Its just like HTC, They do support unlocking the bootloader. As stated on their website

HTC is committed to listening to users and delivering customer satisfaction. We have heard your voice and starting now, we will allow our bootloader to be unlocked for 2011 models going forward. Please keep an eye on this website for more details on which devices will be adding this feature. We are extremely pleased to see the energy and enthusiasm from our fans and loyal customers, and we are excited to see what you are capable of. HTC eagerly anticipates your innovations.

On the other hand, due to some of the carrier policies on unlocking the bootloader, HTC's hands are tied on their carrier branded phones, in which the carrier doesn't support bootloader unlocking. As HTC states here -

HTC is committed to assisting customers in unlocking bootloaders for HTC devices. However, due to some of our carrier customers concerns, certain models with specific restrictions may not be able to be unlocked. Please refer to our list of supported devices to see if your device is eligible for unlocking the bootloader.

So as you can see its not HTC its the carrier.... T-Mobile or any of the others that don't support unlocking.

It's to bad and BS too because I buy my phones and should be able to do what I want with it. That's one of the reasons why I ended up buying a Nexus 5 Google play edition... Funny that it's co-created with LG. I unlocked the bootloader, rooted and installed CWM in 2 min.

I almost didn't buy it because LG had their hand in it and after the LG L9 and the LG Motion that I have I was disapointed with them.....but this phone is Awesome!!

And then there are the Canadian users with Wind who ended up with this phone. Like me.

Bootloader situation is exactly the same as T-Mobile though. I suspect it actually is the T-Mobile variant, just with Wind's (much more basic) KDZ.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
isn't Wind basically the Canadian T-Mobile?

Help unlock the P769 here: http://www.change.org/petitions/lg-electronics-unlock-bootloader-of-optimus-l9-p769
[LG Optimus L9 P760, P765, P768, P769] Alucai Vivorvel:
That depends, is T-Mobile not from the US and has to put up with a monopoly on the wireless market? They're the fastest growing carrier in Canada, and they're also the only carrier to offer truly "Unlimited" plans (regarding data at least).

Unfortunately there's no LTE or WiFi calling like with T-Mobile. In fact AFAIK that's not even a thing here.

Mmmm, see, I'm not wrong. The bootloader situation is exactly the same as others down south are having. That is, some are able to unlock, while many still can't and likely never will.

I would immensely appreciate it though if you sent me via PM the exact steps you took to unlock. I've tried following every guide out there, and all I ended up with was the mirrored European ROM stuck on my phone that constantly rebooted normally when I tried the adb reboot oem-unlock command. Yes I followed every step, I tried it for a few days before I gave up. And I don't have a backup phone so you'll understand why I'm a bit reluctant to try again.
[LG Optimus L9 P760, P765, P768, P769] ISITBRICKED:
I dunno I followed the guides. I bet I could unlock any of these 'unlockable' phones if someone sent one to me.

If either of my two previous phones worked with AWS (a technology my carrier uses) I would just use them and work on my phone for a week at a time trying to get it unlocked. I probably followed the same guides you did. But, I'm almost certain that my phone was made after the time they started encrypting the bootloader. Some time in the latter part of June 2013, I think?

Zip files?

Getting all necessary files together to download and run, cant seem to dl zip pkg containing "Adb" "Recovery image" "V6.bin" and "V20_00.bin". Scrolling through posts noticed some other people were having same problem as me, but that was almost a year ago. Now, I have no problem researching on my own, BUT, going through 236 pages of posts.........not that much time on my hands. If someone could throw me a bone and point to a valid link, I would greatly appreciate it!!!!
[LG Optimus L9 P760, P765, P768, P769] xdrc45:
In the OP click on the "All Files in One Zip" when you get to the Mega site it asks if you have the Mega App just click on cancel, then hit your menu button and select "Request desktop site" and then you'll be able to download the zip.
[LG Optimus L9 P760, P765, P768, P769] captdago:
Thanks for that. Clarified a few things for me. When I get to Step 5-

5) Ok now that the 30 minutes or more have passed you need to go to the downloaded files and move

the "Android" folder to your "C:\" drive "dont worry just has adb files" now open a command prompt and

type the following

"cd c:\Android"

"adb devices" to make sure your phone is connected a list of numbers should appear

"adb reboot oem-unlock" and your phone should then reboot

then the lg logo will appear then a mirrored confirmation to unlock bootloader just press

the "Volume Up" button and it will confirm it then hold the power button until it reboots

everything works fine till my phone actually reboots. It doesnt give me any confirmation to unlock the bootloader, it just restarts itself. And takes me back to bizarro android where things are backwards, upside down, and life has just a little touch of blue to everything lol.

Any thoughts?
[LG Optimus L9 P760, P765, P768, P769] travioso:
That's basically the make it or break it point.. You can try the waiting period again and give it another go, or start recovering back.. some people it's taken a few tries before they get it.. some it's taken being on Wi-Fi then data, others, like me, just get the reboot with no unlock option..
[LG Optimus L9 P760, P765, P768, P769] captdago:
Thanks, appreciate it. Whats the best strategy of getting it back to what it was before all this crap? Not a newb by any means, but this phone has given me more problems than any phone Ive rooted and flashed in the past (including the HTC EVO V)

Make hard reset

Root with cyndia inspector

Install recovery

Flash fix touch screen zip file

Look for v20f u-boot to fix lg logo mirrored

(If you need help for the links, tell and I'll post 'em here for ya)

After that, you'll be able to update your phone to the latest stock kdz with not issues
[LG Optimus L9 P760, P765, P768, P769] captdago:
Do you mean Cydia Impactor? Havent used that one before. Only way i could root ms769 was with Kingo Root (does it matter which rooter?).

Links would be greatly appreciated! Maybe along with some step by step? Not my first rodeo, but i dont want to miss anything and end up right where I started. Thanks again!
[LG Optimus L9 P760, P765, P768, P769] captdago:
v20f?????

Cant find a useable link anywhere now that "h" is out. Seems like every mirror link I click on has the file removed. Does it have to be "f"? Can i flash a metro kdz or even a European one?

Edit: nevermind, found a v20f kdz.
[LG Optimus L9 P760, P765, P768, P769] wolfist:
Cyndia Impactor* you are right xD

Well, It worked fine that way in my lg p769bk T-mobile, make sure you have already installed lg-p760 drivers, and look for your kdz file by your country. Do not worry about Touch screen Fix and V20f u-boot fix, I guess they will work fine in your phone.

If you need me to tell you how to fix it step by step, tell me by here. for links use google, I´m little lazy to look for them now xD

Thanks I ended up downloading it via somebody else's thread...somewhere...after scouring the internet for days. Folder ended up being called L769. However, I don't know if anyone else is experiencing this problem, but I've tried countless tutorials and various methods[including the v11.bin injection method during offline kdz flash] yet still on the V20B cannot get my LG MS769 to unlock bootloader via oem-unlock. I had high hopes of installing a custom rom however, it appears impossible on this device. I do like it, however I'm pissed with LG for locking their bootloader. Or is it MetroPCS that did it? Either way, I'm going to proceed to simply flash T-Mobile's V20D so I can manually update if I want to.

If there is any way to get the bootloader unlocked via a simpler method, please do share.

I do have a question, do you have to get cell bar service for this to work? I connected to wifi plenty, unfortunately this phone I'm testing on was replaced by the one I'm currently using and the SIM is not working. Or the flashing screwed it up I'm not sure.

I am VERY familiar with flashing stuff via Offline KDZ and via fastboot and am willing to experiment with NVFlash and other methods.

I once saw a thread where the ending comments were that V20F was unlockable however thread was closed. Also, any idea what's up with the u-boot and x-loader I uploaded here? It's supposed to be hacked[for what IDK].
[LG Optimus L9 P760, P765, P768, P769] aistiss4:
Damn.. i can't unlock it too.. ;( i've tried every tutorial, but nothing.. it's impossible ;( also tried oem unlock on v20f.kdz but it was unsuccsesful too.. any new ideas?

Also, for cell bar service working, you have to install bootstrap recovery and flash radio.zip after you install v20b euro
[LG Optimus L9 P760, P765, P768, P769] UltraRoboto:
Although it may have already been thought up, cant we just make the euro20b a full stock ROM? It would negate the need of flashing kdz and make the NoObs post waaaayyy easier to understand.
[LG Optimus L9 P760, P765, P768, P769] Alucai Vivorvel:
Have fun figuring out how to keep the touchscreen from going bezerk and inverting the colours~! Normally I'd say that's a kernel issue (that's what happened to me on my Nexus 7 (2013) after flashing an incorrect kernel) but it's not like we can flash that separately. Thanks LG for putting everything into one "convenient" package known as a KDZ!
[LG Optimus L9 P760, P765, P768, P769] UltraRoboto:
I see... Hmm wish it was an easier process but lg doesn't like consumer imagination to make something better. That would lead to Lg thinking they are inferior to the consumer
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
They're just greedy. That's all. If you can't afford their flagship then too bad. No freedom for you....lol. It is a Korean company so I know how their simple minds work.
[LG Optimus L9 P760, P765, P768, P769] Alucai Vivorvel:
While I agree that they're greedy, isn't every major company? Except maybe Sony, they have a reputation for treating their customers right, because they (unlike many companies, including LG) recognize that, if your users aren't happy, they aren't going to give you any of their money.

Then again, you're right about the flagship thing. LG G2 and Nexus 4 & 5 users (both of which are made by LG) seem to be pretty happy. Honestly I'm used to it at this point, coming from the Samsung Galaxy Gio and Ace II X. But at least those didn't have a locked down Bootloader and eventually got some good custom ROMs!
[LG Optimus L9 P760, P765, P768, P769] travisnj:
Look up your freedom on the PS4... Sony is the same..

Sad corporations don't understand the basic premise.. It's my device, my choice, my money, my property.

We don't by a car and get told by the manufactures where we can go and do.. We don't buy gas and restricted where you can go or do when you please. You don't buy a refrigerator and told what food your allowed to put inside.. Etc...

Greed and control... Freedom of choice is always the winner, just wish they'd learn, we get burnt (yes) but they loose!
[LG Optimus L9 P760, P765, P768, P769] UltraRoboto:
Not exactly Sony, is giving updates for the Ps4 by user feedback(April will have a user-driven update) also I have a new idea, can you unpack a KDZ!! If so, we can deal with the inverted screen and just continue with unlocking the bl!
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
The thing is the bootloader is like the BIOS of a computer. It loads and checks if the image is signed by LG. Any changes made would have to get signed at the end....almost like a stamp of approval.

I read somewhere that there is a way to trick the bootloader by replacing the aboot with one that makes it skip the image verification. That would require a really talented dev with knowledge on how to dissect aboot using a disassembler.

I did manage to get [MENTION=5029238]shutt1e[/MENTION] to help a while back but it seems he needs for someone to donate a L9. Even then, he doesn't have much experience with TI boards so he may or may not be able to do it. Of course, we can give him a large donation to give him motivation but no one here seems willing to spend money. And so....here we are.

I wanted to flash cyanogen mod, and after flashing, i've got security alert. so i reflashed kdz with support tool and after that i succesful unlocked bootloader by adb unlock. so i'm wondering.. maybe we need first to get security error, when fix it and after that try to unlcok? anyone, who got unlocked, have you ever got security error?

Grrrrrrr!!!!!!!!!!!!!!!!!!!! Lol

so, after trying this method (and multiple others) all to no avail, I've reached the end of my rope. Phone (ms769 metroPCS) is stuck on inverted S/W update screen. Flashing offline KDZ (or online for that fact) has done nothing. It got stuck like this at 15% during one such method and wont even reach that point now. Tried downloading the proper drivers, alternate model drivers, nothing. Cant insert battery without update screen popping up, cant force a hard reset, nothing. Someone, anyone, please help!!!! Im not opposed to going to Metro and paying $15 to get a replacement phone (still under warranty) but i would prefer to either unlock the damn thing or at the very least get it back to where it was before!

[LG Optimus L9 P760, P765, P768, P769] Alucai Vivorvel:
Okay, if it's stuck at the update screen, you can try flashing your original KDZ, though you said it gets stuck at 15%, which usually happens after upgrading to Jelly Bean... But if you can't get it to boot normally... Hmm. Have you tried just holding the power button for a good solid minute while it's on the S/W Update screen?

Even if the reversed fastboot v.05 pops up, it doesn't mean that you installed the omap driver twice. It looks like you haven't installed the omap4430 driver twice. The fastboot is real tricky and if you don't do it properly (or move the usb cable to much during the process) it won't work. Did you follow the directions about making the device manger show all hidden devices.

Another possible reason for it failing at 15% might be your anti-virus. Disable it if you have it running.

Antivirus is disabled, phone doesnt move after i plug in usb and battery. i messed with the timing a little bit and got the first image (fastboot-sel1.jpg).

Type fastboot devices and i get "01638EE60B017013 fastboot" . i think i got it this time. if i leave it too long fastboot screen goes away and S/W Upgrade screen comes back........only this time its not backwards and the colors are back to normal. Still wont let me do a hard reset,
