OnePlus One updates they are still two complicated births. OxygenOS is already, and I teach to install it, while CyanogenMod 12S was delayed a little more. Waiting seems to come to an end in short and we should start to receive them shortly in the form of OTA, if we have CyanogenMod installed 11S, clear.
As advises Carl Pei, one of the owners of OnePlus, CyanogenMod 12S It has already passed the corresponding certification by Google and in the coming days will begin to serve with system over the air update that we know already.
When exactly? No one knows this and the truth is that OnePlus does well to not give dates this time because his campaign with updates It has been a little disastrous. Simply we can hope to get notice or else they hang the update so it can Flash manually through TWRP.
Which version will be more worthwhile? Difficult decision. On the one hand we have an excellent job done by with this ROM Cyanogen, you have a few options of customization and expect excellent performance. However, it seems that the future of the OnePlus updates will be more focused on OxygenOS.
