How To Install Beta Marshmallow Firmware on Galaxy S6 and S6 Edge (OTA Update)

Samsung has just began beta-testing the Android 6.0 Marshmallow firmware for the Samsung Galaxy S6 SM-G920F and its brother, the Galaxy S6 edge SM-G925F. This is the first time that Samsung does something like this, allowing users to test a beta firmware prior official launch.

The Marshmallow firmware for the Galaxy S6 and S6 edge comes with new features, redesigned user interface and improving-battery option called Project Doze which eliminates all services from running in the background when the display is turned off.

Since it is considered beta, the Marshmallow firmware is not available through the usual OTA method. You need to use Samsung’s own Galaxy Care app to download the firmware. Here’s how to do it.

How To Download And Install OTA Beta Marshmallow Update on Galaxy S6 and S6 Edge

Since this is not an open update, there are some tight requirements when it comes to which devices are eligible for the Marshmallow firmware. First of all, your phone’s model number has to be SM-G920F (Galaxy S6) or SM-G925F (Galaxy S6 edge). If your phone doesn’t have this kind of model number then please do not continue as you can damage your phone.

The second thing you should look for is the firmware your phone is currently running on. The beta Marshmallow update is available only for those devices running on the UK BTU firmware (G920FXXU3COI9). If you don’t have this firmware installed, you can flash it using Odin. Do not worry though, you can find everything you need below.

Note: If you are already running on the BTU firmware, you can skip to step 6 on the guide below.

1. Download Odin and extract the zip folder on your computer.

2. Download the BTU firmware for your correct phone model number and extract it to the Odin folder.

3. Click on AP on Odin and select the extracted tar.md5 firmware.

4. Turn the phone off and go into Download Mode (volume down + home + home) and then connect it to your computer via USB cable.

5. On Odin, click the start button. This will flash the BTU firmware on your phone.

6. Once the phone boots up, go to Galaxy Apps and download Galaxy Apps. If you cannot find it, install the app using the provided APK file above.
