[Q] Samsung Galaxy s5 won't update to lollipop

I have a Samsung Galaxy s5 that I have rooted and unrooted in order to get the lollipop update. Everytime I try to update my phone it will go through the process of an update but, after it has restarted it says that the update did not work. I am running on Android 4.4.2 and my phone is through at&t. How do I get the update to go through?

Install Samsung kies on your computer.
Use kies to back up your phone... And verify the backup integrity.
Then perform a full wipe on your phone, and use kies to upgrade firmware to lollipop. After upgrade do another full wipe for good measure.
Now use kies to restore your backup.

Stock Att Galaxy S5 stuck on 4.4.2

I try to check for new updates and it says I am current, I tried Kies as well. I would like to root but I installed the towelroot apk and it says it isnt supported. What can I do?

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.

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

SM-G800F - Samsung Galaxy S5 Mini - Update after rooting?

Hello!
Is there a way to update your device through the official updates of Samsung to the newest updaate?
I rooted my phone using the "Root Samsung Galaxy S5 mini SM-G800F using Odin" guide on AndroidMTK. (Search it on google, first link it is probably) but now it says even after unrooting that I have modified files on my phone and making it unable to root.
I want to download the OTA Updates because it contains Android 5.0, doesn't matter if I have to unroot because I don't like my rooted device anyway.
Is there any way?
Please help.

I found that the device will update OTA regardless of root. Root is broken after the update, but that's all.
The message about having a modified system only appears when no update is available. If there is an update, it will start downloading and install.
Others may be able to confirm/deny this behaviour, but that's how it worked for me.

S5 rooted help

current software 4.4.2 what's the best way to update to update the software to latest new to root

What phone model? G800F, G800H, etc?
Most versions have official Lollipop from Samsung, you can update it using OTA, no root needed and it won't trip Knox warranty. If your model doesn't have a version for your particular country then you can use Odin to flash a compatible version (same model, another country) and it should keep your warranty.
If you want Marshmallow then there is no official version yet. You can get a custom ROM, then you will need TWRP either using Odin or rooting first.

Thanks for the reply ! I'm a idiot ... I have an s4 mini lol

If you meant GT-i9195 or anything other than G800-something then probably you're in the wrong forum, you will get better help in the appropriate forum for your device.
Secondly, if you've used KingRoot then either stick to KingUser app (SuperSU won't work) or you need to replace it completely either using an app or some script, both don't work always...
