Yeah, I see a bit of a smoking gun there, but it's not being used.
Code:
.field public static final blacklist INJECTOR_DEVICE_ID:I = 0x77654321
They stick a lot of UI stuff in KCB. I don't see anything in my KCB. Can you get me a copy. It might not be named exactly the same, but it will be an .apk
Code:
C:\>adb pull /system/priv-app/kcb-release/kcb-release.apk
