[HOW TO FLASH] how to flash Qviart OG2 OTT 4K

To flash the Qviart OG2 OTT 4K, you need to use the “Emergency Recovery” method. This model is a dedicated OTT (Over-the-Top) IPTV box running a specialized Linux OS, so the process differs slightly from the standard S2 satellite models.

Preparation

1. USB Drive: Use a USB 2.0 stick (max 8GB) formatted to FAT32.

    

2. Download Image: Ensure you have the specific firmware for the OG2 OTT 4K (not the S2 or standard OG model).

3. Extract Files: Unzip the archive. You should see a folder named update.

4. Copy to USB: Place the update folder in the root of the USB drive.

   • Structure: USB Stick -> update -> (files like usb_update.bin).

The Flashing Process

1. Power Down: Unplug the power adapter from the back of the OG2 OTT.

2. Insert USB: Plug the USB stick into the side USB port.

3. Initiate Recovery:

   • Locate the Reset button (usually a small pinhole on the back or bottom).

   • Using a paperclip, press and hold the Reset button.

   • While holding it, plug the power adapter back in.

4. Trigger Update: * Keep holding the Reset button for about 5–8 seconds until the TV screen shows the Qviart Boot Menu or a blue progress bar.

   • If a menu appears, select “Update via USB” using the remote.

5. Wait: The system will begin writing the firmware. Do not touch the power cable during this time.

6. Complete: The box will reboot automatically into the new interface. Once the language selection screen appears, you can remove the USB stick.

Important Tips

• LED Feedback: The front LED will often blink or change color (e.g., from Red to Blue) during the flashing process.

• File Verification: If the box boots normally to the old menu, it means the update folder wasn’t recognized. Double-check that the folder is at the root level and not buried inside another folder.
