Here. This recovery flashable zip can be used for multi purpose. In this instance It's packaged with the Droid DNA boot animations including the HTC bootdown. If you want to remove the HTC bootdown then you can simply "open" the zip I have provided (open not extract) by using 7zip which is free to download
while you're inside the zip, navigate to system/customize/resource and you will see both animations in there. Delete downanimation.zip if all you want is the Droid bootanimation.
From here if you do get bored of the Droid animation then you could put any other compatible bootanimation.zip and it will change it as long as you don't change the spelling. It has to be bootanimation.zip
you can also add any apk file (apps) you have by navigating to system/app placing the apk file in this loacation. Saves a lot of time if you don't want to stuff around with a root explorer. Close the zip after you're done and there you have it.
