How to Root LG K20 Plus using SuperSU

Thanks to Chainfire, most of the Android based devices that are available on the market can be easily rooted. Well, among these devices we can now include the LG K20 Plus. So, if you were already thinking that an unlocked Android system should make things easier for you, now you have all the reasons for following and applying the guidelines from below. As I have already outlined, there you will be able to learn how to successfully gain root access on the LG K20 Plus.

The LG K20 Plus isn’t a high-end smartphone, but that doesn’t mean you can’t enjoy a stable and a smooth Android experience all the time. In fact, if you choose to apply this tutorial you can even succeed in improving the general performance of your phone – you can bump speeds, optimize and customize built-in features and capabilities and even personalize the Android UI. Everything is possible because you will gain full control over your LG K20 Plus internal system.

And root access is exactly about endless accessibility. Once this process is applied the Android OS will be unlocked – all the factory and default restrictions which are there by default will be removed. Therefore, in the end you will be able to tweak your Android device for obtaining better results from its system. And the most important operations that can be initiated on a rooted handset are: installing apps from other sources than Google Play, flash root-only tools, add new features and apps that aren’t pre-loaded in the stock Android firmware, update with a custom ROM like Linage OS, AOKP or Paranoid Android, add custom kernels and custom MODs and even overclock or undervolt your Android device.

However, getting rid of built-in restrictions is not a process supported by your OEM. Unfortunately, the root exploit that will be used is developed and offered by third party devs and not by the LG team. So, you have to assume a risk – losing the warranty of your phone. Yes, this is going to be an unofficial process and the warranty of your LG K20 Plus will get void – you can afterwards try to restore it but only by choosing to re-flash the stock Android OS, situation during which the root access will be revoked.

During root your data might get corrupted or a full wipe might be initiated. Shortly, everything that’s not there from day one might be erased – contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data and more. As a conclusion, you shouldn’t start the steps from this guide unless a backup has been already applied. Don’t worry, saving your personal files is easy because you can sync your files with your Google Account, you can use backup and restore apps from Google Play or you can smartly manage built-in cloud storage services.

And that’s not all. A set of preparation tasks must be reviewed before you begin the root process; here you have the essential pre-requisites:

  • Unlock the bootloader of your LG K20 Plus – you can gain root access only if you first unlock the bootloader that runs on your phone (that’s the first unlocking process that must be applied on your device).
  • Install TWRP recovery on your LG K20 Plus – the SuperSU root exploit is a .zip file which can be installed on your phone only if a custom recovery image can be used.
  • On your smartphone you need to gain Developer Options – this feature can be enabled if you tap repeatedly on Built Number: tap until you receive the ‘you are a developer’ message.
  • Next, from Developer Option (you can access it from menu – > settings) you must check the USB Debugging option.
  • This is a manual operation; a computer and your smartphone is required – of course, a connection between these devices will be also implied.
  • The power that’s left on your handset should be higher than 50%. If the power is too low your smartphone might get turned off in the middle of the root operation.
  • If a sudden turn off occurs, your phone might get soft-bricked: different malfunctions can be caused within the Android core system.
  • Therefore, plug in the charger before resuming the steps from below if that’s required.
  • Apply this tutorial only if you own the LG K20 Plus; if you have any other smartphone, try to use our dedicated root step by step guides or try to apply a general root solution.

How to Easily and Safely Root the LG K20 Plus using SuperSU

  1. Start by getting the SuperSU package compatible with your LG K20 Plus. You can download this file from here.
  2. Of course, save the package on desktop.
  3. Afterwards, power on your phone and connect it with your computer with the help of the USB cable.
  4. From your computer copy-paste the root exploit on your smartphone and when that’s done unplug the USB cord because the computer is no longer required.
  5. Switch off your LG K20 Plus, wait a few moments while the shut-down process is completed and then reboot recovery mode on your Android device.
  6. From recovery tap on Install and then load the root exploit file.
  7. Swipe in order to begin the flashing process and wait while this operation is completed.
  8. When done, go back to main menu of recovery and tap on Reboot.
  9. If during this reboot your K20 Plus is getting stuck in a boot loop, follow: return to recovery and initiate a full wipe – just select “wipe data factory reset”, followed by “wipe dalvik cache” and by “wipe cache partition”.

There you have it: that was the root operation that can unlock the Android OS that powers your LG K20 Plus.
