Software for the StarTrack SRT-5500 New HD Plus receiver, dated 29 April 2018, supplied as a 3.14 MB RAR archive. It serves to reinstall or update the system firmware on a box that freezes, loses its menu or will not start correctly. Extract it and check for instructions on the update method, usually USB. Confirm the exact model, as the New variant may differ from the original SRT-5500 hardware, export channel lists first and keep power stable until the receiver restarts.
