@mitu I used a Sandisk Ultra 32GB MicroSD HC I the first time and worked fine. The other memory stick I used is the Micro SDXC 10 256GB MicroSD XC 1 1 (This memory stick I the one that’s giving me troubles). The power supply I used was a EasyAcc 5V 2A Micro USB power supply. The raspberry pi zero w was purchased from the adafruit website.
