[Samsung Galaxy S7 Edge Guides, News, & Discussion] GearCEO:
Hi respected members, just want to share here, I recently flash Android 7.0 on my Samung S7 Edge since I wasn't on same region. So far I am enjoying Android 7.0 very much and still so far I am not having issue in any ways. For newbie, what I have done so far.

Only Flashing Android 7.0

1- Download Android 7.0 BTU from Official Site via Premium Membership since I have waiting.....

2- Donwload and open Odin v3.11.1 as Admin

3- Reboot Samsung S7 Edge in Download Mode by pressing and Hold Home + Power + Volume Down, once you reach the Download mode warning screen, press Volume Up to continue and connect with your PC/Laptop

4- Connect phone and wait until you get a blue sign in Odin

5- Select AP, BL, CP and CSC (Note Home_CSC) on desired slots

6- In Odin, I checked the following options

a- Auto-Reboot

b- Re-Partition (I read this on sammobile forum)

c- F. Reset Time

7- Click the start button, sit back and wait few minutes, it will reboot.

Note: This will wipe your Internal Memory for sure. Back up your data if you want through Tatinium or other such application

Since I was rooted on Marshmallow because I want to use Call Master which is necessary to my need so I planned to root my S7 edge on Android 7.0. I am now rooted without any issue (Big thanks to Chainfire and jcadduono) and running my all rooted apps as well. So what I have done so far for rooting.

If You Want To Root As Well

1- Go to Settings > About device. Tap 7 times on Build number to enable Developer options

2- Now go to Settings > Developer options. You need to enable OEM unlock, USB debugging

3- Donwload and run as Odin v3.11.1 as Admin

4- Download this file twrp-3.0.2-4-hero2lte.img.tar

5- Reboot Samsung S7 Edge in Download Mode by pressing and Hold Home + Power + Volume Down, once you reach the Download mode warning screen, press Volume Up to continue and connect with your PC/Laptop

6- Open Odin and place that twrp-3.0.2-4-hero2lte.img.tar file in the [AP] slot and disable Auto-Reboot, then press Start

7- Hold Volume Down + Home + Power to get out of Download mode and immediately swap to Volume Up when the screen blanks.

8- At this point, you will reach the screen asking you if you want to allow system modifications.

9- Now Wipe > Format Data > Type Yes. Once done then Press back button until you reach on Main Menu. Once reached then Press Reboot > Recovery

10- After rebooting, you will again reach TWRP Recovery. Now again swipe

11- Download no-verity-opt-encrypt-5.0.zip, however, the latest version is 5.1 but I used 5.0 because I was facing issues on 5.1 but you can still use 5.1 if you want. Now without exiting TWRP, transfer the no-verity-opt-encrypt-5.0.zip to your device over MTP (you need to stay connect with PC via cable) and flash it using Install in TWRP and reboot again into recovery mode

12- Download the latest SR3-SuperSU-v2.79-SR3-20170114223742.zip. Now without exiting TWRP, transfer the SR3-SuperSU-v2.79-SR3-20170114223742.zip to your device over MTP (you need to stay connect with PC via cable) and flash it using Install in TWRP and reboot again into recovery mode

Hope this helps

Regards
