I am very much new at most everything root and custom ROM. That said thanks to many of you on this board and the wonders of YouTube , I feel I am able to get by with my meager knowledge of ROM's. What I can't seem to grasp is how/why/when to update or change kernels. How do you know your build can accept different kernels? Why do you change the kernel that was part of the build? When do you know it is time to try different kernels?
