When LG first released the LG G7 ThinQ the company mentioned that it won’t support the unlocking bootloader process. However, that plans were reconsidered and now, listed on the ‘unlock bootloader’ official LG page we have the European model of the LG G7 – version number LMG710EM. Thus, as always, we are here to back you up in term of tweaking initiatives meaning that during the following guidelines we will be checking on how to easily and safely unlock the LG G7 bootloader, a process that can be completed with the LG support.
Of course, unlocking the bootloader is a process only half official – LG is providing the unlock code but the actual operation is still unofficial. Shortly, unfortunately, after applying the steps explained below the LG warranty won’t cover your European LG G7 anymore. The warranty can be restored or regained only if you choose to relock the bootloader which can be done by reinstalling the stock / official Android firmware on your device – of course, in that situation you will also manage to revoke any other tweaks that were previously applied (such as root for example).
The bootloader is a small program, a script that runs on your LG G7 like on any other Android based device. This program will be initiated and will run each time a boot or a reboot sequence will be applied. In those cases the bootloader will load the Android OS and other essential start-up programs and features from the ROM memory into the RAM section – so, without this program your smartphone cannot run properly. The thing is that by default the bootloader is loaded with various restrictions which will limit your further access towards the Android core system.
So, if you are an advanced Android user who is thinking in applying custom operations on his LG G7, you will first have to remove the factory restrictions by unlocking the bootloader. Afterwards, you can successfully tweak your handset by initiating various operations including the following ones: you can install TWRP recovery or any other custom recovery image, you can add a custom kernel or MOD, you can gain root access by flashing root exploits, you can update with custom ROMs such as Lineage OS, AOKP or Paranoid Android, you can make Nandroid backups, you can remove bloatware, you can install apps from other sources than Google Play, you can overclock your Android device and lot more.
You should backup your LG G7 before starting to apply the steps explained below. In this way you can be sure that everything that’s important for you will remain safe and secured during the unlocking process. So, choose to save your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data and anything else that might mean something for you. A general backup can be applied in different ways: you can choose to use built-in cloud storage apps or platforms, you can sync certain files with your Google Account or you can go to Google Play and download dedicated backup and restore tools.
A computer is required as everything will happen from there. On this computer the LG G7 drivers must be set up; also, Android SDK must be installed: learn how to install Android SDK on Windows or learn how to set up ADB on MAC OS X / Linux.
On your smartphone you have to become a developer. This operation can be completed by tapping repeatedly on Built Number (within Menu – > Settings – > About Phone) – after 7 or 10 taps you will receive the ‘you are a developer’ message. Afterwards, from Settings you will be able to access the Developer Options field; well, from there you now have to select the USB Debugging option and the OEM Unlocking feature.
It’s more than recommended to verify how much power is there left on your LG G7. As a general rule, before starting to unlock your phone’s bootloader you should ensure a minimum of 50% power – otherwise, your handset can get turned off during the operation that’s explained in this tutorial and then you can end up in experiencing different malfunctions: you can end up in soft-bricking your phone. Therefore, plug in the charger if the power left is currently lower than 50%.
Of course, follow this step by step guide only if you own the European model of the LG G7 with version number LMG710EM.
