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

[Biberkopf]

Hi there,
I've uploaded the jaibreak on my kindle and then the python, but it didn't create the linkss folder, only a file called linkjail. What's wrong ?
Thanks for your help !

jailbreak is not the same as screensavers hack. You also need to install the screensavers hack.

[Biberkopf]

Thanks qlob.
I did so and now I'm a step further but not done yet, because I have a white screen as a screensaver. Can it be because the last book that I opened is a mobi and this feature would only works with azw books (which I don't have) ?

***EDIT*** Forget this message, now it works perfectly. I don't know why it needed 5 minutes or so for the screensaver to appear, but ok, it's there.

@Biberkopf: Yep, K2/3/DX + framework start == 100% CPU for a while (depending on the size of the library), and since we need a good chunk of CPU time ourselves to process the image, and we're doing that at a very low priority, it can take a while for non-cached stuff .

I need some help to install usbnet.
I tried to install the binary and it failed, I went further more and did the following:
I converted the bin file to update_usbnetwork_0.46.N_dxg_install.bin.tgz file using the kindletool.
extracted that file to a direcory on my computer
placed the file usbnet.tar.gz from the inside the root directory of the kindle using the usb cable
created a directory customupdates
placed the file install.sh from the package into that directory.
Disconnected the usb.
used the launchpad command Shift Shift I to run the file install.sh
after I rebooted I found the usbnet directory under the root, looked inside and found the usbnetwork_install.log.
The message inside is

usbnetwork v0.46.N, Sat Jul 30 19:54:28 CDT 2011
ln: /usr/sbin/dropbearmulti: Read-only file system

So I guess the installation was unsuccessful.
Any ideas what is going on?

So, still not sure of how to fix a 'corrupt userstore' - any tips? My Kindle is still out of action - not totally bricked, but not far off (it's unusable). Do I have to do a debricking, or can I fix just the userstore?

[NiLuJe]

@blaser: Don't try to be 'cute' with an update package unless you know what you're doing. (And, no, it's not packaged to work as an lp package, so, yeah, it doesn't work, nothing strange there...).

Read the first post & usbnet's doc again. (And, FWIW, when you mention an 'error', it actually helps if you actually give us a bit more details about it ^^).

Wild guess: you were rebooting instead of using the UYK link.

@Tanga: IIRC, that was just a wild guess. Can't really diagnose this kind of issue by remote mind read . Do a bit of digging, check the logs, try to pinpoint what/when happens, etc.

Hi. does it just sort of lock up. and not respond to button presses. or load for a second then crash horribly.

Sent mine back, although it had cracks in the casing that were not my doing so yeah... they took it back for that - very decently. but it also had that issue. Never got to the bottom of it. Just FYI. although how much info there actually is there is... well ... limited.

I classed it as "Terminal"

Doh,

Sadly it's been more than a year since I bought my Kindle. Any other options?

[YukonTrooper]

I was just wondering: would it be possible to integrate the additional line-spacing options and fourth font option from Kindle Collections into a hack? I think those would be logical inclusions.

If you use linux, a simple mkfs.vfat while it was plugged in worked nicely for me...
But mine, interestingly enough, stopped crashing long enough for me to fix it from a raspberry pi I had handy...
Or you could try getting a script to run on kindle bootup somehow to erase the userstore, but then you would lose all of your books, hacks, etc (or leave them in an unstable state)...
Do you have myts installed? if you create an ENABLE_DIAGS file in / (yes, it works from the rootfs as well) and then use diags to export the userstore long enough to try and fix it...
Lots of complicated suggestions, sorry....

EDIT: If worse comes to worse, you could try and figure out a way to wipe the userstore with AT or k3flasher, but the above warning about erasing the uerstore applies.

If you look inside my port I quoted the error
"ln: /usr/sbin/dropbearmulti: Read-only file system"

I'm not an expert in Kindle, just bought one recently but I have a lot of experience with Linux.

I read the install.sh and figured out what it is doing and I tried to do things manually.
I guess it tries to create a hard link on a ro file system and it fails.
I do not know much about the Kindle OS.

@blaser: I recommend following what NiLuJe said earlier and just do it like everyone else.

drop the bin on the root of the usb drive, use the update your kindle link in settings.

That's what I did initially and it failed.
I placed the bin file on the root directory through the usb and used the UYK link, it failed.
Got stuck for a long time and at the end I received an error message that the update failed.

Can you remember what error number it was? U00something?
