Question [Kindle3] Match up tx/rx pins with tx/rx wires (bricked kindle 3, serial cable)

Hello folks!

I'm trying repair the k3 I bricked last summer

After quite some time I got hold of a FTDIchip USB cable with a rs232rg chip so that I can access the serial port.

In the cable's manual I found this scheme:

Black -> GND
Orange -> TX
Yellow -> RX

Hence I connected the ORANGE wire with the FIRST pin, the YELLOW with the SECOND and the BLACK with the THIRD. I'm sure the third it's right 'cause it's the ground.

Full of hope I tried to access my kindle using both Hyperterminal (win) and Minicom (linux) but to no avail.

For completeness sake the configuration I used is 115200 baud 8n1 with no flow control.

What am I doing wrong? Should I switch the tx/rx wires? I know I could just try and switch'em and see what happens but I'm not comfortable with this kind of things.

Could you please help?

Thank you

f
