Just received a new device from at&t, tried flashing per the instructions and the first version of Odinn gave me sha256 errors. (using firmware on the first page)

The PrinceComsy version gave me a "sw rev check fail" and resulted in boot loop. (using firmware on the first page)

-Odin version here https://drive.google.com/file/d/0B8c1zN7zrnVhM3JNWGtROUJPQW8/view

After downloading the nougat 935U version I flashed with the PrinceComsy version successfully.

Firmware download was from here https://mega.nz/#!zgFzzAYY!_Vo6tr61lwG8XaZNpFqkupaucsRRCv-6ULKylG38uyI

Although you can also get it from Sammobile here https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935U/

- There were two CSC files, I used the first version without the "Home" preface.

I hope the OP updates the first post for those that have had difficulty with devices that come with Nougat.

I don't know if flashing ATT radio was needed, but Samsung disables some bands depending on device (T, U or A). I thought I would be better off with ATT Radio

Yes. I have a carrier-locked 935A running the unlocked 935U firmware. It's still SIM locked to AT&T, but it now thinks it is a 935U in every other way.

It is also massively better in just about every way than the original AT&T firmware with a few exceptions - which may not apply to you. AT&T no longer recognizes my phone as being supported for WiFi calling or VoLTE.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] cnewsgrp:
I have not noticed any changes, however as per internet here are LTE bands for each radio

U Radio: 1, 2, 3, 4, 5, 7, 8, 12, 13, 18, 20, 25, 26, 29, 30, 38, 39, 40, 41 (http://www.droid-life.com/2016/06/30/unlocked-galaxy-s7-s7-edge-us-bands/)

A Radio: 1, 2, 3, 4, 5, 7, 8, 12, 20, 29, 30, 38, 39, 40, 41 (http://www.gsmarena.com/samsung_galaxy_s7_edge_(usa)-7961.php)

Clearly U radio has more bands so should work better.

For ref Here are 935T bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 20 (http://www.gsmarena.com/samsung_galaxy_s7_edge_(usa)-7961.php)

I am not an expert, but based on the readings I did, 935A, 935U and 935T have same hardware and flash is allowed meaning you can flash either firmware on any device, not sure if 935V falls in that category

You lose voice over LTE (VoLTE}, not LTE, and only because AT&T doesn't support it on anything they haven't touched. The reason people prefer it is the lack of bloatware and lag, and the corresponding improvement in battery life.

Keeping in mind that AT&T (and probably T-mobile, but I have no experience with them) is well known for jacking around with the signal strength meter. The one in the U firmware is probaby the most accurate.

Before installing a new radio, check the actual signal strength. You might be surprised to find that it hasn't change at all, while the number of bars it represents has.

1) No kidding. Most carrier firmware is bloated as hell, and AT&T has always sucked harder than usual in that respect. I remember it being awful as far back as Gingerbread on the S2.

2) If you can get into download mode, your phone isn't bricked. Bricked is "won't power on at all". It is exceptionally hard to brick a bootloader locked Samsung device.

3) The first post in the linked thread has working download links near the bottom. They are not dev-host links, they are from a private web server. I know, because I used those links yesterday to get the most recent U firmware and ODIN installer.

Unlock it first

Another rookie Noob here. Unlock it first if you want to have all network protocols working. Could one another sneaky way to prevent you from being able to use other protocols. might even prevent you altogether. I just got this process done yesterday, after trying to do this since January 23rd! Bricked my phone really good too. Was in a boot loop and so was recovery. For a couple of weeks, I thought I had killed my S7. The battery died in January and I ordered a new battery (14.99) for this Non-replaceable, non-repairable S7 Edge, not a scratch on it, paid it off a few days later and really was tired of all the interference my carrier had been doing, had internet and TV with them and was determined not to let them basically steal my phone. I downloaded Odin 3.12.7 and was able to return to stock G935AAUCS4BRA1. It even showed as a custom Rom. After a few reboots, that went away. Last night I then install the rom per the instructions, it must have updated 4 times or so and now has G935UUES4BRA1 AND I NOW HAVE MY PHONE ON MY NEW CARRIER! ( Who also wanted me to buy another proprietary phone!). The new product code is SM-G935AZDAVZW. Old provider said five tried 5 failed unlock attempts would permanently lock my phone to them so unlock first and it took until last night from 1/23/18 to know for sure it had been unlocked when I got the U rom installed. Now the question is, try to get Oreo or this really cool rom I saw on here. Just hoping the dev will grant me permission!

So I'm a little bit confused.....I have ATT version of S7 Edge, it is "unlocked" phone. I would like to bring the phone to Ting, but I learn that operator specific features like WIFI Calling or VoLTE will not work unless I have vanilla / plain ROM.....so what version do you recommend to install on the phone?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] nomad247:
SM-G935U

What I did was to root the phone, and then installed a U Version. IF YOU are not using a USA variant, I would look for the F variant. F is International, U is universal. I have a US variant which have locked bootloaders, BL. There is the carrier unlock which you said you have. But to get the bootloader unlocked, you have to root and that could trip KNOW which makes some apps not work. When I rooted, KNOX show 0x0, not tripped so the apps like Samsung pay should still work. Search your model on sammobile and download your current mod and either a U variant or international. Search for how to root your model. It worked for me, my ATT S7 edge, is now on Verizon network. The point is, the carrier branded phone has only the network protocol they use, the U and F mods have all network protocols or bands enabled so you could use ALL carriers. So get your firmware the one you have now and the variant that will work best for you, find the root method for your phone, root it (unlock the bootloader), the install your new mod.
