Default [updated] Root T-Mobile LG L9 (P769)

Prerequisite:
  • You must install LG United Driver (simply change the phone USB mode to LG mode and install PC Suite).
  • You must enable USB debug mode (in developers option) and "unknown sources" (in security option).
  • Download and unpack Root and Restore.
    http://forum.xda-developers.com/showthread.php?t=1886460
  • Download the attached RunMe_L9.txt and change the extension to .bat, and put it to where the unpacked folder is.


Are you ready? Here it goes:
  • Hook up your phone and choose USB LG mode. Make sure you see a bug on the top-left of screen.
  • Open Root and Restore folder->run RunMe_L9.bat
  • You will be prompted to restore data. Look at the phone screen and choose "restore my data" when prompted, and press any key after the restore has finished.
  • The phone will reboot. Check the terminal window and check for "(are you rooted?)" error. If there's no error, check the phone to see "Android is updating". If so, the phone should be rooted.
  • Download and install busybox and SuperSU.
  • Done.

Happy Rooting!

It works just fine!(L9 P760 EUR). One or two things you have to pay attention:
- Root BEFORE the OTA update, most have the 10a firmware version, it's still doubtful if this method works 100% with later fw.
- After rooting install Voodoo Root Keeper so you can preserve root after update.

I have, with couple different root versions multiple times. My 10e phone just won't take it, and I didn't even get a chance to try a 10a-d version as they are selling them with 10e installed now.



Nevermind- this version DID work for me. The other versions I tried did not fully stop the restore tool thus restarting too early before the files could copy.

This version worked perfectly though, even on 10e. Thanks to all who worked on this. I hope this phone becomes very popular because it's been great so far! Can't wait to clean it up and see how it shines.

Default worked for me

So, i renamed the file like i was suppose to but it didnt change the format to a .bat i had to open the .txt and edit and re save it as a .bat and it worked! i ran the .bat and wahlah! my phone became rooted. I am having trouble with the pc suite seeing my phone. and I still do not know how to save any apps to sd card. and that was my main goal in rooting. maybe i need more practice.

Default Won't even connect to PC Suite

I got the PC suite installed, but when I try to connect my phone in LG Software mode, it keeps disconnecting and reconnecting constantly (seriously once every 5-45 seconds), and meanwhile PC suite tells me it failed to connect to the phone. Windows 7 / P76910e. Anyone else have this problem and get it fixed?

jims89 - try a different USB port. If that doesn't work, do a google search for lg optimus l9 drivers and go to the link to LG mobile support (should be the second link after search)

carmine92207 - no recovery rom in the works for this phone...as of right now. locked bootloader and no devs working on figuring out how to unlock the bootloader that I have been able to find out.

Just ignore this, you don't really need to connect your phone to the program. Its the drivers the programs installs that you actually use to root. My phone did the same thing and it rooted just fine.

Sesameopen - if you're asking if you should run in normal or special, you should do normal. You shouldn't run into any problems if you're running the newest script.

Hi,

I am getting to the process until it says:
----------
Please look at your device and click RESTORE!
If all is successful i will tell you, if not this shell will run forever.
Running ..
=========

my device prompts me to restore. when I click on "restore my device", I get a "restore starting" message and then "restore ended", and the command prompt gets stuck at this point (running).

any suggestions?

This same thing happens to me ONLY on my Win XP PC. I cant copy to my phone, but I can copy from. Now on my Win 7 laptop, all I need is the phone drivers, I dont even need the Suite and it still works (copy and paste to/from the phone)

I have TM P769 with "e" firmware. I am getting "The system cannot find the path specified" messages when the script tries to push the files (busybox, su, Superuser. etc.). The script has "/data/local/tmp/." for the destination directory. I see this directory structure on the phone -- "Computer\LG-P769\Internal storage" -- and no data subdirectory. I am guessing that is why the script cannot find the path. I am running the script from a folder on the Windows 7 Desktop. I am using the new, renamed L9 bat file.

EDIT: I think I am OK now. After reading another post I opened the "stuff" directory on the PC and ran the adb.exe file. It opened a window, ran a quick script and closed. After that the L9 bat file ran with no "path not found" messages -- and the SuperSU app was installed.

Default Re: [updated] Root T-Mobile LG L9 (P769)

Okay, I have been at this all day, so I'm just going to break this down for you guys:

*I am a beginner, but I have a little experience (if this makes any sense).*

Goal - root phone, remove pre-installed bloatware, and download and use the free WiFi tether (that requires the phone to be rooted, of course). [Side note] If there are any custom ROMs available for my device (the LG Optimus L9 [T-Mobile prepaid]) then I may try those, too, but I'm cool with the phone as it is; I just need to tether my 4G to do homework on my computer.

Now, my device automatically installed its drivers onto my Windows 8 computer after connecting it and selecting the "LG mode", so I have that down pat, I believe. I have also downloaded the RunMe_L9.txt file, opened it, saved as ".bat" (literally just .bat; nothing else), and ran the file as an administrator, but all I get is a bunch of "path cannot be found" followed by "press any key to continue", ending with "after your phone reboots, you will be rooted. Enjoy." The problem is: my phone didn't reboot, I am still not rooted, and I'm certainly NOT enjoying it.

So, I'm thinking it isn't working because I don't have that Root and Restore file downloaded and extracted, but it just seems null at this point since I'll only be opening the RunMe file, right? Also, if that's not the case, how am I supposed to download the required files with NO internet? I downloaded them on my phone and transferred them to my computer, but, for some odd reason, the Root and Restore file isn't something I can "extract" and/or "unpack". So, what am I to do? Does anyone have any suggestions? Please respond as soon as possible, but at your earliest convenience.

Thanks in advance,
D.

so I ran the runme.bat then it went through all the steps it said my phone was going to restart and it never it. I am restarted and tried 8 times so far. I know I may be a noob but can I have some help.

alright, go into settings, about phone, software information, the software version should read something like p76910g. if it's anything before 10g, you should be able to root it.

How risky is this method? I have no money left to replace it if I brick it. Yes, I am a tad paranoid about new devices.

all you really risk is a minor waste of time. if it doesn't work, it does absolutely nothing to the phone.

Just making sure. I'll give this a shot.

EDIT: Root achieved! Thank you all. How might I go about deleting T-Mobile crapware? On my triumph I flashed CM9 right after I rooted and installed recovery, so I never had to learn how.

EDIT 2: nvm link2sd has an uninstall option. All who are rooted give this a try:

It made a modest difference for me.

Default P76910e for me -- What now?

Okay, it's showing as P76910e. What do I do from here? In fact, can anyone with the exact steps (with the exact software version) even attest to rooting their phone with this process? If so, can you please give me a detailed step-by-step run-down of how exactly to do it? I really, really need to utilize the Free WiFi Tether (for root) app so I can get my classwork done by the 30th!

Remember, I have fulfilled all of these prerequisites, so I am going to need either a new method or someone needs to explain what it is I am doing wrong by detailing exactly how it is supposed to go.

Thanks in advance,
D

*Edit* IT WORKS!
I guess the problem was that when I downloaded the prerequisite files from my phone and then transferred them to my computer, it was incomplete in some way. I was able to extract and run them appropriately when connected to my neighbor's Wi-Fi (shh). Thanks, guys!

To remove bloatware get Titanium Back up. If you are torrent friendly then you can find the pro version online in apk format for free. That allows you to freeze programs from starting and there is no need to remove them.

Default Worked but now theres an update

This worked great for 10e but now 3 days later my phone wants to update to 10g. I know this will kill my root and possibly my chances to root again. I cant seem to find a safe way to block the ota updates. Any idea that is not a real brick risk? Thanks for the help

I was able to keep my root after doing the OTA update to 10g, all I did was before I updated installed voodoo root keeper, backup my root with it, then updated to 10g, after the update I went back in with voodoo and chose to restore root then VOILA i am now rooted on 10g with my p769

This sounds good and I will try. Do I need to do the temp unroot right before I do the actual update?

I did not select temp unroot when i did it. Just make sure it has the backup of your root! When it reboots after updating, head on over to VooDoo RootKeeper and select Restore Root. Congrats your on 10g and rooted!!!!

Thanks for all your help mjb1994. It did not update but I do not get the ota update promts anymore. When I tryed update after backing up the root it gave me an error about google something. I realized that I had to probably unfreeze all google stuff(which stilled showed frozen with titanium pro during supposed unroot) and tryed to update through the phone. My phone said it was up to date and is oddly still on 10e. The update prompts that shwed up every 30 min have not shown up almost a day later. I am happy with this so thanks!

Just saying that the Voodoo OTA Rootkeeper app on the play store does indeed allow you to keep root after the 10e to 10g update.

I wonder what I'm doing wrong then...
I am rooted and my root is backed up on voodoo ota root keeper, but, yesterday, when trying to restart and install the update, I was presented with an upside down android with a red triangle hovering above him.

I did some scouring online to see if anyone else had this issue and I found nothing. I did find that it's people with other phones were having similar issues, though, and it is/was because they didn't have a system/custom recovery. I don't even know how to access the recovery (boot into it), nor do I know how to obtain the update again.

I'm currently running v10e, and this version doesn't allow me to tether my 4G (meaning I have no internet access on my laptop, and everything I have to do online has to be done from my phone--including homework [which sucks]). The v10g update resolves this issue, but I can't access it!

Does anyone know what I should do?

Default p769 10g

I stupidly hit the update button before reading this thread didnt have voodo installed and no more root access. any other work around? I've been seaching my a## off and nothing. I woldnt have to root if they didn't take away the capability to run files from sd. Well thats a lie, I'd probably root anyway. lol
