So no worries since you don't flash all (you use the "Method2" from the link I posted above), about the "flash-all.sh" file, when you open the factory image file, you have this script, more info here about the "-w" to delete: http://forum.xda-developers.com/show...77&postcount=4.
thanks for you help my brother. Just another question.. If I have a nandroidbackup on the computer that I made before I installed my custom kernel, could you somehow use that to get back to the stock kernel? Is that something...or I am just asking the most ridiculous questions?
It seems the more I read, the less I am confident with adb, flashing, backups etc.... :S
