MultiROM was developed some time ago, and with it came the spectacular ability to be able to boot into different ROM’s seamlessly. Before if you wanted to wanted to try or use another ROM, you would have to backup and wipe your current configuration and then reflash it when you wanted to use it again. For a normal user, that may not seem like such a hassle if you found yourself only doing so sparingly. For flash junkies though, that could easily become a nuisance. If you are currently using a Nexus 6, you too can now use MultiROM to sate your need to flash.
The tool added support for the Nexus 6 today, and can be downloaded using the link provided below. While the tool appears to be stable enough to use for general usage, you should still remember that there is always a risk associated when making modifications to your smartphone. With that said, if you should head over to XDA to get more information and download the tool if you have a Nexus 6 and you want to add some new life to your device.
