  GUIDE: ROOT SPRINT LG G3 LS990

Before you begin with the instructions below, make sure your android device is adequately charged — at least 50% battery of the device.

  STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be LS990.

Use Stump root only for the LG G3. Do not try this root method on any other phone of LG or of any other company’s device.

  STEP 1: BACKUP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.
