What to do if the update is not found?

  • 🔄 Restart the TV and router.
  • 🌍 Change the DNS server to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in the network settings.
  • ⏳ Try checking for updates at different times of the day (servers Tele2 sometimes limit traffic during peak hours).
⚠️ Attention: If after updating via OTA, the TV starts to slow down, reset it to factory settings (Settings → Storage → Reset data). This will remove all applications, but will solve performance problems.

3. Method 2: Update via USB (for advanced users)

If OTA does not work, the only option is to manually install the firmware from a flash drive. This method requires more steps, but is guaranteed to bypass all blocking. Suitable for models: Tele2 TV Box (2020–2022), Tele2 Smart TV 4K (2023).

  1. Download the firmware for your model from the official website Tele2 or trusted sources (for example, 4PDA). The file name must contain the TV model (for example, Tele2_TV_Box_2021_11.0.42.zip).
  2. Prepare a USB drive:
    • Format: FAT32 (required!).
    • Size: up to 32 GB (large flash drives may not be readable).
    • The firmware file should be in the root of the disk (not in folders!).
  • Insert the flash drive into the USB port of the TV (it is better to use the port USB 2.0, if there are several).
  • Go to Settings → Storage → Update from USB (on some models the path: Settings → Device → Update Software → Local update).
  • Select the firmware file and confirm the installation. The process will take 10-15 minutes.
    • What to do if the TV does not see the flash drive?

    1. Try another USB drive (preferably an original one from a well-known brand).

    2. Reformat the flash drive to FAT32 using the utility GUIFormat (standard Windows formatting sometimes leaves artifacts).

    3. Check if the USB port on the TV is damaged (connect a mouse or keyboard).

    4. The flash drive is detected, but the firmware is not installed, rename the file to update.zip (sometimes it helps).
