I had somewhat of the same problem on my MarkV
Here is what i did
1. Power Off
2. Put LAST dip switch down
3. Power on for 5 minutes
4. Powered Off
5. Reset LAST dip switch up
6. Powered On
7. Let sit for about 5 minutes
After that i went to the browser and saw the upgrade to 2.0.4 was complete
One issue i am having in recon view is that i cannot see clients. Only access points. It doesnt matter what i set it to.
Im using Ubuntu Firefox 32
