Did you flash the 5.0.4 main kernel image?
If you did, that might prevent the update to 5.0.4. You can flash a 5.0.0 main kernel image, but somebody needs to upload one and provide a link to it.
Or you can flash a main mmcblk0p1 image from a 5.0.4 kindle.
Another thing that can prevent updates to 5.0.3 or earlier is having changed files that the update wants to patch. The 5.0.4 update replaces entire files as needed instead of patching them, but it also updates the main kernel and may fail if that is not what it was looking for.
