lg g2 stock

The users of Android are entitled to a sense of adventure and freedom that comes after rooting the device and installing a custom recovery on it. If you have root access on your Android device, you can install apps that require root permission and thus tweak your device, customize it, get better battery life, remove bloat apps and so on. By installing a custom recovery, you can try a custom ROM and enjoy enhanced features on your device.

Having root access on an Android device and experimenting with root apps, custom mods and ROMs is really a pleasant thing. However, it’s also true that sometimes things might not turn up as expected and you might end up with a device that refuses to boot up. In such situations, restoring the stock firmware back might appear to be the only way to recover your phone. Installing the official firmware back might also prove to your last haven if you wish to unroot your phone and remove the CWM/TWRP recovery.
