Problem Solved, thank you NiLuJe !
I am sorry if the question has alredy been discussed, but i was unable to find something closely related to my problem.
A year ago I purchased a Kindle 4 NT, then put screensavers of my own using usb net and these lines in putty :
(coming from here http://hackaday.com/2012/01/05/custo...ouch-kindle-4/
mount /dev/mmcblk0p1 /mnt/base-mmc
mv /mnt/base-mmc/opt/amazon/screen_saver/600x800 /mnt/base-mmc/opt/amazon/screen_saver/600x800.old
ln -sfn /mnt/us/screensaver /mnt/base-mmc/opt/amazon/screen_saver/600x800
everything went fine, until a week ago, when i wanted to update my kindle,
I got error code U006.
So i tried this to put back everything as normal : (step provided in the commentary section of the previous page)
Just reverted my 4.0.1 hack back to normal to install 4.1.0!
It took a while (mainly due to my absent-minded decision to
delete the .old file that backs it up) but this is what I did:
1. The password here worked for me: http://members.ping.de/~sven/kindle.html#
I typed in my serial code sans spaces and it worked first time.
2. If you still have the .old folder, do the
mv /mnt/base-mmc/opt/amazon/screen_saver/600×800.old /mnt/base-mmc/opt/amazon/screen_saver/600×800 command.
Make sure to take care when copying and pasting commands,
as my putty client replaces Xs with ?s.
3. If you don’t, you can find all the old screensavers here:
DO NOT RENAME THE IMAGES.
Their names are exactly how the kindle likes them.
Put them all into a folder on your kindle root.
4. Do a ls /mnt/base-mmc/opt/amazon/screen_saver/ command
to see what files are there.
If you have 800×600 and adunits, that’s fine.
If your 800×600 file has vanished (like mine!) do a mkdir /mnt/base-mmc/opt/amazon/screen_saver/600×800 command to make it.
Fill this folder with the images in step 3, by doing cp -r /mnt/us/>>FILENAME<>IMAGENAME<< /mnt/base-mmc/opt/amazon/screen_saver/600×800 for each image.
When I did the move command for a folder,
it just slapped the folder into the destination folder, which is no use.
If you know a better way, use it!
Basically, the ideal solution is to have ls /mnt/base-mmc/opt/amazon/screen_saver/ report back '800×600' and 'adunits',
and ls /mnt/base-mmc/opt/amazon/screen_saver/800×600
to report back all the files from the link above with their correct names.
If any directories exist which are weird, use rm -r -f <> to get rid of them.
Once I had it set up as such, trying an update worked! :)
My problem is after following these steps, i still had the same problem, and i had a blank screensaver on top of that...
I then tried the same technique to re-enable screensaver, but it is the same problem...
I was hopping for some of you to have ideas or instructions for me to follow and get this little kindle back to normal.
Is there a way to fully restore it, as if it were out of factory ?
by debricking it ?
thank you for your attention
and good reading !
