If you want to root the LG V10 smartphone and not necessarily install a custom recovery on the device, we suggest installing the ROM Toolbox application from the Google Play Store. The ROM Toolbox application by J. Rummy comes with the option to create NANDroid backups, just like you normally would from something like TWRP Recovery. Those of you planning on taking NANDroid backups with the ROM Toolbox might also be interested in investing some time installing the NANDroid manager application. With the NANDroid Manager, you can ‘manage’ those backups you took by restoring partitions of them at a time. That means you do not have to restore all the data you backed up at once. A great app if you took a full backup with the NANDroid backup feature and only want to restore something like your apps, for example.

Anyone wanting to install the ROM Toolbox or the NANDroid Manager apps we mentioned can do that after they root the LG V10 smartphone with the F600L model number running Android 5.1 Lollipop after the break:

Files You Need

  1. Download the rooting exploit you need from this link.
  2. You are choosing to void the warranty of the LG V10 when you follow this guide and root the device. Like you know, rooting is unchaining the operating system and breaking away from the LG restrictions. On occasion, some mobile networks can allow rooting. You’ll need to make those inquiries for your mobile provider.

Rooting the LG V10 F600L running Android 5.1 Lollipop

  1. Enable the USB Debugging Mode on the LG V10 smartphone before going further. You get it done by pointing to the V10’s Menu > Settings > Developer Options > USB Debugging Mode.
  2. Any V10 owner who does not see the Developer Options menu can unlock it so it’s no longer hidden by tapping on the Menu > Settings > About Us > Build Number seven times. The V10’s operating system will eventually tell you that you are using the device as a developer if you keep tapping. That means your V10’as Developer Options menu have been made available from the Settings and you can now follow the step above.
  3. Boot the LG V10 to bootloader mode and connect it to the computer with the USB cable.
  4. Run the LG Up package on the computer.
  5. Select your V10 smartphone from the menu of the LG Up.
  6. Wait until the flashing is complete and then you’re all done.

In conclusion, that’s all you need to root the LG V10 with the F600L model number. You can confirm the guide did work for your device by installing the root checker app on your V10 from the Google Play Store. Open your root checker application on the V10 and agree with any updates, and to grant SuperUser access if requested. The following screen will let you know if your V10 handset is rooted. Further, you can keep the root checker app on your device and check what it says after you unroot if you ever think you might go down that path.
