I recently bought a galaxy S6 and realised that it was rooted. I want to unroot it so that i can update to marshmallow. Currently im running on 5.1.1 and baseband version is G920AUCU3BOI2. Im trying to look for an AT&T stock firmware but i cant find one. i managed to find this through one of here threads :theandroidsoul.com/download-galaxy-s6-stock-firmware
Can i used this to unroot my phone and directly go to marshmallow? and also since im not in the US will my phone be locked? i mean will i still be able to have network service where i am.
Desperate to unroot my phone
Last year, when I unrooted, I ended up flashing the firmware again to wipe out root and go back to official status.
Look in the S6 general forum for a build of BOI2 and flash it, then use the software updater in settings (or try smart switch) to update.
Another option is to goto best buy and have the Samsung people restore the software and update it. (haven't done this, not sure how root will impact their flashing)

Ok so many of us have successfully rooted our devices and frozen update and renamed security files to avoid losing our root.
What are the proper steps for Dummies like me to accept the Lollipop OTA in December without losing my data?
Also now 4.4.4 is anounced with Bluetooth fixes that I have noticed while streaming
(My gut tells me keep update frozen until a flashable rooted 5.0.)
It was said in another thread NOT to take the 5.0 update until a root method for it has been established. If you wanna keep root, I'd wait. I'm still running stock rooted AND3 firmware/kernel. I'm looking to get the newest update up to today (I think ANG3 or something of that nature.) I'm just not taking updates yet so I can keep my root. I'm having problems with the phone freezing and restarting though so I'd like an update.

I am stock rooted with ANG3 pre-installed on my purchased S5. It runs smooth as silk if you use the method posted by muniz_ri in general. All I've done is turned off or frozen some bloatware and installed Chainfire SU 2.16.
My question was more geared towards the person who might want to go from rooted to the lastest OTA without losing data etc. I have been diving in pretty deep to the AT&T side of XDA since leaving sprint a week ago and I think the answer might have been posted by shortydoggg with the soft-bricked thread.
I was hoping someone might be able to tell me a non odin 3.09+ way to remove the freeze on my apps in the correct order to take the OTA without tripping KNOX if I wanted to do that knowing I might loose root.
I thought we might be able to follow muniz_ri and odin the one file back towelroot again after.
Basically I like stock always have, but I want root also for AdAway Titanium Backup Etc. and being a truck driver I wanted the 4.4.4 Bluetooth fix for Iheart radio.

It's hard to say what the best approach will be until the update arrives. In the case of 4.4.4, I'm rather confident that a somewhat simple method can be developed to take the update while keeping root. As for 5.0, I have some ideas none ideal but we'll see.
Is Android 4.4.4 for the AT&T version of the Galaxy S5 out? I have a Galaxy S5 AT&T phone but I don't have AT&T service. I am running Android 4.4.2 with build version ND3 is there something newer than this?
Updating to NG3
Het guys, so today I got ahold of Odin 3.09 and the NG3 update, I applied it through Odin in the AP slot and it DID NOT update my phone to NG3. My Baseband still says AND3 and kernel is 3.4.0-2178781
Tue Jul 22 13:58:46 KST 2014. Anybody have any options i can use without having to downgrade to NCE just to upgrade? LOL...Im kinda at a loss,Ive tried it in download mode twice now and no fu go.
Plz disregard my message. I'm good now and running rooted NG3.
Hello,
I have a samsung galxay s 5 running on android 4.4.2. its model number is samsung-sm-g900a. I rooted it 6 months ago but decided to unroot it when the lollipop update came out, so i would be able to get the update. I used odin and downloaded the samsung galaxy s5 stock. I have tried twice to unroot my phone but after i go through the process and download root checker on the play store, i find that my device is still rooted. Any suggestions would be greatly appreciated.

The downgrade to nce file should work fine, ive used it multiple times and been unrooted. You can load the lollipop update prerooted thlugh if you want to do it that way, which a guide for is in general.

I'm running the pre-rooted lollipop on an at&t S5 and works very well. If you unroot and get the official OTA update, you'll be stuck unrooted until someone finds a way to root again.
If you use the pre-rooted file you can go back to KitKat if you don't like the new Lollipop.
I’m guessing this has already been asked but I didn’t find a good answer for it, so I will ask here. I recently got my Verizon S6 Edge (SM-G925V) and was able to root it using Ping Pong and had no problems at all (with Super SU installed) – kudos to Keen Team. I’m on G925VVRU1AOC3 now (stock) but maybe a week ago, I started receiving a notice to install an OTA update. Should I install the OTA and if so, should I unroot my phone prior to installing the update? Sorry if I seem cautious but I've not seen this discussed about the S6 Edge and I definitely don't want to trip KNOW or brick my phone.
Thanks in advance,
UCG

If you read the q&a section on the ping pong root sub forum you will learn that thee ota cannot be installed after you have achieved root. Perhaps the best thing to do is unroot using odin then install the ota

Download smart switch onto your PC and update thru that way. It will update and you will loose root but all your data is not touched. Then you use pingpong to reroot.

Thanks @dansto82 and @Snowby123, I actually did those things. I did the ODIN thing, it didn't work (the reason I posted this thread was because I saw what to do for AT&T, Sprint, T-Mobile, but no Verizon steps). So when ODIN and factory resets didn't work, I ran the Verizon utility that comes with the phone and I did the "repair" (which downloads and installs a fresh copy of the stock ROM) and then I updated from OC3 to OE2 and that toasted my phone (and I can't downgrade either). The device actually works until it finishes booting up, then the touch screen has issues and performance is slower than my big wheel in a blizzard, but at least root is gone because I have to send it back now. The setup process runs without issue until it completes (so it isn't the physical screen). Either way, my S6 Edge 128GB OC3 phone ended up not liking the OE2 update. and I just got off the phone with Verizon and they are sending me another one. Let's hope that works.
Got my replacement phone (came with OC3). Updated to OE2 and rooted, works great. I guess caution when unrooting the Verizon S6 Edge to do an OTA.
It appears that once you install the OF1 update you can't flash back to OE2

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
Any way to root 6.0.1 G920AUCS5DPJ1 yet? Did some research but could not find a way to root for this particular build. Any update?
I've been searching for an easier method to root my phone and I'm shocked at how few options there are to root my s6. I've always been able to come across more than enough information to root all the previous galaxy phones but for some reason there doesn't seem to be an easy method (like ping-pong root or something automated) I'd appreciate if anyone has any feedback on rooting the new build after the November security patch the build number is G925AUCS5DPK1

Feedback is, there is no root for the new builds.

And is there any way to go back to old builds flashing with ODIN an old stock firmware?
I confirm: once you get the phone on a newer version, you can't downgrade it. I tried to go from 6.0.1 to 5.1.1 flashing with ODIN. The ODIN process went well, but after the phone took the older load, it got stuck in the ANDROID screen
To get it back to life i had to flash again its original stock version at 6..0.1
So the question is if there will be any developement on S6 ATT 6.0.1 to get it rooted or TWRP. RIght now it seems we are stuck. No root, No custom rom I will keep my S4 that performs like a charm with root and custom roms!

Development has been essentially dead on the ATT version for many months.

Thanks @dandrumheller for the reply
I am debating myself to try something even i know is highly possible i break the phone. I really need a rooted phone and this s6 is a replacement for my s6 given to me by ATT. If i can't get it rooted, it will sit there forever. So probably i will take the risk to try to root/load anything experimental
