Cloning HID to xEM

Hello!

Finally got my proxmark3! I a trying to clone a HID Prox fob to my xEM and struggling a bit. I am able to read the Prox fob and read the xEM as an EM410x but I haven’t been able to write to xEM. I am using the Gaucho GUI and the HID Clone function.

Any help would be appreciated!

Thanks!
