The Samsung Galaxy S II is the latest phone to join the bandwagon of phones officially running Android 4.1 Jelly Bean by receiving the update in several countries around the globe. Apart from a newer version of Android, the new update includes a visual revamp of the User Interface, bringing in TouchWiz 4 (aka Nature UX) that was first released for the Samsung Galaxy S III and a couple of other features as well.
A leaked copy of this firmware had been floating around the internet for quite some time now, credits to SamMobile. The final update is completely the same in terms of visual design, but the UI performance is a lot better with a lot less stutters.

Okay, Now How to Manually Update Samsung Galaxy S2 to Android 4.1.2?
Before we start, please note that:
1. flashing a firmware manually on your phone can be a risky task if you do not follow the steps carefully in their given order.
2. If your phone is currently rooted, it might get stuck in a boot loop after flashing this firmware. This issue can be easily solved by factory resetting the phone through the phone’s recovery mode (Instructions at the end of this tutorial).
However, the stock recovery might also format your internal storage and so installing a custom recovery like ClockWorkMod that does not wipe the internal storage is highly recommended before you continue. You can backup your firmware using it incase anything goes wrong during the flashing process.
3. Flashing this firmware will NOT void your warranty since it’s a signed firmware by Samsung.
Step 1. Download Android 4.1.2 XWLS8 firmware update for Samsung Galaxy S2 from the following link:

Step 3. Restart your Samsung Galaxy S2 in download mode by pressing Home + Power down + Power buttons simultaneously.
Step 4. Choose the firmware that you’ve just downloaded by clicking on the PDA button.
And you’re done!
