Galaxy S6, The operating system on your device has been modified in anunauthorized way, how to fix?

“The operating system on your device has been modified in an unauthorised way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.”

If you ever receive that error message when installing a new software update on your Galaxy S6 and Galaxy S6 Edge, don't get annoyed.  It may unpleasant to those who don't  have any idea of what was that error says all about. It only appears if the software update find something like 'unofficial OS and other system images' was installed in your device. It's either your Galaxy S6 was rooted, and installed with custom OS.


The update won't just let you through to install it, but it just simply warns you that your device has been modified and that where it says  “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.”

It's precautionary measures from Samsung side. because if someone do install the official software update on-top of a modified and unofficial one will result into a serious problem. It could harm your Galaxy S6 or S6 Edge in no time.  So the best way to prevent that before it happens on all rooted and modified Galaxy S6 and S6 Edge, is by not letting anyone else to install the update.  Samsung and your carrier provider won't support your device anymore but instead they are pointing out to resolve the issue by using Smart Switch.

Smart Switch is a software application owned and developed by Samsung itself.  The basic functionality of this application is to transfer, backup and restore data files on newer Android device. But it has also a capability to initialize and restore the Galaxy S6 and S6 Edge official "Android OS" firmware.

Okay I got it? Where I can download the Smart Switch? 
You can grab Samsung Smart Switch at Samsung website itself, here you go -

Just make sure to download the Smart Switch that is built for PC and Mac computers, depends of what you have then grab the right one. But before using Smart Switch, let me ask you first; Are you sure that your Galaxy S6 was rooted and or modified by you personally? If yes, then you didn't got surprise though. Download it at once, then proceed to the step-by step guide below.  But if  ever you did not do anything nor touched you phone's Android OS such as rooting, installing a custom recovery to a modified firmware then continue reading.

If you  do not have any idea and did know what kind of unauthorized way was it, and why was that dreadful error message have showed-up for some reason. Then there is one way to find it out, by checking the binary status within the device itself.  This will allow you to confirm if your precious Galaxy S5 and S6 Edge was has been modified or not.

To check and confirm it,  just reboot your Galaxy S6 into download mode.  First,  turn off the phone, then press and hold, Home, Volume down and Power keys at the same time. And you may then press the Volume up key as it ask you to continue.

Deactivate Download mode:
Press and hold Volume buttons (Up & down) , Home and Power keys at the same time for couple of seconds then released at once.

Now, once your Galaxy S6 sets in download mode screen,  it;s now time to check the binary status.  This photo below is my untouched Galaxy S6 Edge. it has never been rooted nor modified whatsoever.  So therefore, updating to a newer software update via Over-The-Air  (OTA) is easy and smooth without any hiccups.
You may noticed these lines where it says:
Current BINARY: Samsung official
System Status: Official

That is the only one thing emphasized that the device is running on official firmware and the software update can get through without that annoying warning message.,  “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.” keep on appearing.
Now,  if you have something similar to that operating system status but yet receive the warning message.  You may now consider that it might be caused by a third-party apps you have previously installed on your Galaxy S6 or either you have some files stored in your SD card causing the false flag to appear.



Alternatively, do try these things first  before performing a software update again;

1.  Try to uninstall some apps that you think that it could be the primary culprit of the warning message.

2. Try to perform factory data reset, in recovery mode. But first, make sure to make a full back-up of your stored data and files before doing so as it will delete all the files you have stored in the phone's memory storage.

To access the recovery mode, simply turn off the phone, then press and hold down Volume Up, Home and Power button simultaneously.
Once the Galaxy S6 is sets in  recovery mode screen, simply select to perform these following  task:
  • Wipe data/factory reset
  • Wipe cache partition

3. You may also remove the SD card from the device, then run and perform the software update again.

If it gets through, then it's a success story and your journey ends here. But if not read-on to the next procedure using Smart Switch as what the warning message appeared pointed out to do so.

Unroot Samsung Galaxy S6 and restore back to official stock firmware using Smart Switch (First Method)


Using Samsung’s owned app called “Smart Switch” that allows Galaxy S6 users to back up and transfer files but it also capable for restoring the Galaxy S6 official firmware. The Smart Switch is the replacement of Samsung’s “Kies” that can be use on Galaxy S6 and latest Samsung Android devices. We are going to use the Smart switch apps that can be installed on both Windows and Mac computers. Though this method will work to unroot the Samsung Galaxy S6 but sometimes it will fail as depends how your Galaxy S6 being modified. But you may try this method first, unless we still have a the second method down below.

Download Smart Switch


Run Smart Switch as administrator once installed in your computer . Then simply connect your Galaxy S6. Click “Backup” icon to back up your important data first and foremost such as Contacts, Messages, Call Log, Videos, Music, Photos, Application and etc.

Then wait until it says Software update and Initialization are complete.


Once your Galaxy S6 reboots disconnect and disconnect the USB data cable. Then lastly restore the previously back-up files by clicking the “Restore” icon.

However, if the Smart Switch method fail, you may try to use the advanced users approach to unroot Galaxy S6 manually.  The process is something similar to the above equation but it will forcefully install back the Galaxy S6 stock firmware.

How to Update a Rooted Galaxy S6 & S6 Edge using Smart Switch

If you have a rooted Galaxy S6 chances is that you won't be able to get the latest OTA update. Instead you might only received this error messages that says like;
“The operating system on your device has been modified in an unauthorised way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.”

A rooted Galaxy S6 and S6 Edge is  technically cannot get and will no longer receive an official support from Samsung itself. However, what Samsung does is to notify the Galaxy S6 users that the device has been modified and advises anyone to try to perform a software update using Smart Switch within a PC.

So, if ever you'll get the error message and wasn't been able to install the latest update, all you need is Download the Smart Switch. Simply install it into your computer  and try to perform an update manually. Just make sure that you Galaxy S6 still have at-least 40% of the battery's remaining power.

How to Install a Software Update on a Rooted Galaxy S6 and S6 Edge


  1. Launch Smart Switch in your computer.
  2. Connect your Galaxy S6 into your computer via USB data cable.
  3. Click Backup icon to back up your important data first and foremost such as Contacts, Messages, Call Log, Videos, Music, Photos, Application and other stuff.
  4. Click on More..., then  choose Emergency software recovery and initialization.
  5. Select “Software Update and  Initialization” tab.

The whole process will run and depends to how large the firmware update file is, so you must wait until it says "Software update and Initialization are complete". Once finishes, just restore the previously backup data from your computer into your Galaxy S6.

However, if the above solution did not went smoothly, there is another approach form where you can directly install back the new firmware, either by unrooting your Galaxy S6 manually, or by visiting your nearest Samsung service centers, as they will update your device beforehand.

How to Update the Samsung Galaxy S6 Edge SM-G925F to Official Android 5.0.2 Lollipop


Samsung was urge us to follow some important steps before performing the software update.  I also added some useful insights and why you should follow this procedures to safely kept your Galaxy S6 Edge in a much safer way while performing software update.

First and foremost make sure to recharge your Galaxy S6 Edge – While performing software update on Galaxy S6 Edge it may only takes just a couple of minutes but sometimes it may take longer. It will depend on how small or large the update size is, but most cases it also affects the speed of your data connection. Slower WiFi data connection may take longer while a stronger data connection is more speedy. A 40% to 50% recharged battery is enough but a fully recharged is way much better. Since we cannot determine how what the exact time we need to consume when initiating the firmware update so we should make sure our device has still enough battery remaining power to avoid any fatal issues. Have you ever heard or encountered those fellas who ended their devices into soft-bricks? A device was just stuck on Samsung logo or welcome screen and can’t reboot normally, those are what we called soft-bricks. And most probably caused by an inadequate battery power while performing the software update.

Do not forget to back up all of the important data – Even though there are no any data that are going to be deleted right after performing software update. But what if the software update went wrong, the update unexpectedly fails and then the phone becomes unresponsive and then it forces you to perform a wipe data/factory that basically wipes your phone’s memory storage just to resolve the issue. So you should backup your important files, including contacts, messages, call log, photos, videos, music, and apps. You cannot recover these files if somehow accidentally deleted when the software update goes wrong.

Your Galaxy S6 Edge must still runs on the official software version and hasn’t been rooted nor installed with non-official firmware update – Just in-case you just need to know that a rooted and a modified Galaxy S6 Edge will not get official software update anymore from Samsung and either to which carrier providers it came from. It will not allow users to install the update as it might harm the device once the update has made. So a rooted and modified Galaxy S6 Edge usually receives this warning message instead, that says: ‘The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.‘.

This is the usual method on how to check and to perform an update on S6 Edge to the latest software version.  This method is what we called Firmware Update  Over-The-Air and so-called as FOTA or simply OTA update. In most often cases a notification message will directly sent to you by your network provider and by Samsung itself, telling you that there is a new update that has now available for download.  This approach requires you to prepare a strong WiFi connection,  and so it might happened sometimes that one did not receive any software update notification messages; 1) if and when the device is out of range during the software update roll out  period, 2) Automatic update has been turned off in the device Settings.
However, We can still manually check for the update instead.
Here’s how to do it manually:
  • In your Galaxy S6 Edge Home screen tap on Apps.
  • Select the Settings gear icon.
  • Tap About device.
  • Tap Software update.
  • Tap Check for update.

It will then notify you that a new update is available for download. But it also says that “Your device software is up to date“, and there is no software update is yet available for grab. You can simply choose Download and Install now if you do so or else Install later if you want to get the update in later time.

But if ever you might have had receive this message while checking software update that says something like “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.”  This is a warning message that only appears for those devices that has been rooted and installed with modified and unofficial firmware.  So to be able to get the Software OTA update again, you must Unroot your Galaxy S6 Edge first and removed any modification that has been installed on it.

It will then automatically tells you that a new update is available or your software is up to date when there is none yet.

It's a maintenance update that occasionally includes stability improvements, bug fixes, enhancements and further improvements to performance. The OE2 update will specifically targets and are about to resolve the dropped calls problem which has been reported by some users and has been found on previous version (G920PVPU1AOCF), according to Sprint. Some users are experiencing both dropped calls and have had said that their Galaxy S6 will only perfectly works when the network mode is set to "CDMA only". But once the device network mode is set to "CDMA/LTE or Automatic", then a high rate of dropped calls persist. The update will technically boost the LTE connectivity, to which dropped calls/no service, can't send or receive texts and poor data speeds arises when its signal strength is basically poor.
