Solution #3 Update Your Xfinity TV Box!

We need to keep our Xfinity Equipment up to date to have the latest version of the operating system, therefore as few bugs as possible.

The Xfinity Box restarts on its own at a pre-scheduled time every day to check and possibly install an available update.

When your internet connection is down during the process, the TV Box won’t update!

We can easily reschedule the Update Restart and test upgrading the firmware of our Xfinity Streaming Box right now!

Let’s learn how:

1. Press the Xfinity Button on your remote.
2. Navigate to the Settings.
3. From the settings menu, select Preferences.

In case there was a pending update, the Xfinity Streaming Box would perform the installation automatically now. Test whether Xfinity Code RDK-03036 appears after the restart.

Note: Your Xfinity Streaming Box will now restart every day at the scheduled time to check for new updates.

Solution #4 Change Power Outlet

Even if that sounds odd, sometimes the RDK errors can be caused due to power insufficiency, which prevents some of the fundamental operations of the TV box.

Since we’re already attempted power cycling the device, now we need to change the power source!

• Plug the Xfinity TV Box directly into the outlet without a power strip!

The repositioning will provide an additional restart after which your Xfinity TV Box should no longer bring up RDK-03036 error on the screen.

Feel free to test whether this helped!
