Exit code (2) in Firmware update of simplertk2b-zedf9p

Hi friends,
I have been developing a autonomous rover with simplertk2b as a base station. So to set as a base station after a survey in. I surveyed the gnss receiver with the gnss antenna in an open sky. But it hasn’t changed to time mode after the survey in process. So, then I decided to change my old version 1.13 to new version of 1.51 from ublox website. but now I’m facing this error from my side
