Recently, Cherry Mobile released an official update for Flare S3 Octa (Lollipop) via OTA. Unfortunately, many users experienced bootloop and whitescreen while updating their device via OTA. Approximately only 10 % success rate and still has bug and problem like in camera, gaming and etc.

This tutorial help you to update CM flare S3 Octa to Lollipop Version (android 5.1) manually via Stock Recovery. Many users encountered error updating their device via OTA. I suggest before  making an update you need to full unroot and remove all the apps that has root access like xposed, greenify and etc.
 Some incidence, even full unroot they can't update due to unknown reasons. This only 80% chances to update successfully. Here's a new tutorial for easy to update it via stock recovery. But I'm not sure if could work to all of you.

2. Go to recovery mode. Just Reboot your phone Hold volume Up and Power simultaneously.
