Maru OS is not your ordinary feature packed highly customizable ROM, it is so much more. If anything, Mau OS is a clear testament to how far smartphones have come in just a few year. It hides a full-fledged desktop OS right inside your phone, and you won’t even notice it until you connect your phone to a PC. It is still the traditional Android, so you don’t have to learn new ways to operate your smartphone, but when you connect it to a PC, it transforms into a full Linux based desktop OS. It’s what Microsoft has been trying to achieve as well with Windows. If that sounds appealing to you, you can now install Maru OS on Nexus 5 and Nexus 7.

However, before proceeding any further, you should know that installing Maru will wipe up all your personal data, including your device’s internal storage. So it is better if you first backup all your data on your PC. Take a full Nandroid Backup of your ROM as well and store it on your PC. MaruOS for the Nexus 7 is still in beta mode so expect some bugs.

If you don’t know a lot about rooting and bootloaders, using the easy installers is a good idea. Your bootloader will automatically be unlocked during the process. But if you do know your way around Android, have an unlocked bootloader, you can easily flash the ROM from the recovery. Installing it via a custom recovery prevents the internal storage from being wiped, and you can also use Maru as a secondary ROM using MultiROM.

Disclaimer

Maru OS, like any other custom ROM, is an aftermarket firmware and installing it on your device will void any warranty that you may have. It is also a risky process, and there are chances, as small as they are, that you will end up with a bricked device even if you followed the guide. Hence DroidViews takes no responsibility for anything that you do to your device, you have been warned.
