Still locked in hidden menu. It stays at the LG Logo for a while and then it shuts down and the loading animation appears(Just plugging in Phone while turned off)
[LG Optimus 4X HD] pierg75:
I heard quite a lot about these fuses, but never saw a doc about it.

So I searched a bit and found this:

http://http.download.nvidia.com/tegra-public-appnotes/tegra-boot-flow.html

" Fuses; factory-programmable read-only data embedded into the SoC."

It doesn't look like we can ever overwrite these.
[LG Optimus 4X HD] laufersteppenwolf:
they can be written once, and then .... finish yourself :p :D

so flashing the leak might have been a bad idea for some guys ih here....
[LG Optimus 4X HD] pierg75:
"Factory programmable"... That means you need special machines to set a fuse or antifuse.

IMHO if there's a bit flipped around is not in a fuse.
[LG Optimus 4X HD] cupidstunt:
I'm confident the security error is nothing permanent, as many of the people who have unlocked initially had the error also. Only time will tell though!
[LG Optimus 4X HD] laufersteppenwolf:
no, definitely not. i got the security error too, the first time, but later it worked.

this was all about flashing the leak ;)
[LG Optimus 4X HD] KuroShinigami:
Some posts earlier someone tried different kdz and from that data bootloader could be relocked by flashing different firmware (which contanes different bootloader)... From this I assume lock/unlock state is stored in bootloader itself (or somewhere else in device memory but not in bios/fuses)

And fuses are ROM that is been set once chip is produced as far as I know, so leaked firmware can't change them.
[LG Optimus 4X HD] flickyamom:
It stays at performing factory reset for first bootloader unlock after i disconnected the phone from the pc... still for a very long time. When I rebooted, no factory reset was done.
[LG Optimus 4X HD] domieatworld:
I flashed the austrian firmware yesterday and today I tried to unlock the bootloader, but I get the same as you...

I was on the europe open firmware and got the sercurity error....before I was on the austria/hutchison firmware...
[LG Optimus 4X HD] tobixdev:
that seems kinda wierd.. Have you mailed your provider yet ?
[LG Optimus 4X HD] domieatworld:
yes, for 2min ;)

by the way. LG has released the 20a source :)
[LG Optimus 4X HD] tobixdev:
which provider do you have ?

i will do it in the evening :)
[LG Optimus 4X HD] domieatworld:
I have "three" (3drei)
[LG Optimus 4X HD] tobixdev:
mee too

could you pm me what they answered ?

i heared that you could debrand your phone with nvflash.

is that possible ?
[LG Optimus 4X HD] GizModio:
Still no luck!

So i've tried nearly everything possible.

I've downgraded and then upgraded, ive left my phone on for over 12 hours with Mobile data enabled, all the drivers are installed correctly. I've even dropped down to using ".BAT" files and still no luck. I've tried way over 30 times.

There's not anything i could be missing?

Im getting very close to giving up, selling the phone and getting an Optimus G
[LG Optimus 4X HD] laufersteppenwolf:
yes, it was possible, but only on some leaks, becuase the BL unlock was sometimes only emulated, and not "real"

and yes, it is possible to write them, but just once
[LG Optimus 4X HD] cupidstunt:
Only thing I can think of now is to wait until the official firmware is released, although UK users seem to have been forgotten about!
[LG Optimus 4X HD] fire3d:
There was a Rumor or a message from LG about the unlock and the Leaked Firmware, can't remember where i have read this, if i remember it right the message told us that, if we try

to unlock the BL with the leak it can be happen that the BL goes in a unlockable state and this cant be undone .....

but i got a message from LG that i have posted already here: http://xdaforums.com/showpost.php?p=40338674&postcount=155

You haven't got the path to the ADB folder in your environment settings.

Best best is to CD to the ADB directory and run the command direct from there.

You need to write "adb reboot oem-unlock". The phone will reboot for it self.

and now?
[LG Optimus 4X HD] RuedasLocas:
Sorry but, my mistake...

Following what I have done, the right command is

"fastboot oem unlock"

After so many things I start to have some doubts.

Its not a process that we can try because, after unlocked we can't repeat it, the bootloader remains unlocked.

If you want to give a try, download what I use to unlock, here:

http://www.4shared.com/rar/HFf4newq/LGO4X-UNLOCK-BOOTLOADER.html

Instructions are inside

---------- Post added at 12:05 PM ---------- Previous post was at 12:00 PM ----------

When you said that you didn't changed the .dll, I don't know

what you really want to say...

The .dll to flash the V10x is "X3_2008_v0.0.6.9.dll"

The .dll to flash the V20x is "X3_v0.0.7.4.dll"
[LG Optimus 4X HD] tiflao:

How long is the unlocking process supposed to take? I pressed vol+ when it asked me, got the message "Running factory reset for the first bootloader unlock :: please wait..." and it has been like that for 10 min already.
[LG Optimus 4X HD] phynix5800:
So if you previously had the leaked 20A installed, you should downgrade to 10H prior to try to unlock right? Can the 20A final be downgraded like the leak?

EDIT: Never mind just did it, gonna try to unlock in a minute :D.

[LG Optimus 4X HD] phynix5800:
Thx, I realized that I would have to wait some time prior to doing the unlock by now. I tried 3 times (leaving the device on for only a few minutes) and after issuing the command, the phone would just boot to the "battery charging" screen, without instructions on how to unlock. Guess this is normal if you don't wait an appropriate time?
[LG Optimus 4X HD] profyler:
Did you unlock with euro open or german KDZ?

when you conect the phone with usb, should be debug mode on? what type of usb conection? pc suite, mtp etc...
[LG Optimus 4X HD] phynix5800:
Euro open and the German 20A are exactly the same files, so it doesn't matter. USB debugging has to be on, because you are going to work with ADB. Type of USB connection doesn't matter AFAIK.
[LG Optimus 4X HD] profyler:
thank you.

does the phone need to be rooted too?
[LG Optimus 4X HD] phynix5800:
I'm pretty sure it doesn't.
[LG Optimus 4X HD] ilan_75:
sure it doesn't. Mine was not and now is unlock.

where can i find the adb driver since the comand comes from this folder? anyone with a link?
[LG Optimus 4X HD] GizModio:
So would that be where im going wrong? I rooted the phone everytime before i tried the Unlock?

Thats hope really. I would like anything to work!
[LG Optimus 4X HD] cupidstunt:
No mate, it doesn't make a difference.
[LG Optimus 4X HD] laufersteppenwolf:
i flashed the euro-open version, because the german one wasn't out at that time ;)

and it also shouldn't matter in what mode you are, as long sa you've got usb-debugging turned on.

FYI, i was in LG software mode ;)
[LG Optimus 4X HD] profyler:
thanks, but where can i download the adb driver? does the adb have to be on the desktop so that the command sees the adb folder on desktop?

get this file: http://www.uploadtak.com/images/j794_root.rar (for adb)

extract it, open the folder where you extracted the archive, open an command prompt and change to that directory (e.g. c:\root)

or on w7/w8 right click with shift pressed into the opened folder and select Open Command Window Here ..... now you can use adb

[LG Optimus 4X HD] laufersteppenwolf:
well, this is not an official guide... it's a short tut for guys, knowing what they're doing... 'cause if you know what you're doing, you can understand the tut completely...

and as a side note: if someone doesn't understand it, he/she should think if he/she really wants to unlock the bootloader IMO
[LG Optimus 4X HD] RuedasLocas:
Only now I gave myself the trouble of take a look at the guide... I found the step 1 and 2 stupid... and the lack of drivers I can't call it

stupid because I don't remember if I use the LG drivers or "CT_HsPhone_General_Drivers"... step 6-2 showldn't even exist.

Please follow below directions to unlock bootloader.

1. Turn on the phone with SIM card, and wait for connection to the real network.

(the network need to meet the BL to convince it to loose verginity...)

2. Wait for couple of hours.

(BL is not sure and need a couple of hours to think better , bla la la...)

3. Connect your handset to local PC with USB cable.

4. Enter "adb reboot oem-unlock" in DOS command window.

5. Reboot handset and you can see the bootloader unlock guide on your phone.

6-1. If you press volume up key, handset is bootloader unlock status.

You can download custom image using fastboot command.

6-2 If you press power on key, user doesnot accept unlock bootlaoder and handset normally power on.

(after soo much trouble, specially waiting for the step 1 and 2, wondering why the phone is not recognized as it should

or what's happening cause I have no idea!!!... I just choose not to unlock the BL :eek: )

:) :) :) :) :) :)
[LG Optimus 4X HD] laufersteppenwolf:

now everyone should understand the procedure ;)

why the dev profis here have no solution for the bootloader? post an copied manuell is easy, but for 50 percent of the people dont work, because LG has his fingers in there or LG have make mistakes.

the guys who have bootloader unlocked and have skill in android systems can search for a solution for the 50 percent persons. i think we can stop the experiment to unlock bootloader for all the people who havent unlock.

don't know whats now happened, normally i test new ideas with the official method, now i dont get any

erros or such ..... fastboot now says that the bootloader is already unlocked o.O hidden menu shows LOCK

fastboot getvar all gives me :

but flashing CWM gives a security error when i try to enter the recovery .....

*sigh*
[LG Optimus 4X HD] future81:
Because its the only remaining unlock thread I would suggest to change title to official unlock bootloader discussion and include other unlock method and gather info like

1- Installed kdz - flash method - the code you Have in factory version - did you had that code back in ICS and Official version for your IMEI

2- Used Method detailed fastboot or official in steps and the result (success/error mention it)

3- what SIM was in phone during this and how long it was in - if no sim was in mention it

4- WIFI?

5- Mobile data?

6- Previously Installed leaks?

7- Drivers names(fast boot) in device manger and if it has yellow exclamation mark or installed properly

8- Those who had errors first and then success should mention any different steps they made

I would suggest for those have official JB update to try lg flash tool method because its the method mentioned in service manual and maybe can reset whatever prevent official procedure from working and we have 2 members got emails from LG direct them to send phone to service centre to get their

Unlock so I can't imagine another way they will use

I also suggest for those who hadn't official update to either wait for it or stick to fastboot method or if they can try sim from other country

Anyway thread should be oriented to well diagnose the problem from each aspect possible

[LG Optimus 4X HD] tulen_kobi:
Exactly the same problem on ATMCBK, bootloader version 230.
[LG Optimus 4X HD] tool_king:
You should just ask your carrier. It isn't a LG thing, as the v20a Euro Open isn't really different from the 232-10 firmware.
[LG Optimus 4X HD] Agamemmnon:
Yes, you right it is the same

Switzerland Version MD5 b471179c5bddb4f49dac051f87fa6423

German Version MD5 b471179c5bddb4f49dac051f87fa6423

Euro Version MD5 b471179c5bddb4f49dac051f87fa6423

I've been chatting today with LG Support because of the bootloader in 232-10, and they say that it is IMEI dependent.

They have forwarded it to korea, and they hope for an update, bla bla bla....
[LG Optimus 4X HD] skryptus:
Sure, the FW LG releases might not be different, but as has been said, the IMEI seems to be having a say in who gets to unlock the bootloader the easy way and who doesn't. And I don't think the carrier had anything to do with the way the FW is reacting to the IMEI. So they won't be much help.

But to be clear, the people with carrier phones would be the ones with the worst luck for unlocking the bootloader. In their case, there's a legitimate reason for LG to make sure it stays locked (regardless of how much we might dislike that reason).
[LG Optimus 4X HD] Agamemmnon:
Unfortunately it seems to be so:rolleyes:
[LG Optimus 4X HD] @non4:
Nobody at all knows how to force the flashtool to assume your phone is eur-xxx? Its determined during the flash, surely this is easier than trying to bypass the security, if I had coding knowledge I would try it in a second

[LG Optimus 4X HD] tool_king:
What "legitimate reason" shall this be? First of all, it is my decision, what exactly I want to do with my property. Even if I put my device in my ...., it's not the carriers problem. As long as I agree that there shall no longer be any firmware-related warranty, it's definitely not he carrier's problem, if I unlock the bootloader.
[LG Optimus 4X HD] Agamemmnon:
Sure it is our decision, but what can we do?

LG says it's imei or carrier dependent your carrier says it is due to LG, and we are the stupids.
[LG Optimus 4X HD] flickyamom:
YES!!!

UNLOCKED! on ESA-XXX! I followed everything in the guide but I tried something different. I downloaded this: http://www.4shared.com/rar/HFf4newq/LGO4X-UNLOCK-BOOTLOADER.html , then installed the driver before hitting volume up in the bootloader unlock screen. The installing is instantaneous, so it seems like nothing was installed. Main thing that made me think it was the driver was because I tried to do the procedure multiple times without success, so I thought of this. Never knew it'll work. Try it! It may work for you as well.
[LG Optimus 4X HD] cupidstunt:
just out of interest, how many people have registered their phone with LG?

I've just done this and they ask you for your IMEI No. and was wondering if this might be a reason why some can't unlock
[LG Optimus 4X HD] skryptus:
When I say "the people with carrier phones", I mean the people who bought their phones through a carrier, like from Vodafone, Orange, etc. In those cases, LG's client is the carrier, not you. You're the carrier's client.

Also, you should remember that, regardless of their duties to the client, LG runs a business. That business depends on their relationship with the carriers (in many countries, one of the largest avenues of cellphone distribution is through carrier-contracts). And you might not care about that, or think that it's unfair to penalize us for something that's not our fault, but it's not very realistic expecting for them to alienate the carriers just to make a minority of users happy (I hope you realize not everyone wants to install Custom ROMs, I'd say the bulk of smartphone buyers will probably keep their phone stock).

Also keep in mind, phones are usually sold as-is. Your rights are to the expected workings of the telephone. The bootloader is sold locked. It's not your right to have the bootloader unlocked, it's just something that would be handy.

And hey, I'm on your boat - I'm thinking to buy a 4X from Germany, and getting second thoughts due to the bootloader unlocking issue. I'd really like to be able to install CM mods in the future, and maybe even have them carry me into Android 5.0. But I'm fully aware it won't be my right to demand that my bootloader be unlockable.
[LG Optimus 4X HD] The_0ne:
What are the advantages of registering the phone?
[LG Optimus 4X HD] Newbleeto:
Who cares about politics, business or their reasons. That's all well and good, but this is xda developers, and most of us are here because we believe in an open environment and that we should be able to own our devices and do with them as we please.

So let's complain, petition and work to unlock the bootloaders regardless of region. The more free the more developers we'll get.

A hack or work around can't be that hard, if I had the time and know-how I'd be all over it!
[LG Optimus 4X HD] tool_king:
I never said that we have the right to get the bootloader unlocked. That's not the point, The point is, that it's not he carriers problem, if we get unlocked bootloaders, as long as there is no disadvantage concerning warranty for them.

Finally, not the carriers are buying and paying the devices, but the users, so LG would be wise to act like this.

Last but not least, nobody is forced to unlock its bootloader. Nobody is forced to flashg custom roms. But the big difference between iOS and Android is the aspect of freedom for the users, isn't it?
[LG Optimus 4X HD] cupidstunt:
for warranty reasons mainly, but if the ability to unlock is imei related, just thought it may help
[LG Optimus 4X HD] skryptus:
There are disadvantages for them. Their concern isn't so much warranty-related as it is what you can do with a bootloader-unlocked phone. For instance, you can install firmware that exploits the network or causes it to malfunction.

In some cases, the sim-lock function seems to be related to the bootloader, so from that point, it might also be a concern of theirs.

If you buy a carrier phone, the carrier is LG's retail medium. They can't alienate them anymore than they can alienate Best Buy or Amazon.

You're mixing things. This big difference is regarding the OS, not the ability to install other kernels. With LG's stock android you still have the freedom for users to adapt their phone to their needs.

And sure, we want even more freedom and the ability to install OS versions that we think are better suited to our needs. As do the iOS users who jailbreak their phones.

To go back on-topic, I think the pursuit of the unlocked bootloader is valid, and am counting on it. I'm just saying that people that bought the LG 4X through a carrier should lower their expectations. I'm not telling anyone to stop trying, far from it. (After all, it's your phone!)

[LG Optimus 4X HD] Apoena:
Is there a way to change your IMEI? There was a guy around here who had two phones, one locked and one unlocked... maybe we could have him downgrade his locked phone to 10a or something like that (to make sure it's back to its original factory state), change his IMEI to the same as his unlocked phone, and try to flash 20a on top... if he can unlock we at least know exactly what makes our phones locked/unlocked
