Roku TV is one of the most affordable streaming devices available out there. It provides 4K quality video services, and many apps are available in it. To handle all those apps, it needs to regularly update its software. But while updating its software Roku nowadays comes up with error code 003. Which basically translates to a device unable to translate. A bad Internet connection can sometimes be the cause, but more often than not, people have reported that they are getting this issue even when their Internet connection is fine.
There could be two possibilities. It’s possible that the server is down or that Roku is unable to connect to the Internet. We will try various types of troubleshooting Roku error code 003 in this article.
Ways to Troubleshoot Roku Error Code 003
The following are some of the working methods that can be used to fix the Roku Error Code 003.
Checking whether servers are down
The first and foremost thing that should be done is to check whether the servers are down. Before we proceed to alter your network settings, it’s a good idea to see if Roku’s backend servers are having problems. Nothing you can do will get you connected if the servers are unavailable or undergoing maintenance. When Roku servers aren’t working or are down, you’ll get error code 003. You can use downdetector or by accessing Roku’s official page to check this. You may check the current status of Roku servers right here. Check to see if the Roku servers are up and running. You may encounter error code 003 if the Roku servers are unavailable. You may also observe whether or not other Roku users are having problems.
If this is the case, you won’t be able to do anything about it. You’ll have to wait for Roku’s servers to repair this. You’ll be able to download and install the latest version of Roku’s firmware without trouble once Roku’s issue is rectified.
Restarting Roku to Fix Error Code 003
If the servers are not down, you can try on this method.
Restarting your Roku device will sometimes help you re-establish your internet connection. You’ll be able to upgrade your Roku device without any problems after that. Follow the steps below to restart your Roku.
 On your Roku remote, press the Home button and select the Settings option.
 Select System by scrolling down. Next, scroll down and select System Restart once more.
 Select the Restart option.
The system will restart, causing it to become a soft reset, thus helping to delete any bug causing the 003 error code.
Checking internet connectivity
If you don’t have a good internet connection while updating your Roku device, you’ll get error code 003. Visit speedtest.net to see if your internet connection is up to par. You may also check your internet connection on your phone or computer. Check if the Wi-Fi is operating properly using a browser or an app such as YouTube. Ascertain that your Roku TV is linked to the appropriate Wi-Fi network. Move your router closer to your Roku device to boost your internet connection. This will strengthen the internet connection and may aid in the resolution of the Roku update problem 003. Also, make sure Roku and your router aren’t in any way interfering.
Using an ethernet network is better for Roku or any other streaming service than a wireless network. It’s quite simple to set up the connection; all you have to do is take an ethernet cable and plug one end into your Router and the other end into the device you’re streaming on.
Now try updating Roku again; hopefully, this time, it will work.
Switching Network Security Protocol
As previously stated, Roku is not a fan of AES methods used in network security. There have been a few instances where Roku has refused to update/connect due to the network’s protocol. We can change the protocol to see if it solves the problem. Be careful because you are updating the security settings on your network at your own risk.
 Open your router’s settings and look for the IP address in the IP address field. This address is usually located on the router’s back panel or in its manuals. It’s something along the lines of 192.168.8.1.
 Navigate to Wireless or Security in settings and make sure the security mode is not set to AES in any way. WPAK2-PSK is one option (TKIP).
 After you’ve changed the security mechanism, try connecting to the network with your Roku using the new settings. Check to see whether the problem has been resolved.
Updating your Roku
As this error is basically caused due to not being able to complete the update. It is a very good idea to just try updating the firmware again. To update your Roku TV, follow these instructions step by step:
 Press the “Home” button on your Roku remote. Select System from the left pane under Settings.
 Select the System Update option and choose Check Now.
 If an update is found, select the Update Now button. During or after the update, the television may automatically reboot.
Remember not to unplug or switch off your smart TV while it is updating. After that, see if the issue still occurs.
