Hello Robert Buffalo,
Thank you for visiting our Community.
It almost sounds like there may have been an error during your original firmware update. When it loops like that, that is generally the case. I would highly recommend doing a hard reset on the Slingbox itself. I've placed an article below referencing the reset process, just in case, as well as what may have happened to cause the issue in the first place.
- Slingbox.com - Trouble Updating Slingbox Firmware
- Slingbox.com - How to reset your Slingbox to factory settings
I hope this helps!
