How to Update your OnePlus One to Android 6.0 Marshmallow via unofficially CM13


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
phones, but OnePlus One will be one of
the first after Nexuses get it.
However, you don’t even have to wait to
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
itslels)so far on this OnePlus One CM13
– Built in root doesn’t work for me. Had
to flash supersu 2.50 beta.
– 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
pretty functional.
