ABOUT

So what's this kernel? This kernel is how I envision

a kernel should be. It always has the latest from Google

and from Linux. but I also try to avoid ports because

they always seem to bring down performance sooner or later. So my goal

for this kernel is simple, keep it up to date and have fun,

it may not have all the cool stuff from other devs but you can

always count on that fun stuff happens. I believe that we all

should have fun tweaking our N9 and to change the others that

think our N9 is bad because it's not! Embrace the spirit of XDA and tweak on!

Here I stand!

Having said that... This kernel will never be said to be stable. In its

very nature its experimental, sure there may be a stable version here and there,

but there's no telling what the next version will bring. That's not saying

that i dont try to make it stable, it's because if it works for me does

not mean it will for you, and all my time being here from NOV 5 2014

has taught me that's very much so. If you want something that's

guaranteed to be stable try another kernel.
