There are lots of other people here that can help.
What heavypioneer mentioned is correct. The latest 9.0.43 can't be used with s1fwx at the moment.
There are lots of FULL FIRMWARE available from here:

You need to try them all to find the one that works for your player. Then find another firmware that will give it back it's functions like it was originally.
Good luck.
