve edited the script of laufersteppenwolf for BL unlock.

Hope it´s noob-friendly enough... ;)
[LG Optimus 4X HD] rtunner:
Works fine, BL unlocked, but my SD was erased...

edit.: now it's not recognizing the sd card.
[LG Optimus 4X HD] DavidXanatos:
I tryed the script and now my bootloader says unlocked.

but i also got: 0x000000000000000000000000000000000000fdffffffcafffffffdfffefeffed

insteas of

0x000000000000000000000000000000000000000000000000 00000040000000c8

I think the bug the the space in the string

it should have been:

0x00000000000000000000000000000000000000000000000000000040000000c8
[LG Optimus 4X HD] roy8846:
If you mean the new odm_reserved is random its supposed to be like that ;)
[LG Optimus 4X HD] DavidXanatos:
ahhh in that case, coool...

Al run as expected

I already have clockwork in it and I'm backuping everything.

Next step will be to try the new CM.

I'm really sooo heppy.

I believe the solution was really simple just write some bits on Hi in the fuses, but due to the one time nature of the experiment the most didn't have the balls to risk it. a BIG BIG BIG thanks to the founder of the solution you really Have balls of steal.
[LG Optimus 4X HD] Dexter_nlb:
good to see research paid off.

we had this one closing in early on in another thread, but i believe no one ever considered to exchange values with a locked device, and this could have been out in the open much earlier. anyways good job!!!

[LG Optimus 4X HD] exFAT:
Hey guys,

Could someone with a locked bootloader but with root try this command to unlock their bootloader:

echo 1234567890 > /sys/firmware/fuse/odm_reserved

Based on my findings,

http://xdaforums.com/showthread.php?p=40597604

in the previous step, only one command unlocked the bootloader. The rest were unnecessary. The command is

echo /data/local/tmp/odm_reserved > /sys/firmware/fuse/odm_reserved

Contrary to popular belief, it does not write the contents (aka unlock code) of /data/local/tmp/odm_reserved to /sys/firmware/fuse/odm_reserved, but instead writes the text string "/data/local/tmp/odm_reserved"

But it works. The likely reason is detailed in my link above.

From what I observed, I think the last 10 digits of /sys/firmware/fuse/odm_reserved determine the unlock state.

My above command is a test for my hypothesis, you can replace the 1234567890 with any other 10 character string.

Thanks for trying.
[LG Optimus 4X HD] DavidXanatos:
[MENTION=5019740]exFAT[/MENTION]

I Think you are right "echo" is just a command to write text on screen.

I think the BL checks one or two fuses if they are Hi and if so its unlocked for good.

So of cause writing the wrong string that just don't set the right fuse wont help.

What would also be cool to test is if one write 0x000000000000000000000000000000000000FFFFFFFFFFFF FFFFFFFFFFFFFFFF

setting all bits to high if the bootloader still remains unlocked or if there is a bit that coudl relock it again,

but this time for ever.

I installed CWM 6.0.3.1 Touch manually just by visiting the Clockworkmod website and pushed the image through using the fastboot command. :good:

Using the app should work too! :)
[LG Optimus 4X HD] Trigun:
Did the following

adb reboot bootloader

fastboot devices <-- just checking it was there

fastboot flash recovery recovery-clockwork-touch-6.0.3.1-p880.img

but then it claims the bootloader is locked even though the hidden menu says different.

I can install using the ROM manager but not with fastboot. Odd. I guess I'll take what I can get.

Nevermind. Didn't finish what I was doing. Still needed to perform the oem unlock.

Still says bootloader is locked when trying to flash touch recovery but hidden menu says unlocked. not sure what is going on but since I can use rom manager I'll stick with that. Next I'll try installing CM.

Update: When I run adb reboot oem-unlock I get dumped into fastboot and I am then able to flash recovery.

[LG Optimus 4X HD] laufersteppenwolf:
for all 4x HD bootloaders ;)
[LG Optimus 4X HD] @non4:
What it means is any optimus 4x, because LG were able to restrict it to phones from euro open regions only. This gets around that. No unlock method is universal for all phones, every phones security is different

Hi, guys.

I have such problem:

1 . Software P880 ADEUWH 20A (262-000) version

2 . Unlocked Bootloader this method.

3 . Now not correctly the approximation sensor works, in case of calls the screen and about 30 seconds completely dies away keys and a touchscreen aren't active. As in case of the response to a call.

In what there can be a problem and how it is possible to decide it?

And still, whether it is possible to return LOCKED Bootloader?

Forgive for my English. Thanks.
[LG Optimus 4X HD] tool_king:
Just go to hidden menu (dial 3845#*880#), device test, all auto test menu full, alc proximity test and calibrate your device.
[LG Optimus 4X HD] Raza46:
Will it still work...

I rooted, and installede CWM first. And obviously ran in to the problem, of the security error. However, is it still possible to use this method with CWM already, and will it then boot in to recovery once the steps have been executed?

Sorry, if I sound a bit stupid, have just started trying to join these forums and understand what awesome work you guys do!

[LG Optimus 4X HD] tool_king:
Yes, works for 232-10 as well.
[LG Optimus 4X HD] Subhajitdas298:
Can you please tell me exact steps you did?
[LG Optimus 4X HD] meditec:
Works fine

It works fine. Better than every every Tool :)

TIP: use sshdroid and connect the phone from your PC. That is even better than Terminalemulator or something else.

:good:
[LG Optimus 4X HD] TechnoBraker:
Here are the steps..

Install all reqd. drivers (eq. fastboot) and adb. Drivers usually install automatically when you connect your device to the pc for the first time.

Install your fav. terminal app from the Play Store. (i used this)

Open terminal app and type the following:

su root
cat /sys/firmware/fuse/odm_reserved > /data/local/tmp/odm_reserved

Edit the file odm_reserved located here: /data/local/tmp/ using any root explorer app from Play Store.

Change the content to:

0x000000000000000000000000000000000000000000000000 00000040000000c8

Save changes.

In the terminal app enter:

echo /data/local/tmp/odm_reserved >/sys/firmware/fuse/odm_reserved

Connect your phone to pc. (Charging Mode - USB Debugging enabled)

Open command prompt (win+R -> cmd -> enter!) and goto location where you installed adb. (You'll find adb.exe there)

Type the following:

adb reboot bootloader
fastboot oem unlock

Your phone will reboot. Press Vol Down, then Power Button from the phone to unlock. (i waited 45 sec and rebooted

the phone)

You have unlocked bootloader. Confirm from hidden menu. Dial 3845#*880# :highfive:

Follow these steps to install CWM touch recovery 6.0.3.1 (d/l and execute the commands from the folder which contains the downloaded .img file)

[*] Done! :good: :D

I have had V20A 232.10 3At Austria.Now I have CM10.1

I have rooted and bootloader unlocked.CWM recovery installed.CM 10.1 RC2 installed.

Everything works just Reboot bootloader is not working.

I have often tried.It gets stuck on the LG logo.

Why have no bootloader?

Has an idea? Thanks

[LG Optimus 4X HD] Fladder72:
You can flash recovery and kernel images via fastboot or boot custom kernel to test before flashing...

But on some devices "reboot bootloder" dosn't work (Bootloader don't work as "unlocked"...)

In that case you have to get into LG-Bootloader-Mode via "reboot oem-unlock" to flash kernel images etc. ;)
[LG Optimus 4X HD] chrisch91:
Hm.. I think my bootloader is "real" open, because i can flash it via cwm :)
[LG Optimus 4X HD] yellow rabbit:
how

how do you edit the file located in /data/local/tmp?:confused:
[LG Optimus 4X HD] @non4:
Use es file explorer in root mode.

To the OP, all commands should be cat but the last one is echo, although this works it blows many fuses and has nothing to do with the file in data/local. You should update it to the correct method with "cat /data/local/tmp/odm_reserved > /sys/firmware/fuse/odm_reserved ;)

[LG Optimus 4X HD] ryanrod:
Absolutely worked! Thanks for pointing this out. There were a couple of steps that were unclear to me while reading this tutorial. You cleared up that first step.

After the first step, I used ES File Explorer in root mode to browse to the odm_reserved file. I then opened it with ES Note Editor and changed only the end of the number after the 4 by adding the seven zeros and c8. Then saved the file. Like this: 0x000000000000000000000000000000000000000000000000 00000040000000c8

Its also true in the next terminal step. Essentially put a space between the less than "<" and the slash "/":

not this

echo /data/local/tmp/odm_reserved >/sys/firmware/fuse/odm_reserved[CODE]

but this
[CODE]echo /data/local/tmp/odm_reserved > /sys/firmware/fuse/odm_reserved[CODE]

I followed the rest of the steps exactly and it worked. My phone's software version is a P88020b-HKG-XXX as shown in the thumbnail:
