HISTORY :-)
- new Kindle K4NT
- with ugly sreensaver's pictures
- screensaver hack:

mntroot -rw
cd /mnt/us
mkdir /mnt/us/screensaver
chmod 777 screensaver
mount /dev/mmcblk0p1 /mnt/base-mmc
mv /mnt/base-mmc/opt/amazon/screen_saver/600x800 /mnt/base-mmc/opt/amazon/screen_saver/600x800_
ln -sfn /mnt/us/screensaver /mnt/base-mmc/opt/amazon/screen_saver/600x800
exit

FINE...

later...
- firmware update 4.1.0 exist
- why not, update...
uups, error U006 !?

study this forum -> unbrick your kindle is solution...

1. download images from http://gitbrew.org/~dasmoover/kindle/k4/forensic/
2. download all necessary tools by "A small debricking guide for “noobs”"
https://www.mobileread.com/forums/sho...d.php?t=180789
3. start procedure - fastboot:

4. next step - putty:

[root@[192_168_15_244] root]# reboot

now...
Kindle don't reboot, is frozen. Still diags screens and no reaction for keys...
Only possible works is press the combination of magic button and power button and start procedure again - with same result (5 times)

any suggestion for me?
I promise - no more hacks of my Kindle

Thanks for your help...
