I apologize in advance for my ignorance.. But after searching the forums and Google countless times, I am left confused as to whether or not it's possible. Many this I've read imply it's possible, yet I cannot find clear and definitive information.
Currently my S5 Active (g870a) is on Marshmallows PH2. Can I downgrade from this build on this device to a build which is able to be rooted?
Like I said, I've seen guides for downgrading but they often start referring to the regular S5, so that's where I'm getting lost.
Thanks
Yeah you can downgrade to OF3 by this guide. If you lucky you can find root with that.

This is my first Android phone i have owned for a few years now and i made the mistake of doing the OTA update to 4.3. I would love to root this phone because that was a big reason why i got it. I hated waiting for a jailbreak for my iPhone and i want a phone that i have control over. is it possible to "downgrade" from the OTA update to the leaked update? or even downgrade back to 4.2.2? I have looked around but cant find anything to helpful for the galaxy s4 active. also reading around multiple people say they end up having issues after downgrading or the KNOX counter going from 0x0 to 0x1, therefore voiding warranty.

While the OTA upgraded Android to 4.3 it also included a new bootloader. The new bootloader prohibits "downgrading" to a firmware version below ML2. Currently there is no way to downgrade with the locked bootloader. However there is a new thread just started by @TransformixS4 that is looking at injecting root into the ML2 Odin files, so it may be possible in the future to root ML2. There are a couple threads in the regular S4 forums exploring ways to exploit the bootloader and flash custom kernels.
Back to your situation: you're completely stuck. Next time you see there is an update or OTA check XDA before you install it. There are a couple threads that explain the pros and cons of any updates. There is also a thread summarizing all the AT&T i537 firmwares which will be updated in the future and you may find useful.

My issue was I kept telling it not to upgrade, and then it went ahead and did it anyway! On 4G, not wifi even. I was so mad when I got home and started reading that all the stuff I downloaded to root it *that day* would no longer work.

You're only allowed to delay the update 4 or 5 times before it installed automatically. You can prevent it from upgrading in the future by freezing some system apps with Titanium Backup. I don't remember which ones right now, but if you search it's pretty easy to find.

Just checking, you do have the i537 not i9295, right?
Hi xda
I have referred to this site many times for help but never became a member until now - I seriously need some help!
I recently bought a second hand S3 LTE which I knew was locked but as I had unlocked a few phones in the past I thought it wouldn't be a problem... until I encountered Android 4.3 and its bodyguard Knox. Searching on forums I found many other people experiencing similar problems but nothing conclusive that didn't involve using a Z3X box which costs about as much as I paid for the phone.
Apologies if this has already been covered in some form in another thread but I have done a lot of searching and a lot of hair pulling before coming to this stage.
So to cut a long story short I managed to successfully root the phone using CF through Odin and installed the version of SuperSU capable of bypassing it (downloaded .apk as opposed to play store which some people had said worked).
Next stage was to remove Knox, I installed NoBloat Free as suggested by someone in another forum and I basically removed anything with the word Knox in it and that seems to have done the job.
Now I just need to unlock the damn thing! While I have had some experience with rooting / unlocking a few android phones etc I really don't have much knowledge on the subject and pretty much forget it all in between phones :silly:
For the record I don't care about warranty, flags etc and am more than happy to downgrade if it means getting the phone working.
Any help would be greatly appreciated!
[A] Need help unlocking S3 on 4.3
Hi. The only way I know is via 4.1.1 ROM as explained here: http://forum.xda-developers.com/galaxy-s3/help-i9305/sim-card-unlock-samsung-galaxy-s3-gt-t2185866 (no root needed, just install the 4.1.1 using Odin)
I recently unlocked a stock 4.3 I9305 downgrading it to 4.1.1 first. It worked fine and then I restored a Cyanogenmod 4.4.4 ROM I had from another I9305 of mine. And then on CM I "lost" the IMEI (it happens), but I easily recovered it.

I looked though the forums and saw a LOT of questions with a LOT of answers saying No out of luck. But, I just bought an AT&T unlocked phone using it in Barbados where I am with my carrier. It's on stock 4.4.2 yet towelroot says it's not supported.
I read about having to flash something with odin. and bringing it down a bit in order to obtain root. Can anyone link me to the thread that has the information relevant to this question?
Sorry if it's been asked a lot, but I just saw a LOT of 5.0 threads not 4.4.2 that are not supported.
Also not new to rooting I had a HTC Vivid and a Kindle Fire HDX rooted. So I have a bit of knowledge on the topic.

Go to the OP and download the "downgrade to nce.tar" flash with odin in the ap slot then root with towel root. Use either safestrap or Flashfire for custom recovery. You can not use twrp or cwm cause of the locked bootloader.
Edit: the link is for the galaxy s5 not the s5 active.
Excellent. Great find. Thanked. Fast reply also.
Me again. So I'm here trying to find a way to get to 5.0 and keep root. Read a thread somewhere on here about using flashfire. I understand it I think only thing is when I go to play store to get the flashfire root version...
It's not available in my country and I can't find the apk otherwise anywhere.
What options do I have?

Did you read and follow step 1 and 2 in the OP of the thread that i posted to you. If you follow those directions you will get Flashfire.
try here http://uploaded.net/file/zqe4yys4
Had a parsing package error with your file. I found the previous version and used it. Worked flawlessly.
I love the instructions on XDA. Devs are great.
Thanks again.
I guess this will be a good start for others like me.
I need some help rooting my phone. I dont think I can use PingPong root because I have a base version of G920AUCU2AOF3, and I don't think it's supported yet. I only know of one other way to root and its Here. I cant figure out if I can root and not trip KNOX or anything else. Can I root with this without any repercussions or is there another way to root that is safe?
You need to search the forum, this has been asked many times before.

The answers to all your questions have already been answered. Effective search techniques, which you apparently lack, would find them. But I will spoonfeed you the answer and further clutter the forum, making it more difficult for others to search.
If you are on unrooted OF3 or OF4 on an AT&T device, you cannot root now, and you cannot revert to an older build. You will have to wait for a new root exploit to be found. Or return your device and buy an international one with unlocked bootloader.
I read threads that say you can't but they were older. If a question is asked multiple time, to fix your problem, maybe a stickied thread is needed.... Just a thought.
I'm kinda a noob at this but I'm not completely clueless. .. I've tried a couple one click apps, watched a few videos, and read countless articles without any luck. .. can someone help me? If it's even possible....
From all I've read, no, you can't. You can root NC2 (Android 4.4.2 KitKat) or OC1. You might check this post out.
An old thread, but I just wanted to leave this for others.
There aren't any public tools to directly root the OC3, OC2, or OC1 Lollipop firmwares for the N900A.
However, it is possible to achieve root by wiping the phone, installing the NC2 (KitKat) firmware, and then upgrading the OCx, while preserving root access.
I had followed the threads (at the time back then) using SafeStrap methods, but I couldn't get SafeStrap to work with OC3, so I had to abandon SafeStrap and use FlashFire to install OC3 and maintain root.
After that, I deodexed OC3, install xposed, and was up and running happy.
I'm not sure exactly what Samsung fixed, but OC3 was released a full 18 months after OC2, so I think it's a more secure software release (only 2.5 years old, instead of 4+ years, heh). I recall that on OC2, some of the stagefright CVE's still showed as vulnerable, but I just ran the Zimperium app on OC3 and see it reports that it's not vulnerable to any of the CVEs.
@digitalcandy4me thanks for the helpful info. This is one of the few times I've read this solution. It's the only one I've seen that seems promising.
Like OP I'm newb. But I've never rooted a phone. I've done plenty of other tech but I hate coding. I just want to change the dumb stock rom on this phone. Bloatware haunts me simply on principal.
I have "unlocked" att 5.0 lollipop Samsung n900a 0c3 and info on this phone is crickets. I have no idea how to downgrade to 4.4, I'm not confident it will even work but I'll try it. I paid 70$ so no big deal + it seems like I couldn't even succeed in bricking this stupid vault.
ANYWAY could you possibly give some more detail on how to do this? I know people hate getting vague questions on this board but it seems like there's no where to find answers. I really have looked.
