what i did, in order, without kernel

1st, i made 2 dirs in ~/, jb for aosp and cm10 for cm
then, i followed http://forum.xda-developers.com/showpost.php?p=28626754&postcount=1 to try to build aosp in ~/jb.

then


cd ~/cm10
repo init -u https://github.com/CyanogenMod/android.git -b jellybean
repo sync -j16
cp -r ~/cm9/device/samsung/skyrocket ~/cm10/device/samsung/
cp -r ~/cm9/device/samsung/msm8660-common/ ~/cm10/device/samsung/

edit /build/envsetup.sh and device/samsung/skyrocket/envsetup.sh and add "add_lunch_combo cm_skyrocket-userdebug"

create local_manifest.xml with device/samsung/skyrocket and device/samsung/msm8660-common
repo sync -j16

cd ~/cm10
. build/envsetup.sh
./vendor/cm/get-prebuilts
brunch cm_skyrocket-userdebug
