Sat-Integral S-1412 HD ROCKET and S-1432 HD COMBO Firmware Recovery 2026

Restoring the operational status of the Sat-Integral S-1412 HD ROCKET satellite receiver becomes necessary when the device fails to boot after an unsuccessful software update. Typical symptoms include freezing on the boot logo (boot) or only the red power LED lighting up on the front panel.

Required Tools and Preparation

To recover the receiver, you will need the following hardware and software:

• Special flashing tool / loader (DownloadTool): Used to transfer the memory dump and firmware via a PC.

• RS-232 Cable: Hardware cable to connect the receiver to a desktop PC or laptop (a USB-to-RS-232 adapter is required if the computer lacks a built-in COM port).

• Firmware File (.bin): Official or recovery firmware for this model (for example, firmware version v1.24).

Step-by-Step Recovery Process

1. Software preparation on PC:

   • Download the archive containing the loader software (the link is usually provided in the description of official video guides on the Супутникове Телебачення channel).

   • Extract the archive to a convenient directory on your computer.

2. Hardware connection:

   • Connect the powered-off (unplugged from wall outlet) receiver to the computer using the RS-232 cable via the appropriate service ports.

3. Configuring DownloadTool:

   • Launch the application on your PC.

   • In the port settings, select the active Serial Port (e.g., COM1 or the one assigned to your USB-to-serial adapter).

   • Set the download mode to serialdown.

   • In the file selection field (File), specify the path to the previously downloaded firmware file with the .bin extension.

4. Starting the flashing process:

   • Click the Start button in the program window to enter communication standby mode.

   • Immediately plug the receiver's power cord into the electrical outlet. The software should detect the connection and start transferring data.

5. Waiting for procedure completion:

   • The process consists of several consecutive stages: erasing corrupted flash memory, writing the new data block, and verifying checksums (several upload cycles are performed).

   • Wait until the success notification (Completed) appears on the monitor screen.

Once the process finishes and the successful recovery notification appears on screen (Приймач вдалося відновлено / Ресивер успешно восстановлен), the receiver is ready to be disconnected from the PC and reconnected to the TV.
