Google just recently announced that Android 6.0.1 Marshmallow, which includes more than 200 new emoji and a few UI tweaks for tablets, would soon be starting to roll out to Nexus current devices. It looks like things have already started moving along quite nicely, as Google has just posted Android 6.0.1 factory images on the Google Developers website.
6.0.1 factory images are now available for the Nexus 6P, Nexus 5X, Nexus 6, Nexus 5, Nexus 9 (Wi-Fi and LTE), 2013 Nexus 7 (Wi-Fi and LTE) and the Nexus Player. The new software arrives as build MMB29K for the majority of the devices listed, except for the Nexus 6P and Player, which now reside at build MMB29M.
Just remember that flashing a new ROM will restore your device back to factory settings, so make sure to have your info backed up before you get to flashing. If you’ve tinkered around your device in the past and feel comfortable doing so without any extra help, you can find the new factory images at the source link attached below. If you’re new to this or need a little guidance on manually installing Marshmallow on your device, be sure to read our guide.
