Kindle Jailbreak

Special thanks to Serge A. Levin for updating my 3.2.1 jailbreak to remove the need for precise timing. It can now work as any other jailbreak. Just read and follow the directions in README.txt, or for your convenience:

1) Copy and paste the correct update for your device
k2 = Kindle 2 US
k2i = Kindle 2 International
dx = Kindle DX US
dxi = Kindle DX International
dxg = Kindle DX Graphite
k3 = Kindle 3 Wifi + 3G (US & Canada)
k3g = Kindle 3 Wifi + 3G (Elsewhere)
k3w = Kindle 3 Wifi
2) Go to the Settings page via Menu -> Settings
3) Select “Update Your Kindle”

This should in theory work with every Kindle version from 2.0 to 3.2.1. However, only Kindle 3 on 3.2.1 have been tested, so use at your own risk.

If this doesn’t work for your older version Kindle (< 3.2.1), try the 0.4 version which supports all Kindle 3.1 and below.

    So, whenever I try to update my kindle (kindle 3 wifi, 3.3 611680021), it says there was an error (Uoo4). Anything i can do to fix this? I have tried 10.n and this jailbreak and cannot seem to jailbreak it.

  2. Jason Dugham says:

    Note that the naming scheme on the jailbreak files is different for the 0.5.1.
    (from the readme)

    k2 = Kindle 2 US
    k2i = Kindle 2 International
    dx = Kindle DX US
    dxi = Kindle DX International
    dxg = Kindle DX Graphite
    k3g = Kindle 3 Wifi + 3G (US & Canada)
    k3gb = Kindle 3 Wifi + 3G (Elsewhere)
    k3w = Kindle 3 Wifi

  3. I’m having troubles trying to use your jailbreak (0.5.1) on a vanilla Kindle 2 US. I’m on version 2.5.8.

    After copying over update_jailbreak_0.5.1_k2_install.bin to the root folder, the option to “update your kindle” from Settings screen remains grayed out. I tried a force restart, and am getting a failure (error code 0003). It appears my Kindle is rejecting this file. Any ideas on what I can do to get it working?

  4. Mike Grainger says:

    Like Barry above, I have Kindle OS 3.3 on a Kindle Keyboard, 3g + wifi, and when I try either jailbreak, I get the U004 error code. Will there be an updated jailbreak for OS 3.3?

  5. Oleksiy says:

    Hi there! I tried to install 0.5.1 version on my Kindle 3 WiFi with 3.2.1 software, and the update successfuly installed, BUT – it didn’t make anything. Maybe I just don’t understand what for is this jailbreak, but I supposed that it has to remove all this special offers. And besides – is there any way to force Kindle to NOT change screensavers when sleeping? It just eats battery 🙁

  6. Pablo says:

    Is this jailbreak works for a kindle 3 that has 3.3 firmware version and it was never jailbreaked before?
    And how can I know if I have a

    k3g = Kindle 3 Wifi + 3G (US & Canada)

    k3gb = Kindle 3 Wifi + 3G (Elsewhere) ?

    Thanks in advance =)

  8. Marcos says:

    I cant jailbreak my KK3G US.
    On the first week I did the firmw. update to 3.3.
    I have read mobilereadforum and I could not change the screensaver follow the steps:
    – 0.10N 3G
    I could not change screens so…
    I used
    -0.10 3.2.1 3G + 0.25N
    still not changed.
    so can someone explain how to jailbreake and change 3.3?

  9. LuLu says:

    Just jb and installed latest ss update, first time, on K3gKbrd/US, ver 3.3. Went well. But old ss’s come up. Your you-can-delete-me ss is there. Have read for hours. So sorry – cannot find an answer. Thank you very much!

  10. LuLu says:

    Solved problem after many days. Downloads via Opera were problematic, at least on my computer. Uninstalled and reinstalled several times. Once I downloaded updates via Firefox, everything worked beautifully, the first time. Hopefully this will help someone who might encounter this strange circumstance.

  11. Mike says:


    Since jb’ing k3w with firmware 3.3 (B008) seems to cause trouble. Is there any chance we might jailbreak it at some point?

    Thanks for your work! Appreciated!

  12. darren born says:

  13. Les says:

    Did not work on my Kindle 3 Version 3.3.
    I did not do a factory reset as rather not, unless this is essential stage ?
    Please put a txt file with zip file to explain difference between k3 and k3i files. Tried both anyway

  14. tiny says:

    I’ve got the right file for my kindle 3 wifi, 3.3 611680021 (UK version) and every time I try to update I get the error code U004.
    What is this and how do I fix it?

  15. baash05 says:

    I’m right there with all the u004 codes. There does not seem to be anything I can do to get around it. As yet that is.

  16. Tiny says:

    Baash05, I downloaded and installed the 1.2.3 version after all the U004 codes and then it worked fine. Try that.

  17. Clincher says:

    BIIIIIG 10-4 on that Pullen – worked for me too! I have K3 3.3 US and I used ‘update_jailbreak_0.10.N_k3g-3.2.1_install.bin’ – no errors, successful updates – Bob’s your uncle (yes, I’m in the US). I have installed the SS update and it created the folders etc. The 3.2.1 update works for 3.3!!

  18. Rej says:

    I have a Kindle DX B005A and ver 2.5.8 and can’t seem to get the dxi file to install. I can update off kindle but mid update says error updating restarting then i don’t see any files in there nor anything changed. Anyone have any idea?

  19. Maarten says:

    Works-but causes freezes? (on my Kindle 2i)
    Wanted to include logfile- but can’t seem to find it (or references to it online- any help?)

    Thanks for the effort though! Awesome work!

  20. The Box Man says:

    Alright,so I tryed doing this and first, it didnt work. Then I did the ENABLE_DIAGS thing, and now I cant get out of diagnostics.I tryed pushing the Disable Diagnostics button,but it says “ not found.”Please help.

  21. The Box Man says:

    (btw) It actually said device_info.xml not found. Not sure if theres much of a difference, but anything to help. I have about 83 books on my Kindle and i want to read them. 😛

  22. Ariel says:

    I feel like a total loser for having to ask this, but how do you use this? “Copy and paste” isn’t enough info for me.

  23. Steve says:

    Thanks very much — the early version of jailbreak seemed to install successfully on my DXG with FW 2.5.8 loaded. However, there appears to be no change to the device. Can you tell me where I can access and change the screensaver images?

  24. I transfered update_jailbreak_0.5.1_dxi_install.bin to my international Kindle DX which has the latest 2.5.8 software update on it. NOTHING CHANGED on the device. I opened a PDF – I still cannot move the cursor within the document and I cannot highlight text.

    Should I download, transfer and update the latest software update from Amazon AFTER I run the jailbreak?


    Greetings from the University of Piraeus, Greece!

  25. UPDATE on my efforts to make this work: I have the white Kindle DX (international). I tried installing both versions 0.4 and 0.5.1 of the jailbreak and then tried to update to versions 3.1 and 3.3 of the Kindle DX for Europe. The BIN files are not recognized by Kindle, i.e. the update menu item is dimmed out.

    Hi mate:
    Its Maya from AU. I have got kindle dx version 2.5.8 (9.7″) and want to upgrade it to 3 or higher.
    I don’t have kindle 3rd generation so I don’t have host. Can you please send me (.bin) the output of the host?

    Your cooperation is fully appreciated and I am looking to hear from your regarding in this case.


  27. If anyone has a restore BIN file for a 2.5.8 US Kindle 2nd Generation, please contact me. I upgraded so many years ago that I have deleted the file long ago.

  28. I am a bit late to the party. Have anyone figured out a way to jail-brake kindle paperwhite 3 without touching the hardware? Please let me know if anyone knows how to do it.
