When device is in adb sideload type in you command prompt adb devices. Do you see anything? Try Ctrl alt delete kill adb.exe in process the retry if adb sees the device I'd in adb side load mode then your good. If not you need to get the drivers to work by following step 8. If you do not see that option add a screen shot of your options.
[Nexus 5 General] jonyid:
I'm now getting the error message (i uninstalled and re-installed the drivers) "adb cannot run as root in production builds" at stage 3:

3) Open the command prompt from the directory above on your PC and type the command: 'adb reboot recovery'

http://www.theandroidsoul.com/nexus-5-driver-adb-fastboot-installation-guide/

this helped me

i used the naked driver and disabled the driver signature enforcement (only for windows 8 and 8.1)
[Nexus 5 General] Android The Greek:
Are you stock? Why are you using adb recovery? If adb works in the os but when you manually boot into recovery mode adb sideload and it says failed to install the drivers my method will work.
[Nexus 5 General] jonyid:
I'm 100% stock. This is the guide i was advised to use:

Section A: adb sideload

NOTE:Make sure you have the latest version of adb. It seems people are having issues with older versions. Its attached at the bottom

1) Download the OTA.zip on your PC, rename the file update.zip, then place file in the same directory as adb.

2) Make sure you have USB Debugging checking in the Developer Options, then connect your phone.

3) Open the command prompt from the directory above on your PC and type the command: 'adb reboot recovery'

4) When in recovery, you’ll see an android laying down. Press power then immediately press volume up and release. The menu will appear. Select “apply update from adb”

5) Using the command prompt type: 'adb sideload update.zip' The file will load and the update will begin.

6) When completed, select reboot.

I've installed the google drivers and when plugged in it recognises both the phone (no yellow ! there) and also an 'android device - android composite ADB interface" option. Both say that the drivers are up-to-date.
[Nexus 5 General] Android The Greek:
In recovery adb sideload do a adb devices in command prompt. What does it say
[Nexus 5 General] jonyid:
you mean at stage 3? it says:

List of devices attached

03b911s908eb03ff device
[Nexus 5 General] Android The Greek:
Why not manually put your device in adb sideload
[Nexus 5 General] jonyid:
How do i do this? Will it then allow me to install pretty quickly?
[Nexus 5 General] Android The Greek:
Pm me your number
[Nexus 5 General] jonyid:
i'm in the UK that's the problem
[Nexus 5 General] Sephiroth_Darko:

I did it on my home laptop it and it worked fine. But I understand how you could be a bit hesitate to do this on a work machine. Best of luck!

Thank You

You are the MAN.. Thank you so much.. I was so stressed out last night trying to figure this crap out.. I finally came across your post and saved me much headache

Thanks again, and have a great Weekend.
[Nexus 5 General] Android The Greek:
Thank you for being the first thanks after 800 views lol. I'm glad it helped you
[Nexus 5 General] rengokushogun:
Thanks

Another thanks here. Nexus 5 + Win 8.1. Windows was able to recognize device in developer mode, but not in recovery, this allowed me to receive OTA.

I was so frustrated with my Nexus 5 due to the email bug in Google's e-mail app. I would randomly / silently stop receiving e-mail / calendar updates. Sometimes rebooting fixes it sometimes it doesn't. I hope this is solved now. Camera fix is just icing on the cake for me.

Just wanted to say real quick that ill be having a 2nd shot at rooting and unlocking a co-workers l9 lets see what the real deal. My first attempt was good. Maybe it'll be one of two:

1. Like some one mentioned, maybe lg only gave a certain open time limited window and than relocked or what not.

2. Steps are being missed, rushed at highly anxious or hyped moments...lmao :)

Either way its worth another attempt.
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:

I've been trying like crazy to get my friends new L9s bootloader unlocked with no luck. Then my lg offline tool got uninstalled and I couldnt get it working correct again. Well in one last attempt I loaded the stuff on my neighbors laptop (xp) and gave it one last attempt except I did a few things different and it WORKED MY FIRST TRY! Now I think it may of been the steps I skipped/ changed that made it work. Now to what I did. First I flashed v10g except this time I used the 760 version. I ran the bin file in the ICS rootguide folder instead of JB. I then proceeded to flashing v20b as shown in the video how-to except I DID NOT swap the bin file for root instead I added the radio while flashing. After it was complete I ran the bin file from ICS in rootguide again. I let the phone sit for 45 mins on data followed by 45 mins on wifi. Checked adb devices and it did not reconize it so I ran the JB bin file. Checked devices again, it reconized it. Typed the command and it rebooted right to the unlock screen! I should also add my first failed attempts was on windows 8 x64. Hope this helps someone else get it done! I almost gave up on it, luckly I did that one last try!

The partition dump was supposed to be taken from device with unlock token. It means that your phone should be able to enter the BL unlock screen but you shouldn't choose unlock option prior to make a dump.

Were you able to enter the unlock screen before making a nv dump?

Shouldn't we ask those who wrote the guides for unlocking the bootloader to ask everybody who attempt to unlock the bootloader and manage to get to the unlock screen to dump the nv partition? Maybe this would help those who are trying to unlock the bootloader but who have not succeeded yet...
[LG Optimus L9 P760, P765, P768, P769] stunts513:
I wouldn't mind dumping my nv partition, but as I have seen it mentioned the unlocking process needs to have data and I don't have a data plan, can anyone confirm I need data because the way I see it either way its just data being routed through the internet, and I don't feel like having to fix my phone after getting the screen messed up unless I have to.

On a side note I was going to mention the device I'm posting from(a kindle fire HD) has similar hardware to the lg l9, excluding the slightly newer omap processor, it has the same GPU, however the kindle fire 1 has same exact processor and GPU as an l9, don't know if I'm really making a point but I believe someone was looking at devices with similar u-boot's or something so I thought I'd mention this device could also possibly be useful maybe. I'm not too great in the coding section so I could be completely off base but I just wanted to throw that out there.

I would assume if we can analyze the nvram we could make a program similar to idme to write the token to the nvram. Would make needing data not part of the process.

[LG Optimus L9 P760, P765, P768, P769] Eliminater74:
This whole thing is a pain. Why did LG leave room for unlocking 760 but not 769? Did something happen to make them do such a dirty trick? There has got to be a way. Someone with enough assembly language understanding that could go through the two roms and figure the difference between the two and try and mock it on the 769? Is that even possible or did they leave the bootloader part out of the 769 rom all together. Like I said there has got to be a way.

Just throwing in my two cents.. :)
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:

[LG Optimus L9 P760, P765, P768, P769] stunts513:
Yes they have' but it was only after flashing the p760's boot loader more or less from what I understand. And I agree forging a signature is probably really complex, but it really makes me wonder how people make key generators, and I know this is getting close to something I shouldn't talk about but i know there are key generators out there for certain programs that hand out a request code and require a code back from that, makes me wonder how they figures out a correlation that allowed them to create that and if it would work similarly to that in the case of signing files. Seems to me if there are multiple files with the same signature it would make it easier to determine how it's signed. Then again I am just rambling a bit...

Yea I signed the petition some time back, I'm all for supporting the unlocking of 769 rom. I feel it's my phone I should be able to do what I want with it. Just like my PC.

I put my p769 20h on Craig's list for $50 and no one will buy it! That's how desperate I am to get rid of this phone! It pisses me off that I payed $200 for this phone and own it straight out yet I still don't OWN IT! Its ridiculous! I have tried and tried every method of unlocking the boot loader this past week and i have got nothing but a head ache! I will never buy another lg phone again! I feel cheated because I feel in love with this phone when I used my sis in laws. Its fits me perfect. I may just end up donating this phone to one of the developers here once I buy a new phone. Any takers?
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
I agree 100% with you. And I feel the same way, I paid for it, for prepaid service at that, and I still cannot do with it what I want. But, I can go buy a new Windows PC right now and turn right around and install Ubuntu if I want. Why can't I do that with my phone. It's literally my blood and sweat that made the money to buy the damn thing to begin with...

And like you, I'm done with LG. I bought this device on the premise that it would be familiar, as I came to this phone from an Optimus T. Boy was I wrong. My low-end Optimus T has KitKat on it but I can't get KitKat on this POS that I call a daily driver...
