Band 12 support arrives for Samsung Galaxy Avant in latest software update

galaxy avant

Starting today, T-Mobile is beginning the rollout of a software update which finally brings Band 12 support to the Samsung Galaxy Avant. Although it’s not an update to Android 5.0 Lollipop, it will enable those with the budget smartphone to access the carrier’s stronger, low-band network.

Software version G386TUVU1AOD7 was made available to download over-the-air from today, May 11 and – as far as we know – it’s not a staggered release. If you have software versions G386TUVU1ANK3 or G386TUVU1ANHA, at least 50% battery and a Wi-Fi connection, you should be able to download it right away. If you haven’t received notification of its availability just yet, go in to your settings menu and check for updates manually. If that doesn’t work, you can try using the Samsung Kies PC/Mac software and install the update via USB connection.

Interestingly, the size of the update is different depending which version of Android you’re currently running on your Galaxy Avant. If you have G386TUVU1ANHA, your update will be 122.67MB while those running G386TUVU1ANK3 only have 104.92MB to download and install.

Read more about the software update over at T-Mobile’s support page for the device.

Thanks for the tip, Patrick.

    Any time, Cam.

    • Nick

      Do you know if you can root it after the update? I know sometimes updates break root support

      • patrick mclaughlin

        im not sure. i hate rooting phones so i don’t know anything about that

  • Verizonthunder

    Hey Cam any news if T-Mobile will carry the blackberry passport?

    • zacamandapio

      that would be something.
      I’ll buy that in a heartbeat.

      • Verizonthunder

        I agree I saw they updated the processor from a snapdragon 800 to 801 I want in white.

  • Nick

    Does anybody know if I will be able to root again after this update?

    • Mike

      idk for sure, but instructions are already online for how to unlock band 12 on the avant, and it was really easy to do. so if that is all the update truly had, you could just go that route and keep your root as is

      • Nick

        True. Kies isn’t finding an update anyways

  • Logan S

    I got an Avant from eBay back in March as a backup phone, and it was already B12 capable. It just had to be turned on via Service Menu. I verified that it was getting Band 12 here in Washington DC Metro. Nice to see coverage in underground parking garages!

    So, even without the update, all you have to do is enable Band 12. Google “Avant enable Band 12” and the Howard Forums link will show you how.

    • Logan S

      And use LTE Discovery app to show Band 12 connection.

    • Yup, Way back when, there was an article mentioning that the Galaxy Avant is band 12 capable. However, it was not enabled at the time, and it could be enabled manually. But for those who aren’t tech users, this update is good for them.

    • Bradley Karas

      Yep found it in that 700 mhz map from the forum. You can actually go into service mode in any Android phone but you can’t turn it on and off like on the avant

    I want the the Blackberry Passport! I don’t know why, but I’m starting to think Blackberry OS 10.x is better than android and iOS. Blackberry is the future.

    • Verizonthunder

      Guess what Amazon app store is pre-loaded on new bb os also you can download Google play store with 90 percent of the apps working too

    • JLV90

      I’m thinking Windows is the future with their announcements of porting Android and iOS apps to Windows that is huge, with apps like Candy Crush already using the porting process as an example. Also Contiuum where you can use your phone on a second screen as if it was a real computer while still having your phone work independently showing it’s own apps, messages, email etc.

    And I want a pony tail!

  • Jay J. Blanco

    How nice. Sell more LTE devices that’s band 2 and 12 capable tmobile

  • iMotoXperiaGalaxy

    The hell is this phone?


    • JLV90

      A low to mid range smart phone. It’s decent maybe close to an S3 in terms of performance, lacks screen quality and camera quality though.

  • Mario Gallegos

    Is this update also for the MetroPCS version galaxy avant

    • Patrick McLaughlin

      Yes it is

      • Mario Gallegos

        Thats weird I have not received it yet

      • Robert and Kimberly Coplien

        how do i update from the metro version of this phone to tmobile firmware?no root just unlocked to work on tmobile.

  • sushimane

    hopefully tmobile does a massive update for the sony xperia z3 android 5.0 or 5.1 and unlocking the Band 12. Moving to Massachusetts they currently have 6mhz of 700 but after the tv relocated to a different frequency.

  • Grandy

    When will the Avant get Android 5.0?

  • Adam

    Does this update also add WiFi calling VoLTE hand off?

    • Mr. Literacy

      Does the article make any mention of it? Hmmm, you just answered your own question, or did you not read the post?

      • Adam

        I’m looking for information beyond the article.

        • Steve Curay

          Will Golden State win the NBA title? See what I did there?

  • Grandy

    Wow. I’m surprised my question didn’t get the same treatment as Adam’s. Not only is answering a question with a question lacking relevance rude, but it discourages an exchange of ideas and building of knowledge.
