So I've been browsing through this thread for hours but can't find the answers I'm looking for. I have the SM-G930U (unlocked variant) with firmware API3 and would like to root it. Will this method work? Also to un-root is their a stock image that is for the SM-G930U? I'm only seeing ones for carrier phones on here and when I search Google.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] beho86:
I am on the same boat. I have the G930U device. I flashed G930V firm to get the wifi-calling option. I read that I can enable the same verizon features on G930U firm, but I would need root.

Hello guys,

I have S7 SM-930R4 (US cellular locked) and I want to activate GSM module. Is it possible to flash another image (like 930F etc.) with GSM module to my phone, or any way how to activate GSM?

Thanks.

Still having problems with the G930T stuck at logo

So I'm still having problems with the G930T. I've tried unrooting, rerooting, and all.

But as soon as I flash the V15, I get the error about mounting (from lastlog) and the phone gets stuck in the boot logo for all of eternity.

It does the vibrate (pause) vibrate-vibrate-vibrate (long pause) ... rinse and repeat

Would someone be able to help? Is [MENTION=1599591]psouza4[/MENTION] still around to help debug the problem? I'm not exactly sure where to start.

I tried to return to stock with the instructions provided. I was using the 930u firmware and was going back to 930v firmware so I could trade it in for an upgrade. I have tried everything that I can think of but, I can only boot to recovery and downloader. I used odin both versions and it fails with an error. The error my phone gives is SW REV CHECK FAIL : (system)Fused 3 > Binary !

You shouldn't need to unless you're upgrading firmware too. The BL doesn't change when you root. It's an eng kernel not eng BL.

Root G930P on PJ2 firmware

Does anybody know is it possible to root G930P on PJ2 firmware by following this instruction?

I've tried several times but when I flash the root.tar for the first time my phone begins to restart every 30 seconds. And I even don't have a time to flash superSU. I know that this problem can be fixed by flashing root.bat from stock firmware (but only from PJ2 ver, lower ver can't be flashed) wrapped by tar archive. But after this fix superSU doesn't want to flash.

Is there any way to get a rooted G930P on PJ2 ver? Or maybe there is some way to downgrade a firmware because I've tried several times but unsuccessful. I've always got FAIL in Odin.

Added: some people from this thread (1, 2, ...) say that it's impossible to root G930P on PJ2 firmware. So we're gonna wait till the fix will be found
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Krieger0311:
To get my Snapchat to work, I did a factory reset, re-flashed the engineered bootloader, reloaded snapchat, and then rooted. This seemed to work but i think I may have messed a few things up that were fine before- First, any time I make a call I get "Unfortunately, IMS Service has stopped"- and I have to make the call a second time to get it to go through. Also, I cannot get bluetooth to sync with anything.

I tried to run the debloater script- the first time I rooted it worked fine. This time, flashfire runs the script fine, the phone reboots and the texts scrolls, but when the phone boots up nothing appears to be removed, and the SuperSU log has a log that says "Flashfire- SuperSU PRO required for this action". Do I really need SuperSU Pro? What did I screw up here? The IMS and bluetooth issue weren't there the first time I rooted.

Same thing for me. Hopefully can get it resolved as I'm fairly certain I'll have to unroot to get my work email on it (just got the phone yesterday).
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
You will need to use smart switch pc program to fix. See this-

Thanks for the super clutch info needed about finding PH1 over at updato.com! (that should really be stickied somewhere, like right below our PE1 build:good:) Currently downloading because I'm on PE1 and the Nougat update is looking for PH1 and can't update OTA if the phone isn't activated apparently:silly:
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Krog18:
No problem! The OP hasn't been updated in some time and the unroot firmware given will fail in odin if you originally rooted from a newer version since we can no longer roll back. 9 times out of 10 when people are having trouble unrooting the s7/e it's because they need to find a newer firmware version than what's in the OP.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] nlysurferdude03:
I have definitely not originally rooted from a newer version. It originally came with PF2, Flashed back to stock PE1, and have not made it up to PH1 yet to take the Nougat beta update lol. I can see what you mean by the mass confusion between the lack of updated posts, and a definitive guide as to which firmwares can be downgraded from and which ones can't, at least not one that I have seen.

Again, thanks for that tip that took me forever to find haha :highfive:

Weird question, I'm on the U Firmware and I was wondering could I Root, move the SBrowser 4.2.apk into the Folder (that I need Root to access) then Unroot? and keep my Data
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Public Service Announcement.........

Obviously the 'return to stock' files are no longer valid in a lot of cases....probably in all cases, especially since updates are made and new phones have newer firmwares and the OP was written many many moons ago and never updated.

So double check what your current version is in settings/about device/build number and then Google around xda and Internet to find that same version or higher, preferably same, and then use that in place of the file indicated in the OP 'return to stock' section.

SuperSU wont Install (and security warning)

I double checked USB Debug, there's no fingerprint/password, I've re downloaded all of the files just in a case, and even retried the install from Odin. Am I missing anything? Kinda frustrated and may just factory reset and give up. (I'm running Verizon S7 with September Security patch, and 6.0.1.) The message I get says "Security notice. Unauthorized actions have been detected. Restart your phone now." Fast help would be greatly appreciated, kinda stressed out about it D;
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Did you try the other Odin?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
I got the Korean INI error thing.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
So did you get the engboot kernel to load? Do you have root?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
Quite new to this, not sure exactly what this is/how to tell. Odin went through and everything went perfectly on that end. Once I went through all of Odin and my phone rebooted, I checked the USB Debugger and it was on. I then moved to SuperSU and tried the root. It failed (my phone never rebooted either) and I've been getting Security notices since.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Sounds like the kernel loaded correctly. Next step is root.bat but you need the adb to be in path or you can just place all the files in same folder and run root.bat from there. Also put the folder near c: or make sure folder names are one word. Security thing is OK for now and will be fixed with the v15 fix flash. Also check in settings/developer options/usb configurations/ is set to mtp and not to charging .
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
By APB files in path do you mean the APB files I have in my C drive currently? Or do I have to redo the setup that I have in my downloads.? Also, should I combine the APB files with the SuperSU ones? (Sorry for my ignorance.)
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
It's adb not apb.....and no if it's installed on c drive it should work so run root.bat again. Sometimes it takes two times. Putting adb files in with root.bat files all in one folder works too if problems getting root.bat to see adb.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
Everything was put in the same C://adb (sorry about the typo).

When I doubleclicked root.bat I got this

C:\adb>adb wait-for-device

C:\adb>adb shell mount -o rw,remount /system

C:\adb>adb shell mount -o rw,remount rootfs /

C:\adb>adb shell rm /data/su.img 1>NUL

C:\adb>adb shell mv /data/su.img /data/su_old.img 1>NUL

C:\adb>adb shell rm /data/su_old.img 1>NUL

C:\adb>adb push SuperSU-v2.76.img /data/su.img

When I ran as admin it went right through but nothing happened after at all.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Sorry not on my computer and can't remember exactly but your sure the adb is running and the supersu zip file is unzipped and all in the same directory?

Also double check the engboot kernel did in fact load correctly. Do you have the unlocked padlock when you boot?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
I do have the unlocked padlock, and both SuperSU (5total files) and adb (4 files) are all under C://adb. I checked in task manager and adb was running. I even closed it with task manager and ran the root.bat again, and the root.bat took a moment to reopen it, but still stopped at the C:\adb>adb push SuperSU-v2.76.img /data/su.img

Didn't notice earlier, but I am set to MTP.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
That's a mystery?? Everything you have looks correct. Recheck your connection. You're doing it right.....
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
Just switched around my USB ports and same CMD dialog every time. I searched up responses a bit before I decided to post and read things about Firmware. I couldn't see anything about Firmware in my About Phone so I ignored it. Could that be my problem?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
What version do you have? But no probably not.

Check settings/security/unknown sources set to on. You've done everything by the book perfect. It really should work. The kernel is what would not load if firmware was the issue.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
Did the unknown sources and still same prompt. Also, I think it's just SM-G930V and 6.0.1 right? (Not sure if that's what you were looking for)

Don't know if this is relevant but it says Kernal Version 3.18.20-eng

Also on the top bar (where wifi and things are) there's a strange oval and it says "Vo))"
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
That's all perfect the way is correct. Are you sure your not rooted? Build number under about phone is your firmware and last three letters/numbers is what will indicate basically update version.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
The tutorial said you'll know when your phone reboots, and mine never has. Though I am getting the security warning constantly. Is there any other way to check if I'm rooted?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Basically do you see supersu in your app section. Rootcheck from playstore. Also try to get flashfire from playstore you'll need that to load the v15 fix that will fix all the stuff your seeing. You'll also need titanium backup to stop the securitylogagent from sending the security message you keep seeing.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
Root check came out negative, do you think there's anything I might have looked over? Something that you would know but I wouldn't (since I'm new).

https://gyazo.com/35de27c3e3c8124f6af0fd2b0d866956
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Maybe.......try putting the supersu files into the adb directory . Basically get rid of root directory and have all files in same directory. That will work. I didn't understand what you had before but the picture of your files did it. By the way what version of Windows or Linux are you running.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
I'm sorry I'm so retarded, so I copied the command line to put it into google and happened to leave the command box open for longer than usual. It took about 4 minutes of the same line "C:\adb>adb push SuperSU-v2.76.img /data/su.img" and then suddenly it instantly went and my phone restarted. I feel really dumb.

Nevermind. I had to grant access.

---------- Post added at 03:27 PM ---------- Previous post was at 03:17 PM ----------

Err, sorry to bother again, but do I download the one that is for PE1 since I have Verizon, or just the top two? (I checked and I'm on PH1, is that a problem?)
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
Search for Krog18 post about which v15 file to use because it's not the pe1 anymore but I don't remember which one.

Yeah I should have realized you didn't do that permission thing too. I was walking my dog the whole time and I had to keep looking for shade to see the screen and also keeping my dog in line. It was something that just take for granted when doing these things....always forget the simple or obvious things.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
I cant thank you enough for putting up with my stupidity. I looked a lot into it beforehand and everyone's went by really fast, I was really nervous after all. Once it took too long I'd just close it. I just should have let it run it's course.

About the Krog post, I cant find anything relating to the updates on PH1. (I found it, it says I could just use the normal software, thanks again!)
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
No problem at all. I'm retired mechanical engineer so I love problem solving and miss. I thought I had asked if you were letting it run long enough but I guess not.

If you want to insure a problem free phone I would recommend AGAINST the debloat and also AGAINST xposed.

But you could try one of the custom roms, either stang5litre or Echoe, since they have had good results. As long as you carefully read the entire posts......like you did.....you should be fine.

---------- Post added at 03:52 PM ---------- Previous post was at 03:48 PM ----------

Yeah that's right.....the v15 for any samsung galaxy is the one.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
Err, I already did the two, is there any way to uninstall them and get the custom ones?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
You did what two? Don't uninstall anything yet.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Sayunoi:
The V15 and Debloater.

All of the problems went away really, I'm just having major lag problems. I'd still like a custom patch though.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] saf4xdadev:
That's OK with debloater as long as it installed without issue. Don't try any uninstall it's all fine. I would not use Xposed though.

As for the two different custom roms, just read their threads and OP instructions and determine which one would best work for you.

Yep, the one thing I took away from all this when I started flashing and customizing back in 08 on the HTC G1, was read, read, read, and read some more before you do anything. I learned my lesson staying up all night a few times just trying to find the right command to get the phone out of the non booting state mess I put it in many many times. Those were the good ole days haha. Now everything is "1 click" here and "1 click" there, you just gotta make sure you're clicking the right one lol :silly::good:

However after learning all that and knowing what I know now, once I got this S7 coming from the Note 7 about a month ago or so, I failed to look at the last time the OP was updated, and just assumed the post was relevant, as I only saw the PE1 file to flash back to stock. Knowing I was on PF2, I could safely downgrade (after much reading) to the PE1. I only had the thought about updating to PH1 so that the Nougat update would take, as it wouldn't flash from PE1. Then I came across that wonderful post to find the PH1 firmware download, and ever since then it's been smooth sailing:good:

The only thing I've learned so far from this phone, is about removing the google account before wiping the device, to avoid the FRP and lockout for 72 hours:mad::eek:

Long story short, never assume something, read, read, and read some more and double/triple check the steps you are about to take to avoid a soft/hard brick:good::highfive:

I have the Snapdragon unlocked version of the phone and rooted it a couple months ago. I never realized until recently that the WiFi calling/text doesn't work until I needed it. I found a solution of unrooting (and leaving it unrooted) or rooting again a slightly different way. the only propblem with unrooting is in the OP I do not see firmware download for my version. I am using it on verizon but never had that version of firmware installed. any help or suggestions would be appreciated.
