Tweaking your LG G2 is easy but unfortunately it is not always safe. If for example you are using guides that haven’t been previously tested you can end up in messing things up and also in damaging or bricking your Android smartphone. So, then you will find yourself in a delicate situation as you will have to unbrick the LG G2 by yourself – you can’t take your phone to service since you have applied an unofficial procedure as the warranty has been void. Because of that I have decided to develop this dedicated tutorial which can easily teach you how to fix a damaged or bricked LG G2.

Now, during the guidelines from below you can find several ways that can be used for repairing your Android device. So read all the lines and see which procedure to apply in your case.

Do note that in case your device is severe damaged and you cannot apply the steps from below for unbrick it, the only solution you can take is the one where you go with your LG G2 back to service for technical assistance – but let’s hope you don’t have to do so.

You can say you have a bricked LG G2 when your phone can’t be used in normal way. For example you notice that you device runs with lags, there are numerous bugs, the screen and the apps freezes constantly, the battery drain fast, your phone gets stuck in a boot loop, it always boot in recovery mode and so on. These problems might happen due to various reasons but in most of cases the users are experiencing issues after performing operations like gaining root access, unlocking the bootloader, updating with a custom ROM firmware, installing a custom recovery image, flashing a custom kernel, overclocking the device, removing bloatware or in built programs and so on.

All the mentioned procedures are unofficial ones and when performing the same the warranty of your LG G2 gets void – because the binary flash counter will be increased. Now, if you end up in damaging or bricking your Android smartphone, you shouldn’t panic as you can use different methods that can repair your device. The best methods are being explained during the guidelines from below, so you are in the right place.

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.

    My AT&T G2 appears to be in a neverending bootloop. I cannot turn it off, I cannot perform a hard reset, and I cannot enter download mode. No matter what button combo I use, I get a secure booting error – LG logo + about 5 seconds of tiny white text at the top of the screen, followed by the screen going dark (but not shutting off). Any ideas?
