Please read the safety guidelines on how to use a stock firmware: How to Install the Galaxy S6 Stock Firmware

These firmware packages can only be used exclusively on Galaxy S6 SM-G920A only, the AT&T variant. These stock firmware cannot be used on other Galaxy S6 models as it may result into undesirable outcomes. You might check and confirm which version of Galaxy S6 you have according to its model number. 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.
