    You need to provide alot more details for anyone to be able to help.

    1. Firstly perhaps post a photo and/or schematic of your programming setup.
    2. What voltage are you supplying to the setup?
    3. What is the current limit of your supply?
    4. Can to see any connectivity to nrfGo Studio?
    5. If you are using a J-Link programmer there should be some error LED blinks. What are those? Have you cross referenced with the J-Link manual?
    6. Are you taking proper precautions with static electricity?
    7. What is the programmer clockspeed set to?
    8. What are the error messages seen from nrfjprog?
