Hello @JacekKac,

the problem is either

1. The firmware file is of a recent version and is therefore not supported by this library,
2. or there's a flaw in the parsing logic (which I would have to verify)

If you are sure the latter one is causing the problem, it would be nice to share the file for investigation.
