Install Android Nougat on AT&T Galaxy S6/S6 Edge (SM-G920A/G925A)


Almost all variants of the Galaxy S7 have already received the Nougat update and now the Korean giant seems to have turned its eye to our good old Galaxy S6. While the international models of the phone got the Nougat OTA more than a week ago, the users of the AT&T variant have not started receiving it.

Since the full Android Nougat firmware for the device is not available anywhere, you will have to flash the OTA zip packages depending on your current firmware version in incremental order. In this tutorial, we’ll see how we can install Android Nougat on s6.

If you have not been able to get the official Nougat OTA on your AT&T Galaxy S6 (SM-G920A) or S6 Edge (SM-G925A), you can update your phone’s software by installing the OTA zips provided below.


Please note that your AT&T Galaxy S6/S6 must be fully stock to install the OTA. Though we have taken utmost care in laying out the installation steps, a successful installation depends on how you follow them. Proceed at your own responsibility and don’t go ahead if you don’t understand at all what you are going to do.

Getting Prepared

Before you proceed, here’re a few preparations you need to make so that things go smooth for you.

  • Backup all your data and apps using Smart Switch as a precaution.
  • Go to Settings> Personal> Lockscreen and security> Find my mobile and turn off Reactivation Lock.
  • Go to Settings> Developer options and enable USB debugging (this is just as a precaution).
  • If you have disabled any system apps, please enable them from Settings> Applications or the OTA file installation might fail.
  • Charge your Galaxy S6 so that it has 60% battery level at least.

    The thing is I have a G920A AT&T with the baseband version (G920AUCU3CPD5 Android 6.0.1) and I really would like to know if I have to install first G920AUCS6DQC1 directly with Odin even though is not the same baseband and then from G920AUCS6DQC1 to U6EQCF Nougat update OTA zip with ADB, and sorry I’m new to all of this and thank you.

  • Sai Pranith

    Thanks a lot Rakesh! Achieved in first attempt 😀

  • Ratna Yudhiyati

    I tried to update Nougat by using Odin for my SM-G920A.
    I followed the instruction, flahed the firmware, and everything worked well. Odin said it was successfull, yet my Android remains 6.0.1. I don’t know what the problem is. Will try the OTA one later …

  • Mian Awais

    same here. please help.

  • Messi10

    hello I downloaded the “G920AUCS6DQC1- Full-ODIN-firmware” and updated but still its 6.0.1 on my phone ???

  • Ananta Bastola

    I have Baseband Version of: G925AUCS5DPI1 ! which firmware to download?

  • Great, enjoy!

  • Dimov Daniel

    I’m already done, the phone works perfect and faster. Thanks!

  • It shouldn’t take that long. Disconnect the phone, reboot it and try again.

  • Dimov Daniel

    Hello from Bulgaria! I’m with SG-G925A and I do all steps with Odin and all worked perfect. Now I’m on adb mode and waiting from maybe 30-40 minutes… my phone shows Unpacking new files… and on the command window shows that the process is on 96%, but it is 96% for more than 20 minutes… Is it normal? I mean is it takes too much time or its fine? Thanks!

  • Glad to know! You’re welcome!

  • Mobilexr

    Successfully updated on first attempt 🙂
    Thank you 🙂

  • What error do you get?

  • Enrique Sanchez

    G920AUCS6DQC1-to-U6EQCF is not like the other files, it won’t let sideload it.

  • Oren Cohen

    everything worked fine,
    Many thanks !!!

  • rmunizcruz

    Yes!! Thanks Oren. I am updating the phone right now and everything seems normal.

  • Oren Cohen

    found the issue, its not “removing” the rar extension, but extracting it, the valid md5 files are in the rar.
    do it for all files.

  • Oren Cohen

    same problem here 🙁

  • rmunizcruz

    I already try that several times too and Odin don’t even let me put the files.

  • Okay. Try adding “.md5” after .Tar in all 4 files and try installing again. It worked for me.

  • rmunizcruz


  • Did you remove the .rar extension from the firmware files?

  • Download and install the firmware:

    Then install the QC1 to QCF Nougat OTA zip.

  • PK3 to QB8 is an OTA zip file. Odin detects only .tar or .tar.md5 files.

    OTAs must be installed using ADB sideloading method described in the tutorial.

  • So, do you need any assistance?

  • I mean that after installing the firmware successfully you have to flash or install that Nougat OTA zip file via ADB Side-loading. You can find the instructions for that same above.

  • Oren Cohen


    What do you mean by “flag the Nougat OTA”, assuming the firmware installation ended successfully, so I need to do it, is it the adb sideloading section, doe it going to wipe my data?


  • Hi Oren, “flag” is a typo. I actually meant flash or install. First of all, Install the QC1 firmware that is the latest Marshmallow release for the device. After that you need to install the QC1-QCF OTA zip file as described in the guide.

    Flashing the OTA through ADB will wipe your phone’s data so don’t forget to backup your device first.

  • rmunizcruz

    My baseband is G25A. I already try a couple of times the both ways and it didn’t work. The method of Odin stays on “File Analysis” and the adb sideload method print the message “Total xfer: 1.15x”.

  • Nick

    Downloaded pk3 to qb8 and Odin won’t find the files and add says can’t read the file

  • Nick

    My baseband version is G920AUCS5DPK3. What file/files do i need to download to get my S6 on Nougat?

  • enrique papierman

    Nothing yet. I’m from Argentina, my english is not so good and I don’t understand the istructions 100%. I mean that I get lost trying to understand.

  • What happened?

  • enrique papierman

    Ok, That’s were I get lost…

  • Yes. After installing the firmware files , just flag the Nougat OTA using the instructions above.

  • enrique papierman

    Hi, my baseband is G925AUCS4CPG1. All I´ve got to do is install the 4 files via odin and that’s all? Thanks Rakesh!

  • Glad to know, Chris! 🙂

  • Chris

    Finally I did!
    Thanks Rakesh!

  • Just updated the guide. Do as described and you’ll update your phone successfully.

  • You’ll find it in the tutorial above.

  • Hi, I just updated the tutorial. You also need to install the Nougat OTA file.

  • Umair Ahmed

  • Chris

  • Chris

    didn’t work again 🙁

  • Sounds weird! Try performing a data factory reset via stock recovery and flash the firmware again.

  • Juan

    I attempted to do this with the updated link and all it did was re add 6.0.1

  • Chris

    Hello Rakesh i install this but I’am again in 6.0.1 ne Baseband change in G920AUCS6DQC1. Now how to get Nougat. can you send me a download link for Nougat firmware

  • Alvin

    Hi Rakesh. How if my Baseband version is G920AUCU3CPD6? Can I still be able to upgrade it?

  • Chris


  • It should be out within a week.

  • Chris

    When the update will come automatically? Date?

  • You can try that but you would need an USB OTG for that. It would be better if you start from the scratch. I mean re-flash the PK5 firmware in Odin followed by the OTA update zip via recovery.

  • Saad Ali

    Can I try reinstalling it through apply update from sd card’? Through placing the zip file in storage?

  • Saad Ali

    internet is absolutely working because it logs me in using google account.

  • Sounds weird! Then try reinstalling the firmware.

  • Saad Ali

    I have a working internet, tried both wifi and data but its stil same, even tried factory reset, Also tried without sim.

  • Make sure you have a working data/WiFi connection.

    You can also try a data factory reset via the stock recovery:

  • Saad Ali

    I have successfully done everything but the setup wizard is not finishing after the last ‘Just a sec’ screen. Any help will appreciated.Thanks

  • Just replied above. Just install the files I mentioned above.

  • Install the PK5 firmware:

    And then, install

  • Ricardo Pontes

    I also want to know my phone is the same

  • julio

    I have a At&T S6 edge wih PD6 wich firmware is the correct?

  • The C&P Gaming

    Thank you.

  • Downgrade to G925AATT5DPK5 firmware and then install PK5 to QC9 OTA zip.

  • The C&P Gaming

    What one do I install if I have At&T S6 edge with baseband G925AUCS6DQC1? Plz help.

  • Yes.

  • Roberto Mata

    this is the right one? have da same galaxy model with base band G925AUCS4CPF1.

  • Hi Abdul, just updated the guide.

  • Abdul Samad
  • Abdul Samad

    Yes, But thanks brother….the problem is solved now….what I sorted out is that the issue is not with the update packages….rather its an ADB server support issue….the platform tools you provided in the link does not support either bootloader version 6 or the android 7 version itself….so I tried the minimal ADB fastboot. And it went with success! The same issue is with the S6 edge plus at&t another guy is experiencing on another forum on Droidview…better help him out also….

  • Okay. Is you phone on PK5 firmware?

  • Abdul Samad

    yes it is fully stock, and the device status is official, no system apps were disabled since i factory restored the device before operation. All previous links for android marshmallow update went successful until this large update firmware was attempted. ADB stopped responding to work and the error was generated. I tried it on a different system with different OS. Same error.

  • Ernesto Goris

    And wich one OTA I have to install? For the s6 edge there are 2

  • Make sure your phone is fully stock and also that you have not disabled any system app or bloat.

  • Install the PK5 firmware first:

    And then you can install the OTA.

  • Abdul Samad

    Please help, the updates of Nougat dont work.
    I tried both of these firmwares:

  • Ernesto Goris

    i have a At&t S6 edge (sm-g925a) with base band G925AUCU4DPH5, can i flash it?

  • That was a mistake. Edited. Use the ADB method.

  • Shailendra

    Your “Getting Prepared” steps says: Make sure you have inserted an external micro SD card into your phone.
    But Galaxy S6 does not take external SD card. How do I install the OTA for Galaxy S6?
