2. Solder Kindle serial pins
3. Use kermit, login as root, dd mmcblk0p[123] to /mnt/us
4. Reboot in recovery mode
5. Export FAT partition
6. Plug USB cable and backup mmcblk0p[123] to my PC

I'm going to copy official kindle update from amazon website and do:

U. Update using update*.bin file on FAT partition

Is that safe doing that? What else should I backup?
Ok so I'm a real noob! I've connected an FTDI USB-TTL 3v3 to the serial port. What baud rate, number of bits, parity, etc., should I be setting my terminal program to in order to communicate with the serial port of a PW1?
