We’ve talked about MultiROM a few times already here. Anyone who fancies running versions of Android KitKat, Ice Cream Sandwich, and Jelly Bean all from the same device can now see that dream come true. Sony Xperia devices are the latest ones to enjoy MultiROM multi-boot goodness with the new MultiROM v30x mod.
The MultiROM v30x appears to support a number of Sony Xperia devices including the Xperia Z1, Xperia Z1 Compact, Xperia Z2, and the Xperia ZL models. So if you’ve thought about running multiple ROMs on your Xperia device — heck even an Ubuntu Touch firmware or any other Linux-based system — now is your time to shine. A built-in boot manager appears upon startup and gives you the power to choose which systems to run for your device at a particular time. Installing and managing ROMs is done through the built-in MultiROM manager app.
Probably the only thing that would limit your device from enjoying the multiboot advantages of MultiROM is your device’s storage limit. You can have as many ROMs as you can possibly fit into your smartphone’s external memory card. Another limitation is that MultiROM, at present, will not work with data encryption, but that shouldn’t be a significant concern to you unless you’re absolutely serious about your device’s data security.
There is always a concern when tweaking your phone like this, understand that most smartphones were created without any notion of multi-booting, and tweaking them this way can easily turn into one big epic fail. Like any custom hack — and this is a major one — it is always a good idea to back up data in your device so that you don’t end up with a particularly expensive block of worthless electronics.
