Hey guys!
I'm trying to root my "Samsung Galaxy S5 Active" - "G870A-0F2" - "5.0"
I know that there is no current root for 0F2, So I am trying to Downgrade my phone, I downloaded the stock firmware "NE4", Put it in AP for Odin, & I keep getting a FAIL. Any help would be awesome! How can I Downgrade my 0F2 Firmware.

Hello,
After doing some research I've found this thread mentioning a user with the same phone model (G870A) that successfully downgraded from 5.0 to 4.4.2.
http://forum.xda-developers.com/showpost.php?p=64386453&postcount=8
However, I think he was using a different bootloader version, which may be older than yours, and may also explain why he succeeded and you didn't.
The user posted a tutorial link and step-by-step instructions in the thread I linked above. I thought maybe it could help you.
**EDIT: original firmware for G870A can be found in this thread (filename is "G870AUCU1ANE4_Full_Odin.tar")
http://forum.xda-developers.com/att...to-root-g870aucu1aoa1-4-4-4-2-7-2015-t3025119
**EDIT 2: You may be in luck! This very kind user has posted more info about downgrading from 5.0 to KitKat (4.4.x):

SuperSU stopped working
I was able to use JOdin (mac user) to upload: CF-Auto-Root-m3-m3zh-gti9305.zip [download.chainfire.eu/232/CF-Root/CF-Auto-Root/CF-Auto-Root-m3-m3zh-gti9305.zip]
Now, everytime I boot, it keeps saying SuperSU stopped working. I can't use Superuser to update. I was going to load TWRP and try to update SuperSU, but now JOdin continuously complains the PIT file is corrupted.
Thoughts?

Yes, you can root straightforward. The root does not make changes to your system i think.

Yeah thanks I figured out I am on NG3 and I tryed last nite, did follow a tutorial, and then i used root checker, and it said my device was not rooted. SO Im not sure what is going on.
I Install the ND3 File, Then do root. I then use root checker and it says Im rooted. I then Install the NG3 file and then check if Im rooted,. and it says Im rooted.
Then Download SuperSU from Playstore and Upgrade to Pro and then use rootchecker and it states Im not Rooted. Is the phone still rooted? Or am I doing something wrong?
EDIT: Got it working now. Thanks again

I'm a complete neophyte at this entire process so please excuse my ignorance. I want to root my AT&T Galaxy S5. I tried the Towelroot, but I got the phone is not supported message as well. My question is what on earth is NG3 and how do I proceed from here? I have Odin 3.1, I just don't know what to do with it. Help...

First of all you'll need to read here

NG3 the official AT&T build that patched towelroot that's why that apk doesn't work any longer. Your device can be rooted using @muniz_ri thread I posted.
I personally use Odin 3.09
Please read a lot more and take your time in the two threads I posted so you don't make your device a very expensive paperweight.

Downgrade AT&T Samsung Galaxy S5 G900A from 5.0 to 4.4.2/4.4.4

Few days ago I bought the Samsung Galaxy S5 G900A unlocked. There was Android 5.0 preinstalled whith baseband vOC4! I tried to make the downgrade to 4.4.2 because of the root, and always gettin the brick. Saw the post about flasjing G900A_OC4_Stock_Partitions and it helped me a lot with unbricking! I tried all the ways of downgrades: recovery ZIP update (including OC4 firmware w/ OA1 bootloader) , ODIN flashing different stock roms, custom roms, kernels etc. Can I make a downgrade with that baseband? I've read somewhere that it's impossible to do in this case...
Really confused now after all this.
No need for confusion. There is no way known to humanity that will allow you to downgrade from 5.0 to anything else.

Ah, that's a shame..... Any chances of developing the 5.0 root for g900a?
Im in the same situation let me know if anything changes im about to return mine and hopefully get one still on kitkat or get a tmobile version

ODIN back to OC4 to unbrick and remember; if you can't root you, can't do anything but wait for root or buy a different model phone.
ODIN back to OC4?
There is no way at this time to ODIN back to OC4, OA1, or whatever.
There is only a ".exe" file for OC4.

similar situation
Hello guys,
my situation is quite similar to the posters one. i've bought the S5 active (AT&T) with some custom TMS5 rom, when i boot i sie unlocked lock icon.
the version is 5.0: the kies is showing info like: G900FXXU1BOC7/G900AATT3BOC4/G870AUCU1BOC5/G900FXXU1BOC7 (ATT)
the question is can i get somehow to the STOCK firmware? maybe upgrading to the 5.1.1 will get rid of this "custom stuff"?
if so, what's the best way to do it?
I purchased a new G870A Galaxy S5 Active this week, which was preloaded with OC5 (5.0, Lollipop) firmware. I was able to root the device by downgrading to 4.4.2; the guide here was very helpful: http://www.droidviews.com/update-att-galaxy-s5-active-to-lollipop-root-it-and-enable-wifi-tethering/
The exact procedure I used:
1. Flash NE4 firmware with Odin (The latest heimdall from git didn't work; I had to boot Windows 7 and install Odin & Samsung USB drivers)
2. Reboot the phone in recovery (power+volume up+home). Use the options to clear cache & reset to factory default
3. Reboot the phone normally. It might appear bricked & take up to 5 minutes to get past the AT&T logo.
4. Root with Towelroot
5. Follow the instructions on the linked page to install pre-rooted OF3 (Lollipop) firmware and the OC5 bootloader.
6 (important). Kill OTA updates by renaming /etc/security/otacerts.zip & /system/priv-app/wssyncmldm and then rebooting. Delete anything in /data/fota for good measure. (Use your favorite root-enabled file explorer or shell.)
Note that this will not work if the phone has received OTA updates beyond OC5. See this thread: http://forum.xda-developers.com/att...w-to-update-to-g870aoc5-5-0-keeproot-t3083841

Rooting for samsung galaxy s5 active (sm-g870a) android version 5.1.1

Hi all
I have been trying to root my phone but I think I bought the most annoying phone to root. I hit a wall on every direction so far, from what I can understand, rooting for the new version of android is hard enough but the active is somehow more difficult than the regular galaxy s5. I have been told to downgrade using odin but I will need to get the matching older version of baseband and kernel. I'm not sure if this is what I need or even where to find them. Have anyone rooted a galaxy s5 active recently? any suggestion would help.
Thank you so much.
nvm sorry for the post..... this phone has no hope..

Remove Root and Update On SM-N900A Please Help Very Confused

Hi All,
I am a newbie to the root world and in a lapse of judgement I decided to root my phone a year or so back. Naturally I had no idea what I was doing but I think I sort of did it. Now my phone is in this weird root limbo where it is rooted but not really. I can't unroot with supersu it just gives me an error or keeps spinning and does nothing. On boot my phone says Custom which tells me it is kind of rooted and some apps wont work as it says my phone has been modified or has root access. Also my updates fail but I have never quite gotten full root access and things just act weird. I guess that's what I get.... So naturally I have come full circle and would like to remove root and just install a stock rom so I can receive updates on this thing. Also, I am terrified of bricking it. I have searched all over your forum and found 18 versions of 15 roms with 13 ways to do it and I have no clue which way is the correct way. I know baseband plays a role along with version. So here is what I have;
Model: (AT&T)
SAMSUNG-SM-N900A
Android Version:
4.4.2
Baseband Version:
N900AUCUCNC2
Kernel Version:
3.4.0-722276
I hope I didn't miss anything. Some clarity on this matter would be most appreciated and I want to thank anyone for helping me. I hope this post isn't a repeat of some previous post. I tried looking but some details were slightly different. Please help and thank you in advance.

Aside from the fact that NC2 (that's really all the information you need - NC2 for the N900A - isn't currently listed at SamMobile, that's really all you need. Once you download the firmware, you just use Odin to flash it to the phone. I'm about to leave the house or I'd upload it to Mega and give you a link to use to download it (if you trust me - it's exactly the firmware I downloaded from SamMobile when they had it up a few years ago.) Post here if you want me to and I will. Or just look around this forum (AT&T Samsung Galaxy Note 3) for an NC2 link. (You'll be updated over the air, to 5.0.1, if you're not rooted, though, so you could use an unrooted OC1 or OC2 firmware, which are here (somewhere). (Oc1 and OC2 are the Lollipop ROMs.)
Edit:
Walter has a link to the OC1 (Lollypop) ROM at https://forum.xda-developers.com/note-3-att/general/100-stock-lollipop-5-0-n900aucueoc1-t3069609 You probably want to back everything up, then use the 4-file version. Then you can restore everything except root.
