You need to get a 1.8 V or 3.3 V USB to TTL converter board (see the numerous serial cable jailbreak tutorials on this forum for the recommended board). I personally use a Chinese part that consists of a red board with six pins sticking out of the bottom. It's a clone of the FTDI FT232RL, and is available for pocket change on eBay and (for a little more) at electronics stores. If you use that board, make sure you set the jumper to 3.3 V.
You need to "read" the output of the serial port to see what's causing the error. Actually, you're lucky to have a signal on the pins on that board ... it's going to be of great help.

I have something i got some time back, it's a red board with 5 pins sticking out and no jumper, so i guess i need to solder RX TX GND?
This is the guide i found

I only have the adapter no serial cable, i'm assuming if i connect the adapter to a usb port and solder the pins to the kindle board it should work but what bothers me is the voltage you mentioned since my board doesn't have a jumper just pins, here is a link
