Hi! I'm looking for some resources that explain how the Android hardware and OS works as a whole. Most of the posts I see on here have to do with specific areas. My goal is have a better understanding about: 1. HBOOT - Different versions, How it works, how to update it, etc. 2. Recovery - Different versions, How it works, how to update it, etc. 3. System Partitions - System, Cache, SD-EXT, etc. - What each partition contains 4. Kernels - Different versions, how to load/replace 5. Radios I looked for an "Android for Dummies" book and notice there's one for app dev coming out in December -- which I'll probably get. But I'd like to know more about the OS itself first. Any suggestions?
