Hi, 
 Thank you for detailed description of your issue. Looking at the screenshots that you provided I can tell that you are using incorrect value of `--family` parameter during setting generation. Since nRF SDK for Thread 0.11.0, correct value for this parameter is NRF52840, not NRF52. In your scenario, the actual client application wasn't even loaded by the bootloader as it had stored settings under incorrect address, that's why you cannot see any DFU progress. The correct command should look like this: 
 nrfutil settings generate --family NRF52840 --application client\pca10056\blank\armgcc\_build
rf52840_xxaa.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 settings.hex 
 You can find it in the documentation for nRF SDK for Thread 0.11.0. 
 Regards, Robert Lubos
