Tools Software Jailbreak for PW2, PW3, PW3W, KT2, KV, KOA and KT3

[Valladao]

Hi, Phung.

I'm only an user like yourself, but here's something you might try (since KUAL seems to be working for you).
Go to this thread https://www.mobileread.com/forums/sh...d.php?t=203326 and get the "Helper" extension. Once you place the "helper" folder inside the "extensions" one inside your Kindle, disconnect it and enter KUAL. There should be a "Helper" tab there, click that and then click "PREVENT ScreenSaver". That should do the trick (but don't forget to click the "ALLOW..." one once you're finished your reading).

About the files meant for KOReader only opening through KUAL, have you installed KPVBooklet? Maybe you should try to reinstall it if you already did. Here's a link: https://github.com/koreader/kpvbooklet/releases
This one should be installed with KUAL or the ;log mrpi command, by the way, since it's not a KUAL extension.

Hi Valladao, It works now. Thanks alot for your help.

Do you know how to transfer files into Kindle via a wifi connection? I am using Send-To-Kindle app now, but this method can only apply for some types of files. For example, Send-To-Kindle doesn't send DJVU files. Calibre wireless connection seems to be a candidate, but I cannot get it working now.

You're welcome, Phung. Glad I could help

About your other question, I'm sorry but I only know Send to Kindle myself.

If you have USBnetwork installed, you can use SCP

However, if I reset (i.e. restart, do not mean reset to the factory) my Kindle, then Kual and Koreader work again.

This seems to be normal in such cases. I can reproduce the very same behaviour after any firmware update and the necessarily following reinstallation of my hacks. E.g. Vlasovsoft's tools and KOReader only work flawlessly thru KUAL if I restarted the Kindle once after finishing the reinstallation of the KUAL booklet via MRPI.

Interestingly, the document version of Vlasovsoft's CoolReader works even without such an additional restart and even before the MRPI procedure, i.e. right after the firmware update and the following automatic first restart. I use it as a first simple test whether the jb did actually survive or not.

Completely normal and well documented over the years.
Changing registration state also wipes the product keys (those part of the "hotfix" not the jb key).
Re-start (re-boot) automatically runs the 'survival code' to auto-reinstall them.
You should have had an on-screen message, but you might not have been watching for it.

Hi all,

If I buy a new Kindle with installed a new an old software that allows me to jailbreak it, do I need to register the kindle the first time via wifi? If this is a mandatory step, how I can avoid that it automatically updates to the latest software version?

I do not not want buy a new kindle and have it updated prior that I did all steps for the jailbreak.

Many thanks in advance

Well, a very intresting piece of information, and completely new to me, that (parts of?) the hotfix/jb survival code are performed after any reboot. (The latter is the much better wording instead of "restart" which could easily be confused with the never ever "reset (to factory defaults)" function, though this unfortunately is Amazon's wording...)

I'm normally very carefully watching my devices even if "simply" rebooting them. I've never seen such additional " **** BRIDGE+ **** " etc. messages from the jb hotfix code when doing this. Only, of course, after all and any firmware updates (but these are no "normal reboots" in my understanding). And I certainly remember also not to have seen this message popping up shortly when doing the above mentioned manual (second) reboot after a preceding fw update, and I, in the next step, re-applied all my hacks via MRPI to get them finally running as intended.

Now I'm really wondering why the "factory reset" is such a problem? Okay, it clears the user space completely - but if you first make a complete copy of all (including even the hidden "system") directories, and of course including /mkk (this is where the "user visible" part of the hotfix resides), /extensions, etc.: Why isn't it possible after an accidentally performed "reset to factory defaults", to just restore the complete backup of the user space now, then perform a local reboot to reapply all user keys via the (now again present) hotfix code - and everything is fine again?!?

Well, the step by step manual in post #1 recommends to firstly register a Kindle "out of the box" with an Amazon account, before doing a jb.

I've experiences with 4 different current 7th and 8th generation models (my two mentioned left, and a KV and KOA respectively of two friends of mine, whom I helped with the a bit tricky procedure, because they are no computer nerds ). And I've none of these registered with Amazon before.

Step by step:
a) Get them out of the box.
b) Make a first function test, i.e. set language but skip the Wifi settings (so the device was never ever connected to whatever internet server).
c) Just to make sure: "reset to factory defaults" (may even be skipped)
d) as b)
e) Perform the jailbreak as described here.

Never have had any problems with preinstalled firmwares 5.7.x and especially 5.8.x ...

BTW: It's also safe to shortly connect a factory-new Kindle to the internet. This e.g. synchronizes the clock. And could also begin with the download of the unwanted fw update. But this takes some minutes. And even if the complete file is on your Kindle - don't panic: When connecting via USB, you'll find it there and simply delete it. Just make sure not to perform a local reboot - then the auto-update could start and you're lost with the software jb...

Yeah I read the introduction part where it says to register the kindle and this is reason of my question.

However, you are saying that the registration it is not needed, so which of the two is correct? jailbreak w/o fist registration or jailbreak after registration? are there any differences between the two methods?

BTW, the software version is 5.8.2.1.

Thank you!

[Antinoos]

Well, partially the description is too detailed, OTOH there is missing some background info. Like in this case. As I've unterstood, there are certain, older fw versions where are some menu entries missing when not registered first. No idea which... The only one you really need is "Update your Kindle" - and this was always accessible right "out of the box".

The proof of the pudding is to eat it. I.e. just try it out if you are able to do the initial version downgrade. Finally you end up with a relatively new fw version (like 5.8.7), and then it's still time to register your device with Amazon if really needed...

Also keep in mind that Antinoos is writing about his experience with the German firmware builds, which are known to have differences from the generic.

@knc1

Thanks for highlighting this, I was not aware.

And so what do you recommend, register the kindle prior to apply the jailbreak or go ahead w/o having it registered?

Thank you

Try it.

Having it registered or not registered will not change the chances of being able to recover from a failure state.

But keep in mind, every change to the registration state causes the application key store to be wiped.
So why wipe something you just went to a lot of trouble to install, only to have to re-install stuff?

Get the registration state set to suit your needs, then do the jailbreak procedure followed by leaving the registration state alone.

Note:
In many of the Amazon firmware versions, registering the device is also your agreement to the EULA they want you to agree to.
Not everyone finds that a suitable state of affairs - requiring the agreement to the EULA just to use features the device was advertised as offering the purchaser.



Hmm...
I wonder what the FTC has to say about that.
None of the Amazon advertising has qualifiactions or disclaimers on the feature descriptions such as: "only available to registered devices".

Maybe after I finish: with my auto insurance company, I will try: that for awhile.

@knc1
I am not sure to fully understand the part in bold.

In case I have not been clear in my previous posts of today, please let me remark that I am talking about a new kindle so never registered.

I just hope that the registration will be completed in less time than the update of the firmware, I have a little of fear that somenthing may go wrong....
