Helen, Aug 14, 2015 : Hi all Here's an OxygenOS 1.0.2 update for your OnePlus One containing patches for the recent "Stagefright" security exploit. "Stagefright" is basically a vulnerability in the multimedia stack that can be exploited via MMS which could compromise your phone. If you are currently using OxygenOS, I would highly recommend upgrading to this version for your own safety. Again, before flashing, please backup all your data just to be safe. https://s3.amazonaws.com/oxygenos.oneplus.net/ONE_12_A.01_150813.zip https://s3.amazonaws.com/oxygenos.oneplus.net/ONE_12_A.01_150813.zip.md5 If you are already on OxygenOS, this update does not require a reset. For detailed installation guide, you can find it here https://forums.oneplus.net/threads/oxygenos-is-here-installation-guide.289398/ ***** UPDATE 8/18 ***** Google has released a couple more patches for Stagefright which we will be incorporating over the next few days. We are anticipating another rollout before the end of next week. Stay tuned.
