If you are looking to update your T-Mobile Galaxy S7 manually, then the operation listed here is what you need, but let me ask you: are you sure that this is what you want?
Let me remind you that it is essential to get familiar with the Android 6.0.1 update, to find out what it has to offer and so on in order to be sure that this is what you are looking for. In fact, checking the update’s performance before you take the plunge with a new operating system is the best thing to do in all cases.
However, if you know for sure that this is what you need (after all, you are the owner of a brand new T-Mobile Galaxy S7 device), here I am to help you.
To successfully complete the steps below, you need a computer/laptop, so remember that for Odin to open on your computer you will need to block any Samsung official updating tools from running on your computer. Another essential step is to enable USB Debugging for your device from the Developer Options section on your T-Mobile Galaxy S7. If you cannot find it, enable it first by going to Settings> About Phone and tap 7 times on the Build Number section. Then, return to Settings, find the Developer Options and enable USB Debugging.
When it comes to your files, most of them are probably backed up in the cloud already, but don’t take that for granted. Head into your Settings to make sure that your most important files are backed up properly and if you need additional help, then use this tutorial: Use kantjer’s Tasker Profiles to Back Up your Android device. Yes, I know that factory resetting the S7 smartphone will not delete any data from internal storage, but I tend to take everything into consideration including the possibility of losing your data due to an error.
I also know that you don’t want your Galaxy S7 phone dying during the Android Marshmallow installation process so make sure you properly charge the battery at the right time. By that, I mean that you must plug in the charger before starting to apply the steps from below or else, you might have an unpleasant surprise.
Even more, don’t blame me for losing the root access or for seeing your custom Recovery replaced with a stock Recovery image. This is what it normally happens during such an operation, so stop here if you don’t agree. And it’s better to double check than to mess things up, so don’t hesitate to use this post only for the T-Mobile version of the Samsung Galaxy S7 devices with model number SM – G930T. Check the version of your device under Settings> About Phone and avoid getting yourself into trouble.
As for the fact that this is official update operation, be sure that you won’t lose your phone’s warranty if you choose to use the guidelines from below.
