Before completing the steps from the proper guide, if possible save the data that is there on the internal storage memory of your LG G2. By applying the unbrick method all of your data will be erased, so you will lose your personal info, data and accounts along with contacts list, call logs, market apps, internet settings and so on. The best will be to use dedicated apps from Google Play, but as mentioned before only if you can use your smartphone; else you should skip this procedure as there is nothing you can do.

At the same time, you need to make sure that you can use a computer, your Android device and its USB cable. Now, on your computer it is recommended to deactivate the security protection as the antivirus or antimalware tools might interfere with our work. Moreover, you should charge your phone before doing anything else – plug in the charger especially if there is less than 50% power left, else you can skip this step. Also, remember that the procedures from below are compatible only with the LG G2 and with no other Android device. Furthermore, the steps have been tested only on the mentioned device, so the same will not work on any other smartphone or tablet.
