Install Marshmallow 6.0.1 on US Cellular Galaxy S5

It has been more than five months since Google started rolling out its brand new Android 6.0 Marshmallow operating system, but don’t you imagine that everyone is enjoying it. On the contrary, there are still problems at this chapter. There are a few manufacturers which were quick to release the new update and its changes, but there are also others that have been extremely slow to release the Android 6.0.1 Marshmallow update.

I am not at all glad to tell you that Samsung is one of them, but if you are the owner of a Samsung device, then you probably already know that. In February, after weeks of rumors, questions and several days of confusion, Samsung finally pushed out its first Galaxy Marshmallow update and since then, updates keep coming in. Do you want to install Marshmallow 6.0.1 on your US Cellular Galaxy S5?

In such a case, my advice for you is not to skip the preparatory steps. There are some important things that you have to do before you try to install the Android update on your US Cellular Galaxy S5 if you want to succeed and let things go as smooth as possible, so let’s start with the beginning.

Even though this is an official operation, make sure to have your info backed up before you get to the actual flashing, just to be prepared for anything. I also recommend you to clean up your Galaxy S5 getting rid of useless files and data that’s taking up precious space on your device. You’ll be surprised how much junk you’ve accumulated over the past few months and besides that, be sure that Samsung’s Android 6.0.1 Marshmallow update will require some space to install on your process.

Despite of the fact that you can flash the update over rooted firmware, understand that root access will not survive the Android M update. And things are not quite different when it comes to any custom Recovery which is going to be replaced with a stock Recovery image.

You must also have the USB Debugging enabled under the Developer Options section. If you cannot find the Developer Options section under Settings, then you will have to enable it first by going to Settings> About Phone and tapping 7 times on the Build Number section. Return to Settings, scroll down and there you should find the Developer Options. Then, check the battery charge level as it has to be over 60% before starting installation. This will prevent your US Cellular Galaxy S5 smartphone from powering down during the flashing process and will avoid any possible software related issues.

And just to be clear: I am here to guide you, but the steps below are destined for advanced users, I cannot be held responsible in case you brick your Android phone nor in case you lose any data from the process.
