I am getting my Rezound in the mail either today or tomorrow (hopefully today) and I needed a few questions answered. I plan on unlocking the bootloader and rooting my phone. However, after this, I don't know how to proceed. With the my past Droid, I just rooted the phone and put on CM7 by using ROMManager. But this Rezound stuff seems way more complicated. What is a Kernel? How does it differ from a ROM? What is flashing a recovery? Why do you need to flash recoveries sometimes to flash custom ROMS? Also, what is S-Off or S-On (does it mean you turned Sense off?)? Any help would be appreciated. I really want to root my phone and unlock the bootloader, and I know I am knowledgeable enough to do it. I just want to know what I am doing in terms of background information. So if anyone could give me like a general overview on what does what, I would appreciate it. I know I can follow the guide and I'll have the stuff done in no time, but I'd rather have the background information in case I somehow mess up or get confused about things.
