Software for the StarSat SR-B10HD Prime receiver, described in the name as supporting auto roll PowerVu, stored as a 2.99 MB ZIP. It is a firmware build that adds PowerVu auto roll handling, a feature used on some satellite services. Load it with the receiver's USB upgrade option or a serial loader after confirming that the model is the B10 and not the C10. Before replacing the factory image, save a backup of the existing firmware, because modified builds can behave differently and may need reverting.
