Downgrade Galaxy S6,S6 edge, S6 edge+ from Android 6.0.1 Marshmallow to 5.1.1 Lollipop, Yes You Can!

There has been a lot of questions via our contact page surrounding the Galaxy S6, S6 Edge, and even the Galaxy S6 Edge+ Android 6.0.1 Marshmallow updates. Some folks may not conveniently  satisfied how's the Marshmallow performed according to their own experienced. Some may complain about some lag issues, whilst others complained about some of their daily used or important   apps that may not tend to work any longer.

Majority of these folks were asking if they just can temporarily downgrade back their devices from Android 6.0.1 Marshmallow to Android 5.1.1 Lollipop just like the way it was before but may then get back to Marshmallow until it stabilized further.

You can do read these Marshmallow issues in forums and social media.   Now, to keep this post short and straight forward, "Can we really downgrade our Galaxy S6, S6 edge, and S6 edge+ from Android 6.0.1 Marshmallow back to Android 5.1.1 Lollipop?"
The Answer is; Yes you can!
This can only be done on international Galaxy S6, S6 edge, S6 Edge+ plus variants, including the American and Canadian version, but except to those device with built in "locked bootlooader" such as the Verizon and AT&T Galaxy S6, S6 edge and S6 Edge+ models. Devices with unlocked bootloaders can be freely downgrade-able, but those with highly secured bootloader cannot be messed around.

Please do note that this is only applicable for the first Android 6.0.1 Marshmallow update your device received.  This is not advisable to any newer OTA updates that may have a locked-up bootloader. 

Here are the list of Galaxy S6, S6 Edge, and S6 Edge+ with unlocked bootloaders and can be dowgraded from Android 6.0.1 Marshmallow back to Android 5.1.1 Lollipop.

Downgrade Galaxy S6 from Android 5.1.1 to 5.0.2, Don't Do it!

The Samsung Galaxy S6 and S6 Edge already got an update that brings the device OS to Android 5.1.1 Lollipop. Now most advanced users have had been asking if we can then be able to downgrade our owned Galaxy S6 or Galaxy S6 Edge running on Android 5.1.1 update and return it back to the old Android 5.0.2 firmware. The direct answer is No! Why is that and how come Samsung implemented that policy which some folks from Android community might disagree?

There are some good reason why some  folks prepared an Android smartphones instead of something else. One of these main reason is that they liked on tinkering and tweaking their devices. People that used to loved into rooting installing custom OS,  so they can install any 3rd party apps that requires a rooted device before it  can be actually installed. Whilst using a customized OS rectified the device the way how it look and feel according to the owners liking.

Recovery is not seandroid enforcing Galaxy S6 t-mobile g920t, how to fix

If you have just gotten into trouble such as "RECOVERY IS NOT SEANDROID ENFORCING" on your T-Mobile Galaxy S6  G920T, you are not alone. This dreaded error message appears if you have just like us who messed-up from rooting the Galaxy S6 right after updating to Android 5.1.1 update which will not tend to work at this moment.  The phone will just stuck on logo, with the error "RECOVERY IS NOT SEANDROID ENFORCING" instead, and will not boot up normally.  So just try this following solution, this might help you out to fix it and return back your phone to its normal booting sequence.

Solution 1: Set the Galaxy S6 into Download Mode

Right at the screen where it stuck in "RECOVERY IS NOT SEANDROID ENFORCING" and the Samsung Galaxy S6 logo press this 3-button combination Home,Volume Up and Power buttons. Once a warning messages showed that says press volume up to continue and press volume down to cancel, press the volume down button instead.  Wait until the phone reboots and see if it goes through the Samsung screen and booted further into the home screen. However, if it still stuck on the error screen proceed and try the second solution below.

Solution 2: Restore the Android 5.1.1 Update Firmware


If the phone continues stuck in "RECOVERY IS NOT SEANDROID ENFORCING" error screen, you may apply this solution. This will repair the Android 5.1.1 firmware that has been compromised from rooting. The Android OS "kernel" and "bootloader" might have slightly damaged or in mismatched staged causing the troubled error continues. So the only way to fix it is by reinstalling the original and official Android 5.1.1 firmware update.

This approach is technically what we've used to fully unroot the T-Mobile Galaxy S6 (SM-G920T).  It is the proven and very effective method and had been used even before the Galaxy S6 exist. Doing so will restore the entire Android 5.1.1 firmware build and wipes out any modification that has been made onto your Galaxy S6. So check it out and follow the step-by-step  guide below.

Step 1: Grab the necessary tools


Just make sure to grab the Android 5.1.1 stock firmware for Galaxy S6 SM-G920T. If you have the Galaxy S6 Edge SM-G925T that also showed the same trouble, you may also apply this solution but use the Galaxy S6 Edge SM-G925T stock firmware.

Grab the official Android 5.1.1 stock firmware through this pages
- Samsung Galaxy S6 Stock Firmware
- Samsung Galaxy S6 Edge Stock Firmware


Download tools:
- Odin3_v3.10.6 & Galaxy S6 USB driver

Step 2: Preparations

  • Extract or “unzip”  the firmware file after downloaded so that you’ll get the  "Odin flashable" tarball stock firmware  file.
  • Make sure the battery is re-charge or at-least still got 60% remaining power.
  • Activate the USB debugging mode in the device settings, from Home screen>>Settings>>Developer option, then mark check the box that says USB Debugging Mode.
  • Turn off the "Reactivation . Some other Galaxy S6 version this feature is pre-installed.  To turn it Off just go to Settings>>Security>>Reactivation Lock and then unmark check the Reactivation lock option. You may need to enter your password on this process.
  • Use the supplied USB data cable of your Galaxy S6.
  • Use Windows PC to this process as this will not work on MAC computers.

Step 3: The process


1. Run Odin on your PC desktop
2. Boot the Galaxy S6 into Odin download mode.
Turn it off, once completely shut down  hold down the ‘HOME’ + ‘VOLUME DOWN’ buttons and press the ‘POWER’ button for about 2 seconds until a WARNING! Screen appears. Press the ‘VOLUME UP’ button to continue or enter Download Mode.
3. Connect the phone to PC via USB. Then make sure you can see as phone “Added” in Odin log box or highlight the COM:ID once the device is detected,
4. In Odin window, Do Not ever tick ‘RE-Partition’ , just leave the ‘Auto Reboot’ and ‘F. Reset Time’ mark as checked.
5. Click on Odin’s AP button then browse and load the tarball file.
e.g. on T-Mobile Galaxy S6  SM-G920T:
G920TUVU2COF6_G920TTMB2COF6_G920TUVU2COF6_HOME.tar.md5″
6. Click on “Start” to flash the stock firmware
7. Wait until the flashing successfully finishes, you’ll just see a word ‘PASS’ in Odin. Once finish flashing, disconnect the phone from PC.

You may wait until the device completely reboots as the until in reaches in the home screen.

If ever my solution did not resolve the "RECOVERY IS NOT SEANDROID ENFORCING" on your T-Mobile Galaxy S6  G920T, I can only suggest you to visit your nearby service center. The folks out there can fix it for you.

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.
