Pretty much the same nonsense. I tested yours and mine and both seem to have somehow same size and both dont work...
S1clone does not work (Semaphore...) same for S1res and S1fwx does create this trashy file.

Can sb help with this device:
6th gen Nano
I want to extract the Firmware, change the UI with S1res and flash the edited firmware back on the Player.
