STAR-X 99 Laser firmware from 25 February 2014, labelled new and shipped as a 3.12 MB ZIP. The 99 model also has Plus, FTA and WiFi builds, so the correct variant matters more than usual. A technician would load this onto a Laser unit to update its software or to bring back a dead receiver. Check the label and the current software before writing. Back up the existing firmware, because loading the wrong 99 variant can disable the receiver until it is reflashed.
