  • First, check whether already your smart TV is running on the latest firmware. Then there is no need to separately re-install it once again.
  • Use your TV remote to press the Help Button. You will get to see the model of the TV and the software version. If it matches with the latest firmware version, then no need to re-update.
  • Do not switch off your TV while the upgrade process is going on.

How to Automatically Check for Update

If you do not want to follow the manual way of the firmware update, then you can wait for the smart TV to download and install updates on its own.

  • On your remote control press the HELP button
  • Then select System software update > Automatically check for update.

If an update is available then that will be installed automatically. Sometimes it may take a few days or weeks for the update to show up on your device. Normally, the OTA updates rollout gradually based on the geographical location of the device. So, before manually upgrading wait for a few days for the update to become available on its own.

Manual Firmware Update

  • Download the firmware from the link posted above
  • Extract the image from the zip file
  • Connect the USB flash drive to the PC
  • Copy the extracted firmware file to the USB drive and then disconnect it from the PC
  • Turn on the TV
  • Then insert the USB drive into any USB Port of the TV
  • Follow the instructions and do accordingly as instructed on the screen.
  • Power LED on the TV will flash as the update begins
  • TV may turn on or off on its own while updating. Do not touch any buttons or turn it off on your own.
  • Once the update finishes up, the TV will restart on its own.
  • As the update completes, make sure to remove the USB drive from the smart TV.

All your previous settings will be intact and similar to what it was on the previous firmware version. So, now that firmware update is complete on your Sony Smart TV, you can enjoy your favorite shows seamlessly. I hope that this guide was useful to you.
