A little info (for more specific help) before I get started..
-Phone: Samsung Galaxy S2
-Model number: SCH-R760
-Android version: 2.3.6
-OS: Gingerbread.FF18
If I'm missing anything please let me know..

Anyways, I've recently been looking into upgrading the operating system of my phone. However, when I go into my settings and make my phone check for system updates the results always come up negative or I get the Fota error. So I've been looking into doing this manually and it doesn't seem too hard. I'm pretty confident that I can get through it successfully. Although, I do have a few questions.

How safe is it to manually update the OS by myself and what are the chances of rendering my phone inoperable?

Do I have to root my phone in order to do this?

What does this do to my warranty? (I have U.S. Cellular as a carrier, by the way)

Will I still be able to upgrade my phone when the time comes or will it be rejected due to my doing this?

Is there anything else I need to know? Any and all help will be appreciated! Thank you for your time.

You can install a launcher if you want to add style, or if you want to just update android go to settings -> phone info -> actuallisations (updates, sorry if it is a bad spelling; on the top) and check.

I have an S2 as well but updating to anything newer than gingerbread ruined my phone. Stick with 2.3 if you can
