I am very glad to report that I got one DXG demo unit flashed to 3.2.1

1) get the right usb2ttl
I tried 5v, 3v, 3v + res. + diode. Eventually ordered 1.8v and it works like charm
2) copy rootfs.img to kindle
3) solder connection to serial interface
3) login as root from putty, dd to overwrite /dev/mmcblk0p1
This step took hours and I got tons of "Buffer I/O error". Eventually I decide to give up, force kindle reboot.
But then it come back with 3.2.1 running fine.

The mp3 of 3.2.1 is really bad. I need DXG 2.5.8 image to downgrade it. If anyone can help, please pm me.

Thanks to stangri, knc1, Begemot, geekmaster, twobob, megacoupe, dpavlin and ofcourse yifanlu.

You guys rock!
