just plug the usb and get that the usb isn't recognized...I tried two cables and goes the same way...

And somehow works in Powershell with .\flasher I get all options

Flash it with W7, with this code

flasher -f -F main.bin -F emmc.bin --flash-only=mmc

(changing the path)

And was success but still have the old firmware...why? Made a comprehensive reset right?

Installed MeeFox and MeeGram2 and nothing...as you can seehttp://cloud.tapatalk.com/s/638a532f...163242_923.mp4

Nothing is going to work "out of the box" anymore, have a look at this resource to renew security certificates:

MeeFox requires dependency to be downloaded to enable installation:

Seems that my power button broken somehow and now I can't turn off the phone. Yesterday boot it, but wasn't able to turn it off. I've read here that by plug in can boot but my N9 just simply charge...what can I do?

you could type shutdown in the terminal

flasher -R to boot it (on PC, with Flasher installed)
shutdown command on phone or Reboot app to shut down

https://m.youtube.com/watch?v=svE0f-JKurI&t=619s he describes a way how to deal with broken power button, somewhere at the end of the video

could you upload the content of /usr/share/icons ? I would like to use then on sfos, but don't have my n9 anymore and couldn't open the .bin file with the firmware because the python script that was uploaded here isn't available anymore
