It's gotta be that csc file of the FW then. So even though the FW is the same for all the variants, they must have different csc parts that will allow stuff like that. If we can find the att U FW then we could get it also.

I can't believe they were able to block the unlocked version from releasing the FW also..

If someone can pull out the csc.txt from AT&T S7 Edge G935A and find a way to put it in G935U then it will have the AT&T Function.

Edited: Also if adding Build.prop from the AT&T S7 Edge G935A it will bring back the network icons and LTE Enhanced. And some AT&T Function, but it's also possible that the LTE Enhanced is also a apk, samething with Video Call.

Any idea what you'd need exactly to try that? I have the June FW downloaded for the 935A and can try picking out files to test

A little off topic.

Since we are dealing with rooting/flashing in this thread, I was wondering what others are doing about backing up their data before wipe? One of my main issues with wiping my device is I end up losing all of my Google Play Music All Access downloads on my external SD Card. It's a huge pain to re-download all of the music. Any tips?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Skizzy034:
The file in the other thread for the stock 935A FW should have the csc part of the FW. Just try putting that into the csc Odin slot, but use the ap, bl, and cp of the 935U FW.

Yes engboot is just as bad on U.

No other root method exists.

You're also giving up AT&T-specific bloatware

Are you using Nova Launcher?[/QUOTE]

Yes. Using Nova Launcher and Chronus homescreen widget. I got all that set back up- I was just being a baby complaining about re-setting those up.

Some observations after a morning with the 935u flash:

- Boy howdy is this quick and smooth! I love not having any of the ATT crap! This is a MASSSIVE improvement in my overall quality of life with this device.:highfive::victory::good:

-Amongst all the voLTE and wificalling issues, I thought I had read that one loses video chat with the 935u. I tested this and made a call with Duo this morning and it worked great. I was on wifi (dont know if that makes a difference). Pehaps the video quality was just slightly worse but it wasn't enough to complain about.

- Speaking of wifi- my phone automatically connected to my office secured wifi this morning without having to put my password in. How is that possible??? I had to log back in on my home wifi after I flashed last night. :confused:

- When I back out of settings (using the back key), sometimes it puts me back to the touchwiz homescreen until I hit the home button and that pulls up my Nova Launcher setup. I just checked default apps and Nova is selected for homescreen. :confused:

- Some of my contacts are gone as well as all my text messages and some of the pics I didn't have on my SD card. I took the time to run a full backup and create an update.zip on my SDcard with Titanium before I flashed the 935u - but I didn't realize I would lose my root. Any suggestions on how to get this data back on my phone without the janky root, pleeeeaaase???

I'm a big fan of the implication of whitepages. Really helps, shows contact info even in sms or if you're calling an unsaved number too
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] smknutson:
I'd look into using greenify with aggressive doze, and using package disabler

---------- Post added at 12:25 PM ---------- Previous post was at 12:15 PM ----------

-The video calling is only lost in the stock dialer. Third party apps won't be affected :)

-I think Google saves wifi passwords in account sync. May not be perfect though. Mine does the same with my home wifi during setup, which is normal but it also must save my work wifi to my Google account as I automatically log in as well.

-look into using EZ Disabler or Package Disabler Pro in the PlayStore to disable the TouchWiz Launcher and any other bloat.

-contacts and sms are probably saved using AT&T backup, right off the bat they will not transfer to U, and I'm not sure about installing the necessary AT&T software to see if we could have that functionality..

-Other than somehow pulling the pictures from the .zip, I'm not aware of any way to load the texts and pictures without root.

---------- Post added at 12:27 PM ---------- Previous post was at 12:25 PM ----------

I've found the contact info for sms is generally incorrect about 75% of the time, pulling up previous number owner names.

Great. Thanks for the quick response! I will try a package disabler if the issue gets annoying. It's not too much of a hassle right now. I didn't think to use ATT backup- I will go and get that to see if that brings my contacts and texts back.

If I can get the text and contact data back from ATT backup, then the pictures are all that I know of thus far that's missing. How do I get the pictures back on to my phone from the titanium backup?

:( Bummed, I went ahead and paid the $5.99 for the upgraded Titanium last night as this is the second phone in a row I've rooted and figured I would continue to make use of it. Maybe we will get a proper root and I can get my money's worth at some point.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] tnowakow:
Price of a coffee, i'm sure you'll get your money's worth in no time, it's great to support the devs. You CAN get your pictures back by copying the zip to your desktop, unpacking it, then going into \storage and looking for a DCIM folder, they are all there.

FM Radio in U?

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] MajicManDroid:
After doing some reading in this huge thread I'm seeing that if you have an ATT branded S7E that VoLTE doesn't work. Does that mean that you cant be on the phone and use data at the same time? My S7E is still on its way to me and I'm trying to decide if i want to flash this.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Nope. It doesn't mean that. When you're on a call it does what all ATT calls do when you do both data/voice and throttles to about 64k/s.

I've been super happy, I used volte for a while but decided I can use whatsapp/Skype for business calls and we lose WiFi calling also (big battery drain anyways). The U firmware is definitely solid. All things considered, I just like debranding. F att

Another plus i forgot to add, if you're on Legacy Unlimited Data the U firmware comes with a perk, WiFi tethering works out of the box.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] nugzo:
I 100% agree. The new ATT firmware is a battery hog also.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Anybody on the newest A firmware turn off WiFi calling when you don't need it. It polls gps and eats battery. Turning that off for me helped a lot, still went to U though for tether.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] MajicManDroid:
Awesome. Really the only worry I had about the U firmware was simultaneous voice and Data. Tethering will be a bonus but really now I just need to search the thread and find the latest U image and install instructions. Thanks for your reply.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] jawonder:
What's the reason not to flash the HomeCSC file ?.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] smknutson:
Just don't. You like your phone's ability to connect to the proper networks? You like it's ability to not boot loop? Don't flash it

Csc instructs the device to wipe itself. Home csc instructs your device to only wipe the cache. This would be ok for a U to U version update... not for going from AT&T to U.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] jawonder:

Here's a new observation/question.

I use spotify almost exclusively for my music in my car. When I was rooted, for some reason, my spotify widget would not work to control my music and neither would the controls on Next Lock Screen. When I flashed the U firmware, I was delighted to see these worked again... Well, they've stopped working again.

This is extra annoying when I take a call in the car and my music keeps playing. On stock firmware, the music would stop when I got a call. Now it keeps playing and I have to get out of the call screen and enter the actual spotify app to pause it. Can anyone give some suggestions on how to make the controls on the widget and the lock screeen work? Even better would be how to make the music stop when I get a call.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
A stab in the dark. Is power saving mucking with it?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] slowbear:
So I just turned off power saving for Spotify and Next Lock Screen (as well as Tesla unread in hopes that I can get it to catch my messages in Google Messenger- Tesla unread used show a permanent 1 on Google Messenger no matter what, but it worked for the first time after flashing the 935u and now it has stopped showing a badge at all.)

To elaborate further on the Spotify issue though, I can skip songs on the lock screen and pause as long as I'm not on a call. The widget on my home screen only ever allows me enter the app. It wont control anything. But it did right after I flashed the 935u. Crazy, huh?!

Hi there. I tried and it works 100 for the TMO G935T flash with G935U tmo version. Make sure used the latest Odin and not the modified version. My first try was an G935T with Bad IMEI and couldn't get it to work, phone keep rebooting randomly, had was to flash modified recovery to boot up. I flash G935U firmware on my other 2 G935T just time with ALL TMO U FIRMWARE. The phone boot and that was it, 12 minutes on flashing the U FIRMWARE on them. I'm using the phone right now, operates so much better. Feels like a new phone, but it's the same phone. :good:

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Raven2k360:
Figured I'd jump in with my recent experience because...hey, why not? So I've been running rooted U BL2 since June, and it really started pissing me off - ****ty battery life, lots of app lag, etc. I was reluctant to move back to unrooted and/or stock, because well...I was just being a ***** about it. Honestly, I was holding out on an update to U to see if it enabled WiFi Calling on AT&T's network, but since it didn't - I finally went back to stock back on 10/20. I went directly from rooted U BL2 to latest bone-stock BL4 (G935AUCS4API2) in Odin without any issues, either during the install or after. So far, the phone has been AMAZING (at least, compared to the pile of **** rooted kernel), and WiFi Calling works like a champ...so I'm happy. Stock firmware for me is smooth as silk, no lag, apps are snappy, and the battery life is awesome - again, compared to rooted kernel. I do have the BL4 U firmware if I ever decide to go back, but honestly - unless I can't get tethering to work in the rare instance I need it (it didn't give me any notices when I turned it on with the stock firmware), I'll probably just stick to stock. Just my 2¢.

As to how, if anyone is curious -- Used Odin 3.12.3, downloaded from sammobile (I think), loaded all 4 files, checked Re-Partition (Auto Reboot and F.Reset Time were already checked), and hit start. Also made sure latest drives were installed from Samsung's site.

**Edit** Also followed the instructions on this page (http://xdaforums.com/att-s7-edge/how-to/to-drastically-reduce-android-battery-t3445291), though I didn't find a process called IQService - but found the other one).

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Raven2k360:
Everything seems to be working properly - I was concerned about that as well, I remember the early problems going back to 'A' from 'U' a couple months ago. IIRC, it was fixed with the July update of 'A', someone had gone back after that and their phone was working fine. As far as I can tell, VoLTE is enabled for me, and I can make/receive both calls and texts. I do remember the issues before the July update with people going back to June's 'A' firmware - they ended up having to go back to Feb and then OTA update or something, as well as some having to change something in the others.xml file, then repartition when going back to 'A' and everthing was good. I've been watching this thread like a hawk...lol. Those issues were also part of why I held off on ditching the rooted kernel and/or going back to the 'A' firmware. Once that issue seemed to be resolved, I was waiting both due to the bootloader update and to see if 'U' enabled WiFi Calling without having to root, and whether it would work with AT&T if they had. Since none of that happened, I finally decided to just go back to 'A' and have my WiFi Calling, and be done with it.
