So I used root explorer to replace the build.prop in the system directory with the one from that custom ROM linked to above...shouldn't that have done it? I am still getting the update message.
Note II N7100 - love it so far, amazing battery life - died of SDS
Nexus 4 - couldn't get over poor battery
Galaxy Nexus - loved it
Nexus S - tried for a month, meh
Nexus One - loved it
