I tried all of them, except the busybox idea.
I got it to work though, what I did was clean flash back to stock.
Then I flashed DOOMLORDS kernel + TWRP (http://forum.xda-developers.com/show....php?t=2338693).
Then I booted into TWRP, factory reset, wiped devilik cache.
Then flashed the CARBON ROM, then the Gapps.
Works great. The als sensor works fine, it was a bit eratic at first but it seems to have come good now.
Don't have the WiFi problem.
I see the white screen, but I think that is a easy fix.
Don't have the time problem.
Don't have the gallery problem.
I do have the camera problem. I even had a time the phone locked up and had to do a hard reset.
