Kindle Touch serial port recovery

Hi guys,
so I've been trying to rescue my Kindle 4 Touch (one day it just started a reboot loop). I've tried every debrick method I've found online (including kubrick and other guides from this forum), but it seems my Kindle is stuck in "fake usb mode" or whatever you call it - for example flashing diags partition seems to go ok, but in reality nothing is ever written to the device (read-only mode?).

Now I'm going to try and recover it through serial port, which is located here:

Of course I'm gonna need usb to serial port adapter modified to 1,8v. I've found something like this:

and it says it supports 1,8v. Is it ok?

I would also like to know if it's possible to buy those molex connectors (like the one in the picture above). I've found them here http://pl.mouser.com/ProductDetail/M...WhsxkhIQ%3d%3d
but they charge 40E for shipping. Is there any way I can buy just 1 piece and not pay 99999x more for shipping?

Any other advice for my first attempt at serial port recovery?
