DX400 Factory Reset never completes

Hi I downloaded the latest ISO file and recreate the USB flash device.  Everything ran without error with the last message saying STORAGE OK.  I do the step to recreate my network, but seem doing nothing, cause still have the same issue.

I am not able to use the dashborad also unable to connect on remote.

I would like to reinstall the OS and re-start from the beginning of the installation.  Any idea of how to do this.  Thanks
