Update: Fix for Random reboot is to use the latest Eng Bootloader V6. The two year old Samsung Galaxy S7 and S7 Edge and all of their variants have already been updated to Android 8.0 Oreo by the end of last month. This first began when the Exynos variants of S7 G930F/FD (Global) and S7 Edge G935F/FD received the Oreo OTA update. Later, the US carriers rolled out similar update for AT&T, T-Mobile, Verizon, Sprint, etc. Now, here is a tutorial on how to root Snapdragon S7 and S7 Edge for latest Samsung Experience 9.0 based on Android 8.0 Oreo.
We already have the rooting tutorial for Exynos S7 and S7 Edge. This is possible because the Global variants have a readily Unlockable Bootloader. The Qualcomm Snapdragon processors, on the other hand, do not have this privilege. Thanks to developer, jrkruse, for deploying an Engineering Bootloader from Nougat that can be used on Oreo firmware as well. So the following procedure works on Android 7.0 Nougat as well as Android 8.0 Oreo firmware to gain root access for all US carrier models like SM-G930A/P/T/V and SM-G935A/P/T/V.
Root Snapdragon S7/S7 Edge supported devices:
- AT&T Galaxy S7 (Edge) SM-G930A or G935A (Oreo/Nougat)
- Sprint Galaxy S7 (Edge) SM-G930P or G935P (Oreo/Nougat)
- Verizon Galaxy S7 (Edge) SM-G930V or G935V (Oreo/Nougat)
- T-Mobile S7 (Edge) SM-G930T or G935T (Oreo/Nougat)
Warning: Although, the procedure has been tested working on some Snapdragon S7 devices, it doesn’t mean it will work for all the devices. If something goes wrong, we won’t be responsible. It is wise to backup and keep a full stock firmware file handy so your Samsung Galaxy device can be restored to stock via Odin. Reader’s discretion is advised.

Possible fix for heating and lag after rooting Galaxy S7
Install Kernel Adiutor (ROOT) app from the Play store and grant root access. Open app and set both CPU governors to ONDEMAND and set apply on boot. Also, CONSERVATIVE kernel settings could give better battery life. Keep testing the options for your device.

Download and flash the S7_Oreo_Su_Binary_Only_ADB_Root.zip. This root zip is only for Android 8.0 Oreo firmware on Galaxy S7 devices. It only installs the SU binary to the
system/xbin folder to root Android devices. It does not disable DM-verity and system file encryption. There is no SuperSU app either. Install this SuperSU.apk.
