HOW TO ROOT LG OPTIMUS BLACK

  1. Download the Gingerbreak exploit from this link [3].
  2. Drag the Gingerbreak from its default download location over to the desktop of your computer.
  3. Connect the LG Optimus Black smartphone to the computer with the USB cable and copy the Gingerbreak APK file over to the root of the SD card internal storage.
  4. Open ‘My Files’ on your smartphone and install the Gingerbreak APK so it turns into app form on the device.
  5. Launch the Gingerbreak app by tapping over the same and then tap the ‘Root’ button you can see from the main page within the application.
  6. Exit the app and reboot the smartphone before doing anything else like entering the Google Play Store.

You should now find the Superuser app available from your app drawer. That same Superuser app is incredibly important to your device. It’s the app that is granting root access to the app you want to have root aces to work. Furthermore, it’s also stopping any apps from automatically having root access to the internal system. That means no virus or malware can jump in your system unless you tell Superuser it can.
