Horrible experience. I've done all the tweaks mentioned for battery life and optimization and I've been awake for a couple hours.. Phone at 100% when I woke, sent a handful of texts and some light browsing... Now it's at 77%

Not good. I have yet to be able to stay rooted beyond the first reboot. My first attempt lasted 4 days, then a number of apps began stopping, so I rebooted. After a few attempts on A, U & APG1 I achieved root again on A - until flashing v15, which rebooted the system & I lost root. SU has always remained after the root loss. Right now, I still have SU and have 2 root checker apps out of 4 saying I'm rooted...but TiBu says no. I see from a thread on the S7 board that others there are having issues similar to mine.

Oddly enough, after going back to root... it feels like my battery life is still suffering. I may attempt to root once more time but I need to find some solid instructions and links in a thread that have the least amount of complaint. Possibly try the U firmware to see if that avoids carrier bloat

Was rooted for about a week. Did all the tweaks and battery life still wasn't great.

I remember I rebooted my phone while on vacation. Don't remember why exactly but it was just a reboot. Phone was stuck on the AT&T screen. Restarted and did the same. Factory reset my phone and problem persisted.

I finally flashed stock files and battery life was amazing. Phone would last over a day with 6-8 hours screen on.

When I got back home I received the July update with wifi calling and advanced messaging. My battery life went back to how it was when I first got the phone.

I'd only get like 3-4 hours screen time on and about 14 hrs phone on. Android system again is at the top of the list of usage.

I also use package Disabler to debloat the phone. But nothing special with this update.

Hopefully we can get a new update soon. Really missed the battery life I was getting when I went back to stock.

Sorry, can see how I was unclear lol but I switched to U + Root for battery life but I've been disappointed with it so far. Gave it a week but I'm switching back to stock tomorrow cuz I actually got better battery life.

Stock battery life was great! I rooted and the battery took a big dip...so i went back to stock. After a few days i couldnt help myself and rooted again. Someone suggested using L Speed in one of these threads. I tried it and now im rooted and battery life is almost as good as it was stock. It seems like everyone is getting different results with everything when rooted.

I'm planning on trying to root with U today and follow ALL of the battery optimization threads out there. I think I found three offhand, one of which was the L Speed.

I got the U installed and am thinking I may just roll with this stock for a while and compare battery life to what I'm used to. Shouldn't be any issues with that, right? Worst case, I figure I can just continue my attempts and put root on. Since there is no factory reset, then won't hurt to get used to this firmware I think...

Question what is the best way to unroot the rooted SM-935U. I rooted my SM-935U to restore my phone from my previews set up using titanium back up. Since I'm done restoring the phone and I would like to unroot my phone without wiping it completely so that my settings and apps are intact. Is there a way i can unroot back? i was thinking of flashing the stock SM-935U (AP_G935UUEU2APG9_CL8719017_QB10536686_REV02_user_low_ship_MULTI_CERT.tar) in the AP tab using Odin and uninstalling all the rooted apps.

Root & Unlock

I used this method (S7 Edge - AT&T) and it worked like a charm. I also used the AT&T supplied unlocked code and another carriers sim card to unlock the bootloader.

Got rid of 63 items of bloatware and life is good.

Waiting for someone to come up with a G935A custom recovery for this phone.

Whoever borrowed, or otherwise obtained the Engineering Bootloader should be congratulated.

I appreciate everyone's efforts in this area.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] BruceAbernethy:
Bootloader is Unlocked

Sorry that I was not more specific. Unlock is a separate process. Obtain the code, Insert a different carrier sim, restart phone, enter code.

Phone is permanently unlocked.

I think that I could have saved effort by doing this first, then just installing the SU Binary.

---------- Post added at 02:58 PM ---------- Previous post was at 02:55 PM ----------

I think so, however, one never really knows. Battery life seems ok. Around 50% after 18 hours. I have nothing to compare it to.

Once you have a rooted phone, you will always want one as you can do so much more with it. I eliminated 63 items of bloatware, etc and the phone works great.

engboot is even more depressing than no root, in a way. I keep checking back, and there's root, but not any root I want. Rapidly climbing temperatures and random thrashing like stutter. No thanks.

My phone is stuck at the AT&T screen please help
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] BruceAbernethy:
Phone stuck on AT&T Logo

The Boot loader is stuck in a loop.

Solution is to first press (all at once) the down volume, the power button and the home button and wait about 10 seconds until the green warning screen appears.

Then press the up volume key which brings up the Downloading Screen.

If you want to turn off the phone (while you download the appropriate files), hold (all at once) the up volume button, the power button and the home button until the recovery booting message appears in the upper left corner of the screen.

Make sure that the power cord is not connected and use the volume down key to highlight the power off at the bottom of the menu.

Press the power button to turn off the phone.

To continue, you will need to have, on your computer, the Stock Firmware for the phone as well as Samsung Odin 3. This is in a ZIP file available in this forum. (ATT_G935AUCS2APF2.zip)

Using odin and the Download screen, you can flash the stock firmware bringing your phone back to stock, and then do the re-root sequence using the engineering bootloader and the Root.bat file to install the SU binary and root the phone. You also need minimal adb fastboot installed on your computer to run the root.bat file.

Instructions for this are in this section of the discussion group on Root Available.

I have had this problem, probably because some app or apps did not properly communicate with the engineering bootloader (Think I know which ones) but Still trying to find out exactly what the problem is, however, I can now bring the phone back to where I want it is less than 1 hour using the Root method described herein and titanium backup to restore all user apps and data along with the system data concerning TouchWiz which organizes the screens. Make sure that when you backup your phone that it is on the SD card and not on the Phone card. Things seem stable at present, however, I feel real good about rebuilding the phone when the AT&T screen freezes in the future. A real pain the the keister, however I find that Root is well worth it for many reasons.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] BruceAbernethy:
Should be able to root

Using the Engineering bootloader method, you should have no problems with rooting the phone.

In case of a problem, you

should have the stock firmware available to flash and rebuild the phone.

After achieving root, you should immediately do the following: (From my notes and past brick jobs):

After Rooting the Samsung Galaxy S7 Edge do the following:

•	Lock Screen and Security: set this to allow Installation from Unknown Sources, otherwise you can do this when a nag screen comes up later on.

•	Do Not Allow any Security Policy Updates (Lock Screen and Security > Other Security Settings) – This has caused my phone to brick, multiple times, until I shut this down. (took a while to figure out that this was the real problem and was causing my phone to become a brick after it ran) The AT&T firmware updates did not cause a problem as they would not install on the rooted phone. Just took time to download, etc.

•	Install Build Prop Editor

•	Using BuildPropEditor – Make ro.secure.storage = false - This allows passwords for WIFI to be remembered.

•	Obtain Titanium Backup Pro Root apk from Google Play Store

•	Titanium Backup PRO Key from Google Play Store costs a few $ but is well worth it.

Using Titanium Backup, freeze AT&T Software Update service. (see comment above)

You should now be able to get rid of bloat and do about anything you desire. Make sure that you back up all apps and system data with Titanium Backup.

Until I found the problem (Security Policy Update) I bricked the phone about 15 times. I was able to install stock firmware, the engineering bootloader, run the root.bat file using adb and Using Titanium Backup, completely reconfigure the phone in less than 75 minutes. Mostly waiting for Titanium Backup to reload the Apps and data, then a limited amount of system data.

I have, on occasion, let the phone update the AT&T software and security policies prior to rooting the phone. The upgrades do not seem to affect the ability to root so the build and baseband versions should not matter. After rooting, the updates will cause the phone to go into a boot loop if you let them update after achieving root. It took some time for me to figure out that the Security policy update was turned on and after one arrived, the phone stopped working (bricked). Since I shut this down, I have had no problems.

All of the files and procedures for rooting can be found on XDAdevelopers.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Dzion:
Thank you for your time and information!! I've been reading everything I could. I normally don't like to ask as I find it more satisfying to dig for the answers myself. Since there is a ton of posts about this phone in general I was reading all night last night and didn't seem to find anything on the version I have on this phone APK1, well nothing definitive anyway. I appreciate it. Gonna get going on root now. :)
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] BruceAbernethy:
Here is a link to my DropBox which contains all the files you will need. Please check the XDA forums for any updates and discussion. I got all of these from the forum.

https://drive.google.com/open?id=0BzbcOyEjEvmOb3ctdVN2bTQ4UFU

Note that the exact build and baseband numbers are not exact and I cannot see any reason that they need to be.

The Odin program in the Stock Firmware folder will get you back to a workable phone, with a stock build, if you brick the thing.

I assume you know the button combinations to get to the downloading screen and the Recovery menu. If not, an XDA search will find the way to get there.

The Odin Program in the Root folder will allow you to flash the Engineering bootloader.

Move the C:\ADB files (4 of them) to your C:\windows\ directory. This will eliminate the need to add their location to the path. (files not folder)

Google installation of ADB if you have questions on this

The command >ADB devices should return the device code with the phone plugged into the computer. - Similar to this material.

C:\Root>adb devices

adb server is out of date. killing...

* daemon started successfully *

List of devices attached

904bbbc4 device

Make sure you have the Samsung drivers installed and can see the card and Phone cards in your phone before doing anything else. The ADB interface must be working. '

Make sure that USB debugging is enabled on your phone. You have to go to the System>About Device>Build Number and tap it 7 times to get the Developer options to show up.

You can then set the phone for USB debugging.

The adb server is out of date has not caused a problem.

Make sure you know how to use ODIN to flash the files.

G935A Battery

Depending on the distance from a tower, etc. battery life can be a real variable. I can go several days without the charger and depending on how much I use the phone.

The battery life seems (very subjective) much better than other phones that I have owned. Rooting with the freezing of bloat seems to improve the battery life.
