Is it possible to boot Amazon Fire Phone with a vanilla build of Android Lollipop? I was wondering if it would be possible to run a vanilla Android Lollipop build on Amazon Fire phone. Google won't support it by default, but is there a patched version of the Lollipop ROM that could be used to run Android on it?
For everyone who has dreamed about Android on the Fire phone: It is possible. You can install CM11 (Android KitKat 4.4.X) on your device. The procedure is described here on XDA: [ROM][STABLE] CM-11 for Safestrap v4 2015/08/10

There are some issues and bugs, but if you are interested in it, then go for it ;)

Fresh Installation


From Safestrap(the recovery you have to install), go into Wipe Menu and Swipe to perform a factory
reset.
Flash the ROM File
Flash PA Gapps Modular PICO
Flash the latest SuperSU package if you want root
Reboot
Enjoy!
