This Guide is one i wrote in a reply on another forum, I thought more people would see it if i posted it here as well. As usual, if you brick your phone while following this guide, it is your problem, and i take no repsonsibility for any bricked S7 Actives due to this guide. Its not likely, but in the event that it occurs, understand that it's your problem.
There is no s7 active oreo rom in ODIN flashable format available yet, but you can update by flashing nougat, and flashing two ota flashable zip files in stock recovery. If you go to this website, and click the blue download button, you can extract the downloaded file with 7zip, or winrar, and flash the md5 files in ODIN, and you will then be on stock android nougat. You can then copy this zip file to your phone's external micro sd card, without extracting it, and use stock recovery mode (turn off, then volume up + home + power) to "apply update from sd card", or if you don't have a micro sd card, click "apply update from adb" and look up "how to use adb sideload" on google. Once it's done updating, do the same thing with this zip file, using stock recovery and "apply update from sd card" or using "apply update from ADB", and you will be on android 8.0 oreo. you can always use the first file you downloaded to go back to stock nougat if you don't like oreo, but it's working great for me! Enjoy android Oreo on your S7 Active, hopefully we will see a root soon, as the nougat root just bricks my phone while it is on oreo. I do not recommend using a newer oreo OTA zip instead of the one i posted, as some of the other ones flash a newer bootloader, thus preventing a downgrade back to nougat in the event something catastrophic happens.
