I can't get this to work on my N910C. Have tried both procedures, both failed. After reboot of device a camera fc message is shown. I do see the new camera icon, as described in startpost. But the camera won't start up.
I'm on Wanam's custom rom v1.5 and Adam (Wanam) custom kernel.
First I tried the first procedure by installing zip in recovery. Then (after a restore of previous backup) I tried the 2nd procedure: removed both apk and odex files, using ES File Explorer. Copied new camera apk and xml files to proper locations and set the correct permissions.
In both cases the new icon is in app drawer but the camera won't start up.
Strange or am I missing something?
