What about Fastboot driver? My first try was a bust because the fastboot driver wasn't properly installed.

Anyway, this might look and sound stupid, but I went to adb recovery mode (phone connected to PC, hold POWER + Vol -) and at that point my PC started installing some drivers.

When it had done installing, I checked the device manager and found out Fastboot was shown with yellow acclamation mark as the driver wasn't properly installed. I simply right click the device and update the driver manually.

Right after that, the phone showed something like ADB Ready or Now Ready (or something like that I forgot) and I typed the command fastboot oem-unlock after which it offered me if I wanted to unlock the bootloader or not.

I included the fastboot driver as well in case you need it.
[LG Optimus 4X HD] :
Thank you a million for your important tip, really.:angel:

I will be trying out tomorrow cus it is 2:03Am where i am now but i'm already tasting success.:cyclops:

yes i was suspecting poor fastboot support too.

[LG Optimus 4X HD] future81:
yes i think official unlock method is sim related - fastboot works without sim (maybe needs you to don't use sim in somecases)
[LG Optimus 4X HD] VictoriaCoffey:
I had the same problem, it was definitely proximity sensor, even before Jelly Bean, but JB made it worse. Dial 3845#*880# -> Device Test -> All Auto Test Menu Full -> ALC / Proximity Test. All you need to do is calibrate it and you are all set :)
[LG Optimus 4X HD] Dexter_nlb:
if its all simcard related, maybe selling danish simcards with a small amount on, will be the solution.

im sure it can be done for €25-30 or so..

hello guys

i flashed the JB kdz 2 days ago and it worked very well, but i'm noticing some annoying lag now

success.

but i don't know if it was because i installed the stuff. here's what i've done.

I typed adb reboot-bootloader, LG logo appears

fastboot oem unlock, <waiting for device> then nothingness as usual.

after that instead of pulling the cable,

i "ctrl + c"ed out

next thing i know on the phone its Factory reset for first bootloader unlock

then Sucess!

Pull battery and boot.

now how do i make everything looks normal in case i need to send in for warranty?
[LG Optimus 4X HD] nikosblade:
You cant. :P There is no way so far to lock the phone again.
[LG Optimus 4X HD] :
now that calls for a really huge GODDAMMIT

even if i re-flash? we didn't have unlocked BL in ICS but we have it now in JB right?

so what the *u*k?
[LG Optimus 4X HD] nikosblade:
Yeah, there is no way so far to relock your bootloader even if you flash it. Right you couldnt unlock bootloader in ics.
[LG Optimus 4X HD] Flying_Bear:
there are reports that people have managed to re-lock thier bootloader by flashing not trough kdz, but trough lg flashtool, the one that sniffs sockets or whatever, so it might work for you :good:

So far

I have found out the camera shutter sound silences itself if you have the phone in vibrate/silent mode, think in ICS it made a sound all the time.

Enjoying the new pull down notifications and the slider for screen brightness

When getting text messages a little bubble pops up in the sceen corner

Google Now

Real Racing seems smoother

No Qslide

LG Gearbox only works in power saver now so you cant set the core and CPU speed

but this file is the only difference between a locked and an unlocked one for them... but before we try it, we need to know what mmcblk0p5 is ;)
[LG Optimus 4X HD] @non4:
Everything I search points to boot.img ;)

Sent from my rooted P880

nope, boot.img gets extracted to mmcblk0p9 ;)

see the updater-script from the CM nightlies: ;)

package_extract_file("boot.img", "/dev/block/mmcblk0p9");
[LG Optimus 4X HD] @non4:
Well that's just from google, obviously they're related because all that came up was boot img and boot unlock stuff. Its hard to find explanations of these sorts of files. Well actually in some phones it seems to be recovery, in others it seems to be related to boot from what ive read. Perhaps in our case the method would be adb push to mmcblk0p9, as I think these are all just partitions of a filesystem type and devs can somewhat choose what goes where if that makes sense

Sent from my rooted P880
[LG Optimus 4X HD] laufersteppenwolf:
yes, there are big differences about which partition is for what (boot, recovery, system,....) but we need to find out where the L7 users push this file to, and then we can look further...

Lol, I told LG that we got our own unlock and they sent this:

"You may have been disappointed at the delay but meanwhile we were seeking for a proper method on how to deal with bootloader unlock.

We became aware of many developers’ requests and opinions on the issue, and we were internally discussing a method to support them.

Please understand that there has been a communication overhead that could have been perceived as too long.

From now on, we will try harder to find and execute a solution that can satisfy customers/developers, and carriers alike."

[LG Optimus 4X HD] :
for each product companies have to spend alot of time discussing with marketeers, engineers, designer, programmers on possibilities of modification. They also have to talk with carriers etc.

really especially for an important thing like unlocking bootloaders alot of parties will get involved in the discussion after enough momentum is gathered from the public. Discussion probably includes benefits for the company, implications (incld technically) etc.

it has a few minor other improvevemtns but if you dont care about those 4.03 is clearly the better choice. it uses less ram and is just as smooth and has to dump ram less often and therfore needs less cpu time to load a app.

After days of reading and research on the problem of unable to update my 4X using aby methods ihad almost given up. I tried every process mentioned on this forum and tried across 3 different PC / Laptops as advised by several members that MAY be the current PC / Laptop isnt "loaded" enough. So i got out my 3 yr old Chinese netbook running the lowest version of Win 7. and guess what? I just ran the LG SUPPORT TOOL and it detected the new upgrade in no time and took about 2 hrs to download and install the update. and now my phone is running the supper smooth JB 4.1.2

I am very happy with the update. its like a new phone all together. The only "issue" i am facing is abnormal battery drain. in no time the phone looses 5-6% battery. I have NO major apps running. NO FB, Twitter etc.

Just go for hard reset.

Keep your phone on charger although it is 100% charged for about 45 mints or 1 hour.

Use the task manager to stop useless Services.

Unplug it in after unlocking the phone screen.

Same kernel version 3.1.10 of course.
