.ROKU File Extension
What is a ROKU file?
Update.roku is a firmware update file used by a Roku TV. It contains data the TV uses to update to the latest version of the Roku TV software. Update.roku is used to update a Roku TV without connecting it to the Internet.
Typically, Roku TVs automatically update to the latest version of the Roku TV software. However, if a user's Roku TV is not connected to the Internet, they must manually update the device's software.
To manually update a Roku TV, users go to tvupdate.roku.com, enter their TV's specifications, and then receive a corresponding update.roku file. Users must then transfer the update.roku file to a USB flash drive, plug the drive into their Roku TV, and continue the update process.
How to open a ROKU file
Update.roku files are not meant to be opened. To use an update.roku file stored on a USB flash drive to update your Roku TV:
- Plug the flash drive into your Roku TV.
- Press the Home button on your Roku TV remote.
- Select Settings → System → System update → I can't connect.
Your Roku TV will then display a 12-digit code that you are meant to enter on your computer, at tvupdate.roku.com. After you enter the 12-digit code, your computer will display a six-digit code that you must enter on your Roku TV, to complete the update process.
