Do a factory reset.
1. With a paper clip (or similar) depress the reset pin located at the bottom of the OBi.
2. While keeping the reset pin depressed, plug-in the power cord.
First, the Power LED will turn red, then become sold green.
Keep depressing the reset pin while this is occurring.
3. After 10 seconds, the Power LED will start to flash green (slowly).
You may now release the reset pin.
4. Within 5 seconds, the Power led will start to flash green rapidly for about 3 seconds.
5. Next the Power LED will change to red briefly indicating the OBi is now rebooting.
The factory reset is now complete.
