How to upgrade Lenovo A7000 plus Android Lollipop to Android 6.0 Marsmallow
At last after the news that Lenovo a7000 plus will release an update for Android 6.0 or Marsmallow this upcoming month of April. This  was already leaked by unknown Chinese Hacker in other Social Community Website and Forum.

   
      This Marsmallow ROM was originally from Lenovo K3 Note which also compatible in Lenovo a7000 plus by using the "modem patch" that are always used in Lenovo K3 Note Rom. Recently, I already published Lenovo K3 Note on how to upgrade to Marsmallow using stock recovery, but this only 50% chances to update successfully.
      Thankfully, with the help of our Developer Mr. Cuoc092  find ways and things possible to install the Rom using Custom recovery (TWRP) with 99% success rate.
      According to him this is stable version and haven't found any issue at the moment.
