“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.”

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.
