  1. my wifi is not turning on will the wifi work when i upgrade to 8.0 via the process you gave

    1. Hi Shefin. The problem you’re facing could be solved by performing a factory reset. Here’s what I suggest you should do:
      1) Take a backup of all your important data, including that on the internal storage. Everything will be erased.
      2) Upgrade your phone to Android Oreo using this method.
      3) After successfully upgrading, boot your phone into the OS and check if WiFi works now.
      4) If it still doesn’t work, then perform a factory data reset via the settings menu.
