2.HKG-XXX

3.yes

4.BLACK

5.CHINA PTT

but a known some AHKGWH (Black) flashed to 230-01 or 262-01 which can not unlock.

i found another difference between unlocked and no unlockable . command line:

C:\> adb shell cat /sys/firmware/fuse/odm_reserved

my already unlocked result:

0x00000000000000000000000000000000000000000000000000000040000000c0

no unlockedables result:

at line 839 of arch\arm\mach-tegra\tegra_odm_fuses.c in v20a kernel source, we can find,

lg modified the source code let the file /sys/firmware/fuse/odm_reserved can be write and burn the fuse !!!

as we all known, fuse is an OTP device, once we set a bit to '1', we can never clear it.

[LG Optimus 4X HD] fire3d:
OopsWare, do you had the leaked Rom installed before and tried to unlock the BL with the leak?

I have the same output on my device (not unlocked)

Another question for those who are unlocked already, from what i have read the unlockable devices have BL Version 1.0? and what version is on the unlocked devices?
[LG Optimus 4X HD] OopsWare:
flash kdz only:

hongkong v10c -> german v20a (leak) -> unlock BL -> hongkong v20b
[LG Optimus 4X HD] fire3d:
Must i do a complete Rollback to HK v10c or only Flashing the HK v10c KDZ and then the German 20a Leak over the top of the HK10c?

Edit: does anyone have a dl link for the german 20a leak? :)

How did you installed official Jelly Bean Open Europe SW?

I was using LG Suite and LG Suite version hacker. I ues kdz file from here. I flashed it on old machine with fresh windows xp.
[LG Optimus 4X HD] DavidXanatos:
did you did that befoure or after the oficial version for swiss phones came out?

what do you get when you enter your IMEI on LG'S page http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=YOUR_IMEI_HERE

For me it seams to want to change my phone form a ASWSWH to a ASWSBK which is supposed to unlockable.

[LG Optimus 4X HD] DavidXanatos:
did you run the command on the new 20a rom or on the old stock rom?

yes- run the command on the new v20a

Tony
[LG Optimus 4X HD] OopsWare:
poweron p880, the avp will boot from internal rom, decrypte bootloader( EBT partition ) and execute it.

the bootloader will load boot image (LNX or SOS partition) , validate the digi-signature then start up android

unlock bootloader means some flag been set, after unlock, bootloader will not check the signature, so we can flash 3rd-party boot-images

the best place to store the flag is fuse, once unlock, nobody can lock it again

if data in odm_reserve is all zero, maybe it has chance to be unlock, but if it burned some bad flags forbid unlock, no one can help i think
[LG Optimus 4X HD] DavidXanatos:
I updated to 20A and it still says all zeros

does it make a difference if I run the terminal as root or not?
[LG Optimus 4X HD] roger321974:
when i type this: adb shell cat /sys/firmware/fuse/odm_reserved

my output result:

that it means i never can unlock the bootloader???
[LG Optimus 4X HD] Newbleeto:
Let's not jump to conclusions. I have never flashed the leak and have the 08 flag set. My phone is a Vodafone branded 268-01 with euro open firmware flashed. I have flashed the update 20a through the official LG tool. I did downgrade it once and had a bad flash, but always with official software.

Making a bootloader locked is bad, making it unlockable would just be mean and serve no practical purpose. I have some trouble believing that.
[LG Optimus 4X HD] roger321974:
goto (with file explorer) /sys/firmware/fuse/ and a lot of files can be opened by selecting with Text Viewer...

[LG Optimus 4X HD] roger321974:
i phoned before one hour with a friend and he told me followed.

he has the same unlockable problem with his free black model. 262-000 ADEUBK with ADEUWH official Firmware. He has for some days give up to unlock. Now he has startet an experiment again and his bootloader going to unlock. His way were now go back to v10a and then flash the Taiwan v20b (this one http://csmgdl.lgmobile.com/swdata/WDLSW/LGP880/ACWTBK/V20b_00/V20B_00.kdz) Version (after every flash factory reset). Then Rootet and then ADB unlock Version. At last he flashed back to official German v20a ADEUWH.

Can someone test and confirm these Procedure? I would test it, but i must go to an birthday party now.

Interesting thing... When downloading Firmware (.dz) with the B2BCheckApp, the dll is different from the files comming with the kdz-files.

I used the B2B dll`s, and flashing in LG Flash Tool starts at 0% and interupted at 82% (App says fail, but device is not bricked...). Using KDZ dll`s starting at 5% or 7% and flashing ends with success.

I also found in LG Flashtool 1.5.10.1120 B2B dll´s shown PID and IMEI from device, but KDZ dll´s shown "0"...

Its based on the region your phone was made for, theres been a few ideas to change it, one is rather dangerous involving flashing an unlocked BL via fastboot, the other involves sniffing usb traffic for useful information, hopefully something comes of one of these

Thank you so much for your awnser [MENTION=306612]non[/MENTION]4 .I was reading more pages about it and I have seen that you developers are getting some trouble with it...

That's somehow good to read. Another option throwed away. :D

This guy is spot on and I think LG should really sit up and listen to him. Lg have really let the UK customers down so much over the years. I totally agree that we are all peed off with LG.

the only way they've let us down so far is by not releasing the official firmware for uk users yet. it's only after they do this and we STILL can't unlock that we will have truly been let down.

Why are carriers so concerned about unlocking 4Xs, yet the far more popular Galaxy S 3 has been unlockable since day one?

[LG Optimus 4X HD] arnookie:
LG just seem to be letting the UK down so much. The UK is always one of the last countries to get official updates, same with optimus 2x waited forever for ics and ended up buying 4x before it ever came nearly a full year later. But I sure hope LG don't let the UK down for unlock.

Atleast we have some hope with official uk update when and if it comes. Just not holding my breath with my lack of faith in LG.

All you need to do is make a "TRUE" EUR-XXX out of the 232-000 (and 232-alike), BEFORE you can unlock. But that probably requires more than the EUR-XXX/NEU firmwares. Maybe its a setting which is not normally flashed, even in ermergency mode. Or one which cannot be changed by a flash at all. (like the IMEI) :crying:

so you could try

1. change IMEI

2. flash 20a

3. change IMEI back

ofc this will only work if its really related to the IMEI thats stored at the place, where this command changes it.

but its worth a try i guess

[LG Optimus 4X HD] roesti91:
How about 1. LGflash downgrade to 10a EUR-XXX 2. KDZ reflash to same 10a EUR-XXX 3. Check if you Factory version has changed from 232-000 to EUR-XXX in the hidden menu on 10a? If true, upgrade from there to 20a ...

Can one flash the firmware from Poland (v10a) which also will let you unlock? There is tons of other country firmwares which will allow for unlock, there are all different sizes, maybe one of them will also reset the "Factory Version" to their correct country code?

it depends only on the installed firmware, and this relates to the IMEI.
