If you have a hard drive, try removing and adding the hard drive again . After replacing the storage device, try the update again. If this does not resolve this issue, please proceed to the next solution. Solution 5: Update via a USB Flash Drive or CD-R The next step would be to update your console using a downloaded file on USB Flash Drive or CD-R prepared in your PC. This method can also be used to apply the update to consoles that do not have access to LIVE. Copy to a USB flash drive If you cannot connect your Xbox 360 console to the Internet, you can copy the console update from your computer to a USB flash drive and then install it on the console. Note The USB flash drive must use the FAT32 file system. Plug your USB flash drive into a USB port on your computer. Download the update file . Click Save to save the console update .zip file on your computer. Unzip the file. If you are using Windows XP, Windows Vista, or Windows 7, double-click the .zip file to unzip it. Copy the contents of the .zip file to the root directory of your flash drive. Unplug the USB flash drive from your computer. Plug the flash drive into a USB port on your Xbox 360 console. Restart the console. When the console restarts, the installation program starts automatically. Select Yes when you are prompted to update the new console software. Burn to a CD or DVD You can update your Xbox 360 console software by downloading the update to your computer from Xbox.com, burning the update to a CD or DVD, and then installing the update on your console. Here's how: On your computer, download the update file . Click Save to save the console update .zip file on your computer. Unzip the file. If you are using Windows XP, Windows Vista, or Windows 7, double-click the .zip file to unzip it. If you are using Windows XP, Windows Vista, or Windows 7, double-click the .zip file to unzip it. If you are using an earlier version of Windows, you need to use a special software program to unzip the file (for example, WinZip). Insert a blank, writeable CD or DVD into your computer. Copy the contents of the .zip file to the root directory on your CD or DVD, and choose to write (burn) the files to the disc. Once the files have been burned to disc, remove that disc from your computer and insert it into the disc drive on your Xbox 360 console. Restart the console. When the console restarts, the installation program starts automatically. Select Yes when you are prompted to update the new console software. If the issue still persists, please continue to Solution 6. Solution 6: Simplify your Network Setup Sometimes, there is a firewall on your router or modem that is blocking the update from being downloaded. In this case, the fastest way to get that update on your console is simplifying your network setup. To do so: Establish a direct connection between your console and your modem via an ethernet cable. There should be no other devices plugged into your modem at this point. This will completely bypassing your router or switch (and it's update-blocking firewall!) in the process. If you have a gateway, you can accomplish the same thing by setting your gateway to "Bridged" mode (please refer to your gateway instructions for information on how to perform this.) This is only a temporary step until the update has been downloaded and installed! Once you have completed the update process, you can revert back to your normal network configuration. If you cannot perform this step due to wireless connections or a Gateway without a "Bridged" mode, please view Solution 6. Solution 7: Disable your firewall For this, you would need to refer to your router or gateway's manual for help. Usually, there is a way to completely disable the firewall on your network device. Again, this would be temporary, and you would only have your console connected to your gateway or router so as to not expose PCs or other devices to risk. Once you have disabled the firewall, restart your console and try to accept the update again. Once you are finished downloading the update, please do NOT forget to turn your firewall back on! Leaving your firewall off will expose your PCs or other network devices directly to the internet, which is dangerous! Solution 8: Check out your error code for specific instructions. If you still are not able to get the update downloaded or installed, you are probably receiving an error code, which is typically 6 groups of 4 digits (or letters.)
