Hi Flash2 users,
This guidance require more for your manual operate ability. If you can upgrade to MM from local update, you don't need to try this way. This guidance mainly for the users who have problems during local update and cannot successfully upgrade to Marshmallow. If you are good at flashing ROM, this guidance will be not difficult to follow.
