I am trying to restore the DTK following the instructions from https://download.developer.apple.com/Documentation/Universal_App_Quick_Start_Program_Resources/Restoring_Developer_Transition_Kit.pdf.
When dragging the IPSW file to the configurator, the restore process starts but soon fails with:
"The System cannot be restored on this device. Failed to copy preflight options during recover mode restore. [com.apple.MobileDevice.MobileRestore - 0xB (11)]"
Any suggestions for getting the restore to work?
The DTK is connected to a macOS 11 beta 9 VM that has Xcode 12.2 beta and Configuration 2.13 installed.

I have it figured out. The key was the following:
I thought I had trouble putting the DTK in DFU mode, since it had so sign of life. I was resetting the power cable until DTK would chime and LED would show. That was a mistake. After rereading some of the posts, I realized that DTK was in DFU mode with no chime/LED/fan. I followed the directions in the guide and was able to restore DTK.
from @mikeboss post on https://developer.apple.com/forums/thread/661096?answerId=634483022#634483022.EVEN IF THE DTK PLAYS DEAD (NO FAN, NO POWER LED, NO BOOT CHIME, NO OUTPUT ON DISPLAY) IT SHOULD BE IN DFU MODE NOW.
