Android Lollipop Update Guide: Custom Release for Google Nexus 5 Brings Stagefright Fix

By

Google Nexus 2015 is among the lucky devices to run a version of Android 5.1.1 Lollipop via CyanogenMod 12.1 custom ROM created by developer community XDA. The Lollipop-based custom ROM brings with it a solution to the notorious Stagefright threat.

Released recently to Motorola Moto E (1st Gen), CM12.1 primarily carries the patch to fix Stagefright, a security vulnerability attack usually operating through MMS like Google Hangout and Whatsapp. The threat attacks through a video message sent to a device. When the device's user clicks the message, it could steal or destroy some data without the user knowing it. This problem was first noticed months ago after subsequent releases of 5.1 Lollipop.

To go on with the download, LG-manufactured Nexus 5 owners should take into consideration the following reminders.
