Dell XPS 13 (9370) + Aorus Gaming Box 1080: Thunderbolt NVM Firmware 40.00 doesn't recognize eGPU as a Thunderbolt Device
Yesterday i upgraded the Thunderbolt 3 firmware on my Dell XPS 13 9370 from 33.00 to 40.00. (Firmware file: Intel_TBT3_FW_UPDATE_NVM40_2670N_A03_4.40.24.002.exe)

I tried downgrading to version 33.00 using the FwUpdateCmd method outlined here, but i get the following error while running the procedure:
Are there any solutions to this?
