Roku Can't Update Software Error 004

Switch to a Different Internet Connection:
- If possible, connect your Roku device to a different Wi-Fi network or use a mobile hotspot. Some users have found success by doing this, especially if their primary network is experiencing issues.
Restart Your Roku Device and Network Equipment:
- Unplug your Roku device and your router/modem from the power source.
- Wait for about 1-2 minutes.
- Plug them back in and allow them to fully reboot.
- Once the network is stable, attempt the update again.
Use a Wired Ethernet Connection:
- If your Roku device supports Ethernet connectivity, connect it directly to your router using an Ethernet cable. This can provide a more stable and faster connection, potentially resolving update issues.
Remove and Reconnect Your Network:
- Navigate to Settings > Network > Set up connection on your Roku device.
- Forget your current network and reconnect by entering your Wi-Fi credentials again.
Perform a Factory Reset:
- If other methods don’t work, consider performing a factory reset:
  - Press the Home button on your Roku remote.
  - Go to Settings > System > Advanced system settings > Factory reset.
  - Follow the on-screen instructions to complete the reset.
Manually Update Roku Software:
- Download the latest Roku software to a USB drive from the official Roku website.
- Insert the USB drive into your Roku device.
- Follow the on-screen prompts to install the update manually.

Additional Tip:

Check for Network Interference: Ensure there are no physical obstructions or electronic devices causing interference between your Roku device and the router. Reducing such interference can improve connectivity and update success rates.
