How to Update the Samsung Galaxy S5 to Android 6.0.1 Marshmallow?

Samsung urges us to prepare the following important notes to consider before performing the software update.  I have also added some useful insights why you should follow this procedure to keep your  phone in safe.

Recharge the phone’s battery – You should make sure your device is fully recharged before performing the software update. Do not also remove the battery during the software update is in progress. A power failure may cause damaged to your device that might result to what we called “soft-bricks”.  If this happened on your device, it may just stuck on Samsung logo or welcome screen and can’t reboot normally.

Backup important data – You should back-up your important files, including contacts, emails, messages, photos, videos, apps and other stuff. Like I said while during software update process is interrupted there is a possibility that your data stored from your device internal SD card may lose or deleted when a sudden unexpected failure happened and it forces you to perform a factory data reset which basically wipes your phone’s memory.

Ensure that your Galaxy S5 should still running in an official or factory firmware and hasn’t been rooted nor modified – Your device should not be modified or rooted, there are some certain circumstances that a modified and rooted Galaxy S5 SM-G900T may not accept any official software update anymore or it can accept an update but it might harm your device once the update has made. Learn about the new Samsung KNOX security suite. Most known error that says ‘firmware upgrade encountered an issue, please select recovery mode in Kies and try again‘ or “Your device has been modified Software update are not available” you should try to avoid that from happening.

How to Perform an Update via Over-The-Air (OTA)?

This is usually how the carrier branded or locked Samsung Galaxy S5, performs a software update.  This method is Firmware Update through over the air or called as OTA update, which most often  a notification message will directly send out to you from your network provider or Samsung and notifies you that there is a new update available for download.  If you did not receive any notification messages you can manually check for the update instead.  Doing this you may only tap on your Galaxy S5 SM-G900T Settings >About Device > Software Update.
  • From the Home screen, touch the Settings icon.
  • Touch About device.
  • Touch Software update.

It will automatically tell you that a new update is available or your software is up to date when there is none yet. You can simply tap install now when you want to perform an update or install later.

How to Update the Galaxy S5 Thru Kies / Smart Switch?

The second method is a firmware update through Samsung Kies / Smart Switch for PC. You may head over to your  local Samsung support page from where you can download Samsung Kies from there, and install it in your Windows or Mac computer. Choose the new Kies 3 which supports the Galaxy S5 SM-G900T and other Samsung devices running with Android 6.0.1 Marshmallow OS .  Once you installed Kies / Smart Switch, all you need is connect your Samsung Galaxy S5 into your PC using the USB data cable, then simply run and follow Kies or Smart Switch on-screen’s software update instruction.
