Are there any new developments on the P769 bootloader unlock problem? I have tried all the steps, flash V20B, wait 30 mins and adb oem unlock, nothing works. FU LG.
Did u flash the radio.zip from the sdcard files? Did u leave screen on while waiting the entire time?

Yes, I flashed the radio.zip and connected to wifi, but do we need to keep the screen on the entire time?
That's what worked for me first attempt. strong WiFi strong radio
Signal screen on..1 hour..unlock..left phone plugged into PC screen on entire time

Notes It seems if you restore your phone tool using LG update tool .. it relocks the bootloader (assuming) in my case i had done it since 10.1 had BT issues ..went back to stock ..and unlocked it again today This is what you do :
what ever rom your on doesnt matter .
1.first Root the phone many way to root the phone .. then install busybox from market and install CWM (using the L9installer apk..Then enable wifi and debugging mode .also enable touches do these before proceding the KDZ!
Then install
2.then using the V20F_00.kdz your root the phone again like in step 1 install busybox from market and install CWM.then apply the touch screen fix .
You should have a working phone now with radio signal.Then wait about 40 mins then do oem-unlock command .. Note it will not boot into LG logo phone will just reboot .. Then to confirm if the bootloader is unlocked go to S/W mode on top it should say bootloader status is unlocked .just did this and flashed CM10.2
Maybe ill clean up this post soon if its too confusing ..
So what you mean is that it doesn't go into the fastboot screen to unlock the bootloader?

HAHA Yes! But I am going to keep trying. MAYBE I will get lucky? :fingers-crossed:
You know, I just found out that the hard reset might be causing a semi-lock of the bootloader. I'm going to try flashing the kdz twice....ugh.

It means that the euro kdz becomes partially locked at this point. According to what my friend told me, when the unlock command gets sent, LG checks the status of the bootloader. If they notice a semi-lock, they lock it down.
If that's the case, they are so evil.

Hello,
So whats going on is my QI wireless on my phone stopped charging. so i called verizon to get a replacement which they are overnighting tonight to me. so my question is, is there a way (step by step) to just put the Orignal Recovery Flash rom back on the phone and just lock the bootloader without resetting the phone? if so and do that. well the tamper disappear on the phone as well? ?? because they want the phone how it is. they dont want me to do a phone reset so they can see what cause the problem...
So 2nd question if i don't fix the rooting and ship the phone as is to verizon. Do you think i well get charged for rooting my phone???
Thanks!
Flash a stock rom and kernel, restore all your apps and stuff, delete any root apps, remove supreuser/SuperSU, flash the stock recovery, and relock if you feel like it. If you all that you should be good.
Or just ruu and relock your phone. As long as the problem still persists they won't care that you wiped it.
Sent from my HTC6435LVW using xda app-developers app
I hope the new one doesn't come updated because if so you won't be able to root. I would restore the old one and see if the wireless charging works again if so you might want to keep it if the new one is updated.

The download on that post is a zip file, which you would flash in recovery to have a stock Rom. Then you would restore your apps, remove any root apps, remove superuser, put a stock recovery on there and relock.

Oh and Sorry for the cruddy tutorial will update it tomorrow its 3:24 am in Cali and i want to go to Sleep
Part 1
(Update) Well Its Official we have an unlocked bootloader on the P769 i attached a picture sorry its kinda blury i had to take it with my sisters ipod...
Ok well what you have to do dont worry its really easy
1) Download V20F kdz
2) Flash That kdz (dont worry about root well get that later....)
3) After it Boots Make sure you have signal to network (doesnt matter if it has service or not i havent paid mine yet and it unlocked)
4) Connect Phone To Computer and make sure you have USB Debugging on and then run the Following Command
"adb reboot oem-unlock"
after you run that command your phone should reboot i do not know why but there is no prompt like the p760 (if you want to confirm you have it unlocked do the following 1)turn off phone then hold volume up and connect usb from computer and you should get S/W update and at the top left Bootloader Status: Unlocked)
and there you have official unlocked
Part 2
ok now for those of you who did it the hard way and unlocked before i recommend you take this unlock but up to you first what you wan to do is
Make sure you have this installed "http://forum.xda-developers.com/showthread.php?t=2119090" and setup
then download this
Lelus Fastboot Script : "http://forum.xda-developers.com/showthread.php?t=2292828'
and then choose the one that says P769 ICS U and X Boot choose that then it will tell you do the battery thing then it will flash and now you have original X and U Boot Now you can flash the kdz and do the unlock make sure you do this first!!!
Part 3
Now to flash a recovery and flash root
Make sure you have it on your sd card there is different ones link are scattered so ill get them in a while
Install this http://forum.xda-developers.com/showthread.php?t=2292828 then start fastboot and flash a recovery image to your phone
then make sure you have the superuser zip on your sdcard then boot to recovery and flash the zip after you flash it now reboot and enjoy you have unlocked bootloader with root and cwm now just flash another rom and there Cheers

I am a huge noob
Hey i have no idea what to do i am a huge noon at these things andi want to get my lg optimus l9 p769 rooted. What relly confused me is when you said i had to flash something and i thought you had to be rooted to do that. Please help.
I tried the ADB command and the device rebooted. When I went into software update mode it did not mention anything about the bootloader being unlocked. I'm going to try again in 30 minutes as I had just put in the SIM card prior to attempting to unlock. Not sure if it makes a difference but the SIM card does not have active service and I flashed the 20D KDZ before doing the OTA update to 20F.
EDIT: Waited 2 hours and tried to unlock again, no dice. I guess I'll wait for further instructions.
Nice find! I'll have to try this tonight.

I know this is a noob question, but where's the KDZ at? It isn't in cmahendra's repository and I really want to unlock my bootloader tonight. BTW, I'm not new. Well technically yes, but I've been lurking these forums since late January. So um, yeah. I need the KDZ and such. I'm already on P769F but I got it through OTA... I went into Terminal Emulator and I thought I had something, I went "su" and then "reboot oem-unlock" and it would unlock, but my phone didn't show the confirmation in S/W update mode. I'm using artas locked bootloader recovery if that means anything. Wait, actually I'm going to try something.. I might have just answered my plethora of questions. Sorry for the useless post xD
Thanks Carloswii5. When you get a chance, please give some more detail, and possibly links to the correct version of what we need to download\install. Great find, though!

I got the tmobile lg p769 on wind mobile v21b. I just did the reboot oem-unlock through terminal. Then powered off phone and plugged in sw upgrade. And says bootloader status unlocked. It was backwards because mines been unlocked for a while. But maybe u could use the v21b cwm backup and do the unlock. I stayed on the wind rom for move apps to sd is built in. I get the same 4g coverage from tmobile. Just changed the apns.config.xml with tmobiles v20f and set up apns manully. The same tweaks work on the wind version as the others. Oh theres a telepony.xml u need to replace as well. Just thought everyone should know how much of an asset wind 21b can be no matter what carrier u got.
Type su in terminal then press enter. Then type unlock command. It rebooted but I'm not near a PC to confirm (20f via cwm update).

ok,so i just got the P769 and unlocked the bootloader and rooted and all that. so i tried going back to stock through KDZ and lost root. so i tried to regain root using a guide on this forum saying to use fastboot and i did that and got to the inverse lg logo and now my screen is messed up. not like the "Wonky" type way when you first unlock the BL but on the bottom of the screen seems to be borked now.. any ideas? ive tried flashing the TS cwm fix again and the f20 u boot and nothing...
FIXED!
Why would you want to go back to stock? LOL.
I would use fastboot and use these commands....
fastboot erase system
fastboot erase userdata
fastboot erase cache
fastboot erase recovery
fastboot erase boot
Then flash u and x and try to offline flash the kdz.

Hey there, I'm new to the LG Optimus L9 (P769) community and I don't know if this is normal but I don't remember seeing this when I first turned on my phone. The back and menu buttons blink during boot. Is that normal? The only thing I've done is root and install a custom recovery. It blinks at the LG logo.
That's normal after you install the 2nd init recovery. If you push the vol down button while they're flashing, it takes you to CWM.

Lol I saw people posting around about it. I was thinking of installing that themed ROM for our device. LG sucks lol. Not only you can't unlock the boot loader you can't access it. I'm so use to being able to fastboot boot.img and recovery. I'm kind of confused about something though. When the phone receives an ota , how does it flash it by itself? I know with HTC devices, it reboots to stock recovery and install and I know you can install ruu in hboot.
