Nexus 9 Failed Android M Update from Factory Image. Cannot access the current OS.

I tried to follow the instructions given on google's website. Downloaded the factory image, unzipped files and folders as told. The OEM is unlocked.

When I ran the flash-all script, I got the following messages.

error: update package missing system.img

After this, I cannot use my OS. Tried going into recovery, still does not help.

The only screen that is accessible is the Bootloader screen.

Device State is now unlocked.

I have never flashed any Android systems, but I know that this is a very common and can be fixed by manually flashing each individual file using commands in the Android sdk rather than running the flashall script.

You need to update your SDK. They fixed the missing system.img error in rev. 23 several months ago.
