When reaching 9006 mode, the Blue led indicates downloading mode.
Make sure that "program bootloaders" is activated.
Make also sure that you are not using USB3.0 ports.
The process feels the same about memory, it overwrites every image on your device memory space.
You need to make sure mmc is disabled, program bootloaders enabled, and the com port has detected your device in sahara (or download) mode.

fastboot.exe getvar all
And paste here what you get.
