Sorry, I thought I understood that you were using the Pongo Skin.

With the Waldek Skin you cannot use the "gpsandmore_generic.zip" file like loading because a file with that name already exists.

The loading image in this Skin You can be found in the_skin/ui_nextgen/res/the_dark/(xxxhdpi-xxhdpi-xhdpi-mdpi-ldpi-hdpi)/loading.png

Vectorizing images is particularly complicated, especially with very complex ones, luckily it can also be remedied by using PNG images, in this way almost everyone is able to customize the loading image to their liking.

I have problems with attachments but you can download the images from below:
