I don't see OEM unlock in Developer Options

My Galaxy S7 (SM-G9300) is up-to-date with Nougat firmware. I can't fine OEM unlock feature in Developer Options. I try to root with this help but it didn't succeed. Please help me. Thank you.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
No there is currently no way to install a custom recovery on your model phone. The Bootloader is locked. And with the AZ (Cricket) model, rooting seems to cause boot loops. But you're welcome to try.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] lylehang:
nobody creats cook rom for G9300??????

---------- Post added at 10:45 AM ---------- Previous post was at 10:43 AM ----------

You update by OTA or ODIN?
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] bluesky58:
Via Odin because I was using a custom rom before flashing.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
It's almost at the top of the Developers Options, but if you have a modified ROM it's anyone's guess if the option is there or not... Depending on how the ROM was built, and built off of what firmware.

You may be stuck and have to reflashing back to a factory firmware for the 9300, and turn of OEM Unlock... Then flash any custom ROMs.

What errors are you getting now when you try to boot your phone. And/or what errors did Odin give you when flashing the update?

SM-g930U unlocked TWRP yes or no?

I have an unlocked and unbranded SM-G930U (just bought at Best Buy FWIW) S7 (not Edge). Can I install and use TWRP or not? Can I root or not?

The phone has been charged up but not powered up. Obviously I want to do a NAND backup before I root. Which means I need TWRP.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
Root is possible on certain firmwares. TWRP isn't because of our locked bootloaders. I'd recommend you get a different phone if you want anything more than basic system root functionality.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
All I need root for is Titanium, Root Check, and (if possible) Viper, not custom ROM's.

An unbranded, unlocked SM-G930U still has a locked bootloader??? I thought that was something VZW did to their phones (like my failing S5).
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
All Snapdragon S7's have a locked bootloaders aside from the Chinese ones. If you have a Exynos S7 you'll be good to go with rooting and TWRP but all U.S S7's including the U variant have locked bootloaders. Fortunately the root method allows us to get titanium backup and Viper4Android to work. Titanium backup works with no tweaking required and you need to flash the universal version of V4A Via Flashfire to get Viper to work. I can.confirm the U firmware is rootable.

Note: V4A has this weird issue with playing volume at full blast even while muted on the S7's, just a warning.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
OK, you're saying I can root, as I rooted my S5, even though I never got TWRP functioning.. The one loose end is backing up the phone (again, never even been powered up, just charged). Life will go one without Viper. :)

"All" I need are links to deal with backing up (NAND - if possible) and rooting. Google keeps pointing me to non-U phones (which is how I found this thread).
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
Nope a normal root method won't work here. The root method for the S7 involves flashing a modded boot image and then running a script in ADB to root. If you tell me which version your phone is on and which carrier you plan on using it with it can direct you to the root method applicable in your case.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
Thanks for your patience and help. The model: SMG930UZKAX The provider in the US: VZW (already a customer - will change phones online) but... I want to go with a dual SIM while in Europe. Probably the provider will be Vodafone or maybe T-Mobile. It'll be at least before I know which provider I'll use.

I've used Odin in the past and rooted a few phones, some I'm not a total newb, but basically I'm better at "following recipes" than using in-depth knowledge. And a tickler about wanting to back up the phone before making major changes. :)
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
I'll try to put together a root method for you, give me a bit and I'll try it to have it to you ASAP.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
Good on ya, and a case of virtual beer to go with it!

[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
Great thanks!

Before I commit myself with this phone... I can take it back to Best Buy ("never used" can't hurt) and go with something else. Pixel XL looks attractive, but $800 - don't think so. HTC 10 looks good, too, but I don't think the bootloader can be unlocked. Motorola's Z (which seems to be way down on the list compared to the other phones mentioned) can be unlocked but won't work with VZW (dealbreaker). LG... meh, not a fan. Thoughts?
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
My biggest recommendation would be the Google Pixel. It has a ton of development and roms available. If not I'd recommend the HTC 10. If you never want a custom ROM or systemless root don't bother returning it, it works great.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
My biggest stumbling point is (if I have it right) there's no way to do a NAND backup before ...um... getting creative with the phone. Past that, all I need is support for Titanium and Viper (and I heard you about the volume issue). Being able to have dual SIM's in Europe is a welcome plus.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
Yup the S7 doesn't root easily. Be careful.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
Just to be sure I have this right: no backup possible?
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
Nope. With odin you can keep some of your data using the home_csc instead of just the csc, and backup through apps like Titanium Backup work, but aside from that, nope. It's easy to get out of a bootloop though.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
Oh jeeze... total brain burp on my part. I missed that this is for the Edge SMG93

5

U, not the non-Edge SM93

0

U. I'll be very surprised if the rooting process is the same for Edge and non-Edge S7's.

---------- Post added at 06:37 PM ---------- Previous post was at 06:32 PM ----------

OK, once I move to root and effectively FDR the phone back to almost bare metal, I'm on my own. Oh boy, swell...

BTW, pls see my note about the SMG935U. I think I'm back to square 1. I may have to look at the Pixel after all... gngh...
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
Nope you can root the g930u. Hang tight.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
Trying to avoid brain burps, I can use the 935 process on the 930?
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
As long as you have the matching base firmware and engineer boot image that matches the phone, the rest of the process is the same... I can't think of any steps that are different.

And not all is Lost either with rooting. It's not like when you load a custom recovery and then there is a trip counter for how many unauthorized OSes are loaded. As long as nothing physical is done, not forgetting to enable OEM Unlock, the phones can be easily repaired through Odin. Worse case you have to flash back to stock and start all over (and been there done that).

Most part if you flash back to the stock OS, clear all the caches, and reboot a few times... No one could really tell the phone has been rooted. If you decide to pass it along to a friend/family member or something
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
OK, got it. Great thanks!
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
I'm rooted and debloated. Yea!

As I woke up the phone (remember I began at "not even powered up", someone (Samsung??? no SIM in the phone, just WiFi) tried to push an OTA update. As I wasn't rooted I said "hell no!" Surprise! The OTA push won't go away. Since the update proclaims security enhancements, why do I think it will very nicely de-root me or brick me or otherwise [/expletive deleted] with the phone for my daring to tamper with their... make that my phone. Recommendations? Hey, maybe they're going to leave root, etc. alone and push Nougat at me. Nah...
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
Don't take an OTA, it will brick your device. Uninstall the update packgages, remove the update file from data/fota, and the phone shouldn't notify you to update anymore. I only left the following packages with update in the title: ConfigUpdater, KnoxUpdateAgent, and I froze SecurityPolicyUpdates.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
OK, I thought the OTA would bring phone death - we're agreed. You removed or froze anything that says update (and isn't some simple game app or whatever) except for the names you listed? Great! I went through this with the S5.

One big operational surprise: I need a nano-SIM, not the present micro-SIM. ARGH!!! Is VZW likely to say "no way!" when they see the open padlock and CUSTOM? Possible workarounds if they do? This makes me wish I had activated the phone first. Oh well, coulda, woulda, shoulda...
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
Well for a SIM that should be something you can buy and install, a Verizon tech would never need to bother with your phone... Unless you asked them to activate the phone for you.

Though once the phone is rooted, it's likely the activation services no longer work (as with most roots they are part of what's disabled - I have Sprint and it's that way).

A good tech would probably ask or make note of it, most sales people would.probsbly just go through the motions and never notice. But if I were you and needed to activate a new SIM, I would go back to stock and go from there.

I screwed up activation through one of many rebuilds of my phone. I tried unfreezing apps to get it to work, after I had rooted. Spent a couple of hours and ended up.vlowing the phone away with Odin back to stock firmware, and went through activating first... Then rooting.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] :
They won't activate it for you. You'd need to go to stock and activate, then root afterwards.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
I can activate a SIM online. I wanted simply move the S5's SIM to the S7 and register the new IMEI, etc. (which can be done on a VZW site). OK, I'll start with "please make this a nanoSIM" and see where that goes. At least I have TI running, to make recovery from going to stock and back to root much easier.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
Haha oh yeah that's good to know. Everyone has got to be different, it's so confusing! Happy activating!

Coming from a AT you're probably in the same boat as a lot ofnus. The 5 was so easy to root, modify, and have fun with. That's why I grabbed the 7 without a second thought.

As this phone situation won't stop me from buying another Samsung in time, I am educated now to probably get a different model that allows rooting as easy as having Odin and a custom recovery.

But enjoy... At least we can still root and the phone is still fun with customizing!
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
I'm going down the path you're describing. The S5 is fading fast (screen issues, battery issues, and some other aggro hovering in the background - anyway far too expensive to repair the phone). Like you, I thought the S7, and particularly the unlocked S7, would be far easier to work with. (The S5 is a VZW-branded phone) Wrong... I'm not drawn to serious hacking, although a few good tweaks are always welcome. But still being denied TWRP, for example, is... Argh!!!

I looked brieflly at Moto stuff, but, if I read their docs right, totally unlocking the phone is possible. But then won't work with VZW. Much as I hate their messing with my phone, I need their coverage. ATT, T-Mobile etc. just don't get where I must have connectivity. The other guys do pretty well, but places like the I'm Lost, NC just aren't covered, VZW at least has voice there, if not full data.

I'll update the thread once I have the phone on the air. I think, to save time, I'll unroot after backing up everything on a 128G SD that will go in the phone later anyway.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
I've lost root! SuperSu granted su to Chainfire and Root Checker said the phone's rooted. I just tried to run TI (a day? after rooting) and it said "not rooted". I went back to Root Checker Pro and it now says "not rooted", too. (All of the code segments are marked up and colored to match Root Checker's output)

It seems that su never got into, or was removed from /system/bin which is rather odd(!). After rooting I ran the "debloating+fix" script for a VZW user. I suppose the script got me, or installing my usual apps from Play Store did some damage. I'd bet more on the script than the Play Store apps, all of which are on my rooted S5.

I guess plan A is to return to stock, activate the phone, then try to root again. But it's very odd that Chainfire was granted su, Root Checker ran, and then... crickets.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
Actually nice had this happen a few times rooting. Let's get back to basics. Currently which version of SuperSO do you have installed?

You can try this, go into the settings within SuowrSU. Scroll down to almost the bottom and select "Reinstall". Phone should reboot, if not manually reboot. Go into Play store and install SuperSU again. See if that fixes it?

If not, try doing the "Reinstall" again. This time do not install from Playstore. Go back to the rooting instructions and reOdin the Engineering Boot image, and rerun the script to root. See if that fixes it.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
2.79

Well, this isn't good. SuperSu said it was uninstalling itself (good), but it was still in Apps, on my "internals" screen, and it ran when tapped (bad). I rebooted and it's still there(!). I dragged the Apps icon to Uninstall at the top of the current page, and went through another uninstall. OK, finally gone (good, I guess). It reinstalled as expected. FlashFire and Check Root still say "not rooted" (very bad).

OK, I'll give it a try.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
If when you go back into SuperSU did it still ask for binaries to be updated? If it does it's a sign that SuerSU is not fully there correctly (and thus the results you have).

If none of the apps say you are rooted, but then you go into SuperSU it doesn't ask to update binaries... Go and switch SuperSU setting from PROMPT to GRANT and see if they say if you have root then.

Also, had to look up in my notes, make sure that SU is enabled during boot. Reboot if you had to enable it, see if that changes anything.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
The phone is rooted again. There is an oddity with SuperSu. The root.bat script tries to install SU 2.76 but fails (maybe with a "wrong version" message, but it didn't last long enough to really comprehend). SU 2.79 is still around and working. Anything I use that requires su (FX, FlashFire, Root Checker, etc.) asks for su and doesn't ask again after it's granted. TI is currently backing up everything in sight, and doing it to the SD. Woohoo!

The next challenge is to get the phone activated...
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
Oh sounds like you might be using an older root.bat then. Check out this one provided by [MENTION=1937421]YMN[/MENTION]DZL that uses SuperSU V2.79 . If you have to run through the root process again

[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] RBEmerson:
Thanks! If I have to unroot to get a SIM out of VZW, I'll use that as part of re-rooting. The first TI backup pass "b/u user+system apps & versions" worked and "redo b/u for moded data" is running now. :good::good:

[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] thescorpion420:
Hardware wise, yes but the bootloader is locked on our US snapdragon models.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] Chillstice:
I'm sorry I'm not too familiar with the consequences of having a locked bootloader. Would this mean that it wouldn't flash successfully/ won't work properly? I just need it to flash a zip on a boot-looping phone.

Later I'm planning on using it for backups.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] thescorpion420:

Rooting is pretty simple but unlocking the bootloader has not been accomplished yet.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] paxtonanthony:
Does that mean that were just limited on what we can do with this particular system? 'Cause that just makes me feel, well, pretty let down. I haven't been able to install TWRP on this phone, yet I've had it rooted a couple of times. But, it seems that every time I even given the thing the stink-eye it loses its root. I just have to find a better root, and I'm getting a bit unstable in the sanity department trying to do it.
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] POWerSUrgeSW3:
If you keep losing root, are you doing any of the security and/or OTA updates? That will revert root for sure.

The situation with the device is no custom kernels can be used. Because the bootloader is locked. The best we can do, at this point, is go through a more basic root process and flash the engineering kernel, which unlocks the ability for Super User (root) access to be gained

I've had my S7 rooted for a few months now, and never had any issues losing root. And the phone is my daily device. What root process are you using?

I am getting ready to root my g9300 China s7 and only have two questions. There is no oem unlock option in my developer options and I'm on the marshmallow that it came with, so I'm a little worried about that. also, I've heard people not being able to use the front camera after rooting,which is very important to me. is this the case or not? will this root work without this problem? if it has a problem, I assume I can always unroot and go back to stock (which I'm also unsure how to do.) I have rooted several times, but never unrooted.

thank you for your help !

Another question for you guys. If I want to flash update to nougat via Odin, do I do that before or after doing this forums root process?! Still want to know if any of you had successful root without camera problems with rooting this g9300
[Samsung Galaxy S7 (Snapdragon) ROMs, Kernels, Reco] Yooperjusty:
Ok, I found updating to Android N is not a good idea. SO, anyway to root without the camera issue? Another question. My firmware says: G9300CHC2API3,

but I found the firmware: G9300CHC2APC7 that says "Open China." IS it possible to flash this and get gapps on our device without root? I really want to root because of the many benefits, but, without the front camera working, that would be no good, as I've read that no 3rd party camera apps are any good.

Install TWRP using Odin: https://www.skyneel.com/root-samsung-galaxy-s7-verizon-sm-g930v-twrp-recovery

Install TWRP using Fastboot: http://www.theandroidsoul.com/how-to-install-twrp-recovery-via-fastboot/

I was able to flash the recovery file with Odin3v3.12 PrinceComsy but, like I was alluded to earlier, the phone refuses to load the custom recovery.

Using the Fastboot method has it's own issues. I think there's some quirk in my process that prevents my driver from detecting the phone when it initiates fastboot. Right after I run the command I get the message: "< Waiting for any device>" and it sits there indefinitely.

I just want nandroid backups ffs. I'm just a cringy consumer that wants nandroid backups, too bad I'm not a "real developer"

You can install the recovery but it will refuse to boot it. Samsung devices generally don't have fastboot functionality.
