Root and upgrade out of country G900A

I'm not very hacky or what you call it, my know-how in this region is not very good, so I'm hoping someone here is able to help me.
When I was in USA I bought myself a AT&T Samsung Galaxy S5 (G900A), paid it off and had it service unlocked (called AT&T and they unlocked it for me). Then I went back to Ukraine and now I want to to be rooted... and have lollipop.
I don't know how to upgrade it to lollipop... Kies and the phone says I have the latest firmware and I cant get it updated. On top of that, I've read in posts here that if I update before rooting it, I might be in trouble later on the road.
Towelroot V3 says that my phone is not supported so I can't root it that route...
I've read tutorials here about rooting with the ND3 update... first of all, I don't know what the ND3 update is and how to obtain it since I can't update my phone OTA in Ukraine.
How do I go about this?

More information about my phone (since I learned more information about this process).
Kernel date is Tuesday July 22 2014... towelroot is said to work for any before June 3, 2014... this is probably why my phone isn't supported.
Also, is it true that Android 5.0 removes the SD Card functionality???

Well, I got it rooted... thanks to muniz_ri!
I just went ahead and risked it, not knowing what ND3 or NG3 was.
My next step is flashing it to Android 5+ ... that is if it doesn't remove the SD Card functionality

Well, I found these instructions on flashing my G900A to a pre-rooted stock lollipop... the problem I'm having is with FireFlash... I can't seem to find that app anywhere.

Thank you!!!!!

Wait, I'm confused - you say you were able to downgrade your G900A to a rooted 4.x state? I thought root was impossible once you take the 5.0 update?

You can only if you didn't take on the 5.0 OC4 bootloader and kept OA1

I didn't take the 5.0 update since I am out of the country and OTA updates don't come here... but I did have the NG3 update... so I downgraded to ND3, rooted and went back to NG3... then I flashed a prerooted 5.0 stock ROM with OA1 (I think...) and now I'm using it...

Need help with root on S5 (AT&T)

I am having trouble rooting my S5 (SM-G900A) . I tried using the Towelroot method with the different codes, it always said that the phone is currently not supported. Since I really don't know that much about rooting, it would reaally be helpful for me to have an easy-to-understand explanaition on how to get this thing rooted.

Root S5 At&T
Hi, I have the same problem, I have an S5 from ATT with lollipop 5.0, I tried to root it and now is showing me a notification that says that I have to take the phone to an ATT center to undo whatever was done, but no root, if you had any help with this topic please letme know, thank you

If you have lollipop installed, there is no root method and no way to downgrade. Boot loader is locked down like fort Knox as well. Not many devs use this 2 year old phone anymore.

super duper easy root

You can't flash back. If you have taken the 5.0 or later update, THERE IS NO POSSIBLE WAY TO ROOT OR DOWNGRADE CURRENTLY.

ah he didnt specify that he took an OTA update to 5.0. thanks for the clarification

I have Android 4.4.2 installed, but Towelroot still does not work. I bought the phone back in the USA, then unlocked it and took it to Germany two years ago. For this reason I can't get any newer Android versions.....

Same problem here. Got a code-unlocked AT&T S5 on T-mobile SIM running 4.4.2. Kernel is from July, so Towel root doesn't work.
AP: G900AUCU2ANG3
CP: G900AUCU2ANG3
CSC: G900AATT2ANG3
I want to do the following:
1- Root the phone without loosing the unlock
2- Update to Android 5
3- Replace the OS by unbranded android, ideally also get rid of the samsung bloatware as well.
Is it possible? I Spend 8 hours already looking for answers, but none f them apply to my specs.
Many thanks

Unlocked is unlocked. You can't lose that by flashing.

You can't do the OTA update anymore because its not available anymore. But you could download the OTA update file and sideload it.

Thank you very much for your reply. Good to know someone knows about this stuff. Just couple more questions if you could help.
1. Will the link mentioned by me in previous post work to root my phone with build G900AUCU2ANG3 and kernel date of July? http://forum.xda-developers.com/att-galaxy-s5/general/g900and3tong3keeprootota-zip-t2862299
2. How could I download the OTA update file to sideload it. Is there a link to download?
Thanks again for your help.

1. Yes, you don't need the OTA because you are already on NG3 so just start from step 2.

It works! Thanks so much. Now I have a rooted Samsung Galaxy S5 on running Android 4.4.2. Baseband G900AUCU2ANG3. Phone was originally from AT&T, unlocked and rooted, currently being used on T-Mobile.
1- How do I upgrade to a current Android version?
2- How can I remove all AT&T bloatware and have an unbranded phone?
Thanks.

Got a G890A with 5.0.2 that needs to be rooted .. update to 5.1.1 or not?

Hey guys,
I have to root a G890A for a friend to remove all the at&t crap and samsung/google bloatware but Im not sure whether or not I should upgrade to 5.1.1 first or not?
Which Version does run better overall?
The phone is sim-unlocked as far as I can tell, would rooting and/or flashing 5.1.1 affect that unlock?

Best version for me is is 6.0.1 because of the great battery life and the Marshmallow Android. However 5.0.2 had the same battery life unlike 5.1.1 where it was terrible.
The rooting/flashing will affect the unlock. As to the root for 5.0.2 - you can read how to do it here (the second page has the downloadable files):

but 6.0.1 is not rootable because of the locked bootloader, correct?

Yes, 5.1.1. and 6.0.1 are not rootable at the moment. Only 5.0.2. The link I gave you states that 5.1.1 can be rooted too but it's actually some kind of service mode which is no good and as soon as you flash back the stock 5.1.1 there's no more root.

So I rooted that thing now... throught that the recovery was actually a custom recovery but it just seems to be stock recovery with root permission.
Is there TWRP or CWM recovery out for the G890A somewhere? Would love to take a backup before I start the debloating.

Stock G900a downgrade from Marshmallow to Lollipop

Searching via cell isn't great for me at the moment. I've found a few threads with lollipop files to use in Odin. But I haven't read anything that says it's simple to flash them and downgrade properly from Marshmallow to Lollipop. Is there a tutorial/file thread already on here that I am missing via search? Is this something I can do without rooting?

Da hell is that chipmunk woman

Sammobile doesn't have the stock 5.1 firmware.. is that an omen against downgrading?

Most of the posts ive read are indicating Marshmallow is not able to be downgraded, bootloader locked.. looks like a dead end

It's a different boot loader, will not be able to downgrade. There is no root option at this time as well.

sorry, but i disagree. i just flashed from 6.0.1 to 5.1.1 using odin and firmware found here on XDA. I have no problems with phone so far.

At the time of my post months ago, this was not possible. It is very possible now, I have also done it.

This is for the AT&T model, I haven't been able to crack into mine. I have battery issues since marshmallow and want to go back to 5.1.1 as well... where did you get the files, and what process did you use?

following this guide for rolling back to LP, work for me downgrade from MM and getting root on LP.

Mine didn't... version DPH4, october 1, 2016 security patch, odin gave me an error something like level 4 > 3 and didn't start the reflash process. I was able to reflash the same 6.0.1 and its not the same as what was on there, so maybe the ota updates had a problem? I'm still locked out of downgrading.

Mine also from DPH4 oct 1, 2016. Having issue with lte, i cant receive call but i can make call. So im rollback to COI5 and follow the instruction from page 2. Get odin 3.11.1 to flash BL,AP,etc. Have you try with other usb cable?

i also have the at&t model, but used some info in this post: https://forum.xda-developers.com/att-galaxy-s5/general/guide-merry-christmas-heres-t3516196
i used odin to flash full OI5 firmware, minus the bootloader file. Only use the AP, CP, and CSC files. the bootloader is the same. and really, i had already flashed the PA2 build earlier that day i remember now. would probably do that first. flashing the PA2, i used all four files, BL, AP, CP, and CSC . they both flashed the first time, if they dont then try a different cable first. usually that is my issue.
so , i flashed from 6.0.1 down to 5.1.1 pa2, then down to oi5. still have no problems other than getting root..... im focusing on bootloader now, i have unlocked them on htc's before, but havent tried any other phone yet. the work continues tonight.

Can I Take any verizon updates go back to previous versions for future possbl Unlock.

Does anyone know if I can take the current Verizon software update From Sept 1st NRD90M.G950USQU1AQGL. I Will I be able to revert back to the original stock OS version with Odin if I update it? Does SamPWND work on this or any updated OS software. I would like to get an update to allow me to use Bixby voice, the stock Rom is missing that, is there any safe update to take.
Reason I ask is that normally you need to stay on the original stock OS or downgrade if there is ever a bootloader unlock method ever found. I tried looking for this kind of info couldn't find it. Usually there is a thread with stock roms with this info but I can't find any. Any suggestions?

I took the first 2 Ota updates and flashed back to original firmware without problems before I switched to unlocked firmware. Sorry for the late response.

You should have no issue doing so as long as they don't mess with the bootloader
