Problem on nrf51.cpu: target state: halted

Hello guys, I installed everything and seems I can compile and all the code is being understood by arduino, however, when I am flashing the device I am getting these messages about halted cpu:

I am repurposing some old modules I had around, is it possible maybe those are write-protected?
