Can someone summarize what my options are with my AT&T G900A? It is running 4.4.2, NCE firmware and I would like to upgrade to the latest and greatest available while keeping root if possible.
What steps do I need to take from a high level?
I can't seem to find a 4.4.2 NCE to 6.x post with root.

No root on 6.x, SELinux will throw a fit and refuse to boot into Android. Highest you can get is 5.0.

I'm looking to probably upgrade from my GS3 to the GS5. I've read some of the posts on here about rooting, but I'm still a bit confused. It seems that root is only available for 4.4.2, but then you can't keep root and upgrade to 5.0.1. Is that correct?
Also, could anyone point me to a thread that lays out the root method for the phone? I see a lot of people talking ABOUT the thread existing, but no actual links to the thread.
Thanks in advance!

http://forum.xda-developers.com/att...w-to-update-to-g900aoca-5-0-keeproot-t3076803. This is to get root from 4.4.4.
Theres another method to root 4.4.2 u gotta downgrade to a different kernel then use towelroot and then flas the upgraded kernel. Theres a method on here by the same guy that did 5.0 one , just search his name you can find it

Note that OTA 5.0 just got pushed by AT&T and if you take it, there is currently no way to root or downgrade to 4.4.2 to use towelroot. In fact if you try to downgrade after the 5.0 OTA, you will end up bricking the phone. I'm sure devs around are working on finding a way to root the OTA, but as of today there isn't a way. There is an alternate method using FireFlash which is in beta to install 5.0 on a rooted 4.4.4. Note that if you are just about to buy a S5, it might be preloaded with 5.0 which until probably some time in the future is not rootable.
I would suggest delaying your upgrade from S3 to S5 until someone figures out how to root 5.0 OTA.

Gotcha. I'm not gonna not upgrade simply because root may not be possible yet if it's already 5.0, but that's good to know. Thanks.
Hey ho guys. I have a 5S with the Downgrade to NCE flash found on this board. I would like to have the latest Kitkat without updating to Lollipop and getting the locked bootloader. I just downgraded today to NCE and bravely did one OTA. It got me to NG3. Can I OTA again to get OA1 or will it jump me to OC4? Or should I use one of the methods here on the board to upgrade and totally avoid OTA? Thanks, later.

If you want root capabilities i wouldn't take any OTA. You'll still have to go back to NCE to root anyhow i believe. As far as the boot loader it is and always has been locked on the AT&T S5. The only method for root is towel root and I'm not sure if it'll work on NG3. If not you'll have to go down to NCE

Yeah, I should have preference that I am after root. But towelroot works on NG3, you can read about that here.

After I took the brave OTA I followed the threads instructions and it worked. There is a thread here that talks about root for OA1.
http://forum.xda-developers.com/att...to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120
It says just to take the OTA. I guess its still safe to take the OTA then after NG3? And I can't seem to find any rom on here thats stock OA1. Anyone know if I aren't seeing it? Thanks.

Most of the roms are based on nce or ng3. If you go to oa1 and flash a nce or ng3 rom your phone will be slow because of the different bootloader, and the camera is screwed up. I'd stay on ng3 and not worry about oa1. That's my opinion. I'm on 5.0 running the Twi5ted rom and having no problems with it. Most devs have moved to 5.0 lollipop and the 4.4.2 - 4.4.4 roms will be more and more abandond in my opinion.

Ah see I haven't tried any of the custom roms posted on here yet. But can I have NC3 as stock and on another ROM Slot (using Safestrap) have a Lollipop rom? Having one slot be 4.2.2 and the other be 5, basically. So the bootloader is different from NC3 to OA1, good to know. I'm glad I stopped at NC3 then. Thanks for your help.

I'm not sure on the different slots and bootloader mainly because when i used different slots the battery drain was unbearable. I don't know if they every fixed the battery drain issue when using different slots. It was bad enough that i just stuck to the stock slot and flashed only in that slot.
So here's the backstory, about a year ago I bought a fairly new Samsung S5 (SM-G900A) off of swappa.com. It's always been on Straight Talk, so I have never been able to receive AT&T updates. My problem with getting it to Android 5.0 is that my phone needs to be at 4.4.4. I can't find any firmware out there to upgrade from 4.4.2 to 4.4.4 since AT&T hasn't published their firmware. Any assistance/help/tutorials in finding a way to get my phone up to 4.4.4 would be much appreciated.

Are you rooted? Do you want root? 4.4.4 was not much difference from 4.4.2.

It's not rooted and I don't need root access. If root is an absolute must than I wouldn't have a problem rooting my device. I wanted 4.4.4 so I can upgrade to the stock AT&T 5.0 ROM.

Read and follow the instructions in post 1. READ THE NOTES SECTION at the bottom of post 1. You'll need to root with towel root first then you'll be able to flash up to 5.0. I don't know if any way for you to do it regular as i have never had straight talk.
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...
I have a Galaxy S5 (G900A), rooted on Lollipop 5.0 (0F3) using prerooted firmwares to upgrade from rooted kitkat. My bootloader version is still OA1. I want to downgrade now to kitkat so i can use safestrap. I was wondering if i could downgrade using the G900A_Downgrade_to_NCE.tar mentioned here and here, since i still have to OA1 bootloader, to downgrade without bricking my phone.

Yes you can use that downgrade file. I have used it many times. Your phone might run real laggy though after you downgrade. There is a thread somewhere that shows how to fix that issue. I'll see if i can find it for you.
