And here is AOSP-4.2.2, with fully working camera, GPS, bluetooth (except receiving files, I think), audio, video, EGL, USB-OTG, WiFi, and sdcard. aosp-4.2.2-20150411-full_kai-ota-eng.pj.zip (md5sum: 2704cd29119265994d0a149a40866522 ) Watch out, when you install, that you follow cwm's advice to disable recovery flash, or your cwm will be overwritten with stock recovery. If you want, you can add the Google apps that go with Android-4.2.2 (dated 20130812), which you can also flash from cwm recovery. This was built using Cyanogenmod's framework/av and framework/native to make the camera HAL load. There's one last thing I'd like to try to do, and that is to identify those patches that make the camera HAL load, and go to aosp framework/av and framework/native. Suggestions, as always, are more than welcome!
