HTC One M9 getting its Android 5.1 update starting today


Earlier today, owners of the Galaxy S6 and S6 edge got treated to a software update. Now its time for One M9 owners to get some new software.

T-Mobile says that it’s pushing an Android 5.1 update to its HTC One M9 starting today, July 27. The update bumps the One M9 to software version 2.7.531.6, and here’s what the full changelog looks like:

New features


  • Battery improvements

The update is a biggie, weighing in at 833MB, so you may want to seek out a speedy Wi-Fi connection for this one. T-Mo says that the update will be pushed to phones between July 27 and August 20, but if you’d rather not wait — and with Android 5.1, why would you? — you can check for the update manually by going to Settings > About > Software updates > Check now.

Be sure to shout out when your HTC One M9 gets its taste of Android 5.1!

    Finally!!! I checked my phone a few minutes ago and it said it was available. The downside is that now I have to wait until I get to a WiFi connection to download it.

  • Francisco Rivera

    Already have and up until now works great but am a little dissapointed cause did not see the multi user functionality. :(

  • Rick Boone

    Downloaded this morning, haven’t seen too much difference yet.

  • StrangerWithCandy

    Downloaded and attempted install twice, both times it failed. :( I got the Android equivalent of the BSOD and had to reboot. Phooey.

  • Mark

    Yes! I know what I’m doing tonight!

  • Kenneth Warner

    I can’t download it I’m rooted any help howbto get it

    • sikety

      XDA would probably be a much better help then this site.

      • Kenneth Warner

        I got updated =)

    • Evan Lam

      I relocked the bootloader and then installed the stock 1.32.531.33 rom using the RUU that can be found on the XDA forums for the Tmobile M9. After I went through the set up process again, I just searched for the OTA update and it downloaded and installed. It did fail once and make me re-setup the phone and it did take a while the second time, but it did install.

      Just in case, before you do any of this check to make sure that the system is set as read only in TWRP.

      • Kenneth Warner

        Hey man hit a guy up with the RUU site? I wanna make sure I have the correct RUU. Also how do I make sure system is set as read only? Care to make a small tutorial on it?

  • Thatguy

    If your M9 owner you should be furious at HTC for releasing this

    • Mark

      Why? So it’s their next phone, it’s bigger, and it’s not available in the US anyway. I’m not furious that a TV equivalent to the one I paid a couple thousand for 8 years ago is less than $1000 today. I’ll save my fury for the lack of my favorite pastry at the nearest Dunkin’ Donuts.

      • Thatguy

        So you have no problem with a HTC releasing a better phone like 3 month later exclusively too China? Really? You don’t mind the 1080 display when you could have a 1448*2560 (that 4k hommie)? No? What about not having a finger print scanner? The M9 does…. No No your good?…. Your cool with the camera? The M9 plus has a 20MP? Really your good with all dat….
        Ok save your angry for Dunkin Donuts then my firend!

        • sorandkairi

          This has been known for months. What you didn’t know that is that the phone has recently been announced for EU markets. If it were to come to the US then people here may get a little hot under the collar but as of now, its just you.

        • Mark

          No, HTC releasing a better phone doesn’t bother me, whether it’s to China or India or Montana. The 4k screen would be a waste; I don’t use my phone for watching many videos and my eyes don’t need the icons to be any smaller. Yes, maybe the fingerprint scanner would be nice, but it’s not a deal-killer. The M9 and M9+ appear to have very similar camera specs (the M9 has a 20MP camera as well), and if I want to take a pic that warrants anything close to 20MP I’ll use an actual camera anyway (not a big fan of digital zoom as compared to optical). I can get frustrated with battery life in the M9, but that could well be due to the apps I have running and there’s no sign that the M9+ would be any better. So, in short… U mad, bro?

        • Kenneth Warner

          The original m9 has a 20mp too

  • BadBatz

    OK, FWIW (and as an answer to those in the original thread about the update who pooh-poohed my concerns and were oh soooooo happy with their M9s…) here’s the scope of the update:
    Data performance improvements
    Call drop improvements
    Battery life enhancements
    Temperature management optimization
    Camera enhancements
    (other things, like Device Protection, etc.)
    No idea on all other counts but at the same spot (handover from a 4G tower to a 2G/EDGE tower) where my calls would always drop (including this morning) the calls are no longer interrupted after the update, so it is all real. Gosh, my M9 works as well as the M8 now :-)

    • sikety

      Just installed my update. I have also seemed to have issues handing off from towers. On a recent trip from Detroit to Chicago I noticed at one point that it just stopped getting a data signal and I had to restart to get it to pop up. The battery life is my biggest complaint, hopefully this improves that as well.

      On the bright side, during the road trip from Detroit-Chicago I had my wives Iphone 6 in a car mount right next to my M9, the 700Mhz Lte is really no joke, there was a good amount of time where she had 2G and I had full bars LTE.

      • BadBatz

        Yep, pretty much the only reason I updated to M9 were the new bands… Remarkably more places with 4GLTE, mostly in the boondocks (Southern Maryland, Northern New Mexico, etc.) Speed improvements, too…I touch 60/25 in Northern Virginia pretty consistently on M9.
        The battery life sucks big time, update or not… 20 minutes texting with Auto brightness on depleted the battery by 10% (after update.) Hopefully this will be fixed in the future. Also, Google could make the Google Services part use less battery but Google is more and more hell bent on monetizing absolutely everything about the android users which puts more and more stress on the data connection (and battery) so I don’t expect miracles here.

  • sorandkairi

    Damn the update reset my device…

  • Kenneth Warner

    What about the twrp backup that you used?

  • Kenneth Warner

    I did it thanks for the help

  • taxandspend

    Is anyone having an issue since the update where the phone appears to be charging, but doesn’t actually charge, and can even lose charge while on the charger? A reboot temporarily fixes it, but this has happened a couple of times since the update. I’m using the same chargers etc. and never had this issue before.

  • Mark

    I saw it yesterday when using my car charger! There may have been one other strange power-related issue as well but I’m not sure of the timeline so I’ll not describe it unless it happens again.

  • Ryan Lui

    The One M9 is another fantastic phone from HTC. It might be let down slightly by an inconsistent camera and some software niggles, but the One range remains one of the best all-round flagships you can get thanks to the One M9.
