It seems like XDA Recognized Developer Tassadar‘s MultiROM seems to be quite the popular method for different devices to boot multiple ROMs nowadays, considering that MultiROM was originally developed for only the Nexus 7 and has since been ported over to a number of other phones such as the Sony Xperia M and the Optimus One. And the community doesn’t look like stopping any time soon, as the HTC Droid DNA, a.k.a. HTC Butterfly, has recently received an unofficial MultiROM port.
This comes thanks to the efforts of XDA Senior Member jamiethemorris, making it possible for users of the Droid DNA to run multiple ROMs (not at the same time of course) without the hassle other devices must go through. The installation process comes in three parts:
- flashing the provided MultiROM zip through a custom recovery
- flash the provided modified recovery through fastboot or with Flashify
- install a kernel with the kexec-hardboot patch (currently only supports two kernels with more to be added in the future)
Installation will not wipe or affect the sole, primary ROM you’re using right now. Additionally, you can run ROMs installed on a USB drive, which has to be connected to the phone with an OTG cable. To boot another ROM, you simply choose from those installed on your device or a USB drive from a menu at startup, and you’re good to go.
So if you’re interested in booting multiple roms on your Droid DNA, or would like to find out more, check out the original thread for more information.
