So i did every curl get.pimoroni.com/blahblah and everything seems to be working. BUT my Inky Phat is not working at all. But my speaker phat is working well ! I’m using a ZeroW, I tried over multiples PS (3A, 5.1V/2.5 and 1A)

I double checked the pinout :

But I really don’t understand. I did test over a RPi-3B+ to see if my solderings are not good, but it fails…

Thank you in advance !

Could you post a picture of your setup? It’d help immensely with the debugging process.
