[Galaxy S6 General] djshotty:
Shotty's 920I Nougat Helper Post

Now, I've only just changed this post around temporarily, because I could only find a 'Free 'n' Fast' download link to the stock Nougat ROM for the 920I. If you have a S6 Edge and need help flashing in the correct ROM, this guide can still help you with the physical tasks of doing that.

Okay, for those of you wanting to run the Android Nougat v7.0 operating system on your International variant of the Galaxy S6, here's one of the most detailed 'How Do I Do That?' posts you'll find on XDA for upgrading your SM-G920I to what we call Nougat 7.0. Only thing I've got to say before you begin?

If you can't follow instructions and you brick your phone,

don't blame me and serve yourself right.​

First, you'll need to backup your photos, music etc. to your PC. You want a completely clean slate, and the whole operation goes a lot smoother and faster if the firmware doesn't have to dodge its way around existing app. files and photos+videos+music files. Do whatever it takes, but setting the phone back to what it was like the first time you first put your SIM card in it is what you're aiming for here. Me myself and I? I 'rooted' my phone, and use Titanium Backup Pro:

Main app. installer: https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup&hl=en

Pro Licence for AU$7.47: https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackupPro&hl=en

to backup the apps and data I want to keep. Next, I copy the music, photos and that Backup folder to my computer, then go through and delete everything I can access (except the Android folder) before disconnecting it and going into Settings and doing a full factory reset. I let the phone boot into Recovery, where I do another full cache wipe + factory reset, then Power Off without rebooting the phone. It's only then that I restart into Download Mode and flash the new stock ROM, after my phone has been fully cleared of redundant files.

Now, you need the latest Nougat 7.0 stock firmware for your device. Fastest way to get the unbranded Australian ROM - G920IDVU3FQD1 for Galaxy S6 - without needing Premium accounts or waiting while bandwidth throttled filehosts drip-feed you over 1.7 gigabytes of data, is to visit zxz0O0's thread over at:

http://xdaforums.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647

which will then direct you through to the following download link:

http://fws02.updato.com/GALAXYS6/SM-G920I/XSA/SM-G920I_1_20170405150613_v655x8d07h.zip

If you click on that link above, the download should start through your browser automatically. If you have one of those 'Download Accelerator/Manager' programs, copy the link and paste it into that program for an even faster download. It's 1.805GB in size, by the way. Once the ZIP is fully downloaded, you'll need a program like 7ZIP or WinRAR (for Windows PCs) to extract the ROM file needed by Odin to 'flash' into your device.

So, XSA isn't your Country Sales Code? If you don't know your region's CSC, go to https://samsung-firmware.org/model/SM-G920I/, hover over the three letter codes and it (most times) tells you what country those three letters represent. Here's every CSC for where the 920I (and 925I) was sold...

You now need to put your phone in Download Mode - the yucky vomit aqua-green screen you get to by switching your phone off then restarting it like this:

With the phone in your left hand, left thumb pushing down on the Volume Down button, right thumb holding down the Home key and right index finger floating above the Power button, push and hold down the Power button until a Warning screen appears, then take your fingers off all three buttons. Next, press the Volume UP button, then you're in Download Mode.

On your computer, run Odin, click on the AP button, locate the ROM you just downloaded, and load it up. Plug your phone into your PC, make sure Odin discovers the device by putting 'Added!' on it's window, click Start, and you're away. Oh, and DO NOT disconnect the phone from your computer until Odin says 'Removed!' in its window. Then it's just a case of waiting for the phone to boot up to the first Welcome screen.

Be aware, the above process DOES NOT trip the Knox counter, nor will it reset that counter, but I will say it takes a few minutes for the device to install the updates.

Now, two things I do as soon as I get the stock ROM running are turn ON USB Debugging and change the GUI responsiveness. Go into your phone's Settings menu, scroll down to and tap on 'About device', then tap 'Software info'. Find where it says 'Build number', then tap on it seven times until a popup appears, 'Congratulations. You are now a developer'. Hit the back button twice, and you'll see a new menu option, 'Developer options'. Open that menu, switch (up the top) ON if it's not already, switch USB debugging ON then scroll down to these three options:

Window animation scale

Transition animation scale, and

Animator duration scale

Set them all to 0.5, and you'll notice straight away your device feels a lot 'snappier' and quicker to open and close things.

Okay, I'm awake on Nougat.

HOW DO I GET ROOT ACCESS?​

Well I'm glad you asked! Now that Chainfire has written his CF-Auto-Root packages to suit the 'I' variant of the 920 and 925, there have been a number of owners both here at XDA and on other forums who have reported this method as working properly, myself included, and they work REGARDLESS OF WHAT YOUR ROM's Country Sales Code IS!

PLEASE NOTE: This of course WILL trip the infamous Knox counter, which in many markets also voids your warranty. It's why I cannot stress this enough - follow the instructions below AT YOUR OWN RISK!!!

As of the time of writing this post, I am unaware of any method or app. that resets the Knox counter once it's been tripped, so

(a) don't root your phone if you need Knox for your employer's specific security and networking apps,

(b) stop right now if you don't want to void your 12 month warranty, and

(c) don't EVER ask if there's a way to reset Knox if you've tripped it.

For 920I users, download the following ZIP file from the legend that is Chainfire:

https://download.chainfire.eu/733/CF-Root/CF-Auto-Root/CF-Auto-Root-zeroflte-zerofltexx-smg920f.zip

For 925I users, download this version of CF-Auto-Root:

https://download.chainfire.eu/737/CF-Root/CF-Auto-Root/CF-Auto-Root-zerolte-zeroltexx-smg925f.zip

Okay, how do you 'root' the phone?

Extract your device-specific CF-Auto-Root archive to a New Folder on your Desktop, and have that folder open and ready,

Turn off your phone then reboot it into Download Mode (Volume-Down + Home + Power buttons together),

Run the included version of Odin3 v3.10.6,

Click the AP button and the program will ask you where the custom recovery you need is.

In that window, navigate to and select the CF-Auto-Root-zeroflte-zerofltexx file,

Click on Open and Odin will load it up ready to flash,

Connect your phone to your PC via USB cable,

On the Odin program window, make sure the first box on the left is light blue,

Make sure the word 'Added!' is in that text box on the left hand side,

Click Start,

When done, the phone will

(a) reboot into CF-Recovery,

(b) trip Knox,

(c) install SuperSU, and

(d) reboot a second time.

Happy days, you have permanent root access!

Australian Galaxy S6 users are finally rejoicing now that Samsung have finally released Nougat ROMs for the XSA sales region. Of course, we still await the slowpoke service providers - Craptus (OPS), Vodafail (VAU) and Turdstra (TEL) - to bring out their bloatware-filled carrier-branded versions. I have it on extremely good authority that these providers are currently working on their individual ROMs, so if you just can't live without your phone booting to your carrier's logo, call their technical support teams to harass them about the delays. Of course, don't let them blame Samsung!

Enjoy, kiddies...
