Hello everyone!

I tried to go in the app DriveDroid but the app showed me this message :
"They are no images in your image-directory. Please download an image with the download button.
You can also manually download images (like .iso or .img) and place them in the following directory:

/storage/emulated/0/Download/Images"

I have tried to access to the .iso for Kali Linux but there was not the image for NetHunter, please could you help me?
