Root HOW-TO: Root the MetroPCS L9 (LGMS769)

[Swainsmith82]

I can't download the RootLelusICS.zip because my computer is detecting a virus in it. The modified bin file is also "temporarily unavailable".

I've spent countless hours already looking for a Metro PCS Optimus L9 root method and everything I find just has me running all over. I have faith in this one but I can't even get all the files... Could you email them to me? All I need is the ability to move apps to the SD card because the internal memory on this phone is so awful. Why they didn't make that an option when developing the phone beats the hell out of me. Please help me out here, I'm getting beyond frustrated.

This rooted me in five minutes...

[Allex86]

Since the phone you're seeking help on doesn't have its own thread on AndroidForums, your best bet is to ask in Guest Questions - Android Forums or perhaps another site with more details on your particular phone.

This forum is designated for the LG Optimus L9, not the Prestigio.

To root the l9 you should be able to use cydia impactor

To root the l9 you should be able to use cydia impactor

Thats just too easy! Confirmed it works..

 

[codeboy]

will this erase my contacts? im sorry to have to ask i just need to know ahead so i can back them up somehow.

and do i need a usb driver installed on my pc to do the cydia impactor thing?

nice video on impactor usage

=======================================
ok so this impactor method would not lose contacts it seems... but my phone i just bought a couple months ago and it seems the signature bugs were fixed so i will do the thread's method above, unless someone warns me otherwise. So if you have a brand new of this model the cydia method probably wont work.

Also if i do the main method above... i think that that wipes contacts but now im not worried i have them sync'd with google sync.

So... if there is any reason i should worry about the method the thread was about, please someone let me know so i dont brick my phone.

Thanks all, hopefully my exploration helps.

 

[codeboy]

also anyone know if this works LINK

Any solution for the app to SD? Is there any way to expand the amount of memory on a metro pcs LG l9? Please advise. Thank you.

It turns out that there's a PC app called Vroot which basically roots the MetroPCS L9 very simply. Their app actually claims to be able to root over 8000 Android devices. Quite amazing.
They even have an English version here: (sorry cannot post link here because am new to forum. Search for mgyun dot com vroot and look for the link to their English page.)

After it rooted my MetroPCS LGMS769 I immediately went to Play Store and installed SuperSU. When SuperSU runs for the first time it will detect that there is another root app on the system and ask to uninstall it which I did.
I then went in to Titanium Backup and at the very bottom of the apps list in the Backup/Restore tab there is an app with Chinese characters for its name. I made a backup of it and then uninstalled it.

If you get the security error and the phone will not boot you have to use the LGMobile Support Tool to do a recovery of the phone.

First off, let me preface this by saying there shouldn't be any difference between the Metro L9 or T-Mo's L9. If you have Metro's version, you can see on the bottom of the box that it actually says TMUS P769. The only difference is varying stock ROMs. Technically, you can use this guide on the T-Mo branded P769, but only if you want to run the Metro V10B version of the stock ROM (4.1.2). I recommend only Metro users follow this guide, but it's your choice.

Second, rooting or unlocking this phone is not easy. There's really no way around it. It isn't difficult if you understand the process. Unfortunately, a lot of the rooting/unlocking BL information is spread across many places. I will try my best to condense the information. FWIW, this is how I rooted the phone. I can confirm this method worked for me. The following will only root the phone.

USUAL DISCLAIMER: I AM NOT RESPONSIBLE FOR ANY DAMAGES (BRICK, UNWANTED SIDE-EFFECTS). YOU ARE DOING THIS AT YOUR OWN RISK!​

Generally speaking, this is the process we're doing when we root. We take LG flashing tools to flash the stock ROM (in KDZ format). While the flashing process takes place, all the files need to be unpacked before the flashing can take place. As the files are being unpacked (BINs), we're swapping one out with a modified version that allows the root.

First things first, we need the appropriate programs and files in order to do this process. We will need these things:

• Root package
• Stock ROM (KDZ)
• Modified Bin file
• USB drivers and text file

Getting Everything Ready

On your phone, go into Settings -> Developer and enable USB debugging. Then, go to Settings -> PC Connection and choose LG Software mode. Now, plug the phone into your computer.

Click the link to the root package. There are 2 zips inside the root package (RootLelusICS and RootLelusJB). Extract all folders from these zips. Once extracted, you should have 4 folders total (RootFlash, RootLelusICS, shttps, and RootLelusJB). Take these folders and put them in your C: drive. They have to be in the root folder of the C: drive. This is important. If they're not in the right spot, nothing will work!

Now, go ahead and download the USB drivers and text file. Go ahead and install the USB drivers, and open up the text file. The text will give the proper folder locations and the right info in order for the whole process to work. It's your choice if you want to use the text file. I will putting the same info in this guide.

Download everything else and put the files where you'll remember them.

Now, look in the RootFlash folder. You will need to run 2 programs:

• B2CAppSetup.exe
• msxml.msi

Allow both of these to install. Once they're finished, go ahead an close them.

Now, we need to prepare shttps. This program allows the LG flashing tool to work offline. We accomplish this by modifying our hosts file to redirect network traffic and spoof the program.

Open up Notepad as administrator (right click and choose Run as Administrator). When Notepad opens click File -> Open and copy/paste the following in the "Open Box"

C:\Windows\System32\drivers\etc

Look for the hosts file. If you see nothing, make sure to enable the option to see all files. Once it's opened, copy and paste the following into the file:

##Host Change
127.0.0.1 csmg.lgmobile.com
127.0.0.1 csmgdl.lgmobile.com

Save the file, and close it. You will need to restart your PC at this point.

Now, go back the shttps folder (we put it in the C: drive), and right-click https.exe. Click Properties. Look for "Windows Compatibility Mode" and make sure it's set to Windows XP SP3. (NOTE: this only needs to be done if you're running Win7/8)

Now, right-click https.exe again, and run it as administrator. Once it's running, minimize the program. Do not close it.

Now, go into the RootLelusJB folder (we put it in the C: drive). Run the rootL9 program. Now we should be ready to flash.

Flashing Magic

Go into the RootFlash folder (we put it in the C: drive). Look for UpTestEX_mod2_marwin.exe . Right-click it, go into properties and do the same thing you did for https.exe. Now, go ahead and run UpTestEX_mod2_marwin.exe as administrator.

When the program opens, ensure the "Type of Flash" is "3GQCT". Make sure the "PhoneMode" is "DIAG". Go ahead and select the stock KDZ that you downloaded. Then, go ahead and click "NORMAL WEB UPGRADE TEST" near the bottom of the window. Follow the prompts and choose your preferred language.

Move the flashing window out of your way. Open up a folder window and copy/paste the following location:

C:\ProgramData\LGMOBILEAX\Phone

When the flashing process reaches 8% progress, go ahead and go into the folder (you know the install is unpacking files when the text turns red). You'll start seeing BIN files start appearing in that folder. The files should look something like this:

LGMS769_AP[number here].bin

When you see LGMS769_AP[11].bin appear, copy/paste the modified BIN you downloaded at the top of this guide. Make sure it replaces the original file. Time is somewhat a factor, but you shouldn't need to rush. Just make sure that it gets overtaken.

Special NOTE: Some users (WinXP) will need to use the following folder location instead of the one listed above. All steps are the same, however, you will need to be in this folder location to see the BIN files:

C:\Documents and Settings\All Users\Application Data\LGMOBILEAX\Phone

After the flashing is complete, you should have a rooted L9. Enjoy!

Ending NOTE: If I missed something, please tell me. I will correct the guide. I haven't decided if I'm going to write an unlocking BL guide (as there's a solid video tutorial out there), but will consider it if people are looking for it.
