g930v root 8crj3 version?? - Samsung Galaxy S7 Questions and Answers

Hi guys
I updated my s7 by OTA to last update version G930VVRU8CRJ3
i have tried all possible method to root my phone and it's all faild
does anyone have a way to root or downgrade it??

If it's a G930V you can't downgrade, Snapdragon bootloader prevents downgrading.
There are some root methods in the Verizon / T-mobile S7 subforums.
Note that the USA models have a locked bootloader that can't be unlocked, so root involves using a leaked engineering bootloader to bypass the restriction, which can have mixed results.

I think this is the problem I notice it from one of T-Moble s7 theards is any solution for this case
((I did NOT base it on G930TUVS8CRJ1 (the latest) because that has bootloader ver8, which we don't have root for yet. (DONT take that OTA since you can NOT downgrade!) And if I had to guess, the only difference are some minor security updates, but mostly the security update that prevents root!!! ))

Any offical root for Galaxy s7 Sm-g930u?

I've had the Sm-g930u for a while now and irritated that there are no officials roots for it yet. Unlike its other variants. Im wondering if there ever will be a root for sm-g930u.
Oh the Snapdragon Variant, I think there's no way ( yet ) to root Snapdragon Variants as the bootloader cannot be unlocked and there is also no way the bootloader could be unlocked. I don't know what the US Carriers plan to do about this issue but for now the bootloader is not unlockable.

New Update - PL1

It says it provides the latest Android Security Patch on the Verizon Galaxy S5 Update page.
Now that the Odin FW is out, I flashed an Odin tar of the FW without the aboot and still have a Dev Edition phone. Now we just need an updated aboot.

It says it provides the latest Android Security Patch but if you notice, there is a difference in the "middle" of the build number, which happens when they update the bootloader.
Verizon Galaxy S5 Update page
The first time they updated the bootloader, it prevented downgrading. The number went from G900VVRU1 to G900VVRU2. This time, it's going from G900VVRU2 to G900VVRS2. What does this mean? I have no clue. But I do know that nobody should update until someone like @muniz_ri or @jrkruse has a look at the bootloader to see what exactly this changes. Hopefully it doesn't remove the ability to have Dev Bootloaders anymore.

The 2 in the version represents the bootloader version usually as long as that doesn't change you should still be able to downgrade

But what does it mean when they change it from VRU2 to VRS2?
The VZW S5 bootloader has always been VRU1 or VRU2. Now all of the sudden they change it to VRS2? They had to have changed something.

No matter what they change, I think it will be unlocked forever.
I have seen the update yesterday but still not tested as s5 is my daily driver.

No if they make it so we can't downgrade then their will be no way to obtain root. Since my bootloader update isn't always successful you could get stuck without being able to root on a worse case scenario. Now you can always start over and reroot

You are right, if no root there no unlock.
But If you noticed that all the unlocked devices, Note 3, Note 4 and S5 are downgradeable. S3 and S4 are not!
I think its all about eMMC not the bootloader.

If i read your post correctly, I believe that you may be incorrect on the last sentence. To unlock the bootloader, the devices mentioned need to have the Samsung eMMC 15 chip to aquire unlocking the bootloader.
Also, pretty much the same as the S5, N4 & N3, the S3 & S4 are downgradeable IF you didn't take the update that locked the bootloaders. As i know because I still own my VZW S3 which is unlocked and running TWRP recovery

I own S3 locked on 4.4.2 and 15 CID and no downgrade caused by eMMC and the aboot together, I think there a fuse triggerd so we cant unlock and downgrade.
My S4 is 11 CID and no downgrade too.
The PL1 update is not up yet so we cant be sure it will lock the bootloader or not, but the S6 already has same bootloader versioning letters on the new update!
I also noticed that my Tab 4 (no carrier, wifi only) just got an update for the first time in like a year and it's bootloader version changed from UEU1 to UES1. Maybe it doesn't mean anything after all.
Well now that the odin firmware came out this morning, I created a .tar without the aboot, flashed it, and I still have a Dev edition with the PJ2 aboot. Hopefully @jrkruse will create a bootloader update zip for the PL1 aboot.
The VZW S4 just got it too.

I'm not the sharpest tool. If the S4 Bootloader was locked via EFuse, how did they update it?
Anyone got and update zip for pl1 ?

I was able to obtain root access on my device running LRX22C.I545VRSGPL1, bootloader was indeed updated, could it hinder progress on finding an unlock?

G930A - ATT - Downgrading From Nougat to Marshmallow

Hello,
This might be a repeat question, but somehow I am not able to get a stable solution.
So I am on G930A ATT and just received Nougat update. However, I would want to go back to Marshmallow 6.0.1
My device is NOT rooted and is locked to ATT.
Any suggestions how can I get back MM 6.0.1 ? Can someone please guide me with detailed steps and tools which can be used.
Thanks.

G930AUCU4APJ4

Don't think you can as your S7's bootloader is locked meaning downgrading won't work, only upgrading

Thank you for response.. But could you please elaborate a bit.. so I can't downgrade due to the fact that my device is locked to ATT..
If it would have been unlocked, then I could ? Trust me, Nougat update is really annoying and I really want to get rid of it..

It's the bootloader of the US model S7s (Snapdragon) that prevent it, along with preventing flashing custom recovery afaik
Usually you would just use ODIN and grab the ROM you want to flash from updato.com or sammobile but I'm almost certain downgrading is blocked if the bootloader is locked
Not specifically anything to do with your AT&T carrier, it's the phones themselves that are locked
Some info here about snapdragon S7s and their locked bootloader

Since the US models have a locked bootloader, it's much harder to root than international. I think they'll reject anything from Odin that isn't official firmware.
You might have more luck in the US/Snapdragon specific sections of the forums, near the bottom: https://forum.xda-developers.com/galaxy-s7

I thought oem unlock was unlocking the bootloader? I can simply do that in developer options.
OEM unlock as in the developer settings menu? That toggle only works on Exynos (930F/FD/W8) devices, on Snapdragon (930U/V/T/P/A) it doesn't actually do anything. SD bootloader has and likely will always be hard locked.

So why all the tutorials and YouTube videos on all the different methods of rooting snapdragon s7 if the bootloader doesn't unlock for root. Wtf
I've never watched them so I can't say, but I would assume they would use round about methods to do it? For example Exynos is simply flash TWRP on with Odin, then flash a SU zip.
Do the youtube videos tell you to do that with the snapdragon models, or is it some arbitrary multi step process? The only way I can imagine rooting Snapdragon is exploiting security flaws. I've also seen mentions of flashfire but I don't know what it does.
Like I said you'd have better luck going to the AT&T/T-mobile/Verizon etc sections. This area of the forum is mostly for Exynos.
I don't even know what this phone classifies under.
It was a Verizon phone, with Verizon logo on back.
Unlocked.
Now it's on TMobile Network.

Isn't there a method to unlock a bootloader?
Carrier unlocked just means you can use it on any carrier network, which is you've got.
But bootloader lock is at a firmware level, and can't be done for any US model S7.
Since all the US models are basically the same, any guide in any of their sections should work for any other model. Yours is a G930V but you can use any guide or firmware from any other US model S7.
You need to root using an engineering bootloader. Not sure if there's a version compatible with the latest update.
You will have problems, as eng BL is not stable, and your battery will not charge past 80%.
So basically is really difficult/impossible Root a 930u? and more difficult flash with a custom firm?
Investigating because just buy a Samsung S7 gm-930u and want to debloat it.
How can i know if is a snapdragon? I am on new zealand not US.
Rooting is difficult, flashing custom firmware, as in a ROM is basically impossible on snapdragon SoC's. With a locked bootloader you can't modify the boot image which is needed for ROMs.
To check your model boot into download mode by turning it off, then pressing and holding vol down + home + power. In there it will tell you your model, being in new zealand you should be on a SM-G930F or FD unless you grey imported.
Same button combo for ~10 secs gets you out of download mode.
Yes is the grey and is 930U pitifully.
So I should sell it and buy another one haha
Thanks for the advice.

Need help rootijg the GALAXY S7 SM-G930T T-Mobile Variant

Im new to thus ohone and how do i root this phone it's on Android 8.0.0 and idk how too root i tried cf-auto root but bootloader fails idk how to unlock bootloader
The snapdragon / US models (G930V/T/U/S/P) can't unlock their bootloader
The only method is using a leaked engineering bootloader that's unstable and limits charging to 80% then using flashfire, but I don't know where to get this BL from.
