Hi there.

First of all I want to stat that I'm a complete noob at android customization. My LG optimus L9 P760 started lagging enormously and a factory reset manages to make things better for a certain amount of time and it gets ever worse. So I was thinking to tweak things a little and maybe even instal a custom ROM but obvious I found out that wasn't easy and I'm having trouble even rooting my device.

I found your post to be easy and straight forward, with all steps nicely explained with screenshots, but even then I'm having difficulties with the unlocking of the bootloader.

I have followed all the steps for thew unlocking and everything looks fine, but sill when I insert the lines in command prompt and the phone reboots I never get the flashboot mode, I just get a fresh start on my phone. Ther never was a possibility of doing the final steps of your tutorial.

What am I doing wrong??

Use the guide below to re-flash your phone. Hold the volume up button while plugging the phone in to USB to your computer to get to S/W upgrade mode and follow the instructions in the link below with a stock KDZ file. Worked for me.

LG P768(Lucked Bootloader) easily rooted using your LGPwn. It seems to be rooted since Titanium backup was granted and seems to work OK.
Can I also flash recovery on Looked Bootloader?

No! Flashing recovery on the locked boot loader has bricked a number of these, including mine

I'm still wondering how did root work on a locked bootloader? I simply followed steps and the devices seems to be rooted all right.

==================================================

STEP BY STEP NEW GUIDE to Easy Root Without PC + Unlock of LG L9 [No Fastboot]
DIRECTLY ON PHONE

Introduction
  • This visual step by step two in one guide can ROOT (unlocked) LG L9 and FLASH RECOVERY without PC.
  • Useful for new LG L9 phone owners or someone who just unbricked phone by flashing stock kdz. Works on any stock rom.
  • ROOTING WAS NEVER A FUN LIKE THIS BEFORE. BYE BYE YOU BLOODY @#[email protected]# FASTBOOT METHOD. SO NO DIFFICULT FASTBOOT DRIVER INSTALLATION. THIS AMAZING ROOTING METHOD DOES NOT NEED FASTBOOT METHOD AT ALL
  • 100% WORKING , TESTED ON MY PHONE AND THEN MADE GUIDE.
  • This is not my own discovery. But for newbies like me, I always have gathered all INFORMATION and FILES together and made this useful step by step guide. Experts can still stay away, than criticize.
Step 1) Preparations:-
  • In Settings >>> Developer Options >>> Select check mark on for "USB Debugging Mode"
  • In Settings >>> Security >>> Select check mark on for "Unknown Resources"
  • Download this MAIN ROOTING zip file and extract/copy all files in the root folder of sdcard on phone. The list of files can be seen in this image.


Step 2) Install LGPwn.apk

From file-manager, find and Install and Run "LGPwn.apk" which you will show first screen to select as "Root Me" as shown in following screen. Then you will see first time SuperSU asking for granting permission, select "Deny" yes "Deny" for first time. (In some cases this SuperUser permission box may not come, dont worry about that.)



Step 3)

Now you will see four instruction screens as follows, just bypass them by clicking "Next" like we always do. Its nothing special but information about its rooting process.




Step 4)

Now you will see EULA License, you need to read and "Accept", now LGPwn will backup root information and will show next screen titled "Backup" but press "Restore" button in that screen as shown below.





Step 5)

Now you will see "Restore Location" screen, select "Internal Storage"
Then "Restore" screen where you click on "LGPwn" entry as shown below.




Step 6)

Then "Selection" Screen will come with dialogue box Cross Model, click "OK" and "Continue" as shown below.
Then another Warning dialogue box appears, click "Restore" and then press "Continue" on main page to go ahead.




Step 7)

Now phone is almost rooted but still some more step to finish it fully.




Step 8) Install Super User.

Now from file manager find , install and run "Super SU" app we copied before. ("eu.chainfire.supersu-1.apk")

Now your phone is rooted fully. Close SuperSU app.




Step 9) Install Recovery with Flashify

Now from file manager find , install and run "Flashify" app we copied before. ("com.cgollner.flashify-1.apk")

"Accept" the Disclaimer, "Grant" Superuser permission, and then click on "Choose a file" on Flash Recovery section box.




Step 10)

Now Flashify will ask you for file-manager name to select Recovery file. Select "Flashify File Explorer" and press "Once".
Now File Explorer will show root area of Phone, here select "SDCARD" and then select file named "recovery-clockwork-touch-6.0.4.5-p760.img" and confirm it by pressing "Yup!"
Note: You can choose any other compatible recovery like PhilzRecovery or TWRP.

When Flashify successfully copies recovery in Recovery partition you should press "REBOOT NOW" to go in recovery mode.



Step 11)

When phone reboots you will see CWM 6.0.4.5 Recovery main screen. YOU ARE DONE!!! Enjoy




This is all CLICK AND GO kind of thing and everything went very smooth on my LG L9 P765 in single attempt like a charm and took less than 2 minutes.

Hope it helps! As usual!

At step 11 upon reboot it goes to the android guy with a red box popping out of his chest, would that mean the boot loader is still locked? Also i would prefer twrp over cwm can this also be achieved. I have a few TWRP versions for the 769 flashable.

Please know and understand some xda basics. Quoting whole opening post is wrong.

Thumbs up Clean the tutorials and update root method with this
1. Download and install the drivers for Windows : http://tool.xcdn.gdms.lge.com/dn/dow...=UW00120120425

2. Download and install the app http://www.kingoapp.com/android-root.htm

3. In developer section select "Debugging Mode" as ON, and "Install from Unknown Sources" as ON in Phone Settings.

4. Run Kingo ROOT.

5. Connect your phone to computer in charging mode. Press ROOT button.

6. The device should restart itself with SuperSu installed.

7. You will be asked to give access to ADB shell, do it.

8. That is all! Your phone is rooted.

This method works perfectly were others like LGpwn Failed miserably...

Exclamation LG Security error
Hello,
Guide was very easy thank you, Rooted and everything stays fine unless I try to flash the CWM. After reboot I'm getting 'security error' with the LG logo and I have to reinstall the KDZ. and this is the 4th time having the same issue. P765 with V20C.

I was using artur 182x's Kitkat build then had a brick. After flashing the KDZ this started.

Any help ?

Edit : I tried the play store version of Flashify.. And didn't even tried to flash the included CWMs cause I guessed its for p760s. I was trying with Artur's custom TWRP (flashed many times before) ..
still why getting this no idea.
