Hi,

i have a Kindle 4 NT jailbroken with the "Ixtab Simple JailBreak Method" but now where can i find the right "update package" ?

...i already tried the "Screesaver hack" ( wiki tutorial ) and it didn't work!


PS: in the K4 Wiki it says: "Update: So far this current screensaver hack is not working on the Kindle NT or the Kindle NT SO!!!! " Is there a way o can jailbreak my kindle 4 NT (4.1.0fw) ?




@geekmaster: no, my kindle is not a SO (79$) Version

Ok. Good. I do not have time to research this now (or for the next few weeks). I am hoping somebody familiar with the 4.1.0 screensaver changes will help you here.

meeh, ok. Thanks

Anyone?

I'm afraid, there is no "Update package".
If you want to have custom screensavers, you have to do it manually.

There are manuals, how to do that.
For example:

You just have to SSH into the kindle (e.g. with the USBnet-methode) and then create a RUNME.sh in the /mnt/us with the following content:

mntroot rw
if [ ! -f /var/local/adunits.bkp ]; then
	mv /var/local/adunits /var/local/adunits.bkp
	touch /var/local/adunits
fi
mntroot ro

Save, exit and make the following:

chmod +x /mnt/us/RUNME.sh; mntroot rw

Make a backup about the mntus.params file with this:

cp /var/local/system/mntus.params /var/local/system/mntus.params.BKP

Extend the original mntus.params with the followings:

if [ -e /mnt/us/RUNME.sh ]; then
	sh /mnt/us/RUNME.sh
fi

If you would like to see a log then change the "sh /mnt/us/RUNME.sh" with "sh /mnt/us/RUNME.sh > /mnt/us/RUNME.log"

If you are ready, just create and link the screensaver folder, just like before:

mkdir /mnt/us/screensaver
mount /dev/mmcblk0p1 /mnt/base-mmc
mv /mnt/base-mmc/opt/amazon/screen_saver/600x800 /mnt/base-mmc/opt/amazon/screen_saver/600x800.bkp
ln -sfn /mnt/us/screensaver /mnt/base-mmc/opt/amazon/screen_saver/600x800
exit

As far as I know this is the only black/hackway and there's no "block the ads" and "put screensavers" hack.
I tried it on my own K4 NT SO, works.

FYI, Mobileread disapproves of and does not condone circumventing the display of advertisements in advertisement-subsidized devices.

The ads can be removed without violating the Amazon TOS by going to the Manage your Kindle page at Amazon and shelling out the difference between the cost of the SO version and the ad-free version.

[Gondolkodo]

It's true, and I know it, but if you read the title of this thread, it's about how to hack it.
And I tried it, works, I had set it back.

P.S.: I understand you, I have modified the original text. Sorry for my uncorrect composition.

[WT Sharpe]

No problem. Thanks for the edit.

[hostar]

Gondolkodo: but mog has Kindle without ads and there is no
/var/local/adunits I think.

But the rest is right :-)
I just think users should learn to read and search existing answers than copy it over and over to more threads.

[Gondolkodo]

I know only this thing and may it help, test it and let us know if it's not a working way.

Or just copy a pointer to it onto the appropriate Wiki index page.

Anyone can edit the Wiki page, no registration or login required, just be able to prove you are a human when saving the edit.

You are right, it's there, I haven't seen this before...

As I understand this, the moderators prefer that we not discuss HOW TO cheat amazon by violating our Terms of Service agreement, but the site owner's policy is that existing posts are not illegal and can stay here. That makes it kind of a "gray area" to be discussed carefully.

Although some of us (including myself) strongly defended amazon as the "good guys" in the past, recent experiences with amazon have made us (as discussed in PMs and in some posts) a lot less willing to defend amazon after all the hostile updates that break custom apps in 5.1.0 and 4.1.0 firmware. Also, amazon has fallen through on things they promised me verbally, by NOT calling me back or emailing me with details as they said, on multiple occasions.

If somebody has technical questions, I will continue to try to answer them, and I will try to keep my opinion about amazon out of it. If these requests stray into ad removal, I may help up to a point, but in general I will leave that up to others because it does not interest me, and I do not like getting warnings from site moderators for my posts.

[geekmaster]

I sure hope that amazon comes out with more "developer friendly" firmware in the future so that we will be a lot less tempted to help people remove their ads (one of the most requested kindle hacks at mobileread -- extremely popular despite the occasional moderator warning)... You cannot legislate morality, as they say...

And if you are logged in (using the MR wiki registration), you do not even have to prove that you are human. I have mine set to autologin.
