    Hi team,

    I always have gotten great help here - and for all the talk of wiping dalvik and other caches, I haven't found a straight forward guide for now to prepare my phone for installation of a new kernel.

    I've been on skyraider awhile, and put King BFS 4 on. I'd like to go to the new BFS 5 and see if it improves the battery life.

    Can someone point me toward a simple guide of how to prepare the phone for a new kernel? I know how to install it. What caches need to be wiped? Can it be done through clockwork? I've already done the nandroid backup.

    Thanks!

    Thanks for the advice - but I guess I'm asking more 'how do you wipe the dalvik cache?' Is this done through clockwork? Just prior to flashing the new one? Anything else to wipe? and if so, how?

    yes you can do this from clockwork, its under advanced i think. titanium backup also allows you to wipe it

    Not to high-jack this thread or anything but I was about to post something similar. I already installed my first kernel and didn't wipe dalvik. is it to late or can i wipe it now?


    also what about the battery stats? are we supposed to wipe them also?


    P.S. what happens when you don't wipe the dalvik? I'm using the hydra kernel under-volt and haven't noticed any better batt life. I'm actually experiencing worse life(but it's only day 2)

    If you didn't wipe dalvik oh boy :p JK

    If it runs fine I wouldn't worry about it this time around. I would start doing it from now on though. I think it's a safety measure.

    As for battery stats it doesn't hurt and probably a good idea with a new kernel. It's under advanced in CMR as well as dalvik cache. Just make sure your battery is fully charged with a bump before you wipe battery stats. That's what I do, but there are 2 schools of thought on this one. gl!

    Basically, if the phone boots it's working. If you're using an over/under clock kernel, you can tell what it's doing at any given moment by opening SetCPU or a similar app that displays the current MHZ.

    Did you're phone boot? Then the kernel is working.

    Wherever you are downloading the kernel from usually has a description of the features of the kernel.
