It has to be up-to-date and no system root or unlock should have happened, if the same happened needs to be revoked.

Generally you would get notification for any eligible update but just in case you haven’t rooted your mobile and up-to-date firmware is there means no need to wipe your eyes or bang your head somewhere. Sometimes you could be able to do this OTA update in force mode. For this please refer the below mentioned method.

3. Update via Odin: ( Unofficial way to flash official firmware):

This method is more preferred among the users for several reason. First of all, it allow you to update your device to latest firmware even if Samsung officially don’t rolled out a firmware for your country or if your device yet to receive your country specific firmware. The very next important reason is, it allow you to install latest firmware even if you rooted your device, have custom ROM installed or if you have play with the system some way or another. Another good thing about this Odin update is, if your device running on an official firmware then flashing using this method won’t erase your Galaxy S7 Edge internal memory data. Another possible reason to use this method probably is, you can use this Odin flash method to downgrade your existing firmware if you really need to. This method won’t increase binary counter as well as Knox hence you shouldn’t worry about warranty.

  1. Connect your device with PC using a USB cable. Make sure, you have already enabled developer mode on your smartphone navigate towards “menu –> settings –> about phone” and tap several times (total 7 times) on Built Number until you become a developer;
  2. Now from “menu –> settings –> developer options” enable the USB Debugging option.
  3. Download and install ODIN in your PC and as well as install Galaxy S7 Edge USB drivers.
  4. Now download the required software update from True Android dedicated Samsung Firmware section or Samsung official website and store it in the PC.

  6. Make sure the device is connected with the PC and added message should come up in the ODIN software in your PC. If not unplug the USB cable and reinstall the drivers and try again; you can also try switching USB port. Its always better idea to use USB cable that comes with your Galaxy S7 Edge for this purpose.
  7. Once you did the changes in your phone it should enter into the download mode. Tap on PA option from the Odin and select the required firmware update from your PC (if you downloaded zip file then extract it to get tar file, Odin only accept .tar files).
  8. In Odin window, make sure only Auto Reboot and F. Reset Time checkboxes are selected.

  10. Once flashing completed, your Galaxy S7 Edge will restart and soon you will see a PASS message with green background in the left-most box at the very top of the Odin. You can now unplug the USB cable to disconnect your device from computer.

4. Custom ROM update (unofficial way to update):

It is always a good practice for manufacturer to keep some of the potential of a phone hidden or locked. Since that might cause the stability issues or for some other reason the manufacturers keep them hidden. Also manufacturer always like to have you restricted and force you to use their bloatware or services. However, developer are always there to help you out from this. That’s why they develop various custom ROM to rescue you. There are basically two type of custom ROM – one is based on official firmware and other is based on Google repository or based on another custom ROM. Custom ROM that based on official firmware mostly Odin flashable hence you can follow method 3 tutorial for this. Another type of custom ROM can only be flashed with the help of custom recovery such as CWM recovery or TWRP recovery. Please note, since this method increase binary counter as well as Knox counter (few official firmware based custom ROM may not increase it) you void the manufacturer warranty by following this method. A custom ROM is not always stable so you can expect irregularities with this update. Hence it is good to execute a backup process such as Nandroid which would save your complete android present version so that you can use it later in case you need it back. Now lets see how to update custom ROM in your device.

  1. Download the custom ROM file in the computer from the third part developer website (you can always search True Android to see if anything available).
