: Websites like Firmware Today or All Receiver Software aggregate dump files for Sunplus, Montage, and GX-based mini receivers.

Could you tell me the of the receiver (e.g., StarTrack, Tiger, or MediaStar) or the chipset printed on the board? This will help me find the exact download link for you.

: Ensure the dump matches your receiver’s chipset (e.g., Sunplus 1506G, GX6605S). Using the wrong file can permanently brick your device.

: Since you are looking for a .rar file, you will need a utility like WinRAR or 7-Zip to extract the .bin file inside before transferring it to a USB or programmer.

: If possible, use a programmer (like the CH341A) to dump your current flash memory before overwriting it.
