There is no larger craze in the world of customizing mobile devices than custom ROMs. A custom ROM is going to replace the software that you see on the screen now (the Android software provided by Android developers themselves mixed with carriers and manufacturers) and replace it with a new version of software made by third-party developers. Even though a custom ROM is not technically a new operating system, it looks like it is. The amount of differences that you get depends on the custom ROM that you choose to install, but the differences can be anything from gigantic to custom ROMs that intentionally stick close to what Android created. It all depends on your reasons for wanting to install a custom ROM.
A custom ROM installed on the LG G2 smartphone is useful for people who want to see new designs, use new user interfaces that come with new layouts, use new features instead of the limited features Android offers to millions around the world, having a ROM with the system apps removed (often referred to as debloated), and other reasons like using truly open source software.
So now that you know what a custom ROM is and why people want to install them, it’s time to look into what is required for installing a new ROM on a device. Most people think that installing a custom ROM is somehow relevant to rooting Android operating systems when in fact about the only thing it has in common is the fact that they both customize the device in some way. Rooting Android is not usually connected with or required before installing a custom ROM. A custom ROM is replacing the Android software whereas rooting is giving the existing Android more permissions for you to use. What really matters before installing a custom ROM is unlocking the bootloader and then installing the custom recovery. Make sure you always unlock the bootloader and not just if you need it unlocked to install a custom recovery. Most custom ROMs requires the bootloader be unlocked before you install them or else they cannot load. A custom recovery offers you the chance to get the new custom ROMs installed. The recovery environment that already comes on your device is now known as the stock recovery does not have the feature to install files.
Details We Should Know
You need to unlock the bootloader before installing a custom ROM on the LG G2 smartphone before the custom ROM can be installed.
You need to install a custom recovery image on the LG G2 smartphone before a custom ROM file can be installed. It doesn’t usually matter what custom recovery you choose to install because all of them tend to come with the necessary features that are required for installing the ROMs; however, if you want a recommendation we always suggest installing the TWRP Recovery. It is the most popular custom recovery today and will likely be for some time to come. That said, there is nothing wrong with installing something like ClockworkMod Recovery and using it—we sometimes do too! There may be times, however, when a certain ROM has a requirement of a particular custom recovery such as TWRP or CyanogenMod. Check the details from the downloads links.
