CyanogenMod has finally released the Android 6.0 Marshmallow based CM13 Nightlies. It is now available for OnePlus One and few other devices including Nexus 7 (deb & flo), LG G4 (h815), Galaxy Tab Pro 8.4 (mondrianwifi), LG GPad 7.0 (v400 & v410), LG G3 Verizon (vs985) and Moto X 2014 (victara).
So, if you are having OnePlus One and interested in CyanogenMod, this could be the better one to test out. Get all Marshmallow Features and UI right away on your device.
Here are some official Instructions you need to take care before you Flash this build:
If you are on a 12.1 nightly, you can ‘dirty flash’ CM13 (read update like any sane person) as long as you also update your third party addons in the same pass. This means, if you use Xposed, OpenGapps, etc. flash a Marshmallow compatible version of them immediately after your CM13 flash.
If you have taken any unofficial, XDA or self made builds of the CM13 source code, we’d advise you to wipe upon coming to our official nightlies as we cannot ensure upgrade compatibility with third party distributions. Of course, you are welcome to not heed our suggestion, but don’t blame us if something goes sideways.
