My ePad gets the message "demo version has expired" in the center of the screen no matter what I do. Look at the video to see what I mean. I tried the firmware Slatedroid1.3-flytouch-edition V2, but it doesn't fix it. I also tried reverting to the stock 1.7.4 firmware to no avail. 1.8.2 also doesn't fix it. System reset also doesn't work. Help!
