I recently bought an iRex DR800 - with no accessories included. This wasn't an issue for me, until I tried to upgrade the device to a newer firmware. The update completed just fine until it came time to start it up again. Now it's wanting to go through "stylus calibration", but since I don't have a stylus for this device, I can't complete it and so I am completely unable to use the device. So I was hoping that there might be some miracle solution to bypassing the stylus calibration? If not, I would be willing to purchase a compatible stylus for the iRex - something which I am hesitant to do by myself as I do not want to accidentally purchase an incompatible stylus. Any help would be appreciated.
