Update AT&T Galaxy S5 Active to Lollipop, Root It and Enable WiFi Tethering

158

The Android Lollipop currently occupies a meager 3% of in the official OS distribution chart. To a great extent, the laziness of most of the OEMs and carriers in pushing new updates is responsible for the poor distribution. When it comes to releasing major OS updates, especially for a little older devices, Samsung doesn’t have a very good track record.

Lollipop is out for more than 6 months now and there are still so many devices waiting to get it. For the past few weeks, the Korean giant has been pushing the Android Lollipop to some of its older flagships. While the carrier-branded devices have to wait for months before they get the major updates, the international variants receive them pretty earlier.

Anyway, the US models of Galaxy devices have now been receiving the Lollipop update in quick succession. If you own the AT&T Galaxy S5 Active SM-G870A, it’s your moment. AT&T has started rolling out the Android 5.0 update with build number OC5. The size of the Lollipop OTA is 1434.38 MB and if you have not received it yet, you can request it manually by going to Settings> System> About device> Software update.  If you still haven’t any luck, you can flash the OTA Zip file via stock recovery.

If you are addicted to enjoying root privilege on your AT&T Galaxy S5 Active SM-G870A, we also have the pre-rooted Lollipop firmware for your phone that you can flash right away. Thanks to muniz_ri for his commendable work for the AT&T Galaxy devices!

Update AT&T Galaxy S5 Active to Lollipop (no root)

Note:

To be able to install the Android 5.0 Lollipop OTA package on your AT&T Galaxy S5 Active, your device must be fully stock (no root) with Android 4.4.4 firmware running on it. If you phone meets this requirement, follow the steps provided below to upgrade to Lollipop. The procedure will not trip the KNOX Warranty Void counter. If you want root privilege on Lollipop, skip to the FireFlash method described below.

Instructions to Install the OTA

  1. Download the Lollipop OTA package and rename the file as “update.zip”: 2400258.cfg
  2. Copy the update.zip file to the external SD card of your phone.
  3. Enable USB Debugging on your phone as a precaution.
  4. Turn off your device and reboot into the stock recovery. To do so, hold the Volume Up+Home+Power keys together while the device is switched off. As soon as you see the Samsung logo, release the Power key and keep the other two keys pressed until you see the recovery menu.
  5. Using the volume keys, scroll to “apply update from external storage” option and select it by pressing the Power key.AT&T-Galaxy-S4-stock-recovery
  6. Navigate to update.zip package and select it.
  7. Confirm installation when prompted.
  8. When the file is flashed, go back to the main menu and select “reboot system now” option.

Done! Now you need to wait patiently for about 5-10 minutes before your AT&T Galaxy S5 Active boots up and becomes usable.

  • Daniel Lee

    Did you figure it out?

  • Khaled Shaath

    Could you please post a tutorial on how to update Galaxy S5 Active G870A to Marshmallow? It has been released by AT&t, but I am not able to find the official Marshmallow rom and I am worried it may brick my phone. Please help with this.
    Thanks

  • Ola

    So. As mentioned around the comments with others, I’m having issues with the first Odin steps installing the G870AUCU1ANE4_G870AATT1ANE4_G870AUCU1ANE4_HOME.tar.md5. I continue to get a fail with the error “SW REV CHECK FAIL : [aboot]Fused 2 > Binary 1”
    My phone currently has Android: 5.0
    Basband version: G870AUCU2BOF2
    A year ago it appears there was a comment stating that rolling back to the 4.4.2 that this .md5 contains isn’t possible. Is that truly the case and is that the reason i’m getting the fails? Is there anything I can do to resolve this and get this root done?
    Thanks for any help.

  • Claussim

    Hello, friend. I have a question. I have read that Samsung S5 custom ROM’s will work on a S5 Active, just that the Active button would not work. Should everything work fine? In some old post supposedly if you tried installing a ROM on an AT&T variant it would disturb your service, but others say that the regular S5 ROM’s should work as I stated earlier. Do you have any imput you could give me? Please and thank you!

  • Ehtesham Ahmed

    Hi Rakesh !
    I have S5 active SM_G870A running 4.4.4. I want to upgrade my phone to lollipop (No Root)
    Your first method is correct? Should I consider method no 1?

  • Thomas Cavanagh

    You android version must be 4.4.2 or below. Flash G870AUCU1ANE4_Full_Odin.rar with Odin first

  • Felix K.

    Hi,
    thanks for this great tutorial!
    My phone now works fine with Android 5.0 (LRX21T.G870AUCU2BOF3) and OC5 Bootloader, but unfortunately it does not recognize SD cards 🙁
    I missed to try before root/update… is there any way to check whether it is a software or a hardware problem (diagnosis of the slot)?
    Cheers
    Felix

  • Joán

    Hi, you can do a tutorial for no root users to update from OC5 to OF2 -> OFC -> OJ3 (5.1.1) please or share the .cfg files to do it!

  • Viswanath Ellappan

    I am using s5 at&t bought in usa and unlocked at present using in india.I have a version 4.4.2 how to update to lollipop.I don’t have 4.4.4 version can I update by the instructions given by you. Please help

    Viswanath

  • Ichbin EsNicht

    Dear Mark, it doesn’t take a PDH. I followed the instructions and it worked like a charm in one hour. But I am a IT Professional :). Everyone else can do it!

  • Glad to know it worked for you! Thanks for the appreciation, Ichbin! 🙂

  • Ichbin EsNicht

    Try the rooted option with the tar.md5

  • Ichbin EsNicht

    Hi Wilfried, we are talking about the S5 Active AT&T Version here only!

  • Ichbin EsNicht

    Yes, if you follow the instructions above, you will be downgraded to 4.4.2 and then you can do the rest.

  • Ichbin EsNicht

    Hi Sparky, if you follow the instructions EXACTLY, 4.4.2 (G870AUCU1ANE4_G870AATT1ANE4_G870AUCU1ANE4_HOME.tar.md5) will be first installed and from there you can go to 5.0. When I look at your 4.4.2 that you tried to install, the name is different “…NEW…”. Get the 4.4,2 from the link above.

  • Ichbin EsNicht

    Dear Rakesh, you are my HERO!
    It worked like charm. NOTE: If your device gets stuck on the AT&T logo: on the 4.4.2 install, I had to do a factory reset via the “Volume-UP + Home + Power Buttons” – on the 5.0 install, removing the battery was sufficient. FINALLY, I am rooted after reading many posts the the AT&T SM-G870A cannot be rooted because of encryption. Now I can get rid of all the AT&T BloatWarez.

    Thank you sooooooooooooo much 🙂

    IT WORKS !!!!!!!!! THANK YOUUUU :)))))
    But is not in Portuguese, there is a way to install the Portuguese language?
    google.maps directions are giving in English and the street names became so strange that is difficult to understand.

  • Sparky McBiff

    I tried that already file several times with mine (using Odin) and it didn’t work.
    (It just said “Fail”)
    It got stuck on the “downloading” screen and I had to recover the phone by just removing the battery for a second.
    I just bought this phone and it has the AT&% Android 5.0 version on it which I’ve yet figured out how to get rid of.
    Hopefully soon someone will have a fix for it.

  • Sparky McBiff

    I just recently bought this Galaxy S5 Active that already had Android 5.0 on it and I’ve been trying to get this AT&T crap off of it for a few days now but have been unsuccessful.
    I’ve got build version: LRX21T.G870AUCU2BOF2 and have been using Odin to try to either downgrade to 4.4.2 (in order to then go to 4.4.4 and then either root that or load a 5.0 root).
    I’ve also tried creating and flashing .img files using Unified Android Toolkit and Odin as well but so far I’ve only managed to recover from either getting stuck in a booting loop or after getting a “fail” with Oden and stuck on the downloading screen on the phone (which I then get out of by removing the battery and rebooting).
    I want this AT&T garbage off my phone and I’m not going to give up.
    If I can at least get 4.4.2 on there I should be able to find my way from there.
    When I did a “factory reset” it actually took me back to 5.0!

    (I’m Canadian so we don’t have AT&T up here, but since buying this
    phone I’ve discovered that the “A” in AT&T obviously stands for
    Assholes).

    I’ve always had HTC phones before and to be honest I’m not impressed at all with the Samsung layout and am hoping that rooting the darn thing will at least make it somewhat more tolerable.

    Any idea (or link that doesn’t go to annoying Mega) where I can find the 4.4.2 (or 4.4.4) file that I can try loading?

    Thanks.

  • idreis bari

    thanx!!!! i really cant thank you enough bro!!! my phone didnt update, and i tried everything else, and this was the only tutorial that worked. it wiped the info off my phone though, but i had backups, so i am fine. but again thank you so much, and keep doing what you do!

  • Jack Collins

  • Martin Tříska

    Hello, I have my S5 active without root already on lolipop 5.0. From what I read here, one cannot root that. Would it be possible to flash older KitKat via Odin and then proceed from there?
    In other words, is it possible to downgrade by flashing G870AUCU1ANE4_Full_Odin.rar through Odin?
    Thank you!

  • Jorge Cruz

    Thank you, I upgrade from OC5 with root to OF3 root, data in the internal memory are not lost, only applications, Re-activation lock is not lost 😀

  • Which file did you download?

  • Jesse Flisch

    Is there a certain program I need to download the file with I just downloaded it with the default Internet app and I moved it over to my SD card but when I load up stock mode it’s not there

  • Looks likes the Lollipop bootloader can’t be downgraded. You’ll have to wait until a working root for the AT&T S5 Active surfaces.

  • Jordan

    I downloaded the mega link but every time i tried to flash it Odin would fail and the other link is in another language and i don’t think that google is doing a good job of translating what it wants me to enter to register.

  • Jordan

    I don’t mind paying a little bit for a one time thing but not a good amount for a month with one download.

  • Jordan

    I ask this because through the normal sites like sammobile and samsung updates they make the download take like 24 hours for me for free version but i don’t want to pay weekly or monthly for something I might only use per update or new phone. Do you know where I can not get ripped off?

  • There’s no working root for Lollipop at the moment. You must find a way to downgrade to KK, root the device and try the Flashfire method from above.

  • Jordan

    I already have 5.0 installed and just want to root, you really don’t specify how I can just root my current version.

  • Set your phone’s date prior to 9/1/2015, reboot the device and try again.

  • Chayon

    hey man FlashFire does not wanna open up can u please help me how to fix this

  • Robert Edger

    I thought OF2 already required the OC5 bootloader?

  • Glad to know you made it yourself.

  • If you install the ROM from above, you update the bootloader too.

  • Robert Edger

    If I am running OF2 currently, do I need to update my bootloader, or just the ROM?

  • Raj Chacko

    Never mind, I was able to download a stock version of the firmware and flashed it back.

  • Raj Chacko

    Hi Rakesh, I accidently loaded G900A firmware instead of G870A no my Galaxy S5 Active, Is there a way to get the phone to flash with the correct firmware? I am stuck in ODIN mode. Tried factory reset keystroke combo but phone is stuck in ODIN mode. Any help would be much appreciated

  • jared garcia

    can i do it again or will it mess up my phone

  • jared garcia

    it does have 4.4.4 even after it updated

  • It’s because your phone doesn’t have the required base firmware (Android 4.4.4) for the OTA.

  • jared garcia

    well i did it but it deleted every thing on my phone

  • Rename “24000258.cfg” as “update.zip”

  • jared garcia

    rakesh when i download the ota file it doesnt show as a zip file but just a file named 2400258.cfg

  • jared garcia

  • marin turshinka

    hi i have done the process and everything seems to be ok but when i try app that need root like xmodgames, gamecih, etc it says that i am partially rooted than the su binary needs to be upated

  • For tethering on Jelly Bean, you can try FoxFi. If you want hotspot on Android Lollipop, go with the FireFlash method from above.

    Install the NE4 ROM, use Towelroot to gain root, install FireFlash and follow the guide from above.

  • Joel Brandon

    Thanks, Rakesh, for the easy to follow process and – most importantly – accurate and up-to-date links for FlashFire beta, rooted ROM, and the tethering mod. The links saved me lot of time looking for the files.

  • Restore the stock 4.4.2 firmware, root it with Towelroot and try again.

  • Cris Hernandez

    Can you help me out? I did all the steps and the phone has been booting up for about 30 minutes

  • NE4= 4.4.2.

  • Sergey Arustamov

    Do i need to downgrade to 4.4.2 or just flash NE4 straight to root my phone via odin?Thanks!

  • Yes, you can downgrade to NE4, root it and then you can proceed with the rooted Lollipop.

    Downgrading to 4.4.2 has been confirmed below by lhop.

    So question, if I flash the stock 4.4.2 firmware that you have there, will I be able to do OTA updates? Because I don’t mind rooting but I would rather just OTA instead.

  • Interesting observation , Mark! I certainly am a PHD. in English literature but not in Android. I have only tried to explain things in a simple way to the best of my capacity. I am sorry that I failed in that!

    Between, can you mention a few of the confusing things? It will help me improve on describing things in future. Thanks!

  • Mark Roberts

    I have looked at this how to page for several hours and would like to say that who every wrote these instructions could not have a PHD in confusion and work for the government and made this subject anymore complicated and difficult. LOL

  • PH Mompeyssin

    Did the update, worked well! But the phone is no more recognised in RNDIS!! How do I get that back?!

  • Hi, the link has been updated!

  • You must have root to use FlashFire method. Since you’ve already upgraded to Lollipop, I don’t think you can do that.

    However, since we’ve confirmation that you can downgrade back to Android 4.4.2 (see Ihop’s comment below), you can start from the scratch. Go back to 4.4.2, root with Towelroot and then you can go with FireFlash.

  • Yes, the file was reuploaded after I gave you the link.

    The File you linked is 404, but is it the same as this?: https://www.androidfilehost.com/?fid=23991606952592939

    So there is a root for at&t galaxy s5 already running android lollipop? I really want to root this phone, but I can’t find stable enough info about the 900 android l root. Help please

  • prakash

    you need 4.4.4 ota zip file and flash it with Sideload then you will on 4.4.4 then flash 5.0 zip in stock recovery….that’s it….

  • Which method do you want to go with? Also show me your recovery pic.

  • Ihop

    So I saw this too late and started, effectively creating a bootloop. I factory reset, so now I’m back at 4.4.2 and yet when I try to repeat the process the option isn’t available in recovery mode. Any ideas as to why? If possible, I’d be happy with an alternative lollipop root for the S5 Active if you know of one.

  • Anthony Zheng

    You get that error if you tried to mess with the stock ROM of your android OS beforehand. The only solution possible would be for you to visit a nearby Bestbuy and get your phone upgraded to 4.4.4 at the Samsung center. They might just upgrade your phone to Lollipop but that’s better than having 4.4.2 right?

  • You don’t need that any more. The guide has been updated. Just use this file: https://www.androidfilehost.com/?fid=23991606952591471

  • Austin MPG

    G870A_OC5_Stock_Partitions.zip seems to be missing…. 🙁

  • Since you are already on Lollipop, you won’t be able to gain root. I am not quite sure if you can downgrade back to NE4 or not.

  • Ihop

    Slightly confused. S5 Active currently running lollipop but i want to root it. Do i just use towelroot or do I go through the steps with FlashFire? Also, when does G870AUCU1ANE4_Full_Odin.rar come into play? Sorry in advance, my first time.

  • foxrevolution

    It might be worth noting the root method wipes the phone. I would use Titian Backup first to backup your apps and settings.

  • Donny Huglin

    didnt work device not supported

  • Use Towelroot: http://www.droidviews.com/root-att-and-verizon-galaxy-s5-without-voiding-knox-warranty/

    And when you get rooted, follow the steps under the following head “Install Rooted Lollipop Firmware on AT&T Galaxy S5 Active” from above.

  • Donny Huglin

    can you please link me on how to do this i really want lollipop but i am running on 4.4.2 🙁 help me x

  • Yes, you need to have Android 4.4.4 base for the OTA. If you got 4.4.2, root it first using Towelroot and then go with the Fireflash method.

  • Donny Huglin

    its says in the requirements that you must have 4.4.4 will this matter if i am running 4.42?? please some one help me

  • m Holden

    I appreciate the advice, I wondered about the tether and would have loved to use it but I figured it was geared to att and wasnt sure how it would work with t-mobile. Its not a huge deal since I can still tether using other apps but was hoping to unlock hotspot mode. thanks again

  • Then you can install the rooted firmware using FireFlash.

  • Updates usually don’t affect SIM-unlocked status. Just avoid flashing the tethering mod and it might cause issues since you’re not using an AT&T SIM.

  • m Holden

    My phone is unlocked and I am using it on t-mobile. Can I update and
    root using this method or will I lose the unlock or will it cause any
    other issues I am missing? I would like to update and root.

  • francisco

    No, that’s the problem, no OTA updates, i need a AT&T sim, or manually update.

  • Had it been available by default, there wouldn’t have been any need for the mod.

    P. S. – I don’t own this device.

  • Jeremy Oakes

    Doesnt ATT already provide free wifi tethering with GS5 Active?

  • You can request the 4.4.4 OTA in Settings> About> Software update. Are you using the phone in the US?

  • francisco

    Mine is running 4.4.2, the OTA requirement says 4.4.4., where can I get the firmware for 4.4.4?

  • Is your device on G870AUCU1ANE4? Check it under Settings> About.

  • Justin Pulley

    Towelroot fails on my S5 active; it says device not supported.
