Installing multiple ROMs at the same time and choosing which one to boot can be easier than you think. To install many ROMs on your phone you simply need to install MultiROM, which is one of the best mods for Android devices.
Android is a versatile OS and there are endless possibilities when it comes to customizing and modding. You can do many things with an Android phone. You can install custom ROMs, kernels, and mods to improve and make your phone better.
Along these, you can also install a mod called MultiROM. It allows you to install more than one ROM on your phone. So you have you current ROM (primary) and a second and third ROM (secondary). When you install more than one, you have the option to choose which one to boot when the phone reboots.
This mod has been available on some of the most important devices and now it has landed to the Sony Xperia ZL.
The Xperia ZL is Xperia Z’s sibling with simular hardware and design. While it hasn’t received the attention that the Xperia Z’ did, it has managed to enjoy some of the most popular mods like MultiROM.
With MultiROM on the Sony Xperia ZL, you don’t only have the option to install multiple ROMs at the same time but also install other operating systems like Ubuntu Touch. You can boot a ROM using a USB OTG cable. If you have a Nandroid backup, you can restore it as a secondary ROM. You can even install CyanogenMod 12 Android 5.0 Lollipop ROMs so you get to enjoy 4.4 KitKat and Lollipop at the same time.
