How To Install Android Lollipop on OnePlus One | Install CM12 on OnePlus One

6

Since Indian one plus one users will not get any upcoming upgrade of Cyanogenmod due to Cyanogenmod’s deal with micromax. We all know that OnePlus is already building Oxygen OS for OnePlus One devices. Rumor was that O2 OS will release on 12th Feb but it will take some more time maybe a month or so. The Oxygen OS seems promising as they said on 12th Feb on their blog (link to post) “OxygenOS will not ship with any bloatware. We’re keeping it clean and streamlined for performance. We value things like battery life and system efficiency, so we’ve remained true to our ROM’s namesake and created a seamless experience that is lightweight and essential”.
Let’s talk about Cyanogenmod which is likely to release the finale version of CM12 which is based on Android 5.0.2/Android Lollipop. You can either wait for Oxygen OS of finale version of Cyanogenmod, but if you want to taste the Lollipop sooner on Bacon you can install CM12 which currently in QA/QE phase. I’m using this since last three days and I didn’t face any issue and it seems very stable till now. There are multiple methods to install this but here I’m going to mention the one which worked for me and I found this very easy to use.
