Did I damage my NodeMCU?

I connected a 10k pull-up resistor at D0 pin of my NodeMCU.
Then I removed it.
But since then it stopped working, olnly the LED lights up and remains lit.
Is it possible to damage it just by connecting a pulll-up resistor at D0?

Except from connecting a pull-up resistor to D0, I had made and a second change: I had connected in the circuit and D4 (GPIO2)...
This was the problem, I suppose D4 was going LOW and so ESP could not reset...
