I downloaded kino2, mplayer, sudo and batteryapplet as per the instructions on Maslovsky's page to install on my C860 Sharp ROM. I installed sudo and then the battery applet and the Zaurus rebooted by itself and kept rebooting. It would go to the screen that has CG graphics, Zaurus and something in Japanese starting with 1, which I guess says please wait one minute. Then it would quickly flash a boot message too quick to read, go back to that screen and be like that. Removing and replacing the battery would bring the same again. I fixed it by going to the boot menu (hold OK on power up) and selecting the third option (erase all) which brought the Z back to factory condition (japanese and all), from where I could restore from backup (phew!).
Now I am afraid of installing kino2 again. Anything I did wrong? Any step I should avoid?
