Getting system updates
If your TV is connected to the Internet and linked with a Roku account, it will automatically get updates from time to time.
You don't need to do anything. But if you are aware that an update is available and you don't want to wait until your TV
updates itself, you can manually check for updates.
If your TV is not connected to the Internet, you can still get updates by using a USB flash drive.
You can download an updated User Guide that matches your Roku TV software version from the Sharp website at:
https://www.sharptvusa.com/support
To determine your current Roku TV software version, go to Settings > System > About, and then look at the Software
version line.
Checking for updates on a connected TV
If you're one of those people who has to have the latest, most up-to-date features the moment they are available, you can
check for updates as often as you want.
To check for updates, navigate to Settings > System > System update, and then select Check now. Your TV responds either
with a message saying that your TV is up to date, or with a message saying that an update is available.
Follow the instructions on the screen to install the system update.
Note
Sometimes system updates install new system software, and other times they install
new features for streaming channels. Therefore, you won't always see a change in the
behavior of your TV after a system update.
Getting updates on a non-connected TV
If your TV is not connected to the Internet, you can still get system updates by using a USB flash drive and a computer with
an Internet connection.
To get a system update, navigate to Settings > System > System update:
The System update screen on a non-connected TV gives you the opportunity to connect your TV to the Internet to
automatically receive updates. We recommend this option if it is possible in your situation. To proceed, select Connect to
the Internet and follow the instructions in
Otherwise, if you can't connect to the Internet, select I can't connect, and then follow the instructions on the screen. Here's
a summary:
1 On an Internet-connected computer, go to the website displayed on the System
update screen.
2 On the USB Update web page, select the correct brand and model and then click
Download. Save the file to the root folder of a standard USB flash drive.
3 When the download finishes, take the USB flash drive to your TV and plug it into
the USB port. When you do, your TV validates the files on the flash drive and
displays a 12-digit code.
4 Write down the code and the web address, and take this information back to
your Internet-connected computer.

USB flash drive
Any normal USB flash drive will work,
provided it has a FAT-16 or FAT-32 file
system format. (This is the default for
most flash drives.)
The size of the download is
small-usually less than 100 MB-and
so will fit on any size flash drive you
might have.
