Are you using softdevice s130_nrf51_2.0.0? What output are you getting from the nrfutil command? Also, take a look at this devzone case here. Make sure you are using the correct softdevice (SD) code after the --sd-req command. It seems like the correct SD for SDK 12.3.0 is the s130 v2.0.1 SD. Which would make the code 0x87. But double check to make sure you are using the same SD. You can find the different SD codes by typing nrfutil pkg generate --help in a command prompt window.
