Getting Odin to see phone

Hi there, I have rooted and rom hopped a few phones over the last several years, and had resigned myself to the fact that I (like many others) were just basically hosed with the new S7edge as far as root is concerned. Having read through almost ever post in this 150+ page thread, it looks like I have about a 50% chance of getting root if I follow directions.... If.

I have downloaded the requisite files, and would like to give it a shot, but I am hung on the first step believe it or not..... I launch Odin (prince comsy), load S7edge_qualcomm.tar in to the AP slot in Odin, put my phone into download mode, connect the phone and nothing..... I do not get a green COM port light bar, which tells me that there is no communication between the phone and my PC. USB debugging is on.

Since it has been nearly 2 years now since I have rooted a phone, what is it that I am doing wrong? I feel like I have the steps wired, having read them no fewer than 36 times......

My baseband is: G935STUVS4BQC1

Any tips?

Thanks.!

Have you tried a different cord?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Team Scream:
Really good question, but yes, I have tried 3 different cables so far.

You need to give permissions thru adb. Been awhile since I did it on mm but it's the same. Can't quite remember what I had to do but if you open a command prompt in the adb folder and type devices your phone should come up as a 8 or 9 digit number. I would start there. Search the adb forum. But I do know if you don't allow your pc to connect to the phone things won't work. Also do you have your USB settings on mtp. Down farther Past USB debugging look for media transfer protocol and select that
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] freeop:
As Jruka just mentioned, you have to get the phone and computer talking together. I believe the command you need to use is (at the command prompt) "adb devices". I have done this every time and the adb will start a service and then give you the nine digit of the device connected to your phone. And not until the service is started with the phone will you be able to connect.

Hope this helps...

Sounds to me like you don't have the Samsung driver installed?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Araltd:
You've got a much better than 50% shot of getting root...I have no clue where you got that number or idea from? :confused: I'm not sure "which" S7E you've got (from what carrier) but the only people who have reported having issues seems to be sprint (for the most part) and AFAIK the sprint folks have gotten it ironed out in the sprint sub-forum? The rest of us have successfully rooted with varying results of performance issues.

Right now, you're computer and phone are NOT communicating - that's what you are stuck on. Download and install the Samsung drivers to your pc first (use google the samsung drivers are everywhere and easy to find)... connect your phone in normal mode and watch the screen (it might be a good idea to set the timeout to max 10min until you get this situated) when you connect the phone AFTER you've installed the samsung drivers you should get a pop up on the computer asking what to do with the phone (this is AFTER THE DRIVERS HAVE SUCCESSFULLY INSTALLED FOR YOUR DEVICE)

Once you see that on the PC- look at the phone and ALLOW connection on the phone and verify that you can see the phone (open my computer and you should see your phone, open it and you should see internal storage and card storage IF you have a card installed in the phone)

AFTER you've got that going, make sure you have the ADB drivers installed and working... (THIS IS AFTER YOU GET THE BASICS DOWN OF HAVING THE PHONE TALK TO THE PC) Install the ADB drivers, open the command prompt and type ADB DEVICES, of course you should have your phone connected and adb debugging enabled. At this point look at your phone screen and ALLOW CONNECTION AND CLICK REMEMBER OR ALWAYS or whatever the check box says. At this point you should have your phone talking to your computer in normal mode and adb mode.

Now, after all that, let me be honest - and this is going to sound rude but I can't help it... If you are stuck on the first step of getting your phone talking to your computer - maybe this root is not for you. In my opinion, this rooting method is absolutely for advanced users. IT IS NOT LIKE A ROOT ON A BOOTLOADER UNLOCKED DEVICE. So it's NOT going to perform the way you may have been used to on a previous device. Not trying to be rude in anyway - I've layed out the instructions above if you want to continue, but you should consider all options and outcomes. PROCEED WITH CAUTION. :good:

Thank you sir !!

Thank you sir. My device is an S7 Edge SM-G935T on T-Mobile with Baseband G935STUVS4BQC1

Actually, my phone and PC communicate perfectly. I can drag and drop, get photos, documents etc. to and from my phone in explorer no problem (Win7)

^^ This may actually be the problem. I am sitting down in front of my computer right now and will seek out the ADB drivers and report back after installation, and having followed the steps you outline. Thank you!

No offense taken brother, I know that this is nothing like rooting and rom hopping my older devices. I am the kind of person that has so many different things going on all the time that I tend to drive all references out of my short term memory, unless I am actively working that "thing" on a regular basis. Such is the case with rooting. As I mentioned in an earlier post, I have not rooted or flashed a rom in close to 2 years since I have been on the S7 for obvious reasons, so that is why I am floundering right now. Once I connect the dots, I will be able to move through the maze rather skillfully I am sure, but since I am also the cautious type, I thought it better to ask questions, rather than brick my phone and come in here in a panic looking for help after the fact.

Thank you very much! I will report back soon with progress.....or lack thereof.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Araltd:
You should NOT need ADB or anything special besides samsung drivers to flash with odin. When your phone is in download mode, and you connect to your PC, and you don't see proper com box high lighted in odin - you have some kind of communication error between pc and phone. That absolutely needs to be resolved before proceeding.

This pic is just from google'ing - just using as example of what you should see.

THIS IS GOOD, you want to see something like this. :good:

Good luck... don't forget to take a moment to hit the thanks button for all those people on the first page. :) this root would not be possible without them.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] xDark_:
So is there absolutely no hope of getting Magisk or even PHH'S SuperSU working on this root? SuperSU's new Chinese overlords just pushed out a super shady update that not only bootlooped phones but now asks for very intrusive permissions along with adding a Clean Master clone to their arsenal of apps (presumably it's going to be installed alongside SuperSU in future updates). This really is unacceptable in my opinion and I want to get the hell away from them, as far as possible. Or at least be able to use SSU 2.76. Any chance this could be done?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] jruka:
I has ssu try to update yesterday and I just noticed I just lost root ......
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] freeop:
Yep had the same thing happen to me. I went from SuperUser 2.79 to 2.80 and completely lost all root. Tried everything that I could think of to see what the problem was but finally figured out that 2.80 will not work, at least for me.

I ended up using the [MENTION=5149713]Quickvic30[/MENTION] root.bat again and everything is back to normal. Guess I won't be updating SuperUser for now.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] jshamlet:
SuperSU was updated again last night to fix the lost root issue. Not sure what was going on, but it seems that it wasn't specific to any device.

On the other hand, it's an app that you should be able to safely turn auto-updates OFF for. The only reason to get a newer version is to support a newer Android version unless you have a specific problem.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] jruka:
I actually run mm. I just read the 7.0 forums so when I decide to switch I know what issues to expect. The ssu update did hit everything though.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] freeop:
Yep, I tried the newest version, 2.82 I believe, and installed just fine. Checked with Root Checker and said I had root. Was pretty happy, BUT when SuperSU notified me to update the binaries and rebooted, lost root again. So back to 2.79 and sticking with that one. AND will be making sure that app does not update any longer.

Thanks for your comments, [MENTION=6005385]jshamlet[/MENTION] :)

Hi, quick question. I haven't been on this thread in a while, but ever since all of the companies allowed unlimited users to use hotspots, I am tempted to go back to stock. However, I am on AT&T and have yet to be able to find a HOME_CSC file for the s7 Edge on AT&T. Does anyone have this file so that I can do this without having to go through the annoying task of setting my phone up from scratch? I have checked all of the places I can think of to no avail. Thank you in advance.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] BookCase:
Would love to know how to update SuperSU to v2.82 and the SuperSU binary without breaking root.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] theeunforgiven:
Lots of lag

Yes I read the first post, sometimes there's a huge spike of lag when switching apps or going to the home screen, when it's the worst is when I get a phone call or hook up the charger, if I were to unroot will the lag go away? Since xposed isn't ready for the s7, I really don't see any point in being rooted anymore

Ps only reason I rooted was to remove bloatware and modify some apps

Samsung SM-G935A AT&T 7.0 Nougat

I am trying to root my phone for the first time and I have ran into a few problems.

I am having problems with the flash, I used S7edge_qualcomm.tar on ODIN3 and I get FAILED! SHA256

I have also tried the patched version of ODIN3 and I get the red bar saying it failed.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] 124chase:
Do you have a US carrier version of an S7 edge running Nougat?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Lenny562:
Yes, I have the SM-G935A from AT&T
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Lenny562:
I finally got Odin3 to pass and I also ran the root.bat and after my phone rebooted it installed SuperSU on my phone.

But, when I open Kernal Auditor it says I have no root.

Also when i open up SuperSU it wants me to disable KNOX but it doesnt work.

[MENTION=1949695]jrkruse[/MENTION] has created and released a new root.bat with supersu v2.82 which resolves some issues and retains root access, this is quoted from his custom rom thread. All appropriate links are on the first page. I would like to ask people to please take a moment and hit the thanks button for these guys - the work they put in to creating and releasing these options for the public is the only reason rooting this locked device is available to us all. If you have already thanked them - find another post from them and hit the thanks button again. It's free for you and mean's a lot to the people releasing these options for everyone. It will only take a minute of your time. THANK YOU!

**EDIT: [MENTION=1949695]jrkruse[/MENTION]

on 5/29/17 has created a new

ROOT.BAT including SuperSU v2.82, it has been outlined in this post #480 of his custom rom thread. As always, please take a moment to hit the thanks button! Without the work of these amazing dev's we would NOT have root PERIOD! It is free for you, and mean's a lot to everyone involved in bringing these releases to you the public!!!

Here is latest root zip with SuperSU 2.82 (5/29/2017)

Can we use magisk with this root? Instead of supersu?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Okijaamaka:
please after the root, is there any way to sim unlock the phone to any carrier
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] freeop:
As far as I have found out from searching and trying to answer this same question, is basically if you have a US Version of the Samsung Galaxy S7/S7 Edge we are out of luck. All the GREAT mods and fun things that can be done with the S7 is associated with the EXYNOS version of the cpu. If you have that version of the phone you are in luck. But like me and many others on this thread, we have the SnapDragon version of the cpu and we are limited to using what we have here with this procedure.

If you read thru some of these posts and thru XDA-Developers, I believe you can do this with the U version of the firmware. It is possible to flash your phone from the ATT, T-Mobiel, Sprint, etc the the U(nlocked) version of this phone. I haven't tried it, but I have read that many people have had great success with unlocking their SIMs. Good Luck...
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Okijaamaka:
thank you
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Araltd:
sim unlocking G935T is done thru app and tmobile server only at this time, and all aftermarket unlock services/servers are down globally. AFAIK the only way currently is directly thru tmobile. sorry - good luck.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Okijaamaka:
what about the U version of the firmware?

someone said it's working for unlock

Phone seems really slow after root

Root method worked but now my phone is really sluggish.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] notobsessivejustcurious:
The very first initial boot up is laggy, yes. But give it a few. let super Su do it's thing, then it will catch up.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] luis_o_98:
no data

firsit off im going to say im not the best at this and any help is greatly appreciated. that being said i followed the instructions and everything seems to work fine but i get no cell service or data. the phone shows signal and i can dial but when it connects i get a message saying i dialed the wrong number no matter what i dail
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] djxenex:
Your right it seems to be picking up. I installed the kernel adiutor and set to on demand. it seemed to help right away.

There are some strange icons on my top bar now though.

was going to post an image but the forum wont let me since i am a new user
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] 93starletgt:
"Rooted" using this method, the black boot screen showed an open lock with a "custom" message. The phone got really hot and it was extremely laggy. But every app that needed root permissions displayed a message saying there was no root. Tried to update the Supersu bynaries and it failed. Used it for a whole day and the lag only got worse. Then unrooted using the same method, but the "custom" message at boot didn't go away and the phone was still slow and running hot. Installed original firmware via Odin and it is now finally running normally (although the phone was Sim unlocked via the TMobile app and now it re-locked itself). The two remaining issues after this: it fails to check for systems updates (instead of saying it's up to date) and it fails to Sim unlock via the app.

Do you guys think we will have a better rooting method in a near future? I'm about to go back to my Note 5.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] djxenex:
for me the second part of the process the root.bat file i needed to change my usb setting from file transfer to software installation. the first attempt i tried without doing this and root did not work.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] 93starletgt:
Right. But even if it works I prefer to use it without root. What's the point of having a high end device if it runs as slow as an S4 nowadays, hot and with terrible battery life? I tried playing with the CPU governors, it helped a bit but it still runs terrible. Personally, I think this rooting method isn't worth it.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] djxenex:
mine was the same

I rebooted into recovery cleared cache, and I installed the kernel adiutor and set to on demand. it seemed to help right away.

now it seems good so far
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] freeop:
I too had used the original root.bat and had a terrible experience with this root method. Until I was reading through the replies and found on page 69, under post #688 a root.bat that has so much better performance and no heat/lag and with it I am getting from 36 to 48 hours battery time. With only the root.bat and NO kernel adiutor or LSpeed installed.

You should give it a try. The post is by [MENTION=5149713]Quickvic30[/MENTION] and I really think you will be pleased with it.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] jshamlet:
This root seems to vary widely in performance for unknown reasons. It really is YMMV. The heat and lag, however, stem from the engineering kernel, not SuperSU. As long as you have that kernel, it will run like that. The only way to fix the issue is to reflash stock firmware. Note, you will have to reboot a couple of times after reflashing stock to lose the custom message at boot.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] 93starletgt:
Thank you. I tried it as soon as you wrote this message. Root works well. The phone still gets warm and still lags (Although considerably less). Had a proboem with the samsung keyboard ignoring what I was writing leaving a blank input, but solved it by downloading the latest Samsung Keyboard app from Apk Mirror. Also, when rebooting (or starting from shut down) the phone freezes at the white T-Mobile screen and restarts itself, it does this exactly 3 times until it finally boots. This happens every single time the phone starts. Battery life at idle is still mediocre. Followed instructions word for word. I'm in the BQE1 firmware (7.0). Installed kernel auditor and it lags less. Still considering going back to my Note 5. :(
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Krog18:
To fix that 3x reboot, using a root explorer, go to /data/s7startup and delete any files in there EXCEPT master.sh and s7cpusettings.sh

There's probably a leftover s7updateothersxml and/or s7updatebuildprop that would cause this.

[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Quickvic30:
The phone will lag upon reboot for a couple mins until either you open a app that has root or just open the super su app itself. Even after it will lag for a couple mins, it best just to boot and let it sit for a couple mins before you go about your business. Have any of you guys tried the build prop edits I posted shortly after the root.bat post? The build prop edits help quite a bit. That's good its running better anyways. you can try messing with it with kernel auditor or and kernel app and see if maybe that helps, like I've said many times before....every CPU is different......just like humans lol.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] 4DGeorge:
If we merely apply your new root.bat on top of our existing rooted device, will that suffice?

Or do we need to go through the full procedure again of flashing the boot.tar via ODIN before using your newer root.bat?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Okijaamaka:
i just did and they are now asking for network sim lock?

could there be any progress?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Quickvic30:
Nope dirty flash away! I would flash it if I noticed the phone getting laggy or anything like that. I like to remove the super su app though BUT before you do that go into settings of the app and do a full unroot and choose normal recovery option, phone will unroot and reboot on its own, once booted let it sit for a min or 2 and then reflash root.bat. Ive dirty flashed this root.bat file so many times its not even funny lol.

Everytime I long press on my apps while on home screen, Touchwiz force stops. Any help? Thanks in advance.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] Araltd:
I completely agree. The backup available to everyone is so basic it really is pathetic. As advanced users maybe we expect more? I can only guess? But I agree wholeheartedly. Samsung and/or Google should supply a way to "snap shot" backup a device without hacking or modding your device(s). Just restoring apps can be done with a pencil and paper or a good memory....
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] 93starletgt:
I give up. I've done everything that has been suggested in this thread (Build props, played with CPU governors, used different root batch files, tried it in different firmwares, and more). Everything just "helps" a little bit, but the phone is always warm as soon as I use it (even just by browsing through emails in Gmail), feels terrible and battery life sucks. I still think it's not worth having a high end device running like an old S4 mini. I just purchased the Canadian S7 Edge G935-W8 on eBay. I'm so looking forward to install TWRP and try different roms. My G935T will be on Craigslist soon. Thanks for all the help. :)
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] cjlopez213:
Everything works fine for me thank you so much! Thank you everyone who gave tips and tweak. My only problem is with Swiftkey that I thought maybe someone has fixed. It lags on me really badly. I can type a sentence and look at the keyboard filling out what I typed very slowly. Does anyone know how to fix this?
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] 93starletgt:
There are some tweaks that "help" with the problems, but they do just that. Your phone will never be perfect if you root it using this method.
[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] cjlopez213:
Really? Because it seems to be running perfectly for me. I just installed the newest version of Samsung Keyboard from apk mirror and the lag has completely disappeared.
