I have a few questions regarding the monthly security updates that are now being delivered. First October then November. I am talking OTA updates not full factory images. 1) Is there a way to install the update with TWRP? 2) Is there a source where I can download a version that can be installed with TWRP or ADB? 3) Do the updates contain any other than security updates, like other enhancements. Is there a change log posted anywhere? 4) Anything else I need to know about these OTAs? EDIT: I've been searching for OTAs and instructions but have come up empty. Tons of stuff on images. Any useful responses to these questions would be appreciated. I did find this: http://forum.xda-developers.com/nexus-6/general/ref-nexus-6-stock-ota-urls-t2906493 It is helpful but doesn't mention MRA58R in relation to U.S. Cellular. 5) Do the OTA security updates break root?
