JUNE 2014:NEW GUIDE Easy Root Without PC + Unlock of LG L9 [No Fastboot] by CMahendra
- Thread starter cmahendra
- Start date
Hey @cmahendra, we have a few people who followed these instructions and ended up bricking our phones after installing CWM via flashify and are getting the "Security Error".
We can't even get Windows to recognize it. Installed LG Universal drivers and tried LG Mobile Support tool without success..
Could you please lend a hand and perhaps add a disclaimer/warning on the step where CWM is flashed via flashify as it seems to be causing trouble for some. Post is below.

This is for Unlocked Phone and already tried by myself several times. Instead of blaming me for my little contribution which failed for you, if you take a deep breath and do things right, you can still recover/unbrick your phone. This phone is literally unbrickable. Only thing is if you ask with some respect, many people will come forward to help.
BTW Did you read this warning on opening post?

Unclench. No blame. Just info.
In regard to asking respectfully, the manner in which I asked is about as respectful as it gets.

Newbie to Flashing...question on sequence of steps
MY LG L9 P769, I became sluggish, and was told to flash with custom ROM so here I am trying.
I am a newbie to this whole concept, after searching the forums and web, I cannot really find a guide to tell what to do in which order...so some questions, appreciate the experts response.
1. Will this guide for P769?
2. What is the sequences of steps to flash a custom ROM?
1. Unlock Phone
2. Unlock Bootloader
3. Root phone and install superuser
4. Flash a custom rom
3. My Device is P769, T-Mobile, and it is unlocked by T-Mobile....Do I need to unlock bootloader still?
4. The step 2 unlock bootloader applies for this P769 also?
Thanks in advance

Hi indyquad, if your bootloader is not yet unlocked (as I think) , this guide is not for you, this is not for unlock, it's for installing root and recovery in any L9 with unlocked bootloader (as the title says).
Cheers. Good luck.

This root method work on my wife's P768. After rooting she noticed that the battery is getting hot. I only installed Nofrills CPU and set the cpu to 300 as min and 1008 as max. What should I do or install to resolve the heating problem of the battery?
Thanks in advance
Thanks in advance

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.

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
Step 1) Preparations:-
- 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 @#!@# 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.
- 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!

HIT THANKS IF YOU LIKE THE INFO-GUIDE

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.
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...

Guide to Unlocked Bootloader (ULBL) of LG L9 P760/P765 and other variants.
=============================================
Things to remember while proceeding.
- IMPORTANT: You must have P760/P765 with P760 V20B EUROPE OPEN rom flashed on it ....or OTHER UNLOCKABLE ROMS. @Gh0sT.RPG tried unlocking on P765 V20B, V20C & V20D all unsuccessful. But He unlocked on P65 V20A Indian in just few mins.
How to Unlock Bootloader and do Easy Rooting of L9 P760/765/P768
Step 1) Preparations:-
- Download and Install latest LG Driver on Computer (This is for ADB drivers).
- Download and extract Android.zip on computer, preferably D drive. The folder "C:\Android" will be automatically created with all necessary files. (You can use D drive also in case of problems saving or running on C drive on Windows 8 or 8.1
- In Settings >>> Developer Options >>> Select check mark on for "USB Debugging Mode"
- In Settings >>> Security >>> Select check mark on for "Unknown Resources"
Now connect phone to pc with USB cable and change USB Mode to "LG Software Mode". Now your windows will install drivers and in Device Manager you will see following ADB PORT entry "USB Modem Phone ADB Port" (or some other words with name ADB).
Step 3)
Now wait for 30 minutes if you want to unlock bootloader (IMPORTANT Read post) and then open "Command Prompt" and give following commands in windows command prompt.
This should show the list of attached devices in ADB mode like shown below.
Step 4)
Now pass this command in "lower case" only because adb commands are case sensitive.
Phone will restart in pre-fastboot mode.
AT THIS POINT, YOU WILL UNLOCK BOOTLOADER:
You will get two options and to select UNLOCK you need to press VOLUME UP key which will unlock the bootloader permanently and when you press VOLUME UP key your phone is UNLOCKED and phone will go in FastBoot mode.
(*Sorry no screenshot available of these two options. Second option is something else I don't remember now, but forget it.)
Once unlocked this Unlock options screen will never show up in future.
Now you will see "Fast Boot mode" screen like shown below. But you don's have to do anything in Fastboot mode so just Remove USB cable. Remove battery and reinsert battery and you may start phone normally.
You are done! Your LG L9 is now with Unlocked Bootloader.

I tried Mobile Uncle Tool, it could not flash any recovery. So did try Flashify latest version and it worked.
Though I did not try TWRP but it flashed all CWM versions I tried. Thats why added four variations. One version without Touch. Technically it should flash any recovery, including Philz too.
You tried LGPwn a year ago and obviously it was working for few modesl only. I tried this with latest LGPwn, which I guess is February/March 2014 version. With obvious reason it will not work on Locked bootloader. But you have P760 so you have change to unlock it but first flash old stock rom, as mentioned in 2nd post in this thread and also in my other old thread.
Unlocking Bootloader was possible on only few versions of ICS/JB. Flash ICS V10D then unlock and then try this rooting and installing recovery. Should work. Once you have installed Recovery, you can do anything with this phone
Now fastbook is history, not required at all.
Press thanks button if you like this information.1
Thanks
Actually my OFFLINE FIX FLASHING method is easiest of all. Only problem with people is the SEQUENCE ERROR. I can still guide you if you post your problem in that thread. I thing I should make some changes in that thread by changing few words or lines where possibly a confusion arises. If interested post your query which step you find it difficult or error.1
I am asumming you have P760/P765 and its good sign that you did everything perfect until "oem-unlock" command.I have managed to flash V20B Open Europe to my P760. (ROM is from this thread ) Could not find any other KDZ.
Now I have restored my device to factory settings just as you said in other thread and this fixed all system apps that where broken.
Following that I pluged it in and waited for half an hour. Then started cmd and entered all of the commands (adb devices detects my device and Device manager sees my phone as ADB Interface > AndroidNet Sooner Single ADB Interface.) Now I started adb reboot oem-unlock. And it restarted my device but just that it did not go to prefastboot menu or anything similar just regular reboot. I read your old thread on this and cannot find problem.
That's strange to see its booting normally. That means you are not getting fastboot mode also, as shown in screenshot? Your BL seems still Locked but there could be some other issue with bootloader. Try with ICS rom. See if the link of ICS are or not. I forgot exactly which V10 version worked for unlocking bootloader. Read old thread carefully.
Some other devs are claiming they can unlock bootloader with different method. Try that too. - READ AND FOLLOW ALL STEPS CAREFULLY
