Loving this site and the wealth of info available, hoping it will help me beat the big corporate...

After a very rude and unhelpful conversation with Amazon, I'm going to attempt to unbrick my Kindle Paperwhite 2 (2013) Wifi 4Gb model myself. It's borked after a firmware update.

After reading the site a lot, I tried to buy one of the recommended Jim.sh USB boards but Amazon won't deliver to Australia. I found a video showing how to turn a 3.3v/5v board into a 1.8v board here.

So I have purchased a 3.3v/5v USB to serial board with FTDI232 chip and ordered a 1.8v LDO (awaiting delivery). I have also purchased a 10W soldering iron, solder, helping hands with magnifier.

Then I found this thread, with the solder free method which looks much more appealing as I have never soldered such a tiny connection before.

Couple of questions from a noob...on the TTL-232RG-VREG1V8-WE cable which I plan to buy from here what is the preferred way to connect the bare wires to the wire with the crocodile clip on it in the photos here? Could you show a pic of the whole cable pls? I assume I could use any method to connect these, like a connector block or bullet joints like a car radio uses maybe?

One other question...if I use the usb to serial board i bought, do the RX and TX pins have a voltage on them? Do they also need to be set to 1.8v?
