So I have an old unlocked phone and I'd like to load up my own OS. I've seen some mods out there. CyanogenMod seems to be the most popular. However, I was curious if I could just install a pure untouched version of the OS -- as distributed by Google. I seem to remember being able to download a clean compiled version of the Android OS.
Does Google distribute any binaries like this, and if not, is there someone out there that does?
Additionally, is this even worth trying? These days is it necessary for Android to be packaged with special drivers and such for all of the different hardware out there?
