Updating or recovering this specific board can be done via USB for functioning devices or via RS232 "loader" software if the device is stuck on a "Red Light" or "Load" screen. 1. USB Update Method (Standard)
Use this method for regular firmware updates or adding features like new satellite keys. Format USB Drive : Ensure your USB drive is formatted to File Preparation : Copy the firmware file (typically named Recommendation: If you are a developer or student
or a specific version name) to the root directory of the USB. Installation Insert the USB into the receiver. Navigate to Menu > Setting > Upgrade > USB Upgrade Select the file and press . Do not turn off the power during this process. 2. USB Recovery Method ("Dead" Receiver)
If your receiver shows "Load" or is stuck on a logo, you can often force a recovery without a PC. Rename File : Rename your working firmware file to Force Flash Power off the receiver completely. Insert the USB containing only the Power on the receiver while repeatedly pressing the button (or Exit/OK on some remotes). The screen should show an "Upgrading" progress bar. 3. RS232 Loader Method (Advanced)
If the USB methods fail, use a PC with a serial cable (RS232 to 3.5mm jack or DB9). Tools Required : Sunplus 1506G Loader software (e.g., Console Downloader). Connect the receiver to the PC. Open the Loader, select the correct , and load your firmware file. in the software, then plug in the receiver's power adapter. Wait for the "Complete" message before disconnecting.
