Features:
- Flash the Harman/Kardon function of the Harman/Kardon Sprint M8 to stock GSM, VZW, and Sprint phones
- Flash the BoomSound function back to all phones, make the Sprint H/K Phone a BoomSound phone (theoretically working, untested).
- Flash the JBL Audio function of the Butterfly 2 to stock GSM and Sprint phones (much like H/K, mostly a cosmetic difference)
- Each function being selectable in a neat Aroma UI, flashable via recovery.
