I'm having problems trying to sort this out, I've jut spend over an our trying to update the driver for my phone with the device manager but I can't tell what the phones name is under the device manager... long story short, If there is anyway to simplify the process for me due to my inability understand the Android Lingo :)

Gotta follow the steps on the post. Ok go to the post I sent you which will immediately send you to another post to install omap4 on your phone. Then go back to the original post to install the u-boot and x-loader for p769 then get back into the fastboot and choose 1 for fastboot. Enter sw upgrade mode and flash your ROM.

No matter what I do the program always says Waiting for OMAP44xx Device... and I think I'm having problems installing this driver. I am using Windows 8 so do you think this might have anything to do with it?
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
I have tried on xp and win 7 which worked so idk about 8. Here try to follow just this for omap4boot.

So it turns out it was because I was using Windows 8 ( or possibly my surface pro) , I haven't flashed my phone yet but at least I've installed the driver and I'm running Fast Boot now, Thanks Nathan.7118391

I have reached a point where my phone has the the LG logo in black and white backwards, and it says fastboot v0.2 backwards... but the post doesn't say anything about how to flash the rom aferwards. and does it need to be an official kdz or can it be aokp?

His has an easy option to flash (with fastboot), the ice cream x & u for your device.

You need to do this to get the offline flash working.

Once you flash the x & u run the offline flash. Look at carloswii5 video to see how it is done.

[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
Ok I'm assuming you are having trouble with the omap4boot commands. As the instructions say take out your battery from your phone and disconnect from computer. Run the program from your computer to get to the menu then select #3 for Prada and once you press enter put the usb cord into the phone then wait about 5 seconds then place your battery in. Should be smooth sailing after that. Once it asks you do you want fastboot just say no, and no to loading u-boot. Just disconnect your phone and you are done with this part. .Let me know when you are finished with this.

You can't flash a custom ROM in fastboot so you will have to load a stock kdz file but that's later. .
[LG Optimus L9 P760, P765, P768, P769] CoryKenzie:
I finished that, I got all the way to the end where it says

--------------------------------------------

------------------------------

Please remove USB cable

and wait until LG Logo on

then reconnent USB cable again

------------------------------

fastboot devices (y/N) ? and press <ENTER> n

ls: resigned/p940-MLO*.bin: No such file or directory

Do you want to replace u-boot (y/N) ?n

ls: cwm/p940-*.img: No such file or directory

Press any key to continue . . .

I assume that is all I have to do here so should I just follow the New Lelus method now?
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
No Lelus method yet. You can do as Kuma has said above or what I did. Either way we are both trying to help you. Now that you got that done and congrats on that! Follow this http://xdaforums.com/showpost.php?p=44325657&postcount=4&nocache=1&z=6862240654882044 which will help you with getting u-boot and x-loader on your phone. Skip getting the drivers because you already did that. But you will do the same thing that you did with the earlier program just now you are installing the x-loader and u-boot for your phone so your computer can "see" it. Once you've done that then you can flash with the Lelus method. But be sure to get it done right and practice if you need to.
[LG Optimus L9 P760, P765, P768, P769] CoryKenzie:
OK thanks for clearing my confusion on the Lelus method... but I have tried both Omap... and Fastboot, my problem with fastboot is that it get to step 3 of http://xdaforums.com/showpost.php?p=44325657&postcount=4&nocache=1&z=6862240654882044

My phone screen is inverted and it says fastboot, but my computer never says press any button, just stops at <waiting for device>

about 1 minute after this appears, my phone just reboots into the loop. and I've seen other people post the entire script so I know my phone, or computer is stopping right before the x-loader and u-booter, for whatever reason.
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
Ah, ok, ok, ok. . .Try this: bring the program up with the choices then press #5 but don't hit enter just yet. Now take your battery out and put the usb into the computer but don't connect it to your phone. Hold the cable next the plug in and hit enter. . .then it will say something like requesting omap4boot that's when you place the cable into your phone then it will go through some stuff pretty fast don't pay any attention just count in your head to 4 or 5 seconds then put your battery and wait 'till the fastboot comes up. . .that's it. once that happens your phone is u-boot and x-load ready.

After that this point sucked for me. You have to take out the battery and unplug your phone from your computer at the same time then wait 2 seconds and put your battery back in then immediately afterward hold the volume up button while inserting your cable back into the computer. . .wait for S/W upgrade mode. THEN YOU DO THE LELUS METHOD!!!
[LG Optimus L9 P760, P765, P768, P769] Lelus:

[LG Optimus L9 P760, P765, P768, P769] CoryKenzie:
I am running as admin... and as a response to Nathan.7118391 BWUUAAA :eek : ,

I unplugged everything from my phone, then I press 5.

I press enter on the next page that says something about plugging out the phone and taking out the battery

Then I click Enter and plug in my phone. It goes through some things and than says " Wait 5 -lelelele

Than I put in the battery and it runs down to

** Done**

<Waiting for Device>

Does it matter that my phone is on Jellybean, or that I have an unlocked Bootloader?
[LG Optimus L9 P760, P765, P768, P769] Lelus:
Nope, it doesn't matter ...have you tried using different usb port ? preferably not usb3
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
LOL great! Like Lelus said it doesn't matter but I think you are done. Now do it all over again on that page except when you load the program again you should have an option #1 for fastboot. Just press #1 and do the same thing you did before and you should be good.

Now after that it gets a bit tricky which it was I was telling you about taking out the battery for 2 seconds and unplugging from computer then putting the battery back in with the vol up button pressed while plugging back into the computer for S/W Upgrade mode. Once you get that done then you are ready for Lelus root. And don't worry about trying to add the bin file to root just let the program do it's thing and then we can get you a very simple root method. have you gotten your kdz file yet? Check Kuma post a few above this one and download your ROM.
[LG Optimus L9 P760, P765, P768, P769] CoryKenzie:
So If I understand correctly you are saying that after I have pressed 5 and gone all the way down to <waiting for phone>

I should re-open the program and press 1 which takes me to fastboot which ends in

C:\fastboot\fastboot\yours>

than I should quickly and simultaneously remove the cord and battery... wait 2 seconds... plug them both back in...while holding the volume up button

which will than put my phone in S/W mode?

Why not just put my phone in S/W mode from the getgo?

P.S. If I seem kinda rusty at this it's because I am only 16 and have never done anything like this EVA before lol
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
Yup sounds like you got it! And I do believe that your phone has to be in fastboot in order for the computer to be able to see your phone when you put it in sw upgrade mode.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
Sorry I didn't break it down enough for you. You have to get fastboot up and running. Jellybean does not operate when starting in S/W mode, that's why you get the connection problem.

[LG Optimus L9 P760, P765, P768, P769] Lelus:
I don't think it's the drivers since usbboot.exe is able to send 2ndboot and fastboot.bin to the phone(he sees inverted logo and fastboot etc)

I'd say fastboot.exe isn't getting admin privileges and that is the problem.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Yeah you are right, but it just sounds like a driver issues/or bad connection, from what he is describing though. I think the wire might be faulty, I know mine is. I try not to move it much while fastbooting this way or I will get problems.

If I don't start your batch script as admin, I don't get any options to run anything.

Yeah having a clean operating system is the key to success with this type of stuff.

Questions for [MENTION=5232919]CoryKenzie[/MENTION]

1. Did you see the inverted lg logo (fastboot 2.0) for Lelus fastboot script & and the other fastboot, or you saw the inverted lg on only one of them?

It you do plan on checking fastboot out later. (I say later because your device should be working now with that lg recovery software provide by Lelus) Try not to move your device much. When I enter this fastboot, I leave my phone face (screen) down when I enter the wire and battery.

Ok you know what. . .just keep going. once you do the fastboot thing then try to put your phone in S/W Upgrade mode. . .when you do that then go to the link for the Cmahendra directions for Lelus Root Method. Start getting your computer ready for the flash. Just keep going until you hit a wall. The only way that I knew I did something wrong was wen I tried to flash the ROM which it stopped at 15% saying that my phone was not connected even though I did connect it. Turns out the second time that I got the security error I decided that I knew everything and did it by memory. Well my memory forgot that I hadn't installed the u-boot and the x-loader for ics which is where the 15% error came from. Do the fastboot #5 for u- and x-loader then do it again to place in fastboot. Just like you did in the video then try to enter S/W upgrade mode. Once you do that then just follow the root method stuff to flash your ROM. Oh yeah and download your ROM!

Cory, if that recovery software that lelus linked you, doesn't work. We will try fastboot on the other windows 7 you have. If that lg p2 driver doesn't come up, I'm afraid it might just be your phone that is causing the problem. Maybe you thought it was the font app that bricked your phone, but actually it was just your phone that is the problem.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
No that will not work on our device. The x-loader and the u-boot are img. Having TI Board is the first step, that means you installed the omap4430 driver once. So does your phone charge? Either your phone is really broke or your battery doesn't have a charge to make it to the next step (install omap4430 the second time). That's all the advice a have.
[LG Optimus L9 P760, P765, P768, P769] CoryKenzie:
My phone battery maintains charge and and if by load omap4430 driver the second time you mean that after it asks me to wait 5 seconds it doesn't past that part... than that is untrue because it runs every part exept u-boot and x-loader.

Is there a comand that I could just type in to automatically load the u-boot and x-loader?
