I tried to update the firmware on my slingbox tuner a while back and something went wrong. The firmware only installed halfway and then I lost the remote connection I was using. So the Firmware on my slingbox is all messed up.

 What I want to do is return it to its factory specs and firmware but can't figure out how to do it. I tried contacting slingmedia help and they were not very helpfull.

 Do I just need to hold down the reset button for a certain period of time? I've tried for 10-15 seconds and it didn't work. 

 Any other ideas on how to hard reset my slingbox so it has the factory firmware again?

Thanks for your help.
