I ran out of idea on what could be wrong, you would need to capture a sniffer trace and we can check what happened. From the log you post at the beginning, seems like nRFToolbox couldn't find DFU version on the nRF51.

Could you please update the screenshot on the phone:

• When you see the issue happens in nRFToolbox

• What you see when using nRFConnect to connect and discovery service.
