Google had promised that it would be releasing a security fix for all its Nexus devices every month. First month, post the launch of the new Nexus phones, and Google seems to be doing what it had promised. The update to the Nexus phones with security patches for the month of November were released today morning and if you are using a Nexus phone, you would get these updates in the form of an OTA update. And if you do not like waiting to get the OTA update, then Google has made things even easier, where you can simply go ahead and download the factory images for the device that you are using and flash them to your phone.
The versions for the update differ based upon the device that you are using. For the Nexus 5X and Nexus 6P, you would be getting the update via to MDB08M, while you would want to look for MRA58N if you own a Nexus 9, either the WiFi only model or the LTE model. MRA58N is also the version to upgrade your Nexus 5. If you happen to use the 2013 version of the Nexus 7 tablet, then the version you should be looking at is MRA58V. Google has also added the Factory images for the Nexus 6, for which you need the version LMY48X.
From the security bulletin updates which give out the new updates in the latest factory images, one of the issues that Google has ironed out includes patching up a vulnerability where you could enable remote execution of codes via mail, MMS or through web browsing. The issue definitely sounds like something that the media would have picked up on, but it doesn’t look like any potential hacker could expose the vulnerability and just in the nick of time, Google has jumped in and fixed it.
We are not entirely sure when would these updates roll out for the devices in India and it would be better to go ahead and flash the factory images yourself. If you do not know about how to go ahead and flash the factory images, you can follow the guide that Google has written right here.
