SOLVED! Kindle Fire ADB Status Offline Troubleshooting

It’s not uncommon for people to come across the ADB status offline error while rooting their Kindle Fire which gives rise to discussions about Kindle Fire ADB status offline troubleshooting. For most of the time, the use of obsolete SDK is the trigger so the best solution is to update the SDK. Also, you could restart the device then see how things tune out. Spare a bit of your time to check out this article and learn what must be done to root your Kindle Fire successfully. 

Causes Of The Error 


For your information, quite a few factors affect the rooting process and the SDK (Software Development Kit) is one of them. Starting from version 4.2.2, there is a security feature that requires you to confirm the RSA fingerprint on the connecting device. If you use an out-of-date SDK as you root your Kindle Fire, it’s only natural that you would run into the ADB status offline error. On the bright side, if the SDK is the root of the problem, there is no need to do much.


It’s possible to connect to ADB via Wi-Fi but wireless connection could result in errors at times. Thus, once it comes to Kindle Fire ADB status offline troubleshooting, Wi-Fi is one of the suspects. 

What Must Be Done

Update SDK 

Option 1

The SDK Manager is located in Android Studio under the Tools menu and you could tell whether there is a pending update via the download icon in the left column. To update a package, all you have to do is to check the checkbox next to it. To apply the updates, select Apply, choose OK and follow license agreements. The updated packages should be saved in the directory known as the Android SDK Location.  

Option 2

  • Step 1: Download the latest command-line tools package from the Android Studio downloads page. After the download finishes, extract the package.
  • Step 2: Create a new directory for the Android SDK (for instance, android_sdk) then put the extracted cmdline-tools into it. That is going to be your Android SDK directory from now on.
  • Step 3: Enter the extracted cmdline-tools directory and create a subdirectory called ‘latest’.
  • Step 4: Move the original cmdline-tools directory contents, including the ‘lib’ directory, ‘bin’ directory, ‘NOTICE.txt’ file, and file, into the ‘latest’ directory.
  • Step 5: Use the command-line tools to update SDK. 

Restart Kindle File 

  • Step 1: Sever USB connection and turn off the device’s Wi-Fi.
  • Step 2: Close all Integrated Development Environments (IDEs) such as Android Studio, Eclipse, etc. 
  • Step 3: Run the ‘adb kill-server’ command to ensure that ADB (Android Debug Bridge) is not running.
  • Step 4: Restart Kindle Fire.
  • Step 5: Connect the device via USB connection then run the ‘adb devices’ command. That should start the ADB daemon and your device should be online again.

What Does It Mean When The Device Is Listed As Offline When Using ADB??

Can I Use ADB Over Wi-Fi Instead Of a USB Connection?

Using ADB over a Wi-Fi connection instead of a USB is possible. To do so, you need to enable ADB debugging on the device, connect the device and computer to the same Wi-Fi network then use the ‘adb connect’ command to establish a connection. Remember that using ADB over Wi-Fi may be slower and less stable than using a USB connection.

Which One Is Superior, Kindle Or Tablet?

It depends on what you’re looking for in a device. In most of the cases, Kindle devices are specifically designed for reading ebooks while tablets can be used for all sorts of tasks including browsing the web, streaming videos, playing games, … If your main goal is to read ebooks, a Kindle might be a better choice for you.
