oh i get it you cant even run flasher. which flasher file did you get I suggest heavily that you get winflasher 3.12.1 and what os are you trying to run it from? Have you already downloaded the image from navifirm? DId you notice that there are quite a few files on navifirm always make sure the bin file with dfl 61 and legacy written on it is downloaded. It should be quite big. put that file in the flasher folder where flasher.exe is. now rename the bin file to something smaller i just renamed it to 686_arm.bin. Now if you are running windows open command prompt...I assume you know how to navigate to any directory using command prompt...then go to the flasher folder where the bin file the flasher.exe file is, now type the command given on the instruction.

"flasher -F FIRMWAREIMAGE.bin -f"

Now instead of FIRMWAREIMAGE you type the name of the file you gave the bin file....in my case my command was

'flasher -F 686_arm.bin -f'

and you should be good to go...another command prompt window should open up saying waiting at the end/ Turn off your N9 wait like a few seconds and then plug in the device. when that second window closes you are done, unplug it and the phone turns on by itself and voila!

Hope this helps and I hope I didnt offend you by mentioning unnecessary steps because I have no idea what your ur knowledge level is.
