Yes, I uderstand that, but here's the problem: I have changed only small details on the part of the file which is gonna stay "solid" so the properties in corresponding .dat file which (I assume) describes which portions of the bitmap will become transparent/semi-transparent (like a mask) should stay unchanged as well...
The HEX value of the surrounding "black" in the modified bitmap is exactly the same as in the original file. Where the original file is transparent the modified one shows solid black...
Here are two examples.
This is how the file is supposed to look like (original file):

And here is how it looks like (modified file):
