Can we upgrade android software?

Hello,

I have a samsung galaxy s2 which I bough almost 3 years ago and it has very old android version 2 point something. I want to upgrade it to the latest version of android to get all new fun in my device. I don't know what is the process of upgradation?

If any one knows about it, kindly share your experience.

thanks

Follow instructions on this Samsung official page

also follow xda thread for gs2..

the easiest method is still the system settings software update if your device is non rooted..

otherwise from xda website or direct google it..~!

ressurectionremix... this is byfar the best rom for galaxy s2..retaining stock yet highly highly modifiable.
