[AT&T Samsung Galaxy S II Skyrocket SGH-I727] wantowan2:
I went ahead and made the changes in your post above. Seeing as I had already synced the cm stuff and whatever make file wants to create a local_manifest and repo sync to find SlimRoms/device_samsung_skyrocket jb-4.2, I made a local_manifest that had just jb in it.

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="SlimRoms/device_samsung_skyrocket" path="device/samsung/skyrocket" remote="github" revision="jb" />
</manifest>

Hoping that would do.

SlimBean always just had a platform_manifest folder instread of a local_manifest file in .repo.

Just to confirm, the repo should consist of :

-SlimRoms/device_samsung_skyrocket -jb

-everything else that the local_manifest of cm-10.1 has.

Here comes the dumb question:

Should I make a local_manifest that looks like this

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="SlimRoms/device_samsung_skyrocket" path="device/samsung/skyrocket" remote="github" revision="jb" />
<project name="CyanogenMod/android_device_samsung_hercules" path="device/samsung/hercules" remote="github" revision="cm-10.1" />
<project name="CyanogenMod/android_device_samsung_msm8660-common" path="device/samsung/msm8660-common" remote="github" revision="cm-10.1" />
<project name="CyanogenMod/android_device_samsung_qcom-common" path="device/samsung/qcom-common" remote="github" revision="cm-10.1" />
<project name="CyanogenMod/android_kernel_samsung_msm8660-common" path="kernel/samsung/msm8660-common" remote="github" revision="cm-10.1" />
<project name="TheMuppets/proprietary_vendor_samsung" path="vendor/samsung" remote="github" revision="cm-10.1" />
<project name="CyanogenMod/android_device_samsung_celox-common" path="device/samsung/celox-common" remote="github" />
</manifest>

to pre-empt the manifest?

Because I get this:

Edit:

When I lunch it I get this now?
