Hi. Need a bit help from you all. Am having a ASUS Nexus 7, bought just couple of days ago, is already running on 4.1 jelly bean. But I heard that Google has launched an update for the same again. Now as my tab becomes slow or I can say it lags sometimes. I doubt that it happens because of huge Data stored on the device (about 30GB) but still for my satisfaction I would like to install the Android 4.1.1 firmware on my Nexus 7. I tried searching it with OTA but it wasn’t available there. So could any of you please let me know how to update firmware on Android Nexus tab manually? Thanks in advance.
