How to Unbrick Your Amazon Kindle Fire

    In many cases, a failed installation of a custom ROM often results in a soft-bricked device. With so many tutorials promising safe procedures for upgrading your device, there’s some chance that you could end up scratching your head thinking about what could possibly have gone wrong.

    With over a million devices already sold, the Amazon Kindle Fire is certainly the best Android tablet around town. Featuring a decent dual-core 1 GHz processor and an entertaining 7-inch IPS display, the Kindle Fire is no ordinary device to mess around with.  Flashing custom ROMs and over-the-air (OTA) updates are just some of the few reasons that could likely brick your precious device during a failed attempt.

    Owners of the Amazon Kindle Fire who have soft-bricked their devices will finally be able to unbrick their tablets and bring it back to life. Thanks to the application known as the Kindle Fire Unbrick Utility developed by the guys at XDA-Developers, you can now resurrect your Kindle Fire to full gear.

    The application is easy to use and can be applied to your tablet, regardless of the firmware that it is running. The best thing about this tool is that it generally addresses the most common causes of your device’s malfunction.

    From failed modding of framework–res.apk to pesky recovery boot loops, the Kindle Fire Unbrick Utility generally covers everything. Think of it as an all-in-one Kindle Fire solution for your soft-bricked devices.  With the simple to use interface, it is perfectly safe and easy to follow.


    • Amazon Kindle Fire
    • Computer running Windows
    • Java installed on the Windows machine (Get Java here)
    • Kindle Fire Unbrick Utility (download here)
    • Ensure that your device has at least 60% of power left so that it doesn’t get turned off once the unbricking process starts.


    1. Extract the contents of the Kindle Fire Unbrick Utility to your computer.
    2. Open a command prompt and change directory to where you extracted the Kindle Fire Unbrick Utility files.
    3. Run KindleUnbrickV1.0.jar (it’s a Java JAR file).  You can run the JAR file by executing “java -jar KindleUnbrickV1.0.jar” (without the quotes).
    4. Connect your Kindle Fire to your computer using a USB cable.
    5. From here, you’ll then be able to choose from 5 different options with their corresponding number of choice. The options are:
      1. Recovery Loop
      2. Stuck at logo
      3. Framework-Res
      4. Modded /system/app
      5. Other…
    6. Click the appropriate option that best describes the current condition of your Kindle Fire.
    7. Depending on the choice you made, the recovery process will roughly take 10 minutes to finish restoring your device to normal state. Your device will automatically reboot itself after the recovery process.
    8. If your device continuously reboots itself after the recovery process, repeat the procedure to unbrick your device.

    Congratulations! You have successfully unbricked your Amazon Kindle Fire with the Kindle Fire Unbrick Utility. You can now use your device again.

        @guest: you may want to try to run the file as Administrator in windows. Not sure how the Windows java application is coded, but if it uses ADB then you will want to be running it with administrator privileges.

    • trent

      it is stuck at logo but that selection isnt working, actually none of them recover it. it reboots and back to the logo. It isnt mounted, it shows up as removable disk H:

    • Cameron LaPage

      How do I do number 2?

    • Cameron LaPage

      None of these unbrick methods work! Why, because it can’t find my device, and it can’t find my device because it won’t register that it’s plugged in until you unlock it, and you can’t unlock it unless it boots! And what’s my problem? It won’t boot!

        Hi Cameron, come on over to and we can help you. We have a free tool at the bottom of our site called Restore2Stock that should work for you. If you are having driver issues we can help there too.

        • Cameron LaPage

          Thanks but somehow my kindle started working again yesterday. I’m not sure how.

          • n2aos

            great, glad to hear it. :)

            • Cameron LaPage

              I don’t have TWRP anyway but thanks. However I may take a look at the software once I get back home. It looks really cool.

            • Cameron LaPage

              I mean this rooting method looks more trustworthy. Especially after what happened with Kindle Fire Utility

    • n2aos
