Tutorial FW >= 5.11 Factory JailBreak (i.e., KT4)

[Sargeywah]

Howdy.

any help would be greatly appreciated.
I have been unable to jailbreak my paperwhite Kt4 (white model).

I downloaded all the correct files and yet i am still unable to jailbreak.

I copied the update_kt4_5.11.0_factory.bin over, when unplugged it says an invalid update has been added and then deletes the file.

The hot fix was able to install via UYK no issues.

Serial G090 WH05 **** 07H3
FW 5.11.2 (3541880032)

I dont see what is going wrong.
Anything would be a huge help

(Hint: it involves a numerical comparison and the big fat warning about those in the matching Open Sesame sticky).

Hello,

I just got a new Paperwhite 3 (WiFi + 3g US Serial Number G090 G205 ...) and immediately put it into airplane mode and placed the update.bin.tmp.partial folder on the device.

Unfortunately, it is already on 5.11.2 and said invalid update and deleted the .bin file when I began following the rest of the steps to jailbreak.

This whole idea of jailbreaking Kindles is awesome, and I'd love to do it someday. Keep up the good work!

Hello all,
Just attempted to Jailbreak my Paperwhite tonight running FW 5.8.9.2 (3179290002)
Grabbed the images from the Snapshot post, extracted kindle-jb-factory-1.3-r16160.tar.xz -> kindle-jb-factory-1.3-r16160.tar -> kindle-jb-factory-1.3-r16160

Placed main-htmlviewer.tar.gz on the highest directory when plugging via USB into my Win7 machine.

Ran the search (;installHtml, hit return)
Nothing happened. waited a few minutes, repeated.
Power cycled the device and it looked like it ran through some sort of update on boot, but still no change, don't see any document saying "You are Jailbroken"

Any ideas? Did I miss a step somewhere?

Should I have updated to FW 5.9.6.1 (MD5: a5460e698a531c7770ba2b1ac31667b0) First?

@Woh: You *have to* be running the factory image, yes.

Just to understand clearly before I proceed then, I should upgrade to the official
PW3: 5.9.6.1 and then re-do the jailbreaking process I described in my post?

Are you following the steps in the thread below?

https://www.mobileread.com/forums/sh...d.php?t=313086

PW3 running less than or equal to 5.9.6.1 are a special case that thread documents, so the instructions are much simpler because there are much fewer decisions to make going from step to step.

I was not actually, I was following the instructions I found here:
Tutorial Open Sesame! (AKA., The New & Improved JailBreak Index)
and
Snapshots of NiLuJe's hacks

I'll take a look through this other thread now, but so what would be the best method currently for jailbreaking my device with it's current firmware ?
currently FW 5.8.9.2 (3179290002)

So according to this information on the wiki:

If the third field of your firmware version number: 5.8.7.0.1 is larger than 7 this jail break will not work on your device.
That means it will not work on: 5.8.8, 5.8.9, 5.8.10, ..., 5.8.99999999. (It's NOT possible at this time to downgrade and use this jailbreak)
Of course, this also means that it will not work on anything newer than the 5.8.x branch itself (i.e., 5.9.x, and whatever might come next ).
Please do not even think of asking if this message still means what is written. The message is kept current.

Correct now or not?
or just this just mean that one should update to FW 5.9.6.1 before moving ahead with the jailbreak method?

You missed this part of the wiki.

There is a special case for the PW3 running 5.9.6.1 firmware or earlier. Please see this thread for instructions.

Open Sesame are the generic instructions. You'll note it mentions that you need to install factory firmware first before you can jailbreak.

These instructions are specific for PW3 with FW <= 5.9.6.1. Just use the latest versions of the files from snapshots.

Iirc, 5.8.9.2 is weird (UPDATE ERROR: 16 when installing factory fw directly). So for this, you'll need to install customer 5.9.6.1 then factory 5.9.6.1 before running factory jailbreak.

P.S. I've just edited the wiki to make the special cases for PW3 and PW4 more prominent.

So yes it is possible to go from 5.8.9.2 > customer 5.9.6.1 > factory 5.9.6.1 > open sesame generic instructions ( factory jailbreak ) ?

A definitive 'yes or no' would be immensely more helpful than the last three answers I've received.

I did exactly what was described above and it's jailbroken and functional now. Hope this can help someone else.

Not sure if it is the right place to post, but since KT4 is benign mentioned in the title, I assume we can discuss KT3 too.

I have G000 K905 Kindle Basic 2 (2016) KT3 FW 5.10.2, any way to jailbreak it?

[hius07]

KT3 can be jailbroken on custom firmwares 5.8.7.0.1 and lower or any factory firmwares.
So if you have not updated the firmware - yes, you can install the initial factory firmware 5.8.0 and apply jb on it.
