Firmware updates for Smart TVs are used to enhance current features, fix bugs, and in some cases add additional applications to the device. You can perform the update via the Web (recommended). However, there are times where we may need to update via USB in order to resolve a problem.
What you'll need:
If you are updating via the web, your TV should be connected to the internet
If you are updating via USB drive, you'll need a computer with an internet connection and a USB drive with enough free storage space.
2. Update via Web
Press the Home button on the Sony remote control.
If ? (Help) is displayed in the top-right corner of the screen:
Select ? (Help).
Select Customer Support.
Select Software Update.
Select Yes to start installing the update.
If ? (Help) is NOT displayed in the top-right corner of the screen:
Select Settings.
Select Setup or Product Support.
Select Software Update.
Select Yes to start installing the update.
Your Sony Smart TV will restart and the update should now be installed.
Some older TVs only display an option to receive an Automatic Software Update. Be sure this option is set to On. This option will automatically search for software updates when the TV is in standby mode and you will be prompted to install the update once it is downloaded.
3. Enable Automatic Software Update
For Android TV Models:
Press the Home button on the remote control.
Select Help.
Select System software update.

If you do not know what your model number is, please check the sticker at the lower left corner of your TV's back panel.

5. Extract Zip File
In Windows, files typically download to your "Downloads" folder.

Click Extract when you are done.
Once the files are extracted, a new Explorer window will appear with the uncompressed files. The location will be shown in the address bar while the extracted files files will appear below.
Take note of the file location. This is where your file(s) will be extracted to.
6. Move Firmware to USB
Prepare a formatted USB flash memory with more available free space than the self-extracted file.
Insert a USB drive into an available USB slot on your computer.
Locate the file that you extracted earlier.
Right-click on the file, select Send to and then select your USB flash drive in the list.
The firmware will now be copied to the root of your USB drive. This is the first or top-most directory in the hierarchy.
7. Install Update via USB

Follow the on-screen instructions.
Once the update is done, your TV will restart automatically.
You can now remove the USB drive from your TV.
If you are having trouble, make sure that you downloaded the correct firmware file for your TV and make sure the folder on your USB drive is setup properly.
8. Extract Zip File
In macOS, files typically download to the Downloads folder in the Dock.
Click on Go then Downloads.
Double click on the archive that you just downloaded to extract its contents.
The extracted files should appear in the same folder as the original archive.
Sometimes you may not see the Zip file. Safari may have extracted the file for you if you downloaded the file with it. Just look for the unzipped file or folder.
Take note of the file location for later use of the extracted content.
