The latest Android 7 Nougat official security update is the Autumn 2017 one, and you can flash it on your Galaxy S7 Edge phone starting from today.
If you do not want to wait until T-Mobile pushes the new firmware files in your region, then you can manually complete the new update. These updates are being rolled out in stages for everyone, which means that not everyone will get them at the same time.
This guide is useful in case you wish to restore your phone to 100% stock Android, too. The ODIN app will be used for the update process, and Odin is capable of flashing the new Nougat OS over a custom ROM, too.
Check the following guidelines before the update:
- this guide has to be applied only for the T-Mobile Samsung Galaxy S7 Edge phones.
- the model number of your device has to be the SM - G935T.
- don't use the tutorial for any other different devices.
- download the Samsung USB drivers from here and install them on your computer.
- these will allow ODIN to easily detect the phone when connected.
- for the update process you will use the ODIN 3.12.3 tool.
- for ODIN to work properly with your computer you will have to install the above drivers, and to enable USB Debugging from the phone's Developer Options menu.
- the Developer Options might be hidden, go to Settings> About Device> Software Info and tap seven times on the Build Number text.
- return to Settings, as Developer Options will now be listed in there.
- Open Developer Options and find USB Debugging to enable.
- you can flash the new update over rooted Android firmware, but you need to know that root access won't survive the update.
- any custom Recovery you might have flashed will be replaced with stock Recovery.
- Odin can install the Android 7.1.1 update over a custom ROM, too, but you have to Factory Reset the phone after the update is done installing.
- the Factory Reset wipes clean system partition, it removes the custom ROM and it allows the Galaxy S7 Edge T-Mobile device to boot in normal mode.
- if your device runs 100% stock Android firmware, then you can continue straight to the next part of this post, and learn how to manually complete the update.
- read the whole post and do not skip any steps.
- this tutorial has to be applied only by advanced users, we cannot be blamed in case you brick the phone nor in case you lose any data files.
How to install Android 7.0 Nougat Autumn 2017 Official Update for T-Mobile Galayx S7 Edge:
- Download the Android 7 Nougat G935TUVU4BQH7 firmware archive from here.
- note that you need to create an account at SamMobile in order to be allowed to download the file.
- When the download is done you need to extract the contents from the archive.
- you will obtain the G935TUVU4BQH7 BL, CP, AP, HOME_CSC, and CSC Nougat 7.0 firmware update files.
- don't extract these tar.md5 files, as that's how you need to load them in Odin app.
- Download Odin 3.12.3 zip from here. When download is done you have to unzip the files.
- Power off the phone.
- Boot it in Download Mode.
- Launch Odin exe.
- Connect the phone to PC via usb cable.
- wait for ODIN to add the device and then continue to the next step.
- if the phone is not added you need to reinstall the usb drivers.
- Go back to ODIN.
You need to load the firmware update files.
Click BL to load the G935TUVU4BQH7 firmware file with BL in its name.
Click CP and load the G935TUVU4BQH7 firmware file with CP in the name.
Click AP and load G935TUVU4BQH7 firmware file with AP in the name.
Click CSC and load the G935TUVU4BQH7 file with HOME_CSC in its name. Don't load the file with only "CSC" in its name, as that will trigger the complete wiping of all files stored on your smartphone.
- Hit the START button and the Android 7 official update will be applied for your Galaxy S7 Edge phone.
- don't press any buttons until the update is done installing.
- When the update is done you can reboot the phone in normal mode. Unplug the phone from computer when the files are flashed successfully.
Use your default login info in order to regain control over your device once again.
These were the steps you had to follow in order to complete the update.
If installation fails you need to repeat the tutorial once more, and you should get it right the second time. If you need more help tell us in comments.
If the PASS message is shown by ODIN, but your phone enters in a boot loop, or it gets stuck at the boot animation screen for more than 20 minutes, then you should Factory Reset the device.
The Factory Reset process wipes clean system partition, and it should be applied in case you have installed the update over a custom ROM, too. Here's how to Factory Reset your device from Recovery Mode:
- power off the device.
- boot it in Recovery Mode.
- select 'wipe data/ factory reset'.
- confirm process.
- reboot phone in normal mode and you're done with this post.
