So I modded FB Home to run on all (?) devices, without touching build.prop or requiring root.
Tested on GNEX, NEXUS 7 emulators.

Installation
• Uninstall original facebook, facebook messenger and facebook home apps. If facebook is pre-installed then you probably need root to remove it
• Extract .rar!
• Install com.facebook.katana (FB app), then com.facebook.home (Home app).
• Also install com.facebook.orca.apk (Messenger app).
• Enable facebook home under facebook app settings.
• If you face any issues, reboot into recovery and wipe dalvik cache.
Expecting your feedback.
