Hi there, I'm very sorry that you are experiencing issues with your CU7000 TV Software. Please know we are here to help. First, let's try to run a cold boot on your TV. Hold down the power button on your TV remote until the TV shuts off and turns back on again. Then go to Settings> Support> Software Update. If you still cannot update your TV, you can download the update on a USB drive and manually update your TV: 1. On Samsung's website (upper right corner), go to Support > Manuals & Software > Find your TV model. 2. Download the update and extract it to the root of a USB thumb drive. (Do not put it in any folders on the thumb drive.) 3. Connect the USB thumb drive to a USB port on your TV. 4. Navigate to Settings > Support > Software Update, select Update Now, and then select Yes. 5. Follow the on-screen instructions to install the updated software. I hope this resolves your issue! If you continue to have issues, please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. LiveChat with an agent, as well as manuals, software, and warranty info, can be found at the ‘Support’ link on our Samsung website. ~ Samsung Advisor
