I'm not sure what happened but I ended up flashing stock PH1 firmware and successfully rerooted. Without changing anything I immediately flashed the v15 fix without the Debloat option and things are working great now except for 1 problem. I can't send texts to people that aren't already in my messages list. Like I can text anyone that already has a thread started but if I want to send one to somebody that doesn't have a tread the message sending fails..any ideas?

Try wiping cache in flashfire or from recovery.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] CrookedMosquito:
I followed this guide to rooting and everything was successful at first. I then attempted to install xposed and ran into an issue. I installed the latest version for the S7 Edge via FlashFire and after the phone rebooted it got stuck at the ATT logo. I let it set about 20-30 minutes and nada. I then attempted to boot into recovery, did a wipe and factory reset but it is still getting stuck at the ATT logo. I did notice an Error when getting into the recovery which says "dm-verity verification failed". I have also gotten into Download Mode and attempted to flash factory files via ODIN but I get an "Auth (failed)" error. My phone is currently in this state and I am trying to get it out of it, any help would be greatly appreciated. Below are the files that I have attempted to flash back to factory with the below files cause I couldn't find G935AUCS4API2, which is on it now:

G935AUCS2APF2

G935AATT2APG1

G935AUCU1APB5

The exposed version I attempted to install was x86-sdk23-arm64.zip. Pictures are available on my google drive account but not able to post. Can send if someone needs to see them. I just tried to flash again and this is the Error I am getting "FAIL! Model dismatch fail"
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] saf4xdadev:
Try a different Odin. I think the PrinceComsy Odin is only for rooting but you need to use latest Odin for flashing firmwares. I think I remember reading that somewhere. Good luck.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] CrookedMosquito:
I've used a couple different versions of ODIN.

PrinceComsy

ODIN 3.12.3

Not sure what other versions to try. I also read a thread concerning flashing the SM-G935U firmware on the G935A variant. Didn't know if that is worth trying.

---------- Post added at 02:57 PM ---------- Previous post was at 02:46 PM ----------

When i use the ODN 3.12.3 version I get the "FAIL! (Auth)".

I tried that from both methods and still nothing. I think I got it tho, I flashed stock and rooted again but before doing the v15 fix I tried a few texts, everything worked perfectly. Then flashed the v15 fix and boom! Ran into the same problem. I read on one person's post that the v15 fix is best used with PE1 rooted firmware, I'm using PH1. I've also read but not tested that once going to PH1 that downgrading isn't possible. So Im guessing that the v15 fix isn't fully compatible with PH1. Is there a way to remove the fix or am I stuck with flashing stock and rerooting AGAIN lol, and just dealing without the fix?

I know of other ways people have posted to reduce lag/heat/battery drain and how to remove the Volte icon and keep my wifi password so I think I'll just roll with them.

---------- Post added at 01:10 AM ---------- Previous post was at 01:08 AM ----------

I can 2nd this. The Prince Comsy Odin is what I have to use to ROOT but to return stock I have to use the regular version.

---------- Post added at 01:21 AM ---------- Previous post was at 01:10 AM ----------

If what I've learned is true then once your device updated to PH1 or up yoi are stuck on those versions. Your gonna need to try to find a stock 935A PH1 or PI2 firmware which I don't think is out yet. Maybe someone is willing to check out that Persian site I've heard of and get it.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] saf4xdadev:
I'm on g930a ph1 and I had a problem with texting early on and I actually fixed it by calling at&t and resetting my message center number that I messed up fooling around no relation to any rooting or anything. But I also know that clearing cache can fix it too from my old phone I once had that problem. So if you wiped cache and such with no positive effect, maybe it's time to call AT&T. But I also don't think the -v15 fix will have anything to do with breaking texting.....in fact your phone probably won't operate correctly without it unless you manually go in and tweak everything that's done in the script.

Your probably correct about not being able to go back once on ph1 and up.....but ph1 is available here on xda....at least for the G930A.....the Persian site is reputable so far if you do business with them.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
I have 930U hardware stock ROM and I want to get this sucker rooted but still use Wifi calling and VoLTE on Tmobile. Is that possible? If I flash the A rooted ROM I'll lose the ability to wifi call and voLTE on Tmobile, right?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] snovvman:
Root should not have bearing on WiFi call and VoLTE. If the current U ROM works with TMo WiFi call, rooting wont' take that away.

I get WiFi call and VoLTE on my Nexus 6, 6p, and 5x, all rooted, but haven't tested it on the Samsung platform.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] texz71:
Anyone tried rooting or updating with root already to latest PI1 and use Xposed successfully? Just want to see if I should hold onto updating nonrooted PH1 or go ahead and root while still on PH1
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] saf4xdadev:
Check CrookedMosquito's post several posts back, looks like he ran into trouble.....and isn't it PI2?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
I know root won't directly have an impact in most cases, but the root method is to flash the AT&T engineering ROM onto the U. Consequently I'm unsure if that'll prevent me from using Tmobile's Wifi calling because I'll be using an AT&T ROM on the phone.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] stew1411:
Why do you want the AT&T rom on your phone? If you have wifi calling and volte on the U firmware, you'll still have it with root. The engineering kernel doesn't turn it into an AT&T firmware, it'll still be U. Over in the U firmware thread, it's long since been discussed how to get volte working. T-mobile works out of the box in U, AT&T requires modifying a csc file. If you actually flash the AT&T firmware, you'll probably have to modify some files to get volte on t-mobile.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
Aaaaaah, now I get it - it's the engineering kernel, not a ROM. Much more sense. No one had directly addressed this, but from what you're saying it seems safe to flash the root method on the U and I'll still have all my Tmobile wifi/voLTE goodies. Thanks!
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] MehNameIsDan:
So I'm on the AT&T variant of the S7 and I tried rooting it. But now it is stuck in the AT&T logo where it vibrates once then 5 seconds later it vibrates 3 times and repeats. Is this a problem? It wont turn on and I am concerned it wont turn on again.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] stew1411:
Yes it's a kernel. Glad I could clear that up for you. When you talked about it having an AT&T firmware I was so confused at first lol.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
Thanks, I appreciate the help. There's little mention of this working on the 930U, so I wanted to make sure I had my ducks in a row. This S7 is a ***** to get solid roots for.

Actually, has anyone successfully tried updating SuperSU binaries from the Play Store yet? Curious if it hoses the phone.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] stew1411:
I wouldn't try. Last I heard we had a special version and updating would break it.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] Pseudomimic:
Your soft bricked. Going to have to flash to stock and try again. The PH1 odin files will work nicely and allow you to attempt to root again, they can be found easily on xda. You are also going to need the standard version of Odin to flash stock as the modified version found on this post doesn't work for flashing to stock, also easy to find on xda.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
Thanks for the update. Is there a way to remove it from the Play Store update page? When I have 20 updates I hate having to do them one by one to avoid SuperSu. You used to be able to use Titanium Backup for that, but pretty sure that no longer works.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] stew1411:
Open Google Play, open the app store page, hit the three buttons in the top right corner, uncheck auto update.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
Oh yeah, I do know that. But I don't use auto-update, so when I have a long list of apps I may want to manually 'update all'. If I do that, SuperSu gets swept up too.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] CrookedMosquito:
From what I understand, or have been told, there was an August update, PH1, and September update, PI2, that won't allow you to roll back. I found the PH1 firmware on the Persian site everyone has mentioned but need to create a user in order to download. I may walk down that path, download and see if I can flash it to my ATT S7 Edge. If that doesn't work then I will have to wait until the PI2 firmware is downloadable.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] saf4xdadev:
Yeah crackinx was generous enough to buy the g930a ph1 from the Persian site. That bites hard that the newer updates aren't reversible. It's just a big game.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
Am I the only one having overheating and battery drain issues with this on their 930U? I've frozen Gear VR service and it's still hardcore...
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] borxnx:
Just hit Update All then scroll down to SuperSU, click it, and hit the X to the right of the progress bar to cancel the update. You've got time.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] fbueller:
Didn't know you could do that. LOL. Thanks!
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] guzonj:
My phone is hard bricked... I can't turn my phone off now either. What do I do... I'm not holding you guys responsible, I just want my phone back...
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FilthyFord:
If your phone is "on" then it's not hard bricked. Hold volume up (either up or down i can't remember), power and home button all at the same time until it boots into recovery. Flash your stock files and try again.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] CrookedMosquito:
I went ahead and bit the bullet and bought the PI2 files for the SM-935A, ATT S7 Edge. Below are the files I downloaded:

AP_G935AUCS4API2_CL8575098_QB10880199_REV02_user_l ow_ship_MULTI_CERT.tar.rar

BL_G935AUCS4API2_CL8575098_QB10880199_REV02_user_l ow_ship_MULTI_CERT.tar.rar

CSC_ATT_G935AATT4API2_CL8575098_QB10880199_REV02_u ser_low_ship_MULTI_CERT.tar.rar

I haven't had a chance to load them on my S7 Edge to see if I can get it to boot up but will try them as soon as I get home tonight. If anyone would like these files send me a PM and I will see about loading them up on my OneDrive or GoogleDrive account.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drfsupercenter:
I clearly missed something in the past 115 pages... what's this Persian site I'm hearing about? Is somebody stealing ROMs from Samsung and selling them on the black market or something?

From my days using Motorola phones, they would usually just surface for free, they weren't being sold like that. Unless the money is to buy them from Samsung under the table?

http://dl.pars-hamrah.com/index.php?file=/Samsung Flash Files/G Series/G930A - Galaxy S7 Firmware

You'll have to change language to English and click around a bit to get to the right page but that's the site. You register and pay and they got everything up to date. Black market samsung firmwares. Legit and they work.

Using the files I downloaded above, I was able to fully restore my S7 Edge, SM-935A.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] saf4xdadev:
Did you odin all 4 files or leave out the BL per the op? And just to clarify....which odin did you use? Glad you're back in biz.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] CrookedMosquito:
I downloaded all 4 files and used the latest version of ODIN which I believe is 3.12.3. I loaded the BL file as well, didn't read the part on leaving it out. I may go ahead and try to root my device again. I mean it didn't mess up until i had loaded the Xposed framework via FlashFire.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] saf4xdadev:
Yeah....I think most of the reported problems don't start until xposed is flashed. That's why I didn't go that far, myself. Thanks for the notes though.

Just survived Hurricane Matthew on the Space Coast of Florida with a rooted S7 AT&T G930A PH1 with v15 fix. Love this stuff.

Thanks to all for making my Galaxy S7 a true lifesaver. Never lost 4g coverage the entire hurricanes passing. And 50% battery for almost 12 hours of 4g Internet and texting and photo taking and sending.

Anyone else ride out the storm on their rooted S7 device?

I'm a little too burned out plowing through the drama in the original thread to do another 100+ pages.

Besides xposed apparently breaking things what's the TL;Dr summary of what has been achieved post-root (recovery, tweaks, etc)?

Also big thanks to all involved in making this happen including the nameless soul(s) that aquired the engboot. Not all heroes wear capes. Some wear masks :-p

You can buy it here. Reputable and where a lot of others have been buying from. Probably only place for AT&T firmware. Other variants may be available other places, but for AT&T this is just about it until someone buys and posts for free download.

I'll donate if you upload to mega or somewhere so everyone has free access. Just tell me where to PayPal too when you're ready.

[AT&T Samsung Galaxy S7 Guides, News, & Discussion] saf4xdadev:

[AT&T Samsung Galaxy S7 Guides, News, & Discussion] Jraculya:
Thanks for the reply, I am trying to get back to stock AT&T for SM-G930A. I have no clue what I started at.

1. I followed the Root method found here: http://xdaforums.com/verizon-galaxy-s7/how-to/how-to-notes-root-install-xposed-unroot-t3411039

2. I then flashed EchoeRom using Flashfire, but I couldn't get it to boot.

3. I tried to flash several different versions using Odin, but none of them worked: G930AUCS2APH1, G930AUCS2APF2, G930AUCS2APH1, G930AUCS4API2. They all gave me a version mismatch error.

4. I was finally able to flash G930UUEU4API3, but I don't know why.

Please help me

hey guys, the root worked, but then everything screwed up... first, i couldn't install any apps, it showed an authentication error. then, i looked at other forums which said to remove account and clear cache in google play services. i did that, then my google play stopped working completely. while this was happening, a bunch of my apps randomly stopped working. i had enough, and i unrooted by wiping from recovery. when i got rid of SU, all the problems still persisted. can someone please help me? ( i know that i did everything right in the tutorial too...)
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] stew1411:
If you experience problems after a flash, usually a factory reset from recovery will clear things up. If not you may have a bad flash.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FilthyFord:
As [MENTION=3714404]stew1411[/MENTION] said, perform a factory reset in recovery mode. On a side note, wiping from recovery does not unroot your phone neither does removing SuperSU. If you want to unroot then you'll need to download the stock files for your device and flash them using Odin.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] Stale_Wafflz:
i got odin, all my correct files, ran odin in admin mode, got all the 4 files onto odin, plugged my phone in with download mode, but it was stuck on file transfer. then it said FAIL! (auth)

Which Odin version are you using. I haven't flanged back to stock in a while but I've read that you have to either use the modified Odin or the regular one but i can't remember which one.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] stew1411:
Download both to be sure. If one fails just use the other.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FilthyFord:

because I believe that installing SuperSU is like installing an APK, right? so when i factory reset my modded phone, it simply got rid of SuperSU, but its still the modified rom that allows it to be rooted...
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FilthyFord:
Yes it is the same as installing an app. There is not a lot of rooted things that you can do without it. I wasn't aware that you already tried the Echoe rom.
