How to Update At&t Galaxy S6 to Nougat

Samsung started updating its flagship devices to Android Nougat very recently. At first, it updated the S7 and S7 Edge to Android Nougat. Carriers like At&t, Verizon, T-Mobile and Sprint also followed Samsung’s footsteps and updated their branded S7/S7 Edge to Android Nougat. Samsung rolled out the Android Nougat update for the Galaxy S6 and S6 Edge right after after that. The update first of all came out for the global variants of the phones. It is now the turn of network carriers to start updating the phones to further version of Android.

At&t has taken the lead in this regard as it turns out to be the very first carrier to update its S6 to Nougat. The update brings all goodies you heard about for the previous devices. It updates the UI of the phone, brings a new UI for notification panel and toggles, new icons in the toggles, new icons for applications and also the new settings applications. Apart from the UI elements, the device gets a better battery life and also a higher performance in this new Android Nougat update.

At&t is currently sending out the update through OTA updates. You can check your device’s about device > software section to see if an update is available for your Galaxy S6 which falls under the umbrella of At&t. XDA member sand_bit has come forward to help the At&t S6 owners and posted out the OTA update files over the forum. Users can get their hands on these files and flash them manually to update the phone without waiting. The method is good for those users who have an At&t Galaxy S6  outside the region or those who are unable to capture this update.

If your Galaxy S6 G920A is currently running DPK5 firmware, you can skip the Andorid Marshmallow OTA.zip files given below and start flashing the files of Android Nougat in the following manner: DPK5 —> EQA8, EQA8 to EQB8, EQB8 to EQC9.

If your device is running on DQB3, you will flash the DQB3 —> EQB8 or the DQB3 to ECQ9.

If your Galaxy S6 is running on Android 6.0.1 Marshmallow DPJ1 firmware, you will have to flash the Android Marshmallow files as well in the following manner: DPJ1 to DPK1, DPK1 to DPK3, DPK3 to DPK5, DPK3 to DQB3 or DPK5 to DQB3.

If your Galaxy S6 is running on Android Lollipop, you will download the DPJ1 Odin files and flash them using this guide. The guide is for Galaxy S7, but you will follow the same procedure to flash the DPJ1 firmware on your At&t Galaxy S6.
