Kindle 2.5.2 software upgrade

June 11, 2010

The rollout of the 2.5 software update for the Kindle has not been’s proudest moment of customer service.

Perhaps they were wise to not release the 2.5 update en masse over the Whispernet service–as evident by the already updated version of 2.5.2. But they should have made the 2.5, or at least the new 2.5.2, available for download via the website (like previous firmware updates) for those both anxious to try out the new features and/or (in the case of the 2.5 firmware) willing to suffer through a few bugs.

Well, the 2.5.2 firmware has managed to find its way to the internet thanks to some Kindle owners who copied the file before the upgrade process began.

Note: This update DOES WORK (I have installed this file on my Kindle 2 International), but this particular update is only for Kindle 2 International versions and you must have 2.3.4 firmware currently installed.  If you currently have version 2.3.3, install the 2.3.4 bin file first.

[To check your current firmware version, from the home screen click “MENU” -> “Settings” and then look at the bottom right-hand corner of your screen]

Instructions for upgrading to 2.5.2

  1. If you currently have firmware version 2.3.4, skip to Step 4.  If your current version is 2.3.3 download the 2.3.4 firmware update (59KB) here.
  2. Connect your Kindle to your computer via the USB cable and copy the file, “Update_kindle2_gw_2.3.4.bin” to root directory of the Kindle (note: do NOT place it in the folders, “audible”, “documents” or “music”).
  3. Unplug the Kindle. From the Kindle’s home screen, click “MENU” -> “Settings” -> “MENU” -> “Update Your Kindle” and follow the instructions
  4. Download the 2.5.2 firmware update (13.2MB) here.
  5. Connect your Kindle to your computer via the USB cable and copy the file, “Update_kindle2_gw_2.5.2.bin” to root directory of the Kindle (note: do NOT place it in the folders, “audible”, “documents” or “music”).
  6. Unplug the Kindle. From the Kindle’s home screen, click “MENU” -> “Settings” -> “MENU” -> “Update Your Kindle” and follow the instructions

You now have the the latest software for your Kindle.  A summary of the improvements:

  • Collections: Organize your books and documents into one or more collections (instructions).
  • PDF Pan and Zoom: Zoom into PDFs and pan around to easily view small print and detailed tables or graphics (instructions).
  • Password Protection: Password protect your Kindle when you’re not using it (instructions).

    My Kindle 2 (international) has always show v2.3 for software. I am assuming this means I need to install the 2.3.4 upgrade first, correct? I was always wondering why my unit only shows 2.3 when others mention 2.3.3 or 2.3.4…

    I’ve downloaded both files (THANKS!) and am emailing to home for me to try there… I have my Kindle at work but not the cable! :( Should be fun to play with this weekend. Glad I just checked my Google Reader and saw your article!!

    Have a great weekend and keep the good news rolling for us Kindle lovers!

    Bummer! Couldn’t get it to work no matter what with my Kindle 2 (International) that I bought in early March. I tried to copy first just onto the Kindle and not into any of the folders the 2.3.4 and followed instructions… then tried in the system folder and but no matter what cannot get the “update” button to be functional – still grayed out. I tried with 2.5.2 instead, both ways again (once just into the Kindle folder – not any sub-folder – but it discards those and then in System folder… no luck).

    Any advice?

      You need to first upgrade to 2.3.3. Then 2.3.4 and finally, 2.5.2

      Get the 2.3.3 firmware here.

      Let me know, but this should solve your problem (as well as anyone else who currently has 2.3 version)

    I had the same problem.


    First update your Kindle Version 2.3 to 2.3.3 then to 2.3.4 and at last to 2.5.2

    Use the following bin files for the international Kindle2 (Serial-No. starts with B003):

    I hope this will help you out.

      Thanks for the help. If I’ve already installed 2.5, how do I go back and install them sequentially? I transferred the 2.3.3 file to my kindle, but the ‘update’ option is still greyed out.

    Does this work on a K2US?

    It worked!!! Thanks for your help. I’m intending on posting up the three files as well and spreading the word for others and pointing them to this post. It’s great to see the “power of community” at work on the ‘net… after 29 years online, community still bowls me over regularly. :)

    Hm, I was able to update straight to 2.5.2 from 2.3.3. Hopefully I didn’t screw anything up. Seems to be working great.

    Hi – first of all, thanks to flatland for providing this information.

    I am currently in the process of upgrading, but I had a problem going from 2.3.3 to 2.3.4, and I wanted to mention it here in case someone else has the same problem. My “Update your kindle” button wasn’t grayed out, but it also didn’t accomplish anything – just a flash, and I was back at the settings screen looking at version 2.3.3. I finally solved this by doing a restart from the settings menu and then going through the update process. Worked like a charm. Will now attempt the biggie to 2.5.2. Wish me luck :-)

    Question: My Kindle says it is operating on 2.5.6 upgrade. Someone told me that his friend’s Kindle had page numbers instead of locations at the bottom of the page. I still have locations; page numbers would be far easier to deal with. What is the advantage of
    “locations” anyway?
