[Samsung Galaxy S7 Edge Questions and Answers] kanesglove:
It's pretty disappointing that nobody ever responded to this considering how big is a community it is and how popular the S7 Edge was. I know this is pretty old and hopefully you were able to resolve this before this message but I'm going to respond to this just so you don't feel like your question wasn't acknowledged at all. I have an S7 Edge through Verizon which uses the Snapdragon processor. And I will find a link to post for you that although the method says it's discontinued I rooted my phone through this method and it works fine. The only reason that you would have to wipe your phone is if you're changing firmware as far as I know. I've rooted my phones and did not have to wipe them. I kept all the data and everything.

Before I lift this you are also asking about an application that you could use to back up your phone and that would be Samsung smart switch. It has a companion app for the desktop and it sinks to the phone and it'll make a backup of your data.

Now on to the root method all props and praise goes to the people that worked to give this to the people I'm not good at doing all this **** and I'm not meaning to step on any toes I'm just trying to help you since nobody did for two ****ing years.

BELOW IS THE ROOT AND MOD FOR THE PHONE!!!!!

Follow this method to root:

1. Shut off the phone and boot into download mode (volume down, home, and power). Use Odin And Flash Nougat_S7_Edge_EngBoot.tar.md5 In AP Slot

2. When the phone reboots, unlock developer options by going into the phone settings scroll down to 'about phone' find the build number and tap on it repeatedly after several times it will unlock Developer Options then back out once and in your settings you should have a new option on the very bottom called developer options go into that and enable USB debugging and Disable Verify Apps Over USB.

Plug the phone into the computer and make sure you have adb and fastboot installed to this location

C:\Users\YOUR PROFILE\AppData\Local\Android\Sdk\platform-tools

go to that folder and inside it hold shift and right click then click on 'open command window here'

ODIN FAILED TO WRITE ERROR

Did you get this Failed To Write Message in Odin?

----------------------------

Odin Error Message:

<ID:0/003> FAIL! Model dismatch fail

<OSM> All threads completed. (succeed 0 / failed 1)

SOLUTIONS

Did you:

? Open Odin as Administrator?

? Try the Prince Comsy version?

? Enable Developer Settings?

-Open Settings > About Phone > Tap Build Number 7 Times

? Enable OEM Unlock?

-Go Back to Settings > Tap Developer Options > Tap OEM Unlock

? Enable USB Debugging?

-Tap Developer Options > Tap USB Debugging

NOTHING WORKS

Did you try every single thing but nothing works?

Well, did you right click "Odin" each time you go to open it and then click "open as administrator"?

Sometimes you have to try several different versions of Odin.

But I have found that Odin3 v3.12.7 was the one that would work when the others had not.

I always would forget to also open Odin as Administrator.

It's a pain in the neck to have to remember to open as admin every time.

But you usually have to do it.

Did you check that ADB had started? Maybe that might be the reason it won't work?

But I doubt it! But you just never know and I am just trying to help you get it flashed.

It's a very quick flash and you can see that the PDA load was very quick as well.

But as far as the errors, you just have to keep trying...

Which I mean, you sometimes have to open, close, reopen Odin when it doesn't work.

Sometimes that helps, sometimes it doesn't.

It's all about the right Odin version at the time

making sure the cord is good

Opening Odin as Admin

And keep trying again after restarting your phone by holding the download mode button sequence again.

I know this all seems like a lot and it seems very confusing but it's pretty easy if you just follow the directions this will not wipe your data. Please do research, read through the forms and just tried to get as much knowledge as you can before you go about doing this it's an easy process but it's better to go in with more knowledge, I hope this helps. If you have to reinstall the firmware make sure that you install CSC home so you don't lose your data
