Hi Pedroffs, yes, when I did the root I already was with the version 20h, - I rooted it with the

LGPwn_1.0.apk and much more later opened the bootloader following this tutorial -

You're welcome, yes, I followed this tutorial successfully for unlocking the bootloader and for installing CWM recovery (I'm on artas182x's CWM 6.0.3.5 recovery).

Cheers. Good luck.

Banggg!!! :D

I don't know as I am new here, but may be the steps look quite confusing in these forums, but they are very simple... :good:

Ok. So Now I can take normal breath, as successfully done the procedure... :)

I have done this on my L9 P765 V20C indian version... :good:

So I did:

Installed fastboot drivers using omap4boot

Unlock using ADB

Came into Fastboot mode

tried: fastboot devices and got No Devices attached

I saw that Device Manager of Windows is showing Android device.

So, updated that device's driver with omap4boot driver

tried: fastboot devices and yes.. My device is attached now :laugh:

Flashed recovery using fastboot, i.e, fastboot flash recovery recovery.img

Rebooted into recovery using Vol(+) + Power + Home

Installed Zip from sd card

Thank you very much for this Guide :victory:

That was really easy. But, now I am confused that how to use this CWM to backup my phone and install a custom Rom :confused:

Hi :)

Can i do this proces if LG L9 p760 is on ICS 4.0.4?

And how can I enter in bootloader on LG L9? Its not like on my nexus 4 :/

I'm doing unlocking for my friend :)

OK i realy need some help :) i updated first L9 to jb...V20H Europe Open

I followed all the instructions, instaled drivers everything looked fine.

when i go for

adb devices i get recognised device

when write command

adb reboot oem-unlock

the phone just reboot system and nothing happens....
[LG Optimus L9 P760, P765, P768, P769] thakurbhai:
When I did it, then I had to install the fastboot drivers 2 times. I had to follow this process:

adb devices command

Device got detected!

adb reboot oem-unlock command and I got rebooted into LG Fastboot Mode, i.e, this screen

fastboot devices command

No Device Connected

Installed the Drivers again using the omap4boot method

fastboot devices command

Device Connected!

fastboot flash recovery rec.img command to flash CWM.

Flashed CWM successfully!

Back Up Stock ROM into External SD

Flashed Custom ROM from External SD and Enjoying :victory:

I wish it could be helpful... :good:
[LG Optimus L9 P760, P765, P768, P769] Gradjevinac:
well i can''t get trough this step...

When i write adb reboot oem-unlock phone just reboots to the homescreens... its not going into fastboot mode...

and drivers are instaled....

thanks anyway for reply ;)

Myphoneis recognized wheb conected as adb device

when i conect it turned off without battery its recognized as fastboot device

but when i turn it on and conect with laptop and write

adb reboot oem-unlock

it just reboots with lg logo and goes to homescreens.
[LG Optimus L9 P760, P765, P768, P769] thakurbhai:
So, did you tried installing the Drivers again, as said in Step 14 in omap4boot method?

I remember that I had to install the drivers again without the battery. Its all something related to the drivers here. Please try again.

Remember, as soon as you are in Fastboot mode, try this command:

fastboot devices

If you can see your Device, you are done with drivers. Now you can proceed to Flashing recovery with fastboot flash recovery recovery.img.

So, overall, try installing the drivers again. :good:
[LG Optimus L9 P760, P765, P768, P769] orzeh:
Hello

I have the same "problem" like Gradjevinac

everything is installed but i cannot continue after step

adb reboot oem-unlock

phone just reboots to the system not to the screen with "unlock bootloader"

drivers are installed twice, without battery is like Gradjevinac wrote.

maybe this is regarding phone software:

[LG Optimus L9 P760, P765, P768, P769] thakurbhai:
Make sure that your devices are Up to date, i.e, Android Jelly Bean 4.1.2.

I have done this on JB and read somewhere that it doesn't work on ICS. If you update to JB, then you should let the phone be normal upto at least 30 mins or an hour, before starting this process.

Otherwise, you can search the forums for tricks regarding Unlocking Bootloader.

Hi,

i have the same problem who have other people, unlock the bootloader, but i have a question

phone don't reboot to fastboot automaticaly but i can run fastboot manually,

do i brick the phone when i try to flash recovery without unlock the bootloader,

my phone had a sim-lock but it was removed in service, i had the neo v and removing sim lock give me a unlocked bootloader.
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:

May be not! Chipset different so Bootloader also be different. Do not try if you do not know how to unbrick your model.

[LG Optimus L9 P760, P765, P768, P769] BajoPrimate:
Hi Abazel, you need an open JB (the Orange's one is not valid for this!).

Read the OP carefully, all you need is there: valid KDZs, offline flash tool, fastboot drivers....

Anyway, explain here all you've done (detailed) and you'll get help if needed.

i followed preparation step.

Then i gave:

adb devices

and it listed my device correctly

then:

adb reboot oem-unlock

just restarted my device, and so did: adb reboot-bootloader

so i can't get to step 2.

Do you think i should flash V20H_00.kdz and retry?

if your phone boots then surely you have adb drivers installed properly. But if its not going in fastboot mode, then something wrong here.

Are you sure you have unlocked bootloader? Open Phone Dialpad and type "3845#*768#" without quotes it will open "Hidden Service Menu" and see for "Bootloader Unlock Check" option and find the result. It should show "Unlock" like shown in this screenshot.

[LG Optimus L9 P760, P765, P768, P769] cmahendra:
Hey you have UNLOCKED bootloader. sw upgrade mode also shows it. Are you sure you are using hyphen (-) sign in "oem-unlock". Some people used space instead of hyphen.

PS: I may be wrong, but have you installed BUSYBOX in "/system/xbin" folder? If no, do it with "smart install" option in the app and then try adb again.

You also need to manually unlock your bootloader by following this thread here.

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

I see what the problem may be, I followed the guide posted on here about fastboot with omap4boot. Now when I load up SD maid, it says my device is a 'U2'. I think I've tried too many things out at once. I think I'm going to backup with CWM, and fully refresh the phone. When I plug the phone into my pc it comes up as a P760 - which is odd.

And then i click no and nothing happends, it says Sorry! until cwm recovery is available, rom manager will not work with lg-p760!.

Are there any other ways to easily instal cwm and root?
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
It is strange why RomManager does not recognize L9 P760 for you. Are you sure you are on Stock P760 Rom? which country?

In fact you can see the CWM for EXACT P760 on thier official download link http://www.clockworkmod.com/rommanager (look for LG Optimus L9 and download file for P760) You will see same file for P760 I have uploaded in OP.

But keep it aside for the moment.

Yes, there is other way to install CWM in FASTBOOT mode, you will need Fastbood drivers. You said you have unlocked bootloader, then you should be able to put phone in FASTBOOT mode and flash CWM

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

EDIT: I have completely removed ROMMANAGER method, as it is reported not working on another P765 my friend have. Will collect some more information and will update. But meanwhile I have made changes in FASTBOOT mode rooting in OP.
