[AT&T Samsung Galaxy S7 Guides, News, & Discussion] Jimmyvb98:
If you have a S7 Edge, you have to use this thread.

First of all, the credits of the second option from the tutorial below goes to [MENTION=4644140]lirex[/MENTION], he is the one who created this tutorial in the S6 Active forum, I only edited it for the S7. This is only for the AT&T model of the S7, not for international or other models, don't try it cause you might brick your phone! This update hasn't been tested yet, so if you don't like bugs or if you r phone is important for work, don't update to an unreleased version, as there may be some bugs in it, which can cause sudden reboots or battery drains.

Second, English is not my native language. So if I made a mistake, please let me know. :)

Keep in mind you are updating your phone to an unreleased build. I can't say whether it's stable or not, because the update file has just been found. New update files will be released every now and then, but it is not possible to update from an unreleased build to another unreleased build. Once you're on Nougat and another update appears online, you have to flash back to PI2 and update it again.

If the update or sideload ends up failing, flashing the stock firmware with Odin will resolve this. But just be sure to follow all the instructions, AND ALWAYS BACKUP YOUR PHONE. Your phone will factory reset after the update.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

IMPORTANT: Flashing WILL WIPE EVERYTHING SO BACKUP FIRST. (I'm not responsible for anything that goes wrong, but this worked for everybody so far). You can use this regardless of your firmware version. Just make sure to sideload the proper file for your current firmware!

Prerequisites: Before you proceed prepare these necessary things as follows so you will not screw-up your phone:

• Create a back-up with Smart Switch of all your personal data, like: Contacts, Messages, Applications, Pictures and Videos, so that you will not lost it just in-case something might went wrong after the update.

• Make sure that your Galaxy S7 battery is fully charged to ensure stability and to get rid of power failure issues while updating.

• TURN OFF the Reactivation Lock - Go to Settings > PERSONAL > Lock screen and security > Find My Mobile and log in your Samsung Account. Then uncheck the Turn Reactivation lock on. This is only needed if you already turned-it-ON, from which you cannot modify the system when it's turned-ON.

• If you disabled some system bloatware manually or with a third party software, make sure everything is enabled again.

Option 1: Flash via "Apply update from SD card".

1.) Download the firmware packages from the official AT&T Update server to your PC:

To make it easier for everyone, all update files have been uploaded to Google Drive, thanks [MENTION=911399]siacono[/MENTION].

v2 (G930AUCU2APD1) to v3 (G930AUCS2APE1) update file

v3 (G930AUCS2APE1) to v4 (G930AUCS2APF21) update file

v4 (G930AUCS2APF2) to v5 (G930AUCU2APG1) update file

v5 (G930AUCU2APG1) to v6 (G930AUCS2APH1) update file

v6 (G930AUCS2APH1) to v7 (G930AUCS4API2) update file

v7 (G930AUCS4APK1) to unreleased (G930AUCU4BQA4) update file

Somehow I can't get the links of the v7 (G930AUCS4API2) to v8 (G930AUCS4APJ4) and the v8 (G930AUCS4APJ4) to v9 (G930AUCS4APK1) updates, so you have to update those OTA.

If you prefer downloading them from AT&T's servers, here are the original links: (NOT working anymore)

** You will see SERVER ERROR 403 or ERROR 404: NOT FOUND, that's because you have to use a download manager program like this (it's free), otherwise you won't be able to download those files. **

-> v2 (G930AUCU2APD1) to v3 (G930AUCS2APE1) update file

-> v3 (G930AUCS2APE1) to v4 (G930AUCS2APF21) update file

-> v4 (G930AUCS2APF2) to v5 (G930AUCU2APG1) update file

-> v5 (G930AUCU2APG1) to v6 (G930AUCS2APH1) update file

-> v6 (G930AUCS2APH1) to v7 (G930AUCS4API2) update file

-> v7 (G930AUCS4APK1) to unreleased (G930AUCU4BQA4) update file

Somehow I can't get the links of the v7 (G930AUCS4API2) to v8 (G930AUCS4APJ4) and the v8 (G930AUCS4APJ4) to v9 (G930AUCS4APK1) updates, so you have to update those OTA.

2.) After you download the right update, right mouse click on it, select "Rename" and add ".zip" at the end of it. Then, put it on the root of the SD card. If you have an empty one, use it, just to prevent the SD card will be formatted too.

3.) Reboot the phone into recovery. Turn it off and wait a minute for it to completely turn off. Hold down Volume Up + Home + Power until you see a little Android guy. It will say Applying System Update or something like that possibly, and just let it do it's thing until a menu comes up.

4.) Select "Apply update from SD card". You can scroll using the volume buttons and select using the power button.

5.) Wait patiently. The firmware files over 1 GB can take over 30-40 minutes. It's okay.

6.) The phone will reboot and will hang at AT&T logo. This can take another 10 minutes, just wait until it's done. Now repeat steps 1 to 5 until you're on the latest firmware (Android Nougat, unreleased version).

Option 2: Flash via "Apply update from ADB".

If the first method somehow doesn't work for you, you can try it using your computer. Prepare a Windows PC, sometimes it doesn't work on a Mac.

1.) Download the firmware packages from the official AT&T Update server to your PC:

v7 (G930AUCS4APK1) to unreleased (G930AUCU4BQA4) update file

Somehow I can't get the links of the v7 (G930AUCS4API2) to v8 (G930AUCS4APJ4) and the v8 (G930AUCS4APJ4) to v9 (G930AUCS4APK1) updates, so you have to update those OTA.

3.) Select "Apply update from ADB". You can scroll using the volume buttons and select using the power button.

4.) Make sure you have ADB and the proper drivers installed on your PC:

-> ADB & Drivers installer

5.) If you're on firmware v7 and you're going for the Nougat update the update file is called "SS-G930AUCS4APK1-to-U4BQA4-UP".

Put it in the ADB folder

. You can rename it to anything easy to remember like "FIRMWARE".

6.) In the ADB folder, hold SHIFT + right mouse click and choose "Open command window here". Then type the command "adb sideload FIRMWARE" (where FIRMWARE is how you named your file). If you have any problems check the Troubleshooting Tutorial at the end of the post.

7.) Wait patiently. The firmware files over 1 GB can take over 30-40 minutes. It's okay.

8.) The phone will reboot and will hang at AT&T logo. This can take another 10 minutes, just wait until it's done. Now repeat steps 1 to 5 until you're on the latest firmware (Android Nougat, unreleased version).
