If you have in mind the idea of tweaking your new LG G4, then it’s obviously that you must learn some basic operations and custom procedures that will bring the changes that you want. However, you’ll discover that many of them will require fastboot mode. What is fastboot mode? How can you boot into Fastboot Mode on LG G4? Do not hesitate and continue reading; also use this tutorial for learning more about what this procedure is and what it involves.

Fastboot mode is nothing else than a hidden menu featured by default on today’s Android devices, just as Samsung has its special Download mode which it is practically doing the very same thing, even though it has a different name). Fastboot gives you the possibility to re-flash partitions on your LG G4.

It works through PC command line and connects over a USB connection with your G4; then, by accessing this hidden menu you will be able to enter recovery mode for completing various procedures, to reboot the bootloader, to replace a custom ROM, to use a custom kernel for overclocking your smartphone, to remove bloatware, to prepare the device for manual updates and not only.

Before starting, I advice you though to back up your data. In many procedures, the data is being wiped out, so take no chances or you might end up regretting. And another important aspect is to plug in the charger on your phone if the battery status of your device is showing less than 60% power left.

And even if the process is official since the fastboot environment is featured by default on your LG G4 (so the warranty is perfectly safe), you still have to be careful about every single step that you are taking.
