I keep getting this error when i try to write the firmware:
error: failed to transfer data for giveio command: stx


Heres the full thing to give an idea of what options i used:

Anyone know why i get this error? I upgraded my mp3 player with the wrong firmware, but i backed my original one up and am trying to somehow get it to the mp3 player.

Wieee!! I will start from the begining.
I tryed to upgrade my player with new firmware, but it was wrong. so i have a loading screen with a sand watches. then i found out that it's not ADFU usb device, but s1mp3 device. firmware update tool, wasn't recognising it. so when when i was installing driver, i delete libusb driver, and rename adfu driver with libusb driver files names. (directory, .sys file) and add .dll file as it is.
now firmware update tool recognized player and i update it with v9.0.50 firmware
