While Nexus 5 and Nexus 7 (2013) owners have been enjoying the Android L Developer Preview for a couple of weeks, owners of other Nexus devices have been wondering when they will get in on the action. Well if you own a Nexus 4 (mako) or a Nexus 7 2012 (grouper), you can thanks to ported ROMs.
XDA members sykopompos, defconoi, ben1066, and percy_g2 put together a pretty solid ROM for the Nexus 4. I can't tell who created it since it's not loading on the XDA site, but a few important things are non-functioning, like Bluetooth.
If you want to try out either ROM, hit the appropriate source link below.
