AOSP Android 6.0 Marshmallow custom ROM has made its way to the original Galaxy Grand GT-I9082 and GT-I9082L. If you’re looking for a way  to flash this custom ROM in order to give your Galaxy Grand a look and feel of the all new Android 6.0 Marshmallow, you may find this post pretty useful. We are going to learn a step-by-step set of instructions to install Android 6.0 Marshmallow AOSP custom ROM on our beloved Galaxy Grand GT-I9082 and I9082L in the succeeding guide. Before we install Marshmallow on Galaxy Grand, we will have a recap of this device.

Galaxy Grand, Samsung’s mid-ranger popped up for the first time back in the year 2013. Samsung flaunted this phone with a 5-inch 480p display. Galaxy Grand caught an 8 MP shooter at its back and 2 MP on the front. A Dual-core CPU clocked at 1.2 GHz was fixed inside alongside a RAM of 1 GB. Galaxy Grand ran on Android 4.1.2 Jelly Bean and was upgraded to Android 4.2.2 Jelly Bean and that’s where its official software support died. Samsung didn’t look back at this device and since then, the only new life this device has been getting is by means of custom ROMs. Earlier we posted a method to update the Galaxy Grand to Android 5.0 Lollipop using a custom ROM as well. Now that Marshmallow custom ROM is available, we will flash this ROM on Galaxy Grand and enjoy the latest and greatest version of Google’s Android OS. Let’s learn a little bit about this AOSP Android 6.0 Marshmallow in order to be able to install it now.

Current version of Android 6.0 Marshmallow AOSP ROM is in the alpha stages. The ROM is expected to be buggy and unstable. The mainstream features like Calls, SMS, Mobile Data, Camera and sensors are found to be working. Some features like FM Radio, Google Play Movies are not working for now. You may flash this ROM on your device just to enjoy the Marshmallow firmware, but it may not be kept as a daily driver. Also make sure that you know how these custom ROMs work and how to handle them. We recommend newbies to be very careful while flashing this ROM. Let’s have a look on the working stuff and the known issues.

What’s working in this AOSP Android 6.0 Marshmallow for Galaxy Grand?

• RIL (Calls, SMS, Mobile Data)
• Wi-Fi/Bluetooth
• Sensors (Accelerometer, Compass, Light, Proximity, etc.)
• Camera
• Video (playback & recording)
• Audio (playback & recording)
• GPS
• Everything else not listed under “known issues”

What’s not working?

• SELinux is in permissive mode
