How to Unroot LG G3

The best when having an Android device is that you can anytime choose to tweak your smartphone or tablet in order to unlock its system for improving the performances and customizing the OS. Well, as you can tell, on your LG G3 you can perform various custom operations and by starting with the root procedure you can begin your customization and optimization procedure. Now, due to different reasons you might want, at some point, to restore your LG G3 back to its initial state, thus revoking root access will be a must. So, because of that, during the following guidelines I will show you how to easily unroot any model of LG G3.

As we all know, by gaining root access (by the way, you can anytime learn how to easily root your LG G3 by using our compatible tutorials) you will perform an unofficial operation since your phone’s internal system will be unlocked – all the factory and default restrictions will be removed. So, by rooting you will make unauthorized changes, thus the warranty of your LG G3 will get voided. Of course, after ensuring root access you will be able to take full advantage of your phone as you will be able to update it with a custom ROM firmware, install a custom recovery image on your device, flash a custom kernel, remove bloatware and lot more.

Unfortunately, since the warranty is lost, if you somehow manage to soft brick your LG G3 you will have to pay for the technical and official assistance (basically you will have to try to unrick your Android device by yourself as taking it back to service will imply in spending some money). So, if you have managed to brick your device and now you are trying to bring your LG G3 back to stock, the unrooting will be a must. Furthermore, the unroot process will reinstall all the factory and default restrictions on your device so you will be able to take your phone back to its initial state.

Moreover, on a rooted handset you will not be able to receive OTA updates – the updates can be installed manually though. So, in case you want to go back to stock for receiving the OTA releases, you will first have to unroot your LG G3. As you can see, unrooting and relocking your Android device is as important as ensuring that you can customize and optimize your handset; therefore the best will be to bookmark this step by step guide as who knows when you will need to use the same.

Now, as you will see during the steps from below, unrooting your LG G3 will imply in downgrading your phone to stock Android firmware, which means that this tutorial is revealing an official procedure and not a custom one. All this is possible thanks to those of xda-developers who have provided us with the Flashtool and with compatible stock LG G3 firmwares – this tutorial is compatible with any model of LG G3 so you have nothing to worry about as long as you flash the proper software (else you can mess things up and you can even end up in damaging your handset).

Of course since we are dealing with an unofficial process, if possible, you should backup your data before starting the unroot procedure. Basically you should take care of the personal data, info and accounts that are saved on the internal storage of your LG G3. So, use cloud services or backup and restore tools for saving your contacts, call logs, market apps, images, videos, contacts list and everything else you might need afterwards. It is also recommended to make a Nandroid backup in order to avoid unpleasant situations from happening.

A computer will be required as you will have to download the required files on the same; at some point a connection between your phone and your computer will have to be established, so your phone’s USB cable should also be near you. On the computer you are using the best will be to temporarily deactivate the antivirus, antimalware and any other security protection, or else these programs might interfere with the unroot process. On your LG G3 the USB debugging option must be enabled from path “menu – settings – developer options”. Moreover, on your handset check the battery status: if there is less than 50% power left, charge your device before doing anything else – if your LG G3 gets turned off in the middle of the downgrade operation it might also get bricked.

Do note that this tutorial is compatible only for the LG G3 – for all the models of the G3 since below you will find stock firmwares for various LG G3 variants. Anyway, don’t apply this unroot method in case you own a similar or different Android device.
