WHAT?!? Where did you buy this device, and when? That is an extremely old firmware build. Is this a brand new device from an authorized retailer like Amazon, Newegg, or B&H Photo, or did you get it from eBay or Craigslist, or did you find it at a bus station? Now, the title of your post becomes clearer. The current firmware is 3.2.2 (Build: 5898EX)
Try this.
Unplug the Ethernet and power cords. Plug back in just the power cord. Pick up the phone attached to the OBi and key in ***8 then 1 to confirm restoring to factory defaults, then hang up. Wait a good long time until it restores and reboots and the left-most (Power) LED is on steady, and the middle LED (Internet) is occasionally flickering.
Open your desktop/laptop web browser, and go here:
http://fw.obihai.com/OBi202-3-2-2-5859EX-198839.fwIt will download the firmware to your computer. Make note of the download directory.
Plug the Ethernet cable back into the device, unplug and then re-plug the power cord and let it fully boot up.
Pickup the phone again and key in ***1 and write down the IP address it reads to you.
Press Ctrl-T to open a new browser tab, and go to the IP address that was read out to you when you pressed ***1.
Enter "admin" for the user name and "admin" for the password.
This is the local webserver page for the OBi device. Navigate to System Management-->Device Update. Where it says "Select file to update firmware", click the "Choose file" button. Navigate to the firmware file you downloaded and select it. Press the Update button and watch. It should download the firmware to the device, install it and finally verify it and reboot. Be patient and above all, touch nothing; do not interrupt the process or you may turn it into a brick.
When it is done, pick up the phone and key in ***0 then 1# and confirm that it indeed updated to build 589EX.
Now, continue with my linked set of instructions, starting at this step:
- Now, plug in the Ethernet cable and go to the OBiTALK dashboard, and click the button to add a device. Follow the instructions to press **5 xxxx to add your device.
