T-Mobile HTC One Receiving Update to Build 1.27.531.11 – Still Android 4.1.2

htc one2

The HTC One on T-Mobile will start receiving an update as early as this morning that will improve stability, LTE connectivity, and reception, plus enhance a couple of processor issues. The update is to build 1.27.531.11, and is 247MB in size. Unfortunately, it does not appear to be the 4.2 update that has been reaching international variants of the device over the last week or so. Once you have updated, you’ll still be running Android 4.1.2. 

To update, you can wait for the update to pop-up on your device, or sideload it through HTC’s website.

    Still no OTA or HTC website update. Has anyone received this update? I don’t understand why they would say its rolling out if no one is getting it. T-Mobile is terrible, actually all us carriers are terrible with Software Updates. Other countries have already received the 4.2.2 update and we are getting a minor update? this is crap.

    I meet all the prereqs for this, but nothing yet.

  • DronePro

    Devs are patiently waiting… now where’s the damn link… Tmo?

  • col3rsc

    Don’t see the file on HTC’s website.

    • PhoenixPath

      Not there yet. No update on my handset yet either. Patience, young padawan. 🙂

      (I haven’t seen any reports of this actually landing on anyone’s device up to this point, so it may not be quite “live” yet)

        Earlier this morning it had the .8 update listed with install instructions (do it OTA) on support.htc.com, now that section is completely gone. Hopefully that means they are about to refresh the page with the update.

        I’ve just downloaded this update today.

  • emcdonald75

    Dang!!! My HTC One comes in the mail today and I sincerely hoped that the update was the 4.2.2. update. Well, I guess I will have to wait just like the people who have had the phone from the beginning for the update that really matters…4.2.2.

  • This is pretty typical of T-Mobile. As far as the big 4 US carriers go, T-Mobile is the absolute worst in terms of updating carrier-branded handsets. And yes, I’ve been a Verizon customer and am currently an AT&T customer.

      Just one thing that makes your comment invalid………..Verizon Galaxy Nexus!

      • I hope you’re kidding me. The Verizon Galaxy Nexus received every single update that Google gave to Verizon for testing. Yes, the VZW Galaxy Nexus never got 4.1.2, 4.2, or 4.2.1, but that’s not Verizon’s fault. Google themselves never sent the updates over to Verizon for testing in the first place. I owned a Verizon Galaxy Nexus for over a year and kept it bone stock. If you’re aware of update history on that phone, there is a guy well known in the XDA community named “El Madhatter”. He has a Verizon testing phone and his device consistently gets the latest Galaxy Nexus updates weeks (sometimes over a month) before general rollout. I work with him every time he gets an update to pull the update URLs for the community. His phone never received any testing updates from 4.1.1 to 4.1.2, 4.2, or 4.2.1. Even the testing builds went straight from 4.1.1 to 4.2.2. This tells me that Google never even bothered releasing the others to Verizon for testing. And honestly, who could blame them? 4.2 and 4.2.1 were full of bugs. 4.2.2 was the first truly stable build so it makes sense that they waited to release it to Verizon for testing.

        T-Mobile is absolutely NOTORIOUS for telling OEMs “thanks for making this update available for the phone, but we’re not going to allow this on our variant.” I can point you to countless examples of this. Here are two choice examples:

        1. Nokia made an update to Windows Phone 7.8 available for the Nokia Lumia 710. T-Mobile passed on the update electing to keep their variant on Windows Phone 7.5. There was even a press release stating such.

        2. The LG Optimus 2X was marketed in the US as the T-Mobile G2X and ran stock Android. LG updated the Optimus 2X to Ice Cream Sandwich, but T-Mobile passed on the update for their variant, leaving it on Gingerbread.

        Lots of carriers engaged in practices like this years ago, but T-Mobile is really the only one who holds steadfast to this in the name of “it doesn’t improve customer experience.” With AT&T, Verizon, and Sprint, if an OEM releases an update to them for testing, you can rest assured that the device WILL get it at some point. Yeah, it may take a while, but it’ll get there eventually. That is not a given with T-Mobile. T-Mobile is the smallest of the four carriers and they can’t devote the QA resources to updates that the other guys can.

        • Steve

          Ok so obviously you think that Verizon didn’t tell Google not to worry about the minor updates. Leave it to you, Google is the bad guy right, and Verizon is the worlds fastest at updates. I’ve had Verizon, and they were not the greatest. Plainly put, if the update is straight from the OEM, Verizon has to have it done their way, and they are by far the worst at it. They change everything from the devices name with its “DROID” branding, to its software. So far, Sprint runs circles around the competition with its release date times, then AT&T, T-Mobile, and lastly Verizon.

          • Weber

            Don’t listen to this guy. He’s made the same, tired argument about T-Mo time and time again. VZW sucks with updates. Why would Google put the updates on the site, but not give them to Verizon? That’s the dumbest thing I’ve ever heard. And his two examples, one of which is a Windows Phone, are pretty much moot.

          • It’s possible that Verizon told them to leave behind the minor updates. If they did, then clearly Google found those terms acceptable. In terms of Verizon “having to have it done thier way” or “rebranding stuff to DROID”, we’re getting away from the original point. My only point is, if an OEM makes an update available for a Verizon device, Verizon will play the testing game with it and push it out. T-Mobile will not always play the testing game with an update and will instead elect to pass on it altogether. My point stops there.

        • Robert Boluyt

          Verizon’s completely inept handling of the Galaxy Nexus is the biggest reason I’m no longer on Verizon. Due to Verizon’s painfully slow ‘testing’ process, there wasn’t any point in releasing the minor builds that the GSM Nexii got a week after they were posted. The 4.0.4 OTA was 6 months late, the 4.1.1 OTA was a few months late, and the 4.2.2 OTA was nearly a year late. Complete and utter stupidity on Verizon’s part. People bought the GNex on Verizon hoping to avoid Verizon’s usual non-existent update process and instead got reemed even worse than before.

          Buy a puppy, dude. No one should know that much about phone versions. Nevermind the puppy, buy a blow up doll.

  • John

    Couldn’t get a picture of a T-Mobile HTC One eh?

    • no no no

      umm.. lol it is .., tmobile’s htc one is not marked duh

  • AndreKP2124

    Wake me up when the HTC ONE gets Android 4.3 ZzZzZzZzZzZzZzZz……..

    • PhoenixPath

      You’re joking, right? It’s not out yet…and it’s a minor update at that in preparation for 5.0 (probably coming in November).

    • Robert Boluyt

      Its an HTC, 4.2.2 is the only OS update we’re going to get. You want 4.3 or 5.x, you’ll be rooting or buying a new phone. :/

  • Jarred Sutherland

    “Enhance a couple of processor issues” just sounds funny. Almost like they are adding more bugs and saying “LOOK! FEATURES!” .. but then again, this is HTC.

  • PyroHoltz

    Remind me how long 4.2 has been out…this is fairly unacceptable for HTC to push an update when a similar version of the phone has already seen 4.2.

    • PhoenixPath


      HTC is not pushing this update. HTC has already pushed 4.2.2.

      • Justin W

        Not to the U.S. unlocked version. That’s coming straight from HTC, and I haven’t gotten the update yet.

        • PhoenixPath

          Not surprised. I just checked and they don’t have the Global OTA available for download yet. I suppose they want to finish the roll-out before posting it. Doesn’t make much sense (ugh..) as the OTA is available on pretty much every dev site known to man, but eh…whaddaya gonna do, right?
