Installation was fairly easy.

The main issues/things that don't work expect that I've noticed are:

• WiFi issues (networks showed at first but later do not show up at all)
• Mobile Data issues (txt works OK, device has ip from carrier but connection still does not work)
  • I am in the US with TMobile
  • Unlike @drym4rch0n , my device does recognize the sim in slot one as TMobile
  • Looks like it would work with some tweaks (although I'm not sure what those are yet)
• Sound in calls does not work
• Bluetooth Audio does not work (although discovery and pairing seemed to work ok)
• Touch buttons do not do anything currently
• Slider does not do anything

Overall, I am impressed with how much does work!
Where can I find the source and instructions for trying to build myself? I might be interested in trying to hunt down some bugs.
