Obtaining the downloader and firmware
- Get the ali-rs232-upgrade-tool-v1-2-0 binary from the device vendor or official support site. If vendor provides source or signed package, prefer that.
- Verify integrity (checksums/signatures) if available.
- If only archived in community forums, be cautious — check hashes and cross-reference with other sources.
- Also obtain the exact firmware image(s): model-specific .img/.bin files, and any parameter/partition config files the tool requires.
Step-by-Step Guide
- Install Drivers: If using a USB-to-Serial adapter, install its drivers on your PC. Check Device Manager to see which COM port was assigned (e.g., COM3, COM4).
- Connect the Hardware: Connect the RS232 cable to your PC and the serial port on the back of your satellite receiver. Ensure the receiver is plugged into power but turned OFF (standby).
- Launch the Tool: Run
Ali_Rs232_Upgrade_Tool_V1.2.0.exe as Administrator.
- Configure Settings:
- Select the correct COM Port.
- Set the Baud Rate (usually 115200 for modern updates, though some older boxes require lower speeds).
- Select Firmware: Click "Browse" or "File" to select the firmware
.bin file you downloaded.
- Initiate Transfer: Click the "Start" or "Upgrade" button in the software.
- Power On the Device: Immediately after clicking Start, switch the receiver ON using the rear switch or plug it in. The tool should detect the bootloader and begin writing data.
- Wait for Completion: Do not touch the device or PC until the progress bar reaches 100% and the tool displays a "Success" or "Finish" message. The device will typically reboot automatically.
Step 3: Configure the Tool
- In the GUI, select the correct COM port (e.g., COM3).

115200 (default) – use 38400 if the device is old.
