I know that if your phone can't run a certain kernel it'll freeze or boot, etc. What I want to know is what you do when this happens. Do you just upload a different kernel via update.zip in recovery, or how would you fix it. I am currently running p3 1ghz 125mhz and would like to try higher kernels but would like to know before hand when I run into that scenario. Oh and does the existing kernel need to be removed beforehand, if so, how.
