Unable to Flash Jetson TX2 NX with Jetson Mate

Following the wiki with Jetson Nano modules had no problems… But unable to flash a TX2 NX module.

SDK Manager
lsusb shows the jetson TX2 NX module booted in recovery mode (jumper inserted in jetson mate)

The sdk manager is correctly sees the TX2 NX module and creates the OS image… But cannot flash it.

The target is in a bad state
The Jetson arget is in a bad state and cannot be flashed.Please manually put the trarget into recovery mode and then try flashing

The Jetson Mate is advertised to work with NX modules why can’t it be flashed?

Please advise!
