How can I upgrade my YU YUREKA’s OS to Lollipop?
YU Yureka comes with a cyanogenmod OS, which is a highly customized version of android. The cyanogenmod 11 available on the current Yureka models is based on android kitkat. The newer version, which is the cyanogenmod 12, based on android lollipop has been released in their new handset, YU Yuphoria. You can download the custom OS file and mount it on to your phone directly or you can wait for the official downloadable version for YU Yureka and the download will automatically be done from your software updater.
