How To Install Android Marshmallow 6.0 On Galaxy S2 Plus [Pure AOSP]

Galaxy S2 Plus’s life ended on Android 4.2.2 Jelly Bean. We haven’t seen any update for this device in a long while nor we are expecting Samsung to have a look back. Due to hardware limitations, Galaxy S2 Plus has to stay on Android 4.2.2 Jelly Bean now. The device got higher versions of Android but in the form of custom ROMs. We already have posted the guides to update your Galaxy S2 Plus to Android 4.4 KitKat, Android 5.0 Lollipop. Now that Google has released Android 6.0 Marshmallow, the next firmware that Galaxy S2 Plus users are expecting is the custom Android Marshmallow ROM. The good news is, a pure AOSP custom ROM has already made its way towards the Galaxy S2 Plus I9105 and I9105P.Samsung-Galaxy-S-II-Plus

AOSP Android 6.0 Marshmallow is in the very early stages of development at the moment, but most of the mainstream features are found to be working in this ROM. The working features include Calls, SMS, Mobile Data, Camera, WiFi etc. We will be flashing this ROM on our beloved Galaxy S2 Plus in a while. We only recommend you to go ahead if you’re an Android power user and you have a great idea of custom ROMs. Although this ROM has got most of the features working but we still do not recommend to keep it as a daily driver until we see a complete stable and intact version coming out.
