I've bought a PW demo unit from eBay with a hope that I can get it working as normal device.
Basically, what I have done so far:
1. Buy a FTDI Breakout USB-TTL (~$8)
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?
