Rooting the LG Optimus F5 (LG-P875)

Superuser! I miss you!
Superuser! I miss you!

Rooting the LG Optimus F5 (LG-P875) is a breeze with Motochopper. This rooting technique is specially developed for Motorola devices and because of this reason it is named as Motochopper.

Wait?! Motorola device? I was also in a WTF state for a while before I realized that the exploit also works for other brands like LG, Samsung, etc. For the techies, you can read up on how  motochopper works. Pretty neat.

Lets get on with the rooting of LG Optimus F5.

Warning: Rooting will void your warranty! Only proceed only if you know what you are doing. The author is sharing his experience in rooting the LG Optimus F5 (LG-P875) LTE non-camera and you shall not hold the author responsible if you damage your phone in the process.

 

Requirements

  1. Computer to execute Motochopper
  2. LG Optimus F5 (LG-P875) USB drivers from here
  3. Motochopper from the attachment in this post
  4. The LG Optimus F5 handphone
  5. A microUSB cable

 

Update on 28 June 2014
Towelroot (www.towelroot.com) is able to root the LG Optimus F5 (P875) easily. Do check towelroot out.

Installing the LG Optimus F5 USB drivers

First, before we proceed with the rooting, we need to install the USB drivers for LG Optimus F5 via LG Mobile Support Tool.

  1. Using a web browser, navigate to http://www.lg.com/sg/support/software-manuals
  2. Search for the mobile using the keyword “LGP875”
  3. Under the Downloads section, select the “Software Update” tab
  4. Download the LG Mobile Support Tool
  5. Install the LG Mobile Support Tool by following the on-screen instructions
  6. Launch the LG Mobile Support Tool once the installation completes

The actual USB driver installation starts here.

  1. On the left menu of the LG Mobile Support Tool, click on “Install USB Driver”
  2. In the Install USB Driver popup dialog, locate and choose “LGP875” and click next
  3. Follow the on-screen instructions
  4. You should see the following message once the installation is successful

USB drivers installed successfully!
USB drivers installed successfully!

Now we will need to turn on the USB debug for the LG Optimus F5.

  1. On the LG Optimus F5, navigate to Settings –> Developer options
  2. Ensure that “USB Debug” is enabled/checked
  3. Exit Settings

Test whether the USB drivers are installed correctly by connecting the LG Optimus F5 (powered on) to your computer using the microUSB cable. The Windows operating system should detect the LG Optimus F5 and the drivers should install automatically without errors.

 

Preparing the motochopper environment

Once the USB drivers are set up and tested, we shall proceed to download the Motochopper package and extract it to disk.

  1. Download the file “motochopper” highlighted in the Requirements section above
  2. Extract the contents to your hard disk (e.g. D:\motochopper\)
  3. Using Explorer, navigate to the directory that you have extracted the files (e.g. D:\motochopper\)
  4. Ensure that files are extracted (e.g. run.bat is present)

Alright, it appears that the environment has been set up and ready for rooting. Lets proceed with the rooting.

 

Rooting the LG Optimus F5 (LG-P875) using Motochopper

Great! You have set up the USB drivers for the LG Optimus F5, got your computer to recognize the LG Optimus F5 over microUSB cable and have got Motochopper on your computer. Do ensure that your LG Optimus F5 has got at least 50% battery before proceeding with the rooting process. You would not want the LG Optimus F5 to shutdown in the middle of the rooting process.

The rooting process should take less than 2 minutes and you will be notified once it completes.

  1. Using the Command Prompt, navigate to the location where you have extracted Motochopper (e.g. cd D:\motochopper)
  2. Ensure that you are in the correct directory by doing a directory list (using the “dir” command)
    You should see a list of files and one of them is run.bat
  3. Start the rooting process by executing run.bat using the command “run.bat” (and hit <Enter>)

    Starting the motochopper with administrative rights
    Starting the motochopper with administrative rights
  4. Follow the on-screen instructions
    You should see that the script is trying to exploit the phone and install superuser

    The rooting is successful
    The rooting is successful
  5. Your LG Optimus F5 should automatically reboot
  6. Once your LG Optimus F5 has booted up, install Root Checker to verify that you have root access

Congratulations! Have fun with your rooted LG Optimus F5.

    Managed to root the first time using this guide! thanks!
    But i stupidly reset my phone and i have not been able to root since 🙁

  • shadowandy

    Ivan,

    If you only did a factory reset, your phone should still be rooted. Try going to PlayStore and download SuperSU or superuser. Launch the application and proceed to do the binary installation.

  • Ashiya

    Hi shadowandy,

    Thanks again for your guide!

    I’ve encountered a problem– my cmdprompt stopped after “Pushing root tools”– it says “Success”, but doesn’t move on to/ display the next line of “[*] rooting phone”, etc. How do I prompt the next step? Thanks!

    Hi Shadowandy,

    oh, it started working! I think I hadn’t installed the most updated adb.exe before that.

    Thanks again for the guide 😀

    Apologies for yet another message– how long should the “Cleaning up” stage take? It’s been running for about an hour now… Thanks!

  • shadowandy

    Ashiya,

    The cleaning up stage should take less than a minute! Did you managed to get your phone rooted in the end?

  • Zach

    Just a question, is there any way to unroot the phone, if I need to bring down to service center?

  • Cyanogenmod11

    Have you try Custom Rom? CM11 ? Omni rom?

  • shadowandy

    Cynogenmod11,

    Nope, I did not try custom rom. Are they available? I felt that the factory rom is pretty decent hence did not have the need for custom rom.

  • Ivan

    Hi there! Need to seek your advise again. For SD card storage, must I reformat the memory card on my laptop before using it in LG, as the internal storage is insufficient and I have bought a 32gb card. Any option to shift or install the apps to SD card?
    Thanks.

  • shadowandy

    Ivan,

    For the SD card, it is best to use the LG F5 to format it although it is not really necessary.

    As for shifting of apps to SD card, there are apps like move2sd, app2sd, etc. You might want to check them out.

  • tactyy

    i get to daemon tools successfully running” but never progresses from there any ideas? never reaches the “found device” stage

  • shadowandy

    tactyy,

    Try using Towelroot. It should root the LG F5 (LG-P875).

  • john

    tried your steps but phone not rooted. why?

  • shadowandy

    john,

    If you are on the latest firmware from LG for P875. Use towelroot instead as mentioned in the 28 June 2014 update.

    Hope it helps.
