Tonymac boot loader theme gone

[pepejeria]

I was doing some minor changes to config.plist and I was surprised to see that the Clover theme was changed to a white theme instead of the black one provided by tonymacx86. I am a beginner so please bear with me. How could this happen?

IMG_2581 shows the new replaced boot theme
IMG_2582 show that the theme can be changed
IMG_2584 shows the tonymac theme embedded in the new theme once changed

The Hackintosh no longer boots since this happened, but that would be another issue unrelated to my question above.
