How to Root AT&T Samsung Galaxy S5?

I am not new to rooting but, it has been a little while since I have actually decided to do so.
Currently, I am trying to catch up and see if it is possible for me to root at this time. I have an AT&T Samsung Galaxy S5 which I just got from insurance because I completely shattered my old S5. The phone came with the new baseband on the phone but here are all my specs:
Model: 900A
Android: 5.0
Baseband: OF3
Kernal: 3.4
Please, let me now if there is a way to root, downgrade to root, etc. I would like to have a rooted phone asap:good:
If you can confirm your bootloader is not of3 then it may be rootable. If it is not oa1 or below, no root for you.

Data Recovery after hard reset - *unrootable* Verizon S6 Edge

I have a Verizon Galaxy S6 edge that mistakenly underwent a hard factory reset. I want to achieve root to recover the files on the phone: pics that had not been backed up, wassapp, etc. Now I find that the phone cannot be rooted at the present time because PingPong Root does not root the updated baseband on my phone. Even if I upgraded to 5.1.1, I understand there is currently no root for the Verizon G925V 5.1.1.
I am looking for information on what could work to recover the data from an unrooted Verizon GS6 Edge? :crying:
Model: Sm-G925V
Android 5.0.2
Baseband G925VVru2aof1
Kernel Version 3.10.61

[Help] Updating to Marshmallow from 5.1.1 (g900aucu4coi5) stock rom & no root

I just purchased a Galaxy S5 unlocked, but its an at&t model (g900a, shows at&t logo on boot, has at&t bloatware). I live in New Zealand so I can not use an at&t sim and update to the latest firmware (ph4?). Im stuck on g900aucu4coi5 and I want to update, and I have found a guide: http://forum.xda-developers.com/att-galaxy-s5/general/galaxy-s5-android-version-6-0-1-t3419016
Can I just flash ph4 with odin 3.11.1 and I will be fine? No chance of brick or tripping knox (assuming i follow instructions correctly)? Also is there a way I can debrand my s5 and give it a stock s5 rom w/out the at&t crap without tripping knox?
This may seem like a noob question but I have followed instructions to the letter while flashing roms on a galaxy trend plus and a galaxy y duos, and encountered problems down the road which led to bootloops. I assume this was because the tools made for them were still in beta for these devices were not popular, but I still want to be safe and keep my new s5 alive.
Thx

You should be able to go up to PH4 using ODIN no problem.
And about the bloatware... As soon as we find a way to root or preroot Marshmallow we'll probably get some debloated ROMs up, but first we have to find a way to preroot (I'm working on it but it's taking the back burner for a bit while I work on other ROMs so anyone is welcome to give it a try)

Yes, and no. It updated, started overheating and the battery caught fire. Rip.
I'm in the same boat as I have an ATT S5 with Lollipop and tried the above method w/Odin and it is now a brick, stuck on the ATT logo.
Are there any working accessible sources fore the ATT stock Firmware for Lollipop in order to rollback this MM update? I've been looking and have found none.

Is G925VVRS4DQD1 (Nougat) Root-able yet?

I got a Samsung S6 Edge (Verizon SM-G925V) today and heard I should upgrade to 7.0 (Nougat) firmware and hope it gets rooted soon. Is the baseband version I have root-able? It's G925VVRS4DQD1
To my understanding, the tool on autoroot.chainfire.eu WOULD work, but because the bootloader is locked down, it will brick the device instead? Is that true? Is there any hope that 7.0 will be rooted soon for my device? Any input on this would be helpful, thanks.

I tried it it said something about recovery not sure what but in Odin on the phone screen it said recovery fail
So do i. However, it won't brick your phone. One time i tried to upgrade to 7.0 or downgrade to 6.0, first boot i saw a pic of a lock is unlocked when i first boot. Next time i boot, it disapppears. Any idea?
I think this phone is unrootable for now since Verizon is like "you can't make it because i don't wanna my phone naked, haha"
Same problem here. recovery fail. How can I root my G925V Nougat?

Downgrade Options? SM-T710 Nougat

I have a tab s2 sm-t710 on nougat T710XXU2DQCL that was installed OTA and would like to know if i am able to downgrade to 6.0.1. The device is 100% stock and was wondering if ODIN would give me any grief about downgrading. The PDA number of the 6.0.1 file is T710XXU2CPK1 (Cellular South).
Thanks
On paper, I think you should be fine. :angel:
I'd also like to know this as battery life seemed much better on 6.0.1 for me.
i did downgrade my T 815 from 7.0m to 6.01 using odin. didnt face any difficulties. i did a complete wipe/format after i downgraded .
Can you not downgrade with TWRP as well?

I used Odin and firmware downloaded from sammobile and it worked flawlessly. I've performed downgrades on over 100 tablets so far and they have all worked good.
Downgrded my t713 long time ago and didn't have a single problem, you just need to download a compaitable firmware from sammobile!

You're safe to downgrade as long as it's allowed. Older builds will fail immediately so there is no harm to downgrade.
I've seen a few people asking about downgrading. Whats the reason behind this? Is N glitchy?

N does not work at all well with DJI drone remote controllers. I foolishly updated my brand new SM-T719Y 8" and Now I cannot connect to my drone at all. I have an pre 2016 Tab S2 on Android 6.01 and bingo works.
This size pad is the preferred size for drones and has enough grunt to provide stutter free vision. Cannot comment on anything else about N as this pad will only be used for my drone...

Hi Beut,
I have been trying yo downgrade my Tab S2 SM-T719Y LTE from Nougat to 6.01 and have correct downgrade and Odin. Every time I try to downgrade it fails straight away, so I was wondering what you ment by "as long as it is allowed" & "older builds" will fail immediately.
I need to get this happening as I cant fly my drone.
Cheers Yts...
I don't have your model so it cannot verify. However, other models I can downgrade to older builds close to the Nougat.
Like SM-T580 or SM-P580, both are Android 7, QF1 and QE4 respectively. I can downgrade them to PL4 or PL2, Android 6 but not the PG1.
Q: 17 or 2017
P: 16 or 2016.
The second letter is the month it's released.
You also need the right bootloader, different OS has different bootloader. Many just flash the AP file only without bootloader, it'll failed when downgrade.
Is it possible that you cannot downgrade Nougat to 6.01 as every time I try on my SM-T719Y Tab S2 LTE, it fails straight away. I have tried 3 different downloads and all failed, but Odin will let me overwrite my Nougat with a downloaded version of Nougat from the same web location as I got one of the 6.01 firmwares from.
Here are my fail messages.

Is it me or is it this model of the Tab S2 SM-T719Y????
When downgrade to MM you need the BL ( Bootloader ) goes with the AP . Boot loader of Nougat is not the same as MM , however bootloader of LTE version is locked
Sammy doesn't want you to downgrade.. nougat is planned obsolescence, I'd say.

Hey I've been trying to downgrade my T719Y for days now. Constantly failing and googling everything I can to find where I'm going wrong.
How would I know if I have the LTE version? And if I do and the bootloader is locked, does that mean I can't downgrade?
If I don't have the LTE version, you're saying I need the bootloader and AP to downgrade? Where can I find the bootloader?
I'll keep searching and trying but this is wearing me down. Any assistance would be greatly appreciated. My surveyors can't do a damn thing with our giant UAV until I fix this
LTE version is the one that has SIM, usually it's next to SD slot. Most LTE versions have locked bootloader, that's why you cannot downgrade firmware.
I just kept an older phone for apps available only for 6.0. Like scr recorder. Otherwise there are no reasons to downgrade
