The flasher is a command line tool, so you need to open the command prompt (cmd.exe) and from there execute the commands e.g: Code: flasher -f -F main.bin --erase-user-data=secure
flasher -f -F main.bin --erase-user-data=secure
Also, remember to use "cd /path/to/where/you/downloaded/flasher" And, put the firmware images in the same folder as flasher, so You don't need to provide full path to firmware images.
