by: RJDREYES

Just recently on AT&T Support, announced the new firmware I777UCMD8 – Android 4.1.2 Jelly Bean update for Samsung Galaxy S2 AT&T (SGH-I777). Since, I still have the Smartphone so I give it a try. Recent version came out of the box were Gingerbread then change swiftly to ICS, then for how many months now, the hope for upgrading to Jelly Bean is a dream come true.

I plug the Smartphone on the computer and fire up the Samsung Kies. As the Samsung Kies detect the Smartphone, it will give you a message that there is a new update regarding the firmware. (Note: Check the Baseband version of your phone. Go to Menu > Settings > About Phone. It should be I777UCKH7, I777UCKK6, I777UCLE5, I777UCLK3, or I777UCLL6 before updating. It will be I777UCMD8 after the update.)

But before proceeding on the update, backup everything – files / data / apps / messages / contacts…

So what’s new on the update? Check the screenshots below:
Improved multi-tasking / Customizable widgets /
Improved text input and spell-checking /
New dictionaries for better error correction and word suggestion /
Enhanced web browsing and personalization capability /
Improved email management / Clearer menu formatting /
New technology for better security options /
Google Now with enhanced voice activation /
Adds Browser bar, Drive Mode, ATT Locker, Mobile Hot Spot, Featured Apps widget as preloaded applications / Removes Qik and Mspot applications /
TTY call quality improvement.

(After the firmware updates, it looks like the Samsung Galaxy SII AT&T revive from its old look to a new born Jelly Bean UI and plus, more changes of its settings/features.)

(Note: Tested on Galaxy SII AT&T SGH-I777, it may work also on other Galaxy SII AT&T version, but still I’m not sure about it. Just see for yourself, if you own one.)
