How to root the Samsung Galaxy S7 and S7 edge (Exynos)

How to root the Samsung Galaxy S7 and S7 edge (Exynos)
The Samsung Galaxy S7 and S7 edge versions powered by Snapdragon 820 (all US carrier models) come with one unpleasant surprise in the form of a locked bootloader. This means that the modding community is going to have a pretty hard time to root and create recovery for these phones, paving the way for all the wonderful things that good custom ROMs bring. 

Their owners would have to wait for Android N to hit their handsets officially, for instance, which, knowing Samsung, may not happen before this time next year. Any battery life optimizations, bloatware stripping, or TouchWiz enhancements that need root will also be sorely missing for quite a while on US models, too, as those are often the benefits of custom ROMs for those brave enough to go there.

Fret not, however, as T-Mobile's flamboyant CEO John Legere would try and come to the rescue, and has apparently ordered his engineers to probe Samsung on workaround solutions that will satisfy all parties involved. He is not doing this only from the good of his own heart, though, as some users have reportedly started returning their phones with locked bootloaders, seeing that there will be no modding development for a while.

Funny this is exactly what I said in the other article you posted about it. If rooting is important to you, the International model of the Galaxy is always unlocked bootloader and can easily be purchased directly from Samsung and from a retailer or carrier outside the USA. Based on my experience, other than wanting to remove the carrier/Microsoft junk, rooting bring no real benefit to the Galaxy except to add a bit of speed. If you want a stripped down version of Android, seems the Nexus would be less of a headache if their phones werent always so boring looking.

Not exactly. You don't need root to turn off the junk on touchwiz. There is an app called package disabler pro. If you give it dev permissions, it can disable ANY app( yes, even those which Samsung doesn't allow you to). It's a paid app but well worth it. I downloaded it and disabled 140 packages. Now I have only the bare essentials on my phone, with the Touchwiz features I use. All the data sniffing apps, useless background syncs and just pure bloat is gone. My phone is basically stock android now, with important TW features like multi-window, themes etc. The result was astonishing. Free RAM went from 500 MB to 1.2 GB. Battery life increased tremendously(duh!) and my phone barely consumes 1% battery in 4 hours standby(with WiFi and auto-sync on). And this all can be done without root. With root, you have the world open to you.

I did the same thing on my Galaxy S5 which lagged like hell after a few months. I had about 100 stuffs disabled. It then became speedy!

Lack of Ram caused it. 3gb Ram is useless.

A dumb question to the wise one.....how do you know what stuff can be deleted and not cripple your phone

11. tyrionTheWise unregistered

The app provides an automatic option called "disable all bloatware". That disables around 120 services. From there, I take a tour of the services and see which bloat the app missed out. It's pretty clear that no one needs 'Samsung push service' or 'Samsung cloud sync' etc. Most services are clear by name. It's not deleted. It's just disabled. If someone does a dumb move and disables something like 'system UI', he can boot into safe mode and revert the changes. Also I have done courses on linux OS. So pretty sure how processes work on android.

Can't you just disable them in the apps manager rather than using an app for that?

16. tyrionTheWise unregistered

System apps can't be disabled in the app manager. Try to stop com.facebook process for example. You can't disable it and it turns itself on even if you force close it. Given facebook's history, I can't make it run in background all the times since it can track anything. There are a lot of apps like this. You need this app for those kind of junk.

I hang out at XDA Developers and the senior members usually post their findings from experience. but they can be fallible. It mostly comes down to trial and error. you freeze a couple apps then see if anythings locks up on you, then do a couple more, and so on. I've been doing it for awhile now, so I just zip through it with SD Maid. and I've got the gist of it. Drat's didn't post where i wanted it.

You can disable those too. Until now I saw the purpose of rooting phones. But now I have a good/eficient battery consumption, speed and others goodies always on. No need for Greenify, CPU throttle or root tools for uninstall junk Samsung or Carrier apps.

There will be no AOSP/CM roms for the Exynos version due to Samsung only providing certain pieces of code. The unlocked bootloader will only allow for custom kernels and TW roms based on what Samsung has already released. As someone who has had an S4 with AOSP for almost 3 years this kind of sucks. TW is a huge resource hog and def not as smooth as a clean Android experience. It's not for everyone but if you are willing to pay $700 for a device then you should be allowed to mod it as you please.

And all the crap from the snapdragon fans about it being more dev friendly. Qualcomm secure boot is going to put even root off the table.

Qualcomm Secure Boot tarnishes rooting? Wow, things are turning up-side-down now.

Doesn't root make Samsung pay unusable? Or Samsung disables it or something.

That's why they locked all the sd820 down and also used them in the USA, as they al, like to unlock there phones, and ssmsung needs them using Samsung pay

Its funny how quickly this article is up after the whole debate the article about the locked down bootloader had, people being outrage, and yet turns out to be this easy to get around.

Will it trigger Knox and void the warranty?

I got something about a security check error right of the bat when trying to root it. Both on the phone screen and on ODIN. anyone know what that is about? it caused my root to fail.
