version of custom Lollipop update, thanks to the release of

The new CM12.1 ROM follows the recent release of
Cyanogen OS 12S update (click link to see tutorial) for the
flagship handset and it is mandatory to ensure that your
smartphone is already running the Cyanogen OS 12S
update, before you start flashing the CM12.1 ROM on the
handset.

source code via github and also find the necessary Yu
Yureka kernel source code for CM12 ROM here .
The Android 5.1 CyanogenMod 12.1 ROM can be installed
either via TWRP or ClockworkMod (CWM) recovery, using
the step-by-step guide posted below.

Pre-requisites
The instructions given in this guide are meant for

Ensure the phone has at least 80% battery charge
to prevent unexpected device shutdown (due to
battery drain) while installing the ROM.

custom recovery tool, like ClockworkMod (CWM) or
TWRP, as it creates a complete image of the
existing phone setup. In Recovery, choose Backup
and Restore and tap Backup.
Verify correct USB drivers for the phone are
installed on the computer (download Yu Yureka
USB drivers ).
Enable USB Debugging mode via Settings
> Developer Options (if running Android 4.0 or
