In this guide, we will let you know how to manually update Lenovo A7000 to Android 6.0 Marshmallow. The Marshmallow update for the device weighs 1.3GB (build number A7000-a_S223_160405_ROW), which you can download and install manually, if you have any issue updating via OTA. However, your Lenovo A7000 should be on build number A7000-a_S153_151127_ROW to apply the update.

First, if you have not received the OTA notification for Android 6.0 update, check it by going to Settings -> About phone -> System updates -> Check for update. If update is available, let it download and install.

If no update is found for some reasons or cannot update via OTA due to network issue, you can download the OTA update file and flash it manually. This is an incremental update, so check for the build number A7000_S153_151127 before applying the update.
