Just received an OTA update and I pressed the install without hesitate. But it is only another small security update for Android 5.1.1. From LMY48M to LMY48T.
Baded on the post on xda developers forum, Android 6, Marshmallow update is available to Nexus 7 2013 Wifi version. It will be MRA58K.
This post said Nexus 9 or some Nexus 6 version need to upgrade from LMY48M to LMY48T first, then it can be upgraded to MRA58K. They are two parts upgrade.
So, can I say the MRA58K will be soon on my Nexus 7?
