So I take it there is no custom stock Android ROM available for the Fire phone? I only found a fake Android L ROM. You can root it, though, a fairly recent development apparently.
I didn't need to root it to get the Google Play Store side loaded, so I haven't looked into that, either. That said, if I can't figure out how to replace the awful launcher/home screen on this thing, I may eventually give it over the to CM gods (or whatever custom ROM comes along). I would like my back button, as well.
Edit: this conversation led to me googling how to replace the annoying launcher...it was as easy as installing Google Now Launcher. I just reduced my dislike of my phone by another large measure. Now, if I can just get the back button to come back, the stupid tilt functions disabled, and google maps to work right, this might turn out to be a decent phone.
