AT&T Samsung Galaxy S3 (SGH-I747) 4.1.2 Jelly Bean I747UCDMG2 OTA Update Rolling

The Android 4.1.2 Jelly Bean update on AT&T’s Samsung Galaxy S3 (SGH-I747) has finally arrived. The new firmware version build numbers are I747UCDMG2  and recently rolled out  live via OTA (over the air). This is the ‘Premium Suite’ update that features the long-awaited ‘Multi Window’ support and other 4.1.2 stuff, and well of-course the AT&T’s default bloatwares are still present. This is an update from last December released I747UCDLK3, and it takes around 6 months before this update begins rolling. It’s not too late though, I guess! But an update is still an update.

I747UCDMG2 4.1.2 Jelly Bean:

Software update includes

  • Multi Window: You can open two different apps at the same time into two different windows on the mobile screen.
  • Auto Share Shot with NFC: By setting the camera to “Auto Share Shot” mode, you can quickly share your photos and videos by simply tapping their GALAXY S III with other NFC and S-Beam enabled devices
  • Camera features: Paper artist and best face options.
  • AT&T apps: AT&T services, Drive Mode, AT&T Locker; Family Map, Live TV, and SmartWifi have been loaded.
  • Other enhancements:  Includes calendar, SD Card, and S-Voice enhancements.

AT&T Samsung Galaxy S3 4.1.2 Update UCDMG2
AT&T Samsung Galaxy S3 Android 4.1.2 Jelly Bean Update – 31st of July 2013
  • Android version: 4.1.2
  • Baseband version: I747UCDMG2
  • Build number: JZO54K.I747UCDMG2
  • Kernel version: -3.0.31-1300972
  • Stock I747UCDMG2 Update

This update can be downloaded via OTA update (over the air), which means the release will be in stages, a first come first serve basis which mostly last to a couple of days until all Galaxy S3 devices completely covered this update. To learn more about this update just head-over to AT&T’s support page.

Those who might not root their devices can update quickly,  those who has root might ‘suffer from ‘OTA update failure’ so just make sure you have your device returned  back to stock recovery before performing a live update and/or just look for the OTA update flashable zip file which can be manually installed via  ‘Install Update’ in recovery mode. It’s not available through Kies and we will try to dump the full stock firmware from the server if they release it.  Root still works on this update and no alleged bootloader re-locked patches that blocks users from rooting. AT&T is the friendliest US network to Android community, at-least compared to others though.

Just share to us how’s your first impression about this 4.1.2 Jelly Bean update. Enjoy, and let’s all wait for the upcoming 4.3 updates which I guess may or may not happen too soon.

  1. I did check software and still got nothing! gosh!! how much longer do i wait? heck is there somebody out there can help to this. its been so frustrating waited for nothing! nothing!

  2. I guess your phone is rooted, OTA got you screwed dude! Mine did not received text notification, just checked for an update in Settings–>About Device–>Check Update. it works fine now but some bloatwares are totally useless.

  3. I got the update today. curious tho, I don’t have the Option to customise the Notifications..? nor the new Ticker?just wondering if the i747 doesn’t get this?

  4. Bought the S3 4.1.1 version on Thursday and it worked great. New phone from AT&T. On Friday ( just a day & a half of enjoying the phone), the OTA 4.1.2 update came through immediately wiping the system ui, phone doesn’t ring, added tons of useless bloatware. AT&T tech support was “stumped” & sent me to Samsung tech support equally “stumped” except that the unwanted update could not be undone. If I bought a new phone this should not have happened because you say rooted phones. I’m now thinking AT&T sold me a refurb & not a new phone. A refurb someone rooted maybe?

    1. Nope, AT&T will not do that, they’l not even encourage its subscribers into rooting. Each phone is equipped with hidden security restrictions put in place by the Android operating system for security reasons, mobile phone manufacturers and mobile network operators strictly impose software limitations. Rooting voids your warranty privileges, it might just be a bad luck happens to your phone during the update. Other people also experienced such issues. Yours didn’t even got bricked for it still boots-up while some others suffers into soft-bricks or completely having a dead-phone. AT&T will covers it free of charge, they’ll even replace it with a new one if they finds-out that the problem lies in the circuit board. But still taking your phone to tech-support is totally a waste of time on your side.

  5. Hey, all. I’ve wanted to ask if somebody knows that im able to use this update,because im from Bulgaria (in Europe) and I’ve got Samsung Galaxy S3 SGH-I747 (at&t). I tried to update the phone for the past few weeks, but it keeps saying that there is no update. So my question is if I am able to update it from Bulgaria? Thnaks.

    1. A very interesting question, thank’s!
      As far as I’m concern, you can not eventually update a phone made only for US when your outside US territories through OTA and even Kies. This applies to all who bought from any US network providers and then sent around the world which is basically already unlocked in order to worked with any SIM card.
