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.

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 think you may need uboot and xloader from an unlockable device, aequitas3, i just pm'd you.
Bump... Any new findings on this?
Okay, so I restored animusFL's deodexed stock backup, and then I flashed the CWM recovery V20F update, but now my phone is stuck at the T-Mobile logo, and even if I try to flash a KDZ with S/W upgrade mode it doesn't work because I was previously on JB. I'm unable to access my homescreen to activate LG Software Mode. Can somebody please provide me with a simple hotfix? Please I need this fixed before night lol.
EDIT: I'm unable to access my Locked Bootloader CWM as well, before the flash I selected to preserve root and recovery but it didn't work... So now I have a phone that says T-Mobile constantly. /:

Hey llxaot, I'd be interested to know if you tried Kuma82's suggestion & if it worked. I'm in a similar boat ... working phone, but locked bootloader and not rooted on P769 with v20f OTA.
Kuma82, my phone is fully functional now. I'm "simply" trying to unlock bootloader & root the device. The methods in the links look to restore function of a device that's been soft-bricked, etc.
Is this the only currently known method for unlocking bootloader on P769 v20f?
Basically get fastboot working via Lelus script, flash the uboot and xloader from the 3rd link in that post & I'll be unlocked & have ICS recovery on device?
Then, I just need to flash back JB, flash CWM recovery (if I want) and root?
SO DAMN CONFUSING...this is by far the most difficult phone I've ever worked with.

I fixed it with Lelus' help. Kuma's would definitely work but I can't seem to get fastboot to work. Anyways, what I did was went into LG PC Suite and clicked on Device -> Emergency Recovery or something like that. Make sure you don't have the local server setup from cmahendra's offline KDZ flash method. Then you just find where you put in your device's IMEI code or whatever and click OK, it'll flash the stock v20F firmware straight from LG's server to your phone! Then you have to re-root (I recommend LG Pwn method) and install busybox and then flash Artas locked CWM recovery. About the whole bootloader thing, just wait. @carloswii5 is making a video to upload soon on how to do it, that's when noobs like you and I can do this.
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..?

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?

This is only helpful is they have the H850 or H830 model number. If they do not, then unfortunately there is no root available but we are doing EVERYTHING we can to get this to work.

It sure is, but you will need to reflash the stock rom and bootloader for your phone. Firstly you will need to find the correct kdz for you device, or use Lg bridge/ LG UP to get back to stock.
Once you have done that you can relock your device in fastboot mode using "fastboot oem lock" heres a link on how to relock just in case your not sure
http://www.mylgphones.com/re-lock-your-bootloader-on-the-eropean-lg-g5-h850-variants.html
Let me know if i can help anymore, ill try my best
Please excuse any spelling mistakes send for my LG G5
Just for info: fastboot oem lock worked also for me with latest nougat.. Thats what i did actually... No need to go back
Can confirm, "fastboot oem lock" works.
Sorry for reviving the topic (I hate it) But this model needs some updates. Hope I can help someone. This model is defective....
I was looking on the internet and everyone says to downgrade to v10c to lock oem back on G5 H850.
Well, I tried to do it with LG UP, got an error, and got stuck on Download Mode (Firmare Update screen).
I opened the LG Bridge, went to Software Update screen and them clicked on Recover Faulty Updates.
Then it worked and flashed the V20a-EUR-XX, Android 7.0 Nougat.
Went to fastboot mode, typed fastboot oem lock, and everything went to initial state... :good:
So I confirm that works on the last update (until now) V20a.
Can I relock with v20d ???
I relocked with V20a so you would assume so
