Nexus 9 bricked, no flash possible? topic

Hi All,

I think I just bricked my Nexus 9 while trying to disable the encryption (fastboot flash boot *noencryption.img*).

The Nexus 9 is unlocked but not rooted.

1. It will always restart to the bootloader again.
2. flash-all.sh script doesn't work:
2.1. flashing the recovery ends in ERROR: usb_write failed with status e00002ed
FAILED (data transfer failure (No such file or directory))
2.2. fastboot flash boot ends in: ERROR: could not clear input pipe; result e0004051, ignoring...
ERROR: could not clear output pipe; result e0004051, ignoring....
2.3. Nexus 9 is not reacting at all anymore (in bootloader)

I think this is the first nexus device (and I had the Gnex, Nexus 4, Nexus 5, both Nexus 7) where I am not able to restore the device after something went wrong.

Anyone an idea? Or is it ready to be trashed?
