Many OnePlus One owners still love their phone and have no need to upgrade outside of having a relatively current version of Android for security and stability. OnePlus has released a handful of new models since the original One release, and updates, although pretty delayed, were still coming to get the official shipping OS up to snuff. Sure, OnePlus and Cyanogen parted ways in 2015 and OnePlus developed OxygenOS as the mainstay OS for all their US phones.
This uneasy but stable situation all changed when Cyanogen announced they were shutting=down in December 2016. I snagged the last build and posted it for download on this post.
- You need to know what you are doing with adb, flashing recovery, etc. If you work this and don’t know what you are doing, you will kill your phone.
- Android Pay and other services that rely on SafetyNet will not work on the unsigned build.
- You’ll get Android 7.1.1 and it is actually quite stable, but it still is a nightly build.
Here are the download links:
