This will be a tutorial for people who want to Triple Boot on their Nexus 4. I will not explain how to unlock/root or install a newer or older version of TWRP.
The tutorial is based on having an Android ROM as a base. I will be using the PSX rom as main.
Step 3: Installing FirefoxOS
Download the following files:
System (Build September 30)
User Interface (Build October 5) FirefoxOS 1.3
Install the Mako_FFOS-20130930_system.zip as new ROM in the MultiROM interface. When it is installed go to List ROMs.
Then Flash ZIP the Mako_FFOS-20131005_UI_1.3.zip User Interface.
When you reboot your Nexus 4 you will be able to boot into FirefoxOS
Step 4: Installing Ubuntu Touch
For Ubuntu Touch to boot you need at least the 9-10-2013 built. This can be found on the Ubuntu website: http://cdimage.ubuntu.com/ubuntu-tou...-preinstalled/
You will need the saucy-preinstalled-touch-armhf.zip as a base.
And saucy-preinstalled-touch-armel+mako.zip as the second thing to install.
In MultiROM there is a seperate menu for adding Ubuntu Touch to the MultiROM list. This will take a while.
You will now be able to boot Ubuntu Touch when rebooting the device. Please know that the latest nighly's take a very long time to boot. At least 1,5 minutes.
Here is a Youtube video of it all. I also included a second Android ROM with a different kernel. The Main android ROM has the Franco Kernel and the second one has the NEO kernel.
