By the way? i looked at the my kobo touch and the original kobo and I dont see any reset button on either device, it would help if i could find it lol.
There is a small hole in the back of the Kobos that can be used to reset them. To reset a Kobo ereader unfold a paper clip and slid one end gently into the hole until you hear a click. This type of reset will reboot the ereader and will fix some situations where a Kobo is unresponsive.
