One of the most popular methods of booting multiple ROMs on an Android device we’ve seen in the past few years is through MultiROM, a program originally developed by XDA Recognized Developer Tasssadar for the Nexus 7. With a number of unofficial ports to multiple other devices such as the Sony Xperia M and the HTC Droid DNA, it’s with no surprise that we see another device has followed suit.
This time, an unofficial port arrives to to the HTC One X courtesy of XDA Recognized Developer and Contributor Thunder07. This port allows owners of the One X to load multiple ROMs without with the need to backup, wipe, and restore previous ROMs. It also allows you to restore backups of individual ROMs you’ve made with TWRP without hassle.
Installation consists of flashing the provided ZIP files through a custom recovery, but before you do so, make sure you either set your device to S-Off or have an unlocked bootloader, and understand how KL Zeus works. Thunder07 provides some simple instructions for adding and removing ROMs, and switching kernels, as well as a simple ZIP package that you can flash if you want to remove MultiROM from your device.
So, if you’ve been waiting for a MultiROM port to come along to your HTC One X, be sure to head over to the original thread to get started.
