In the world of budget-friendly smart televisions, Supra TV has carved out a significant niche. Known for offering large screens at competitive prices, Supra TVs often run on customized versions of Android TV or Linux-based operating systems.

Important Warnings

Never unplug the TV during an update – This can brick the device (make it unusable).
Do not interrupt the power – Use a UPS (battery backup) if your area has frequent blackouts.
Only use official firmware – Installing modified or incorrect firmware can permanently damage your Supra TV and void the warranty.
Back up your settings – Some updates may reset picture or network settings to default. Write down your Wi-Fi password and preferred picture mode.

Method B: Manual Update via USB (For Non-Android or Offline TVs)

Use this if the TV has no internet connection or if the OTA update fails.

Step 1: Check your Current Version

Go to Settings > About > Build Number or Software Version.
Write this code down (e.g., SUPRA-LED42-2021-V2).

Step 2: Find the Firmware

Go to the official Supra website (usually supra.ru or the regional site for your country).
Navigate to Support > Downloads or Firmware.
Search for your specific TV Model Number (found on the back of the TV or in the box, e.g., `STV-LC40T760FL**).
CRITICAL: Ensure the firmware version on the site is newer than the one you wrote down. Do not flash the same version or an older version.

Step 3: Prepare the USB Drive

Use a USB Flash Drive formatted to FAT32 (this is the most common error—NTFS or exFAT often will not work).
Download the update file (usually a .zip or .rar file).
Extract the file. You usually need the specific file inside (often named update.zip or supra_update.bin).
Important: Copy the file to the Root Directory of the USB drive (do not put it inside a folder).

Step 4: Install

Turn on the TV.
Insert the USB drive into the port labeled USB 2.0 or Service (preferably USB 2.0/3.0 if Service port is not accessible).
The TV should automatically detect the drive and prompt: "New upgrade software found. Upgrade now?"
Select Yes/OK.
DO NOT UNPLUG THE TV OR USB. Wait for the progress bar to reach 100% and for the TV to reboot.
