Android M Preview 2: "Error: Cannot Load System.img" I am trying to update my Nexus 9 to the M developer preview 2, and when I try to run the command fastboot flash system system.img, I get the error


  error: cannot load 'system.img'


I've tried re-downloading the image from Google and reflashing many times, but it gives the same error. I am able to flash other system images from Google, but not this one. I didn't see this listed as a known issue on Google. Anyone else see this issue or have any suggestions?
I faced the same error. Error cannot load system.img. I figured it out after few attempts and a few images. It turns out I had an older version of ADB and I could only install old factory images. 

If you want to install Android Marshmallow, make sure to install the latest ADB version.
