As you might already know, on most Android UI systems gaining root is possible only if an unlocked bootloader is ensured. Well, that aspect is also being applied when discussing about the new LG G7 ThinQ and since the OEM is already offering unlocking codes for certain models of the same device you can now successfully choose to root your phone. And that’s exactly what we will be checking during the following guidelines – rooting the LG G7 by using an intuitive and fast procedure.
Of course, before resuming the steps explained in this tutorial you have to unlock your LG G7 bootloader – and for now unlocking codes are available only for the European model of the latest LG flagship, meaning that this root solution is currently compatible only with this particular model of the G7.
As for the root operation you need to know that it will help you gain further control over the Android OS that runs on your device. Shortly, you will manage to remove factory or default restrictions that runs by default on your LG G7 and which are there to limit your access and your tweaking initiatives. That’s why, once you take care of the root process, applying custom operations will be possible and customizing, optimizing and personalizing the Android system will be at your disposal.
In that respect, here are a few examples of tweaks that can be applied on a rooted Android device: you can choose to remove bloatware, you can add root-only apps and tools that can be found on other sources than Google Play, you can install custom MODs and kernels, you can update with custom ROMs, you can overclock or undervolt CPU frequencies and so much more.
Unfortunately, LG cannot authorize such procedures and here we include the root process too. That’s why, the operation that’s detailed below is not supported by your OEM and cannot be associated with LG. Furthermore, as the immediate conclusion, if you choose to root your LG G7 you are going to lose your phone’s warranty. Do note that restoring the warranty is possible only if you choose to revoke root access and relock the bootloader which can be done by reinstalling the stock Android firmware on your handset.
A backup should be completed on your device before starting the root operation. The backup will help you secure your personal data, info, accounts and files which might get corrupted or wiped out while you apply the steps from this guide. On your phone you can save general stuffs easily by using different backup and restore solutions: use built-in cloud storage apps, use dedicated apps from Google Play or sync files with your Google Account. The goal is to save as much as possible, including essential files such as contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and so on.
Gaining root can be done only manually meaning that a computer will have to be used. On that computer your phone’s drivers must be installed and the Android SDK toolkit set up – you can learn how to install Android SDK on Windows by using this guide or how to set up ADB on MAC OS X / Linux by using this tutorial instead.
On your LG G7 you have to enable Developer Options by tapping repeatedly on Built Number – do that until the ‘you are a developer’ message is being returned. Next, on your phone you have to check the USB Debugging feature and the Unknown Sources field, which are located under Menu – > Settings – > Developer Options.
You also have to verify the power level that’s still left on your LG G7 as a charging might be required before the root operation is initiated – when the power is low your device can get switched off in the middle of the unlocking process, situation during which you can end up in experience different software related problems. So, if the power left is currently lower than 50% you should plug in the charger first.
Remember to unlock your LG G7 bootloader before doing anything else as otherwise the root process cannot be successfully completed.
