Multiboot, or the ability to select between multiple operating systems on a single device at boot, is an inherently interesting concept. Not only does this allow users to try out new ROMs without losing their data, but it also allows users to keep a particular ROM for one purpose while using other ROMs or even operating systems for something entirely different. We’ve recently covered quite a few multiboot solutions for various devices in the past few weeks, and now we have one more to add to the list, the Samsung Galaxy S 4 i9505.
This work comes courtesy of XDA Senior Member AntaresOne, who is continuing previous work by Senior Member oblikas. For those not familiar with oblikas’s work, he unofficially ported Tasssadar’s MultiROM project over to the S4 back in October of last year, but work on the project has since ended. Now, AntaresOne has picked up where oblikas left off and updated this MultiROM port to work with the latest ROMs for both Android and the partially functional Ubuntu Touch builds available for the device. Furthermore, AntaresOne states that he will continue updating the project when alternative OSes such as Firefox OS and Sailfish OS make their way over to the device, however they will likely work as is because of their similarity to the MultiROM system.
If you’ve been looking to add MultiROM support to your S4, head over to the MultiROM for the Galaxy S4 thread and get started. Just be sure to have a good backup before proceeding!
