Flashing kernals is new to me although general rooting is not. Apparently with my new Inc I have the slcd which will only work with a few kernals. What I had to do to get some new ROMs working was flash the ROM, then flash a specific kernal before booting up. That worked and I was able to flash some ROMs that I was not previously able to use. It has come to my attention that there are some kernals out there that are better for battery life so my questions are: 1) If I want to flash a new kernal over my existing ROM can I just do that? Boot into recovery and flash the new kernal? (After a nandroid of course.) Or do I have to flash the ROM again, then flash the new kernal and then boot up? Do I need to wipe anything before flashing a new kernal? 2) What are the best kernals for battery life that work with the slcd screen? Thanks in advance for any help.
