Our application implements OTA upgrade.  We recently inadvertently upgraded a 20732 based board with firmware for the 20736.

Is there any method to recover from this?  When I try to reprogram the bricked device over serial it fails saying it cannot load the minidriver.

Is this device permanently unrecoverable?

Use the recovery procedure for 20732(S) from SDK 1.1 quick start guide and SDK 1.1 to download the new image.
