You can now update your OnePlus One
to Android 6.0 Marshmallow via CM13
or an AOSP ROM. CM13 is yet to
officially make it to Android devices,
which will probably start with Nexus

the first after Nexuses get it.

even get CM13 officially. Folks over at
OnePlus forums have successfully cooked
up an unofficial CM13 ROM for OnePlus
Below's a list of bugs discovered (by

– Titanium backup crashes
– Camera will launch, but once your try
to take picture, it says cannot connect to
– Location tile is very iffy. Seems to work
sometimes, and not others
– CM file manager does not work
The ROM has issues with Camera so
wouldn't recommend you to use it as
your daily driver yet, but other that it's
