sybilvane, Is the firmware you are trying to flash a full version firmware or a backup dump.bin because after shorting the chip and placing the player into recovery mode (you should get a message that the player is in recovery mode when you open the upgrade tool) it will only accept a full version firmware. To check to see if it is a full version place the firmware into the s1fwx folder and then run the list.bat which will list the files inside the firmware.

In the info:afi section at the top there should be a list of 15-18 files like this

---[ info:afi ]----------------------------------------------------------------
file id = 'AFI '
vendor id = 0x10D6
product id = 0x1101
version = 9.0.43
date = 07/14/2006

If you only have a list of 5 files or less like this

---[ info:afi ]----------------------------------------------------------------
file id = 'AFI '
vendor id = 0x6977
product id = 0x6552
version = 3.5.37
date = 00/00/0000

+---filename---+ +---size---+ +-type-+ +---+ +--chksum--+
| BRECF641.BIN | | 16kb | | F641 | | B | | 0D60E814 |
| FWSCF641.BIN | | 11.5kb | | F641 | | F | | 68713593 |
| ADFUF641.AP | | 11kb | | F641 | | U | | E3032F26 |
| FWIMAGE.FW | | 6.55mb | | | | I | | 67E6F2AD |
| SYSINFO.BIN | | 192bytes | | | | | | CC5EB575 |
+--------------+ +----------+ +------+ +---+ +----------+

Then it is not a full version firmware and will not load to your player.
