Font, ScreenSaver & USBNetwork Hacks for Kindle 2.x, 3.x & 4.x

[Aweberman]

I'm trying to get the screen saver hack working on my Kindle 3 (keyboard, wi-fi, firmware 3.4.2). Here's what I've done so far:

- Installed and successfully (I think) updated the device using this file:

Update_jailbreak_0.13.N_k3w_install.bin

- Unsuccessfully updated the screen saver update using this file:

Update_ss_0.47.N_k2_dx_k3_install.bin

I have been able to successfully select "Update your Kindle" from the Menu within Settings (i.e., it has not been greyed out), but when actually processing the update, I receive the screen that tells me "The update was not successful. Your Kindle is restarting..." There is a code that reads U002 in the lower lefthand corner. (I ejected the device and unplugged it from the computer before attempting the update.)

I attempted the process a second time after the device finished restarting. Then, following a suggestion from earlier in this thread, I rebooted the device myself, then attempted the screen saver update for a third time; still no dice.

Any suggestions would be appreciated, since I'm tired of seeing Mark Twain's mug (and that definition of "kindle").

@Aweberman: The snapshot packages are only installable through MRPI. Use the latest releases from this very thread if you can't/won't use MRPI .

Success!

I installed MKK, then KUAL, then MRPI, then the screen saver hack, and it is working. It was more steps than I realized, but it wasn't hard.

Thanks!

Often seen on the 'net are rating systems in terms of from one to five starts . . . . (hold that thought)

Perhaps there is a way that these add-ins could be rated (one to five) on their approach to Instant Gratification.
I.E: IG
There are now several generations that will have things no other way.

Though I feel like I have the hacks up and running correctly (as noted two posts up), I'm still not getting the current cover to appear as the screen saver. I have rebooted several times, even following this exchange from a few months back:

But I want to show me the cover of the last book I opened.

I tried 2 things:
1. creating the "cover" file in "linkss" folder (didnt work)
2. via KUAL
2.1 open Helper+
2.2 Select "ALLOW ScreenSaver" (a check mark is showed)
2.3 Head to "Screen Saver" Menu
2.4 select "COVER MODE BEHAVIOR" and select "White Borders"

<snip>

...but all I continue to see is the "hasn't yet successfully processed a book cover" splash screen.

@Aweberman: You need to install Python for cover mode to work.

(And you need to restart the framework/device for it to the when toggling cover mode).

Ah yes. In my list above of the things I've already installed, I neglected to include Python--but that is also installed. I have also rebooted it a number of times, including once from within KUAL, through the "Screen Savers > Restart framework now" option.

Just now I enabled the "verbose mode" option, restarted the framework, and opened a book, which prompted this message: "S W failed to process cover."

What size is the book?
What format?

Also make sure the date/time is sane on your device.

I saw that in one of the instruction posts (or maybe in the read me file) and confirmed that on the initial install ... though I don't see a place to set the date, only the time.

The size of the current book I'm reading is 4.2 megabytes. It was obtained through Amazon's Kindle store.

The other books I tried were mostly purchased from Amazon, though not quite so large. One of them was an older book in PRC format (1.1 MB).

Edit: I have also tried dropping an image (downloaded from a Reddit thread on the topic) into the "linkss/screensavers" folder on the Kindle, as the first post in this thread directs. After a reboot, this is also not showing up when I put the device to sleep; in fact, the "currently in 'cover' mode" message is still there.

I feel quite certain I'm missing something obvious here, but after reading through the instructions multiple times, I'm at a loss as to what that might be.

@Aweberman: Completely normal that the usual cycle of images won't show up in cover mode, they're mutually exclusive .

As for what's wrong with cover mode, guess the only way left to figure things out is for you to send me some system logs .
Soon after a book switch, enter ;dm in the Homescreen's searchbar, and PM me the "all_system_logs" file that'll dump in documents/ .

Hello,

I installed the screensavers hack on my Kindle 4NT yesterday and wanted to try the cover mode. However, it did not work so I enabled verbose mode and every time I open a book i get the error Message "S W failed to process cover".

My ebooks are almost exclusively .mobi format without drm converted and managed with calibre with the exception of dictionaries and a single book from amazons lending library. But all of them fail with the error message.

random screensaver mode actually works just fine, it's just the cover mode that fails. I entered ;dm in the search bar, can I PM the all_system_logs file to you, NiLuJe?

EDIT: Forget all of the above, I was missing python. It works now.

Hi,

I would appreciate your help with my Kindle 2 International D00701.
I recently updated to version 2.5.8 to be able to use the 3G.
Now I try to jailbreak it, but I keep receiving the message "Update was not successful..."
Do you know if there is a way to jailbreak it and apply the font hack under firmware 2.5.8?
Or could I roll the firmware back to a version that is supported by the jailbreak and the font hack?

I will be grateful for any advice!

Thanks!

[knc1]

The jail break is compatible.

You most likely have an earlier jb that you need to uninstall first.
or
You had Doukan installed at some time in the past.
