TV Firmware Update via the Internet

If your TV is able to connect to the Internet, you can update the Roku TV firmware through the following steps:

Step 1: Press the Home button on your Roku remote.

Step 2: Go to Settings > System > System update.

Step 3: Select Check Now to manually check for updates.

Step 4: If new software is available or updates are available for your channel, your Roku device will automatically download and install them, and once done, your Roku device will reboot.

Sometimes, however, a lot of users failed to get the TV firmware update using the Internet. If the TV firmware update cannot be connected to the Internet, you can try updating the firmware using a USB flash drive.

TV Firmware Update via a USB Drive

Another way for the TV firmware update is to use a USB drive. How to do that? Here is the guide:

Step 1: Open a web browser and visit this site. Then choose the mode of your Roku TV (e.g., TCL)

Step 2: Enter your Roku Model Number and Serial Number. The model number is displayed as 4 numbers followed by a letter (e.g., 6104X) and the serial number is a combination of 12 numbers and/or letters. To find this information, go to Settings > System > About on your Roku TV.

Step 3: Select Download Software to get the update.roku installer file downloaded to your computer. Then locate the update.roku file on your computer. By default, it is often in a Downloads folder.


If it is not in the downloads folder, it means that the user has changed the path stored in the browser, you can go to the browser settings to find it.

Step 4: Prepare a USB flash drive and format it to FAT. In general, the file system is FAT32. If the USB flash drive is larger than 2GB, choose FAT32. If it is less than 2GB, choose FAT16. You can do that using Windows File Explorer.


Sometimes, the USB flash drive may be larger than 32GB and you can’t format it to FAT32 using Windows built-in utilities. However, MiniTool Partition Wizard can help you do that. It can format a USB flash drive up to 2TB to FAT32.
