Firmware archive for the Geant GN-77 HD satellite receiver, software version V167 dated 20180520, stored as a 14.1 MB RAR. The size suggests it may hold more than a single image, such as several files, a channel list or flashing tools. Repair shops use it to revive receivers stuck on boot or to update the software. Extract it and read any included instructions before choosing USB or serial loading. Confirm the exact model on the label, and back up the existing flash before writing in case recovery is needed.
