Install AOSP Android 6.0 Marshmallow On Google Nexus 7 2012

Google Nexus 7 2012 is out of the Android Marshmallow league. Marshmallow requires an upgraded hardware to run on, which is not possible on the Google Nexus 7 2012. To serve the Nexus 7 2012 with Android 6.0 Marshmallow sweetness, XDA member dmitrygr has put forward a custom AOSP Android 6.0 Marshmallow ROM. The ROM works with both WiFi and 3G variants of the Nexus 7 2012. Initial builds of this ROM are found to have a working Camera, Bluetooth, GPS, WiFi, NFC and Sensors. In case you’ve been living in a bit of disappointment because of Google’s decision of not updating this device to Android Marshmallow, you may want to try this out and give your device a makeover of Android 6.0 Marshmallow.Nexus7

This ROM is still in development stages and it is not guaranteed to work without any errors. This build of ROM is intended for Android power users who are good with custom ROMs, and who know how to handle the device in case something goes wrong.
