How to Solve Device Has Been Modified Error Message in Android


A few days ago, Android 4.3 firmware for the Note 2 was already available to some regions like India and China. And after having heard of the news, I attempt to update my phone via WiFi. To my surprise a message “Your device has been modified. Software updates are not available” pops up. I didn’t know what to do at first. I got nervous because this might void the warranty of my Note 2. The only thing that I can remember is that I root my phone using SuperSU. So I quickly unroot it first by choosing ‘full unroot’ in the options provided and then I fire up my browser and Google  for the answer.

Luckily I found several solutions. Some them were related to rooting their phone, some were not. There are many options out there that you can choose from but I think there’s only one solution to this problem. The solution I’m referring to is the method suggested by ‘vferrari’ of So in this post I will tell you how I solved this problem using that same method as suggested by ‘vferrari’. But before we proceed, I think we need to make it clear that the method to put your Android (Samsung) phone into recovery mode or download mode is not the same. Also, you need to press the right button in the right sequence so that you will not end up restarting your phone over and over again.

Android Recovery Mode Screen

This is what the screen will look like in Recovery Mode.

To begin with, when we say ‘Recovery Mode’ you need to press the ‘Volume Up’ and ‘Menu’ button simultaneously. Keep pressing the two button then press the ‘Power’ button last until your phone’s screen lights up. If it did light up, that is the time that you move away your finger from the Volume and Power button or you might end up messing up your phone.

On the other hand, putting your phone to ‘Download Mode’ means doing almost the same thing when you put your phone to ‘Recovery Mode’ but this time you press the ‘Volume Down’ button instead.

If you reached this paragraph by skipping the contents above, I will assume that you already knew what you’re doing with your phone. Also, I will assume that you already understand that I (or anyone) will not be held responsible in case your phone got messed up. So if you’re ready then try following the steps below to solve the “Your device has been modified” problem.

  1. If you have an SD card installed, unmount it first.
  2. Shutdown your Android device.
  3. Put your phone into ‘Recovery Mode’.
  4. Using the ‘Volume Down’ button, select the ‘wipe cache partition’ option by pressing the ‘Power’ button. Wait for the process to complete.
  5. Using the ‘Volume Up’ button, select the ‘reboot system’ now then press the ‘Power’ button to reboot your phone.

If you follow the steps above correctly, I assume that the problem is now gone. You can now try updating again your Android via WiFi (OTA) and see if the error message will appear. If you have further questions please leave a comment below or start a new topic in the forum. Have a nice day!

    Also using SuperSU? I think you need to unroot it using this app. Then uninstall this app.

    Perhaps you should try uninstalling the apps that you use to root your device. And also before doing that, you should remove those apps that you give root access.

    Just unroot it first and restart your phone? What I mean is that revoke the permission given to your apps then uninstall the root app then try the steps above. I hope this helps.
