And to think I used to think those were safer/easier.

This is one of the best mate. great dev, great support, great.. well you get the idea. Safe hands.

@kasumi: Yup, this is OTA safe .

*rant*
Unlike, indeed, the few crappy commands laying around the internet (I purged the Wiki, we should be safe on MR ^^). Which provided me with a fun evening of entertainment today, after trying to jailbreak a K4... Utter madness & destruction ensued, apparently simply because of these stupid workarounds...
*/rant*

Anyway, that helped fix the K4 JailBreak doc, and find a bunch of stupid mistakes in USBNet (like, didn't anybody notice that scp was broken? Since apparently forever, and I never noticed because both my K2 and K3 had an old symlink laying around... >_<").

[NiLuJe]

Released USBNetwork v0.45.N

* Always enable USE_VOLUMD on the K4 (@ install time)
* Add a symlink for scp, because I somehow managed to remove it at one point, and without it, we can't use scp .

It sometimes helps to actually have applicable hardware, so you can actually test your hacks.

[NiLuJe]

@GM: Yep, apparently, it really does ;D.

And... I think I actually never did setup the scp symlink properly in usbnet... The one on my K2 is vintage: Aug 28 2009. >_<". It might actually be part of the vanilla system, which might explain why I never questioned it...

I'm never trusting anymore of those "You can *DO THIS* without Jailbreaking" hacks. The public should be educated more about how dangerous those stuff actually are. You should know something is wrong when you go like this:

Jailbreaking: Hey that was EASY!
Installing USBnet: Phtttt I can do that.
Hack away in SSH: What does this mean?? Error? Um okay, let me try this.....uh-oh

@NiLuJe:

Anyways...geekmaster told me to reinstall my jailbreak, but I never gave any details so I suppose I could ask again, if you would so please answer me. This is what I did:

• Installed kindle-jailbreak-k4-1.4.N.zip. Success.
• Installed kindle-usbnetwork-0.44.N.zip. Success.
• Bricked.
• Factory reset with /usr/sbin/factory_reset. Debricked.
• Only default files left in USB mass storage

So now I want to install the new kindle-jailbreak-k4-1.5.N.zip.
Do I have to uninstall kindle-jailbreak-k4-1.4.N.zip and usbnetwork first? Or just go ahead?

Thanks

I think you are supposed to still use the uninstallers, since the factory reset does not remove the hacks.

[NiLuJe]

@kasumi:

If you only did a factory reset, and didn't flash anything, you should only need to put the usbnet folder back in the userstore, the JB & usbnet hack are still 'installed', only the stuff in the userstore is gone.

But, given the fact that it's a K4, and I just fixed a few things in the K4 install process, I'd recommend just running the latest usbnet *installer* .

(No need to uninstall anything to upgrade the stuff in this thread, not even the JB on this device).

Hi, I have the 0.11.N for the k3gb installed but want to uninstall it to be ble to use duokan but in the zip file there is no uninstall bin file for this version. What can I do?

[kasumi]

qlob, NiLuJe:

You guys rock!

[NiLuJe]

@hamburghammer: Ha. Nice catch, I screwed the filenames up.

EDIT: Just re-uploaded a package with proper filenames.

The system logs might hold more information, but then again, maybe not...

@simblanco: Don't reboot with a custom .bin on your Kindle. Always use the 'Update Your Kindle' link from the Settings' page menu.

Ah, well thanks for the info. It still is working, so no complaints on my side. I just noticed the updates to these hacks on here since my last visit to this forum, so I guess we'll see if all goes well again when I update those.

I know this isn't a big deal, but I've noticed that the Picture Fullscreen hack isn't on the whitelist on the latest Jailbreak hack. It's not a huge issue, but I figured I'd mention it. I always just manually add it by doing the following: add line "update_picture-fullscreen" into file linkjail/etc/whitelist.

Thanks a lot, will check later.

[NiLuJe]

@inameiname: The latest jailbreak doesn't rely on the whitelist anymore. It's just there as a potential fallback (and for the update traps of the ss/fonts hacks).

But, for completeness' sake could you link me to the hack you mentioned?
