Thanks! Just what I needed to factory reset the device. I have a case # with Samsung because I cannot load any apps to my external SD card. However, when I go into Odin mode and connect, the device is not recognized. I get the message in a pop-up window: Please connect phones.
In device manager it is listed as MSM7x30 with a driver that is not recognized. Everything works as it should when not in Odin mode, e.g. I can type adb commands at the command line and get the proper responses. I reloaded the Samsung drivers and all four devices were loaded correctly according to the message.
