So I want to try out a new Kernel but I've never flashed one before. According to this Kernel's page on XDA i can Boot it through fastboot without flashing it - and i can therefore test it and revert to the current image on reboot. But i can't figure out how to do this -> any ideas? Secondly do i need to a do clean install and wipe everything before flashing the new Kernel, or is it ok to just flash it? I suppose if it does go wrong i can revert to a stock image anyway so there is nothing to loose in flashing and trying without wiping?
