This is for the International SM-G935F/FD/X, Korean SM-G935K/L/S, and Canadian SM-G935W8 Exynos models only! Do not flash on flat S7 or Qualcomm models!

WARNING #1: Flashing a custom recovery to your device will trip the Knox warranty bit on your phone. Check with your mobile provider to see if they will still cover warranty on Knox bit triggered devices. If you understand this risk, continue on.
You generally don't have to worry, as it's incredibly hard to brick a Samsung device, and physical damage warranties should be exempt from Knox triggering.

WARNING #2: The Galaxy S7 stock boot image has dm-verity, which prevents you from booting if you swipe to enable system modifications!
SOLUTION: Follow the full rooting steps below, in order, to allow system modifications without the risk of a boot loop!


WHAT IS TWRP?

Oh come on, you know what it is - don't try to fool me!
In case you're serious, though...

Team Win Recovery Project is a custom recovery for Android devices.
It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, and root your device.

DOWNLOAD

You can find the device page here:
http://teamw.in/devices/samsunggalaxys7edge.html

There is a download link there, as well as instructions on how to flash it.

I highly recommend using Odin to flash when possible.
You can find a zip containing Odin as well as Samsung's Mobile drivers here:
https://build.nethunter.com/samsung-tools/

FULL STEPS FOR OBTAINING ROOT

You can follow this video by Max Lee if you'd like: How to Root Galaxy S7 & S7 Edge! [Exynos ONLY]
Otherwise, follow these instructions:

  1. In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.
    Transparent.gif
  2. Now go to Settings -> Developer options. (above About device)
    You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.
    Transparent.gif
  3. Extract Odin_3.12.3.zip to your computer.
    Transparent.gif
  4. Install Samsung Mobile Phone Drivers for Odin to find your device.
    Transparent.gif
  5. Download a .tar image of TWRP for hero2lte.
    Transparent.gif
  6. Reboot your device into Download mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Home] buttons while your device reboots.
    Once you reach the Download mode warning screen, press [Volume Up] to continue.
    Transparent.gif
  7. Open Odin and place that TWRP tar file in the [AP] slot and disable Auto-Reboot, then press [Start].
    Transparent.gif
  8. Hold [Volume Down] + [Home] + [Power] to get out of Download mode and immediately swap to [Volume Up] when the screen blanks.
    If you don't see then TWRP boot splash try again from step 6.
    Transparent.gif
  9. At this point, you will reach the screen asking you if you want to allow system modifications.
    By swiping right, you will trigger dm-verity, and if you don't follow the next step you will be unable to boot!
    If you are going to root your device and follow the rest of these steps, then it is safe to swipe right and enable modifications.
    Transparent.gif
  10. If you want to be rooted with SuperSU:
    Download the latest SuperSU by Chainfire.
    Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
    You will need an external SDcard for this method, if you don't have one you will have to use adb sideload to install SuperSU.

    If you only want a bootable system partition:
    Download the latest dm-verity and force encryption disabler zip.
    Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.
    Note: This does not disable the forced encryption on Bxxx firmware, only Axxx firmware due to a change in vold by Samsung.
    Transparent.gif
  11. Go to [Reboot] -> [System].
    Transparent.gif
  12. Wait 2-5 minutes for your device to finish setting itself up.
* MTP, known as Media Transfer Protocol, is the same way you transfer files from your PC to your device when booted into system.

If you have a G935P, G935V, G935R, or G935A (aka the US Snapdragon models) your bootloader is locked. I will not be making TWRP for your device - it simply cannot happen. Sorry.
Update: G935T users can expect TWRP for their devices as soon as T-Mobile convinces Samsung to unlock the bootloader - I already have a fully complete working build ready.

You know who you can blame?

THE DONALD!~~~~~~~~~~~~
or Obama, I dunno, blaming Obama is getting kind of old guys, sorry.

Is this for the Snapdragon or the Exynos devices or should it work on both? And does this also apply for the kernel?

It specifically states in the title G935F, so it's for Exynos.

Can I ask if someone on a Vodafone UK handset tries this, let me know if it works and confirms an unlocked bootloader. I'd do it myself but I'm still undecided whether to keep this thing and that could decide it for me. I'd almost certainly have problems with a return if knox is tripped. Cheers!

I wonder if this TWRP works for all G935 variants. I do recall that TWRP worked mainly for most note 5 and S6 variants regardless of model.

you're in the Exynos forum

Thunder Bay! Nice city, I visit often. Glad to see someone from Canada working on exynos version!

This will only work for G935F (and possibly G935FD?) which are the only known Exynos variants of S7 Edge.

I will be working on the Snapdragon variants as well once their sources are released.

Forgive my ignorance. What differentiates the Exynos from the Snapdragon version as far as name? And how can I identify the Snapdragon version? I NEVER know where y'all find all these names for these devices. LOL

Actually, I think I found it. Snapdragon is the SM-G935T. Sorry for asking.

AFAIK they ate the processors. Both are totally different architectures, so this being built for one literally means it won't work on the other.

Generally I believe Exynos is international whilst snapdragon is everywhere else. I'm not sure what constitutes as international however.

Thanks, I appreciate the info. I'm aware of the different architectures, etc...Just wasn't sure how the names differentiated the two variants. But I've tracked it down and will hopefully be able to find it in the future. LOL

Flashing anything custom will trip Knox. So 0x1.

Would really be appreciated if you could confirm. Is it a UK Vodafone handset you have?

    Hey guys :) :highfive:

    Some may know me, some probably not. It's not important who I am BUT I found that our device tree for TWRP builds is damn outdated (based on MM).

    I don't know if you faced this issue already, but some people couldn't mount /data partition in TWRP even though they removed encryption. Why this happens?

    Explanation:
    Samsung added quota support in their oreo update for the /data partition. Means a TWRP update with proper quota support is needed to get this new feature to work. Till now, many developer simply disabled this feature again on their kernels (so they can mount /data without issues on the old TWRP).

    What I did:
    I updated the tree with the latest files, kernels and so on. Including the above mentioned quota support.

    This TWRP version works on stock and supported oreo kernels. Older kernels (which removed quota to fix mounting problems) won't work here. Please advice your kernel developer to update his kernel with the changes :good:

    tar.md5 file (flash via odin)

    I will need someone to verify if features are working as this was just a copy paste of the herolte (non-Edge) device tree.
    Mainly expecting brightness slider to not work, so please if things don't work, join #twrp on freenode and talk to me.
