I would like to upgrade my KitKat 4.4.4 to either Lollipop or Marshmallow, whichever would be best at this point. I am not really familiar with the Android way of doing things, so I’m stumped as to what it is I need to do. I’ve found several upgrade downloads, but I don’t know which file to use first, as the files and their extensions are different than what I’m accustomed to dealing with. I really like the Android operating system, and would like to upgrade if at all possible. I feel a little dense, as I can usually seek and find the answers I’m looking for, but would really appreciate any help anyone could give. Thank you in advance for any assistance.
