If you are on an officially supported device (in an unsupported country)...
Before installing Home you need to ensure that both latest Facebook main app (katana) and Messenger app (orca) are installed... once they are, use this link - DOWNLOAD (ROMraid) - to install Facebook Home then activate Facebook Home in the Facebook application's 'Settings' menu.
On an unsupported device? No option to activate Facebook Home?
Don't worry, I have you covered! I've patched the Facebook application to remove the device check. You need to uninstall your existing Facebook, Messenger and Home applications (necessary because the patched versions are re-signed), then install the patched Facebook main app (katana) - DOWNLOAD (ROMraid), the patched Messenger app (orca) - DOWNLOAD (ROMraid) and the patched Home app - DOWNLOAD (ROMraid). Sign in and in the Facebook application's 'Settings' menu the Facebook Home option should appear for you!
On an unsupported device? Rooted and want to use the unpatched versions?
The latest version of the MoDaCo Toolkit includes a module to make your device appear compatible to the unpatched Facebook app. Details are in this topic.
Let me know how you get on. One last thing - if you want to post about this elsewhere, PLEASE link back to this post, don't deep link the files or pinch them for yourself. Thanks.
