I picked this up on ebay I got it to work (easy part) but the screen is locked. I powered it up while holding the back button. Once it showed the android logo I let go of the power button and it went into a recovery (rest mode)? I think I needed the sd card installed and loaded with something so it would reboot and unlock/remove the passcode. I guess this is a start over and a good way to unlock a locked tablet. I don`t know the software end of these but I think I am getting close on this one. I think that all of the cobys will do this. Let me know if I am wrong. Thanks for any replies.
