    shell@android:/ # pm list packages | grep 
    package:com.android.providers.applications
    package:com.android.providers.calendar
    package:com.android.providers.contacts
    package:com.android.providers.downloads

    shell@android:/ # pm uninstall 
    shell@android:/ # exit
    shell@android:/ $ exit
    $

Basically, you log into android shell, become superuser, find problematic packages, and uninstall it
