Downgrading Samsung Galaxy s5 ( 5.1.1 ) ( SM-G900A )? - AT&T Samsung Galaxy S 5

So I did some research if there was any way to root Samsung Galaxy s5 (5.1.1) (SM-G900A). People were saying you can't downgrade because of a locked bootloader or something. But I found one firmware that was meant for tests that brings you back to 4.4+(Can't remember exactly, but it was 4.4). Is there a way to go to this tested firmware and go back to a firmware that could be rooted?

Thanks for reply
But I didnot find lollypop 5.0 update for this specific Base Band Version :N900AUCUCNC2
My device is not rooted I just want to install original at & t lollupop update..
Thanks
You don't need to find the nc2 baseband... you said you are already on NC2. NC2 is kitkat.
If you want to install stock lollipop 5.0 on the att note 3 n900a phone... then you need to install the lollipop rom that ends in OC1.
You cannot stay on NC2 and have lollipop, because the current stock lollipop is OC1.
You don't need to be rooted to install it. You need to use ODIN to install it and you will still be stock and not rooted.

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?
