Profile Installation Failed The profile "com.kace.cloud.mobileconfig.mdmconfig" must be installed interactively
This is an Apple issue. To get the phone un-bricked it seems that DFU mode might be the only way out, but possibly un-assigning the device from the DEP profile, resetting, and then upgrading to the latest version of iOS, then re-assigning the device and resetting it would be the easiest thing to do, but this maybe will not work.
Here is the information about how to put the iPhone in DFU mode.
