These stock firmware cannot be used on other Galaxy S6 models as it may result into undesirable outcomes.

This is a very important part especially for beginners, that is because each specific Galaxy S6 models uses different firmware builds.

To do this just simply dial this code on the keypad *#12345# or by going to the Home > Apps > Settings > About Device> then look for the Model number along with general system information of your phone.
