con una terminal adb: "setprop persist.sys.demomode disable" puede usar Root Browser y modificar la siguiente entrada "/data/property/persist.sys.demomode" de enable a disable. El video demo esta en /system/etc/demo/demo_video.mp4 si lo eliminas ya no saldra.

Via rooted terminal under su or adb shell: setprop persist.sys.demomode disable also you can use Root Browser and go to /data/property/persist.sys.demomode and with a text editor change the value from enable to disable. The demo video is located in /system/etc/demo/demo_video.mp4 you can delete it and it won't show again.
