how to upgrade samsung galaxy s2 to jelly bean os
Welcome to Android Forums!
The usual way is to install Samsung's Kies software (available from the Samsung website) on a PC, connect your phone with the USB cable, and use the "Check for updates" function in Kies to download and install available updates.
I hope this helps. If you require further help with this or any other aspect of your phone, please consider registering as a member and joining the friendly community in the Galaxy S2 (International) forum.
