pmcoz2 , at the moment, the firmware extraction tool S1fwx does support any versions higher than v9.0.43. So others with a working v9.0.48 could not extract theirs to upload to the forum.
However, i'll suggest you try every v9.0.xx firmwares here

If they do not work, then you can't do anything about it and wait till the tool supports your version.
