How to Unbrick and Restore YU Yureka to Cyanogen OS 11 Stock Firmware

In case, you’ve bricked Micromax Yureka or if your YU Yureka is stuck in a bootloop then this guide is what you all need. The below stated procedure allows you to flash the official Cyanogen OS 11 factory image on Yureka and help you restore it back to factory condition. The guide is very easy and doesn’t requires using any commands or a toolkit. A simple script will let you automatically flash the stock firmware on Yureka in less than 2 minutes. If you’ve a custom recovery installed or your phone is rooted then that will be replaced to default state as well. The factory images for YU Yureka have now been released by Cyanogen.

WARNING: If you have updated your device to official Cyanogen OS 12, then you CAN NOT DOWNGRADE at all. Current Lollipop is 64-bit OS and KitKat was 32-bit OS. By doing such thing, your device will be hard bricked, this means total dead device without any solution.

Note: For downgrading from CM12 to CM11, follow our new guide:

New – Guide to Downgrade Yureka to CM11 KitKat from Cyanogen OS 12 [Working Method]

Note: This process will WIPE entire data on your phone, except any data stored on the external microSD card. Before proceeding, make sure your phone is charged and you’ve taken a backup of your important data.

9. Disconnect the USB cable, and boot the phone normally by long pressing the Power button.

That’s it! You have restored Yureka to its official Cyanogen OS 11 (4.4) ROM.

      There is a proximity sensor issue with yureka. To overcome this issue follow below steps :

      1) just place a mobile flash light from different mobile on top left corner near speaker
      2) than place unlock button done
