But how will you change the IMEI?

I think I have not seen anyone on the P880 has could change the IMEI
[LG Optimus 4X HD] cupidstunt:
Ah well, just trying to think outside the box!
[LG Optimus 4X HD] roger321974:
i think imei change is illegal

edit: found a tool, but i think is not for free and need an external box ... http://octopusbox.com/eng/news/details/296

[LG Optimus 4X HD] Apoena:
I don't know, that's why I asked if it's possible ;)

It probably is so people don't clone other people's phone. That's why I thought of that guy, because he would be "cloning" his own phone and he didn't have to share his IMEI with anyone else.

This would just be to check if the possibility to unlock your bootloader is really only IMEI dependent. Once we find out WHAT that trigger is we can start to think of a way to get around it.

After step 3 "adb reboot oem-unlock"

Phone reboot and I get only charging battery animation on display (battery is fully charged) and phone will turn off.

Any tips ? :confused:
[LG Optimus 4X HD] @non4:
In roms that do this the only way is the fastboot method, in my case however I select unlock and nothing happens

[LG Optimus 4X HD] GizModio:
Changing the IMEI could possibly get you into trouble.

Follow this at your own risk!

I recommend using a program called Hyper terminal, it comes with Windows XP and is easily downloadable to Windows 7.

You would also need to change the phones USB connection mode to CP USB (3845#*880# > Port settings > CP USB)

1. Start hyperterminal, in COM settings select same port like in device manager -> LGE mobile USB Serial Port, 115200 (Important)

2. Type AT if response is not OK, change port number

3. Type at%imei, it should display your current IMEI

4. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your original IMEI number (It is very important to make sure you put the commas between each number!!)

5. Reset

I recommend checking afterwards by typing *#06# in to your dialer, afterwards put the usb mode back to AP USB
[LG Optimus 4X HD] Newbleeto:
Where did you get this information?
[LG Optimus 4X HD] Emin3ms:
I tried the different methods:

Windows 7 64bit : adb drivers ok, fastboot drivers ok, installed CT_HsPhone_General_Drivers.

Battery fully charged -> 'adb reboot oem-unlock' I get LG security error.

-> 'adb reboot bootloader' -> 'fastboot oem unlock' -> tiny text in the top of the screen (2 lines: -Don't unlock -Unlock it) -> choose unlock it -> get "Bootloader is now unlocked" in cmd.exe -> wait 30sec or more -> remove battery -> get "FAILED <too many links>" in cmd -> hidden dialer menu still says Lock.

-> http://xdaforums.com/showpost.php?p=40440711&postcount=489 I tried but "FAILED" at step 5 (fastboot oem unlock) or same result as precedent method if i skip step 4.

-> http://xdaforums.com/showpost.php?p=40437346&postcount=4183 I don't understand this post (not bilingual) if someone could explain me..

I didn't try with Linux, I think its the last solution

Well, I got my phone in December through phones4u as T-Mobile doesn't sell it - How's the carrier going to lock it then?

I have a o2 sim and have tried flashing with that in - no good

On my T-Mobile login says I can upgrade my handset in June ( I guess coz I kept my contract with them)- if this isn't sorted by then then bye bye LG forever!!

Another unlucky user reporting LOCKED 232-10. My phone is unbranded with a 20a JB EU rooted android. I tried all methods and failed. Just cannot understand why I always get a status: "Bootloader is unlocked now" (in CMD) but in hidden menu it still says LOCK. :confused:
[LG Optimus 4X HD] Shuny:
I'm pretty sure it's bootloader dependant. Anyone who flashed the beta V20A are now stuck with the beta bootloader, which can't be unlock.

Has someone flashed the V20A beta and then managed to unlock their device ?
[LG Optimus 4X HD] KuroShinigami:
FYI: downgrading to v10 rewrites bootloader...
[LG Optimus 4X HD] Shuny:
Does it ? Have anyone managed to prove this ?

And still, did anyone succeed at unlocking his bootloader after trying the V20A beta version ?
[LG Optimus 4X HD] KuroShinigami:
Try reading posts above and/or similar themes...
[LG Optimus 4X HD] tulen_kobi:
So if I understand correctly, there almost no chance to unlock bootloader of phone from carrier. Because I guess they will never alow to do so.

I am considering of selling my phone because I don't want to get stuck on lg firmware.
[LG Optimus 4X HD] Newbleeto:
Just because LG won't allow us to unlock our phones doesn't mean they will remain locked forever. There is some type of security in place to stop branded phones from being unlocked, that is for sure. I have faith in the developer community, tougher nuts have been cracked.
[LG Optimus 4X HD] Agamemmnon:
Believe me, i have made a downgrade to v10 over 5x without success, no chance.

I have often read that people have after and on the V20A beta unlocking their Phone.

This is my last hope, otherwise I'm going to sell the phone, because without custom ROM`s I do not want it.
[LG Optimus 4X HD] roger321974:
sell phone is the best permission denied to LG. i call it [User_Security]LG Phone Denied.
[LG Optimus 4X HD] DavidXanatos:
did you try to install CM or somethign else, to test if it is really still locked?

I have a 232-10 as well and just updated it, now I'm not sure if to try to unlock it if it fails no gain but all data gone.

I have flashed the EUR V10h ICS again using the LGflashtool , although software doesn't show EUR-XXX it shows LG -P880 -V10h-Nov-19-2012 - I'm in the UK and on T-Mobile, but this phone isn't available through T-Mobile in UK as was bought through phones4u.

Was wondering if anyway to get the v10h to display as eur-open and then try putting the eur-open version of official 20A on?

If not is there any point point in trying to flash this anymore?
[LG Optimus 4X HD] @non4:
There's no way, flash is auto determined in v20x by your region. I've tried flashtool and kdz updater and different country roms and I always get 234-000

Arrrrgghhhhh Updated

I had a thought - I used the software that comes with the phone - set country to Poland and then chose the phone model - said latest software was 20a.

Went into recovery and entered the imei from this thread

http://xdaforums.com/showpost.php?p=38920820&postcount=268

It started to download software and I noticed it was 579MB - so JB!! I'm in UK so latest should have been v10h -

When it downloaded it was shows as the 262-000 version and it successfully updated, but in phone info still showing as 234-000 - Checking logs on the pc it had my IMEI number not the one I entered on recovery - if we could only edit the recovery process so it used the other imei

Damn!!!
[LG Optimus 4X HD] scarfaceq:
I would like to but I cannot even install CWM so that I could flash CM. I tried to install recovery via ROM Manager and it doesn't work. (When I try to enter it just says LGE security error, something about boot.img)

Just for your information guys, i just wrote another email to lg, asking about a list of unlockable firmwares and, most important, what this error "permission denied" should mean and why it occurs.

hopefully we'll get an answer about this error, and maybe we're able then to get around it.

Just as a procedure says i am doing steps exactly as they are written on the first page , and after writing in adb adb oem-unlock my phone reboots itself and on the upper right corner for 1 sec is red text that unlock is forbiddedn , and after that my phone starts to charge
[LG Optimus 4X HD] laufersteppenwolf:
for how long are you on v20? is your battery fully charged?
[LG Optimus 4X HD] teddyxfire:
Nope, nothing works :/ But there's one strange thing: If I press "vol up" to continue with the unlock process - while the USB cable is still plugged in - all I get is this red "Download Mode" message and nothing happens.

On the other hand, if I unplug the USB cable, new message shows saying "Running Factory Reset for the first bootloader unlock :: please wait...", but again, nothing happens after that.

Do you think that I should open a new thread regarding this problem?
[LG Optimus 4X HD] laufersteppenwolf:

[LG Optimus 4X HD] peppethustra:
If you have the "Running Factory Reset for the first bootloader unlock :: please wait..." message, wait 30 seconds and try to reboot your device (by long pressing power, or removing battery); then, check bootloader unlock from hidden menu, for me it said" unlock" after that.

---------- Post added at 04:12 PM ---------- Previous post was at 04:03 PM ----------

Well, you will gain the chance to better customise your device: flash files, tools, kernels, custom recoveries and custom roms directly from fastboot or via adb, since from when developers will start to work on them (at the moment, we have some kinda tools, but not so much yet, primarily because LG has to release some sources about it's own kernel and rom, which are necessary to start developing in a very proper way).

[LG Optimus 4X HD] JAsko_san:
Dude, U've read my mind :D I just wanted to ask you guys if someone knows what the "Permission denied" text means :) I'm eager to read the reply from LG :) I hope that they will give us a step by step explanation on how to unlock our BL on every known firmware there is!

it would be lame that LG makes a phone with few firmewares - and one off those U can unlock and some of them you can't - btw it's the same phone - what's the point of this ???

I also downloaded the official v20a - EuroOpen version, and when I flashed it on my phone I've got "232-10" :/ on the other hand, a friend of mine flashes the same kdz on his phone and he gets the euro-open_xxx version (on this version you can unlock the BL - all the other version - no, no, no - hell no xD ) - that's strange?!

Btw thanks laugersteppenwolf for your help :) and of course for those emails that you've send to LG :D
[LG Optimus 4X HD] lcd4linux:
I've tried almost every method to unlock the bootloader and none of them worked. But after waiting for couple of hours, like described below, the unlock was possible! I think the most important thing is wait for couple of hours.
[LG Optimus 4X HD] teddyxfire:
I had the same problem few hours ago so I used different method to unlock the bootloader and it worked perfectly.

Check this thread and watch the video tutorial, it's short: http://xdaforums.com/showthread.php?t=2180497

Also, pay attention to the post number #17 by nedooo, he attached fastboot drivers in his post.

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 extract 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.

Credits go to nbock97 and nedooo, you can use this method if the official method doesn't work for you, in our case official method couldn't get past the first red message ("Download mode") for some reason, probably because of drivers.
[LG Optimus 4X HD] rhapsodize4452:
Forgive me for asking this, I know unlocking the bootlocker gives us the access to install CWM, CM10 etc. but apart from a root access do we need an unlocked bootloader for our stock ROM, any advantages like improved battery life, performance optimisation etc. or some other benefits???
[LG Optimus 4X HD] Agamemmnon:
I have the 232-10 too and after 3 Days still no Chance!
[LG Optimus 4X HD] teddyxfire:
Nope, having root means that we can get special permissions from Android system and having unlocked bootloader means that we can install whatever we want - wherever we want. Root and unlocked bootloader won't improve your phone's battery life, but you'll have the ability to install custom ROMs, kernels, every imaginable app etc. Proper kernel coding is responsible for battery life, so we need to wait for LG to release kernel's source code. After that, developers will start with custom modifications based on original kernel...and you know the rest of the story :)

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, 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 charaxter string.

Thanks for trying.
