I just built and flashed a hybris-12.1 (cm-12.1) based hammerhead 2.0.1.7 build. This is the first build, so broken stuff is to be expected (and apparent). I grabbed cm-12.1 device and kernel repos, then rebased the mer-hybris specific commits on top.

What works:
- Radio appears to work, can't thoroughly test since this isn't my main device.
- Sound, touchscreen, screen, WiFi all are working.
- Bluetooth
- Camera now works in second build ...Camcorder is iffy (nothing new there).

What doesn't:
- No sensors (so nothing in messwerk).
- Store won't install apps (to be expected).


Edit: Updated above.
Edit2: apparently bluetooth works.
Edit3: I've played music over bluetooth for a few minutes now, something that would have been impossible on the cm-11.0 based build. Should be interesting to see if a pebble works now .

Edit4: The new build I'm doing has more default apps, and I'm working toward fixing camera based on lines 126+ of http://piratepad.net/hadk-faq

Edit5: Second build, fixed camera. Only thing I can verify as not working are sensors. Uploading/linking the build shortly.
