How to install drivers:(Credit goes to sguerrini97 - http://xdaforums.com/showthread.php?t=2119090)

Power off your phone and remove the battery.

Connect your phone (still without the battery) to the PC.

You will hear the sound of a new driver,

then the sound of a driver when it disconnects continuously.

Start -> Right click on "Computer" -> "Manage".

On the left column, click on "Device manager".

You will see a device that appear and disappear under "Other/Unknown Devices".

You must right click on the unknown device before it disappear, once clicked select "Driver Update".

*** Click on the second button (manually install driver) and insert the "usb_drv_windows" path (usb_drv_windows) and install the driver.

Disconnect the phone from the PC and power it off.

Run start.bat and choose option 1 (The first time that you do this, you have to install the drivers again. Repeat step ***)

NOTE:YOU WILL HAVE TO LOOK IN THE xu FOLDER FOR THE bin TO PUT IN THE "YOURS" FOLDER WHEN YOU DO THIS!!!!

**WHAT I DID AFTERWARDS**

Run Start.bat and enter Option 7(same process, battery out, connect to computer, find the any key and press it(pun intended), then put battery in after four seconds)

this SHOULD put your phone back to where the screen is not backwards. but the touchscreen part still is.

do to cmd

type "cd C:\RootLelusJB\stuff"(or wherever you extracted it to) and press enter

type adb devices and make sure your device shows up.

type adb reboot recovery

phone should reboot into recovery, however on my first try it showed up with the laying down android guy with a triangle above him. so i typed adb reboot and just pressed the volume down button when the LEDs flashed

phone will go into CWM recovery

press volume down to "backup and restore" press the power button

volume down to restore from external sdcard

find the backup you want to restore and press power go to yes restore

let it restore and then reboot

now the touchscreen is still inverted, so reboot the phone again to recovery

install .zip from sd card and install the cwm_ts_fix.zip(I'll include it in the download)

wait for it to install

reboot and viola. your phone is back to how you had it before trying to unlock the bootloader

I AM NOT RESPONSIBLE FOR IF THIS DOESNT WORK FOR YOUR PHONE.AND sguerrini97 ISN'T RESPONSIBLE EITHER. DO THIS AT YOUR OWN RISK!!!!
[LG Optimus L9 P760, P765, P768, P769] Hackjab:
Okay so when I get to the CMD part it keeps saying that my device is not found. What am I doing wrong here??

EDIT: Now it is saying ADB server is out of date

EDIT 2: Now it won't let me into recovery. Just reboots to the normal phone

EDIT 3: Still can't get into recovery but I fixed my touchscreen. Still wondering how I can get back to metro though? Need to get into that darn recovery :P BTW thanks for the help guys! Much appreciated.

EDIT 4: NVM I am in. Thanks for the help :) Guess I'll try to unlock bootloader some other time :/

Hi, is there any quick method of unrooting? I have to update to JB and I'd prefer to use the OTA method, but it won't let me because I'm rooted. I used the Cydia Impactor tool.
[LG Optimus L9 P760, P765, P768, P769] sleepingturtle:
You don't need to unroot to do an ota update. Use voodoo ota rootkeeper to restore root. If the ota fails, it is because you may have removed stock software. If so, do a restore using a kdz file. Use the lg software suite to do so. Back up your stuff first. If you want, do the upgrade via kdz. Same thing in the end. There are threads here that give instructions.

[LG Optimus L9 P760, P765, P768, P769] Alucai Vivorvel:
Err: 0x13E

That's the error message it shows after rebooting into the update screen.

The screen after rebooting normally.

I suspect this is due to Cydia Impactor installing CWM after rooting. The OTA likely only works with stock recovery.

I wouldn't be surprised if LG did indeed implement a check like that, considering just how locked down the P769 really is.

what android folder are they talking about during this step?

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

is it the file in dropbox or does it appear somewhere on your computer/phone because the drop box file doesn't work.
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
Forgive me for interjecting my 5 cents, but I have 2 observations: first, according to my sources, starting from summer 2013, all LGs 769 in the US have encrypted bootloaders, which means there is NO WAY these bootloaders can be unlocked; and second, I haven't seen a thread on XDA where no one can put together all necessary files (without dead links) to at least have the full arsenal of tools for someone to try. Or no one can put a single guide on how to unlock without linking 3, 4 or 5 other threads. Sheesh...

And one suggestion: I come from Xperia ION thread where there is a bunch of custom roms, including CM, AOKP and PAC are made available for phones with locked bootloaders. It is possible. All you need to do is to intercept stock kernel's call for pre_hardware file or chargemon and then call instead your custom rom. It has been done... and is working.

Do what is possible, because if your bootloader is encrypted, you won't succeed in unlocking it...
[LG Optimus L9 P760, P765, P768, P769] xdrc45:
That folder is basically just the adb files needed from the android-sdk (its not the whole android-sdk)

This allows your PC to communicate, run commands, push/pull files and more with the phone through adb commands.

I'm not sure if it's in that dropbox file or not, as I already have the whole SDK installed. If was there you would see a folder named "Android" and that whole folder goes on the root of the C:\ drive of the PC

[MENTION=5075064]optimumpro[/MENTION]

Thanks for the suggestions.

Any idea on how or where to start with intercepting the stock kernel's call?
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
Head to Sony Xperia ION development section, download either CM, PAC or AOKP rom for locked bootloaders. Check lib and wifi folder as well as step2 script. Everything is there. You will need to extract intramfs from boot.img of your device's custom rom, i.e., CM, PAC or AOKP and put those in CM.tar. Put your favorite recovery into Recovery.tar (all inside lib&wifi) and recompile (rezip). The way it works is that your stock kernel calls for pre_hardware file. You modify pre_hardware to call for step2 script and step2 calls for CM.tar, which is basically your custom kernel's initrams. So, your stock kernel thinks that all init.... files are its own, while in reality, they belong to CM based rom. Also check flashing script, as it has to be modified to install lib*wifi files into system. Also, your busybox binary in xbin must be replaced with static one (available in ION thread) for this to work.

For Xperia all custom roms based on JB 4.1.2 work fine. Later roms so far have problems, but that's because there is no available stock kernel for later JB versions (not released yet). But at least ION now has all custom roms based on JB 4.1.2 (that would be CM10 and others).

You can also check discussion in Xperia S/ION general section, where the above is described in more detail.

Can someone help me out with this? I bought the MetroPCS variant of this phone and I'm following the steps correctly up until when he goes to the KDZ and starts the upgrade, it keeps popping up LG Mobile Support Tool around half way when it's "checking for new LGMobile update program". Is there anyway to stop this from popping up?

EDIT: I don't know what the hell I did but it started to work!
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
Well seems worth a try. We'd need someone to modify the existing roms first. I didn't even know that it was possible to use say kitkat on jellybean kernel. What exactly are the bugs that arise when you do so? I know that we will have different problems that will be device specific but whatever.

[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
LOL. I know right? It's a hot mess. The news that the bootloader is encrypted doesn't surprise me. At least now there is a reason why the unlock command doesn't work on certain P769 models that shipped with JB 4.1.2.

As far as the kernel thing you're talking about....hasn't omgbossis21 tried everything already? Doesn't the image need to be signed by LG?
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
You can't touch kernel on locked boot loaders. You work with image of the custom rom (extract initramfs). This method intercepts stock kernel's call for operating files and redirects them to custom rom files. That's all and as long as stock and custom kernels are based on the same Android version, this should work. In other words, stock ICS kernel should work with CM9, stock 4.1.2 should work with CM10 etc.

That's the same as the 2nd init that I've mentioned several times. I've briefly looked in to it. No promises but I'll look thru what was previously posted and see if I can't come up with something.
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
You can't have kitkat rom working with jb kernel, the point is to make stock jb kernel work with jb custom rom. The sticking part would be to properly extract initramfs from custom jb kernel. As far as I know, it could only be done in Linux. And the custom rom version must match stock kernel, i.e, jb 4.1.2 stock and CM10. Also, on ION, some stock binaries had to be added to have WIFI working...
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
No, it is not the same as second init. There is no second init here. You have one set of initramfs put in sys where they are supposed to be. It is just that stock kernel calls for its own initramfs, but instead gets custom ones.

I can't find CM10 based rom for LG-P769. If I could get clean deodexed stock 4.1.2 rom and CM-10 based rom, I can try to make it work. It has to be CM10 and not higher, because the latest stock kernel is 4.1.2. (My wife has this phone and wouldn't mind to have a custom rom. :) )

No, you are not getting anywhere. You got a response from a trained monkey sitting 4000 miles from you who has no idea what a bootloader is. They teach them to be nice to customers and he did his job well. No one should complain. You bought a branded device, i.e, device with severely limited abilities at a hefty discount. You got what you paid for. Next time, buy an unbranded and fully unlockable device. It surely is going to cost you a lot more, but you will get all the options.
[LG Optimus L9 P760, P765, P768, P769] DJ Scooby Doo:
Mate, that sounds so uneducated. You can make a difference with just a little noise. See, I have moved on to an HTC Sensation XE (European model) phone, but I'm not giving up the fight. How do you think the world has changed if you made a bit of noise?
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
There is no reason to make it personal, but if you mentioned being uneducated, let me give you my 2 cents.. LG has a contract with T-Mobile for branded devices. And part of the contract is making bootloaders unlocked. The only way for LG to unlock is if T-Mobile would allow that. LG can't unlock on their own without a major breach that could cost them dearly. Now, sometimes, happy hacks can go around the technology and undo the lock, but technology gets better and bootloaders get encrypted. And there is nothing you can do to unlock.

The point is, if you want to try to petition, LG is the wrong party. Ask T-Mobile. And I already have an answer for you: you'll get T-Mobile's trained monkey who will send you to LG. :)
[LG Optimus L9 P760, P765, P768, P769] DJ Scooby Doo:
My bro, I didn't say you were uneducated, I said that specific thing you said sounded uneducated. HTC has a contract with T-Mobile too and you can unlock their bootloaders with HTC Dev, how does this work then? Explain to me. Making some noise could work, just wait on it bro. Just wait on it.
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
If a manufacturer changes practices for all their devices, they will change carrier contracts accordingly (the way HTC did), but I doubt LG would do it for one device. By the way, most if not all unbranded devices have unlockable bootloaders.
[LG Optimus L9 P760, P765, P768, P769] DJ Scooby Doo:
But the Sensation wasn't unbranded, nor was the Amaze. I'm also pretty sure that the Motorola phones that the dude made a petition for wasn't unbranded either.
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
You are missing the point: HTC has changed their policies on all devices. They didn't just unlock a single device...
[LG Optimus L9 P760, P765, P768, P769] DJ Scooby Doo:
And as I said before, LG unlocks their devices also. If they unlocked the other variants of the phone, what makes you think that they can't unlock this one?
[LG Optimus L9 P760, P765, P768, P769] optimumpro:
Most devices come out with locked bootloaders and most manufacturers have a process for unlocking. Things are different with branded devices, because here manufacturers are bound by contracts with carriers, especially US carriers who think they own consumers (and they indeed do). US market is different in that manufacturers have a little chance to grab market share unless they go to owners of consumers (carriers). Nokia found it the hard way.

Again, the point is LG won't be talking to T-Mobile to unlock P769. They will only do so if they decide to unlock everything. I don't know how to say it more clear: no petition to unlock a single device has a chance to succeed... . But good luck anyway.
