Bricked Galaxy S7

Can someone please help me out. I am a total noob at stuff like this. I have an AT&T Galaxy S7 Edge and succesfully rooted it the other day. Upon installing another app my phone was bricked (screen that reads unauthorized software has been put on AT&T device).
From reading and searching I am assuming that I have to flash back to the stock ROM. Can anyone please guide me through this endeavor, or lead me to a post where it has already been done? Thank you in advance.

You need to find the correct firmware for your device. I'm not sure where the thread is for it but once you get it use Odin to load the firmware and flash through Odin

You can use the Odin pj4 files to restore. Just Google how to use Odin. The pc side is self explanatory just put the phone into downloaded mode.

I have tried several versions of Odin and stock firmware for the s7 edge. Everything is failing across the board. I think I am just making it worse lol

Why don't you tell us what version of the phone you have exactly? Then maybe you can get more useful advice.

Unrooting to stock rom?

Hi,
I have been rooting my note 4 since it came out and familiar with any problems that may occur with kernels and stuff...
I decided to sell my phone and put it towards an S8 when i t comes out, i am sending my phone to Mazuma Mobile but wanted to unroot it first but the stock firmwares i am flashing though Odin are stuck on the Samsung start up screen.
I am not sure about unrooting and need some help, the latest firmware i have tried is "BTU-N910FXXU1BOC5-20150423120804" - i have the N910F model but it wont load beyond the Samsung bootup screen.
Anybody give me some help please and maybe point me to the correct firmware that i should be using?
Appreciate any help.
Thank you.

Think i need to use the latest firmware - N910FXXS1DQC3
Can someone point me to somewhere i can download this please?
Every link i check asks me to buy an upgrade account to down load this firmware.
Cheers

Help on which firmware to use.

I am about to root my Samsung Galaxy S7 - SMG930VLUDU4CQH2 for the first time and I am gathering the files for the job. I have read every post from the thread https://forum.xda-developers.com/tm...eres-how-rooted-nougat-s7-edge-g935t-t3567502 . I have the Qualcomm heroqltetfnvzw version so I am sure that I am using the correct thread. The two questions I have are :
- just in case something goes wrong, which stock firmware would I use to get back to original state? The BQA2, BQH4, or the BQA4? , after the Nougat upgrade mine is the CQH2.
Secondly, I have also been reading on the Magisk technique to root and was wondering if anyone has possibly tried both of these out and has compared their stability and lag (or lack of lag)? I understand that that it varies from device to device, I am just talking about the technique.
I have actually read so much that I am getting myself confused on this whole process. Lol. Thank you in advance for your help and I have started following several of the members. You guys rock! :silly:

I'm scaring to brick my phone. So how to backup all things ?

Hello friends,
I would like to install custom rom on my phone Note 4 sm-n910C . I'm not an experienced person for it. But basicly I know that I need to root my phone 1st then install suitable version of TWRP on my phone. And then I can backup my stock rom and all things. Then install custom rom file.
But I scare to brick my phone doing this procedure. So I wonder, can i backup my phone's stock rom and other all things (kernel, firmware, modem etc...) without TWRP ? I mean , can do it with pc software ?
And if my phone become brick, thus, can i restore it completely via pc then ?
If i can do that, how ?
I'll be appreciate if you help me ?

Choose your Country and phone provider and download the stock ROM from Sammobile
If it's needed then use Odin to reload it. There's plenty of guides how to use it including those that explain how to root. I recently rooted one of my Note 4s, a N910C and apart from using a slightly older version of TWRP was pretty straightforward.
I used this guide and the downloaded the files from the links in it but there's other's available but be 100% sure you're following the guide for a N910C.
I'm not that knowledgeable about Rooting compared to many people on here although I've rooted all my Tablets and Phones but seem to recall you may need to use an older version of Odin to do so. The most difficult problem I had was getting the correct driver installed that would recognise all my devices and even that was just persistence. Just read everything a few times and double check you have the correct files before you start, it's pretty straightforward.
In all the above comments I'm assuming you're using the last version of the stock ROM that was released.

@Big Elf
Thank you very much for your reply and explanation. I looked at your shared pages. And I'd like to start it.
But I have some quesitons to not make a mistake. If you guide me, I will be appreciate.
But before that let me share my phone feautres screen shots. You may see all detailed information.
SCREENSHOTS
I can't share links due to xda rules bcos I need to reach 10 post. So pls complete http section if it need for below scrshoot links.
1- drive.google.com/open?id=0B6aBME5e-tzcYk1zY0dqeTZaMVk4eEdWbjN4SWVPSEU3cXFr
2- drive.google.com/open?id=0B6aBME5e-tzccHF6UFpCT29JT1ozRUFoMUtmWmZ0V0J3c19z
3- drive.google.com/open?id=0B6aBME5e-tzcajVnMGkyMTRJdmo3OTNPc29SQXlEbkY0R3N3
And My Questions
1- First of all ty for rooting page. According to explanation i'm going to root my phone. But I wonder that android version is matter or not. My phone version is 6.0.1 as you see. Is it okay, its suitable for my phone, right ?
2- As far as I read on internet, There are all TWRP versions are different for all diffrent smartphones. According to above scrshoot informations, which is the suitable, stable and latest version for my phone ? And Where can i find it from ? Or if its possible could you forward me exact page and/or link please ?
Because my scared major thing is that. Wrong type of TWRP. And so brick my phone. Btw, let me ask, wrong version lead to brick phone, right ?
If I install the true type (version anyway) of TWRP then I will be relax. Because after that, process will be very easy for me. I experienced from Huawei's first phone "IDEOS X5" . I have installed TWRP and custom roms on it , on years 2012-2013. I only scare to make mistake via perform it on note 4 & brick it.
Thank you so much again.

You've made your first mistake . I explained you need to read everything carefully and double check you have the correct files before starting so that you're reasonably confident that you know what you're doing.
The link I posted explaining how to root also has the link to the version of TWRP and Odin needed to install and Root it but you didn't read it properly.
You're running the same version of the ROM I have on my N910C albeit a different country (which won't make a difference).
If you install the Official TWRP App from Team Win you can update TWRP after rooting. I'd also suggest installing the SuperSu (Pro) App from Codingcode which will update itself after rooting. I also use Root Checker (Pro) from joeykrim to check that root has worked and SuperSu has installed correctly. All those apps are available in the Play Store. I pay for the Pro versions as I appreciate the work that's gone into them and as a thank you to the developers.
You don't have to root it so don't feel that you have to do so.
Although all my phones are rooted my Note 4s (N910Fs and a N910C) still run the stock ROM and the main reasons I did so was to run Adaway and also to debloat neither of which are essential. I also wanted to know how to do it.
Installing another non-Samsung ROM has 4 main disadvantages:
You lose the fine control over the OLED screen including the boost mode in bright sunlight
You lose some of the functionality of the s-pen
You lose a lot of quality from the camera that you won't get back with any ROM.
Most of the ROMs have some faults other than those just mentioned but are usually but not always minor.

Can't find XAA or ATT binary 7 firmware. Please help

I have an AT&T Galaxy G950u with my most recent firmware being g950usqs7dtb1. I flashed a combination file (g950usqu7ask1) to turn on OEM unlock so I could install Havoc (I know now, I didn't have to do all that,) but now I can't get Odin to flash any stock ROMs back to install TWRP. The main error I'm receiving in Odin is FAIL! (Auth).
I've tried all kinds of ROMs but I can't find my original ROM anywhere except some shady site that definitely isn't legit.
When I boot into Download/Odin mode the numbers next to RP SWREV are B7(2.1.1.1.1) k6 S7
The error on my phone is SW Rev Check fail: (ab)) Fused 7 > Binary 1
I realized I probably need a carrier free (XAA) or ATT firmware that is binary 7. The problem is it's so recent I can't find any binary 7 firmwares out there. I've searched Updato and couldn't find xaa firmware for binary 7
Working with patched/modded Odin 3B v3.14.1
If anyone can help I would be so grateful.
Edit: I've tried Frija and it says ATT not supported, and it says it can't find anything for XAA. I've also searched Updato thoroughly and can't find a binary 7 file.
Edit 2: I found a ROM.

Well first off you can't flash any custom ROMs on this device it has a locked bootloader. Oem unlock doesn't matter. It's useless. Garbage. That's all for that. Flash any other carrier firmware and flash the oyn csc not home. It will repersonalize for att as the firmware are actually multi carrier. Att included.

Thanks for the input. I'm trying to flash twrp as a custom recovery but it gets stuck on "waiting for device". I've updated all drivers and have no error in device manager

Hey there @TheMadScientist not following you! haha. Just came across this thread as im researching what elliwigy and jrkruse have done.
To @uberdad search for anything s8 SM-G950 by jrkruse and elliwigy here and you should have a solution if your device is still on 7. Wont be twrp but will be safestrap twrp. You can install a custom rom then.

There are no custom roms. You can only have root on a 7.0 stock system img. Please research more before beginning to pass on information. As well this thread is now old no need to dig up old stuff. I helped out with some of the stuff on this device I know what it can and cannot do. Here wanted to install a los based rom. which is a big no. Add I said to begin with
---------- Post added at 03:57 AM ---------- Previous post was at 03:50 AM ----------
Then he was trying to flash twrp. Which is a big no. Please don't go dragging up a bunch of old threads we have dealt with. This leads to confusing people

Hi. Yes you are right I should have said Slightly Cooked Rom or Modified System Image. However preferred to put Custom Rom due to the fact the amount of new Customization Enthusiasts here on XDA to make it simpler. Also sure yes USER Root on XDA only obtained on 7.0 (at least public). Little off topic but our team has a *working* root along with our own SuperUser which means for repairs pretty much but if time was put into it could become possibly a semi to full user root. I have used Magisk SU older versions along with our root and had a semi working user root on past Galaxies.. Anyhow we don't really have time, especially myself, to work on an actual user root for every device i/we work on.
In the world of forums threads never really grow old they just go into a deep sleep eventually....Until someone wakes it up with the thirst for knowledge. It's how the internet works when it comes to these here BBS/Forums/Blogs etc. =]
What he asked could be something someone else might ask or attempt trying (he shouldnt have even got as far as he did unless on international variant which makes the Q odd.. haha eh? however i felt the need to straighten it up for anyone who might read and get confused. See what im saying..? along with the previous statement about data no become stale.
The more ya know the smarter you become. Information makes the world go around. .. IMO Always best to keep it flowing constantly added to.
