is it possibly to install latest os without server

[alittlechild]

If your phone gets old with no more updates can you download and install one with your sd card?

It's not be advisable to do that

Even if it's possible, force installing latest OS on old phones will possibly slows the phone down or intermittent hang as the old processor is not designed to handle latest OS. Just my two cents though.🙂
