I have 13 old galaxy tablets running android 3.0 that i would like to run cyanogen on. All google links are dead. they are SCH-i800 and i wouldn't bother but something has happened to play store so that it's not loading on all but one of the tablets. It gives a weird redirect to a web browser page. Also i was considering using them as wall remotes for home automation but the app i want to use requires at least android 4.2.
From the source listed below, there were backups made at archive.com of snapshots and nightly builds of CyanogenMod. There are many models, but I am not sure about yours.
