Of course the tool initially found that it is NOT a Samsung writer and

CD-R/RW SW-208B" into "CREATIVE CD-RW RW8435E " (mind the extra
space). Then the tool recognized the writer and started the upgrade
process. But failed after 99%...

Using Notepad (or any other text-editor) for that, was a very, very bad
idea. Text-editors will modify the file in a destructive way (they think
there are line-breaks in there, but that's not true for a binary file). You
should use a hex-editor for that, which would allow you to change only what
you want, not messing up the whole file. Text-editors are for text-files,
not binary ones. Don't do it again.
