So, here I was just sitting, thinking about our beautiful L9's and how they have come a long way, when I started thinking about the current method to unlock the p769 boot loader. As most of you know the current method has you flash a p760 and p765 kdz onto our p769 which messes up our touchscreen. This is when I got to thinking. What about restoring to a custom tailor made p760 nandroid backup in CWM with the correct touch firmware already in place? This way we would have the p760 firmware needed to unlock the boot loader, AND our touchscreens would not be messed up . Anyone think this is possible?
In short:
1. Flash nandroid backup from p760 (with p769 touch firmware) via CWM
2. wait 30 min
3. unlock boot loader as you normally would on a p760 or p765
4. restore to p769 nandroid of jb or ics with unlocked boot loader for custom roms

I was under the impression that the touch screen issue is in the uboot file. And that file is what unlocks our bootloader.

Oh is it? then couldnt you just flash the uboot alone? instead of the whole kdz? The main goal is to find a simpler more user friendly way ha

I see. That may be possible. But I am not sure if you can flash a new uboot without unlocked uboot.

You can flash a new uboot without an unlocked uboot, you just have to be rooted (dd if/of), or even unrooted (fastboot via omap). As for being able to unlock using that method, I'm still testing that out on my backup P769 with no luck so far.

i plugged my phone in LG software mode and waited for 34 minutes and then gave the adb reboot oem-unlock command and the phone just restarted as normal without booting into fastboot or the BL unlock screen!
did i do something wrong?

What unlock BL thread did you use? It's possible after issue "adb reboot oem-unlock" and your phone just normal reboot. Many people has that problem. Let me guess it about new board hardware version. But some people keep trying to unlock and they success in third or fourth try.

Hello i have just purchased this phone and i want to unlock the bootloader and install CWM and then Cyanogenmod but im finding it is very difficult to do so.. I have a few questions.. i have found some info on here but it says from tmobile 10g..which i am not.http://forum.xda-developers.com/showthread.php?t=2277639. Why is it so hard to do this and why after so much time has an easy fast method not been posted anywhere.It pisses me off they lock this thing up with all this built in bloat and make this so hard for users.. we are paying for the phones-therefore we should have 100 percent control over how they are used..
1. Is there any easier less risky way to unlock my bootloader and install cwm/cyanogenmod than this clusterfack way
(http://forum.xda-developers.com/showthread.php?t=2277639) for noobs ha
2. I rooted and flashed Cwm but i cannot get into it either with key combo or adb reboot recovery(brings me to android with open stomach screen, thats it..and i assume if i try to flash a zip like cyanogenmod IF I DID GET IN WITH A LOCKED bootloader it wouldnt work or id get security error)
i have busybox installed and phone is fully rooted..I need to avoid bricking and security errors at all costs
3.i need detailed step by step instructions for lg l9 p769 21d (locked bootloader) willing to offer a bit of cash to anyone who can help me successfully Unlock my Bootloader without any device brickage or security errors.
Update: Itried installing the artas test version on cwm with his installer and I now can get into cwm..the stable one wasn'tworking..
So now Ihave recovery just bbootloader locked preventing me from flashing any new ROMs...sighh
Update..I used cwm recovery installer by artas and I now can get into cwm
Device info
lg l9 p769 21d (android 4.1.2)
build number JZO54K
1.) Flash to 10G. T-Mobile doesn't matter, it still works with Wind. I've used Wind ROMs on my T-Mobile.
2.) That is the only way to unlock it, I'm sorry. Some conspiratist was trying to unlock it using a different method, but he rage quit when someone made fun of his website (lol).
3.) Really, it just takes luck. I haven't got it yet. But I try daily and it takes about 20 mins of work and 30-40 mins of waiting, so it's worth it. About to give up though lol.
LOL, I just realized you used numbers too. My numbers here don't correspond to your questions in that order. What a coincidence!

OK flash from 21d wind too T-Mobile 10g... Then I need to flash to Europe open 20b for 760...unlock the boot loader with mirrored image and messed up touch screen..then gain root..install cwm and fix the touch screen..
ARE YOU SURE I CANT GO FROM 21d to EUROPE 20b? Unlock bootloader and root and then Be done with it?And if so , Why not?
Anyone here unlocked boot loader of 769? BTW there is no working link to Europe open 20b kdz..I've been looking everywhere for an hour all links and downloads are broken/not working..anyone have the Europe open 20b for this process?
edit think i found the europe 20b
People say there's problems with it lol.. I haven't unlocked yet sadly. It's an annoying process and I feel that some devices can't be unlocked no matter what

Well it can be unlocked..but its a pain..day 1 and lg support tool will not install w admin priv/compatibility mode for xp sp 2/3.I'm on win 7
I take it this is why it won't flash the kdz and crashes the kdz installer..also shows phone not found in emergency mode but it is found in diag mode..what's with that?
Lol.. I'll try again tomorrow.. But I think I need to on a diff PC cause I've tried everything and it just gets stuck(lg support tool) at like 10 percent install..
What is the reason for going from 10g to 20b Europe and then back to 10g
Why not just stay on 20b fix the touchscreen etc and leave it..?
What issues if any would arise from flashing 20b Europe from 21d wind?
The unlock boot loader for.noobs 769 has files for SD including radio.zip..
Does the radio not work after flashing 20b Europe open? And if so how can I flash a zip on Europe 20b and unlock the boot loader without first installing radio.zip through a cwm?

Go to the General section, and find the sticky (at the top) of the thread with the stock KDZ's by cmahendra. Find the ICS KDZ for P769, and download it.

Hey there,
the bootloader of my G5 (h850) is unlocked.
TWRP installed, root not yet (but i could)
For some unknown reason my wireless does not work anymore so i wanted to update my android to V10D (europe).
After i will install custom roms but at first i wanted to know if i have a hardware problem.
Due to the TWRP an OTA update is not possible .
Now my question:
Can i install V10D via LGUP with an unlocked bootloader?
Or do I have previously perform a relock ?
thanks in advice
you can with unlocked
just go ahead
