Yes, but please use the updated version (see first post).
Make sure the stock camera-ui isn't running in the background:
(as root) dsmetook -k /usr/bin/camera-ui
remove camera-ui link
rm /usr/bin/camera-ui
rename camera-ui2
mv /usr/bin/camera-ui2 /usr/bin/camera-ui

Test if this works (start camera-ui with the camera-ui icon)
Test if your device get into a reboot loop. If so you did
something wrong. (search this thread on how to get out
of the reboot loop (use r&d-mode to disable watchdog))
