Rooted my P768f (V10D - Thailand) by downgrade to P768 (V10A - Vietnam). But don't do factory reset, cannot connect to 3G after factory reset (Edge only). Just flash V10A and root it after phone reboot.
I also try update to V10D again (change my phone model back to P768f) but root is gone.
Perfect!!! I follow the downgrade guide to 10A and the root and all went smooth!!! Well done!!! P760 , voodoo root keeper and update to 10e rooted!!!
Can somebody help me? Im an italian boy so i dont understand all you wrote in first page, especially i didnt understand where i have to extract the RootL9.zip...what does it means "extract to root of C"??
I wish to ask you a question.
I have a Lg p760 branded by ''Tim'' with fw V10B (P76010b-222-01)
I tried to flash The open Europe fw V10A without any brand but after flashing this V10A_00.kdz
I got that my phone was downgraded to V10A and seems to be unbranded but when i look for OTA update it says i'm running the latest version.
I think it's linked to the code P76010a-222-01 that prevents the phone to find OTA , Lg tool finds the update but if i'll try it i'll came back to brand ''Tim'' Version.
Do you think is possible that Lg kdz flasher recognise the S/N of my phone and give the Fw the -222-01 extension?
Do you think is possible to overpass this by following your guide?
Thank you :victory:
Please inform which variant of L9? Which rom you downgraded and rooted. The information can help some more people.
unzip the zipped file to C drive. It will create a folder as Root and there will be files inside the folder.
How the hell should I explain in more simple english than this? sorry I dont know italian.
Can i unzip it on the desktop?! And in this way what i have to put into prompt command?
Lolz. Its better to listen good old wise people, when they stress on some instructions.Can i unzip it on the desktop?! And in this way what i have to put into prompt command?
i thank you for all time you are wasting with me, but when i put the line of command promt(cd \C:\Users\Name\Desktop\Root) it gives me an error: "The filename, directory name, or volume label syntax is incorrect"! What i have to do?

hi guys, new here but I would like help with the flashing process.
I followed all the steps and opening gives the following attached image.
then I opened UpTestEX_mod2_marwin as admin, set 3GQCT, emergency mode and selected V10A_00.kdz.
after start updating in normal web upgrade test, a popup appears saying "Checking for new LGmobile update program" that loads up something that looks like the attached image instead of prompting me to select my language and country.
the program then loads looks something like the attached, but with my phone connected it says that my phone is of the latest firmware and does not need updating and hence, I AM STUCK.
Please help me anyone?
As per screenshot it seems that your LG Support Tool is still able to connect internet.
@ALL
Please note, I have merged first two steps into one and made it more easy to open and save notepad program after necessary changes.
Your small server is working fine as it is showing that fake webpage. But it looks like your HOSTS file is not updated with this line as mentioned in STEP1.
As per screenshot it seems that your LG Support Tool is still able to connect internet.
Try adding adding a line, close HOSTS file and reopen it to see if really you could add this line or not.
Disabling Internet also may help at some extent. Internet is not required at all for this flashing.
Thanks for the response.
Well I already added the line in the hosts file. Turning off the internet didn't help cuz the program wouldn't work without internet connection. It when clicking upgrade start, the program gave a pop-up saying please check your internet line and it asked me to restart or cancel. Nothing else happened.
Any other ideas as to why the program could still contact the server? Thanks!
Hi cmahendra,
First, let me thank you for your contributions here. I am a very new(2 days old) android user and my first android phone after Nokia E71 is LG optimus L9. I brought it for its features vs price factir and till now am very pleased with it. The only concern I have is its internal memory being just 2.33GB and if I am to assume right, there is no way to expand this or use the external sd card without rooting the phone.
Hence, searching for option brought me here and am glad to see people on this forum taking so much initiative to help others and design innovative features/products.:good: :good: :good: I have gone through your current post to start rooting (though I dont even know what flashing ROM or KDS means ). i realize that i have V10d and your rooting tut clearly states that rooting method wont work over 10d. How do I go about rooting my device now?
Secondly, after I root my device, would the phone have the same ROM that it came with or do I have to put on some custom ROM?
Thanks to all developers and contributors: Bin4ry , adixtra , unknown_world. I thank to all the users of this thread who gave feedback and reported issues time to time, which helped "us" to make this guide better and perfect.I see almost everyone in L9 forum is giving reference link to this flashing guide in their threads, but almost no one is mentioning any credit to this. They are just putting links. What do you all think, pals? Do I deserve a credit or not
Please note the opened file name is only "hosts" and does not have file-extension like txt or anything.
Now SAVE file and Close it.
7) Execute "UpTestEX_mod2_marwin.exe" with "Run As Administrator" option and in Windows Compatibility Mode with "WindowsXP SP3" (must for Win7/8) >> and Select your KDZ file. Select "3GQCT" in Type of Flash and select "EMERGENCY" for PhoneMode. Ignore all other options and press "NORMAL WEB UPGRADE TEST" at bottom. This button is very light and hard to see at first attempt.Post-JB issue: If you have installed JellyBean before, Phone may not go in "Software Upgrade Mode" or Flashing stops at 14% in 11th step.
Then do this WORKAROUND: Keep the Phone POWERED ON with USB connected and on "LG Software" mode and do next step of flashing KDZ with Update tool and the phone will automatically go in software upgrade mode.
FLASHING ERROR AT THIS POINT? If you have installed JB before then your flashing may stop at 4% to 14%. This may be due JB rom already installed before or due to driver not completely installed for "SW Upgrade Mode".
WORKAROUND: Cancel flashing by exiting LG Update Tool. Phone should be still in SW Upgrade Mode, Remove USB Cable, wait 10 seconds, Insert USB cable again and let all drivers install for this mode. The device manager should look LIKE THIS SCREENSHOT. START AGAIN FROM STEP 6 (Read about Post-JB Issue)
Rooting ICS ON LG OPTIMUS L9 (OLD BIN4RY METHOD) Only for ICS.Before we start please remember, Use information at your own risk.
great work, but i do this tutorial for root in my LG p765 from indonesia and its not work. The phone wont restart after i click restore.
My phone has already had 10c when i was buying it. Or i must install 10c kdz from the link you gave it?
thanks before:good:
ok one thing that was missing after all the hassle was the automatic offline procedure which you must run with command prompt after setting the hosts up and turing on the server as well you must start the windows enabler as a administrator attached is the missing file just rename it without the .txt to use it in command prompt
