felixng , the problem is currently there are no tools supporting firmware extraction for your version. The only firmware extraction tool S1fwx only supports upto v9.0.43 at the moment. So others could not extract their firmware for you to try.
However, do try the other v9.xx firmwares here

Sometimes it might just work. Good luck.
