How to install watchOS 2

Today, Apple unveiled watchOS 2, and it’s a major upgrade to the initial version of watchOS. When you think about it, it’s pretty amazing that we’re getting such improved functionality less than 2 months from the debut of Apple Watch.

As it usually does on WWDC keynote day, Apple has made its OS updates available for download immediately. If you’re an Apple developer member, a privilege that now extends across all platforms for only $99, you can download and install watchOS 2 today.

The installation is fairly arduous and time-consuming, but it can be done with relative ease if you have the patience. But I definitely don’t recommend that anyone but a developer does this, because there is no way to downgrade back to watchOS 1.01.

In this post and video tutorial, we’ll show you what you need to prepare to install watchOS 2, and how to install watchOS 2 on your Apple Watch.

Download the files

Note: to download the beta’s you will need to be an Apple Developer

Step 1: Unpair your iPhone and Apple Watch, if you don’t you’ll need to reset your Apple Watch later and repair it. I personally prefer to reset my Apple Watch to defaults anyway. It’s nice to start with a fresh install for a beta.

Step 2: Download and install the iOS 9 beta on your iPhone from the Apple Developer portal

Register your iPhone

Note: If your iOS device is already registered as a developer device, you should be able to skip this section of the tutorial. Also, the UDID requested is for your iPhone, not your Apple Watch.

Step 1: Download and install the iOS 9 SDK (Xcode 7 beta) from the Apple Developer portal

Step 2: Connect your iPhone to your Mac

Step 3: Launch Xcode 7 beta

Step 4: Click Window → Organizer

Step 5: Copy the 40-character UDID in the identifier field

Step 6: Sign in to Certificates, Identifiers & Profiles using your developer-registered Apple ID

Step 7: Click the + sign to begin registration

Step 8: Name your device and paste in the UDID from Step 4

Step 9: Click continue to confirm and complete registration

Install watchOS beta 2 on your Apple Watch

Step 1: Pair your Apple Watch

Step 2: Charge your Apple Watch do that it has at least 50% charge and keep it connected to its inductive charger throughout the installation process

Step 3: Connect your iPhone to Wi-Fi

Step 4: Place your iPhone next to your Apple Watch

Step 5: Download the watchOS 2 beta Configuration from the Apple Developer portal directly to your iPhone

Step 6: Launch the profile, tap Apple Watch as install location and reboot when asked

Step 7: Launch the Apple Watch app on iPhone

Step 8: Tap My Watch → General → Software Update

Step 9: If requested, enter your passcode

Step 10: Wait for the Apple logo to appear and watch the progress bar fill in completely

Step 11: Your Apple Watch will reboot once the update is completed

That’s all there is to it. You should now be able to enjoy watchOS 2 and all of its perks on your Apple Watch.

What do you think? Was it easy? Check back, as we’ll have much more coverage of watchOS 2 over the next few days and weeks.

    Immediately disappointed when I read this is only possible for app developers currently. Looks as if I’ll have to wait until Fall… That is, unless you can get labeled as a developer, without actually developing anything. Thoughts?

    • CA

      Find someone willing to register your UDID and you’re good to go.

      • socrates

        Have you been lucky enough to convince someone of that?

      • CA

        I highly suggest finding someone you can trust, if you can’t you can always register using one of the well known sites and pay anywhere from 5-15 dollars USD. Just be smart and read any reviews before paying if you go that route.

      • edouardbirman

        hey guys, if you want to try iOS 9 and get your UDID registered,contact me at edouard94300@hotmail.fr

      • CA

        NO!

      • socrates

        Thanks. Much appreciated.

        Is Apple known to take disciplinary action against users who do this?

      • eXoguti097

        I don’t think so, but I wouldn’t trust someone saying that in the comments. I’d find a popular site that is known to do it for about $8, I’ve done it before they’re perfectly legit. Google iMZDL and look for the register UDID link

      • socrates

        Thanks, worked like a charm.

    • Lucus Bendzsa

      I just did this with no activation.

      • MRTEE

        How did you get pass the certificate sign in eith your developer sign in if you not a developer ? I have got my idid registered but not sure if i would be able to install the watch os without issue.

      • Lucus Bendzsa

        I downloaded the certificate directly to my phone, installed it, and updated the watch.

      • seanysean

        and how did you do that?

      • socrates

        I have the same inquiry as MRTEE.

  • Szabolcs Toth

    So if my iPhone’s UDID is registered with a developer account, and i am running iOS 9 on my iPhone, i should be able to complete this process right? No need for adittional registration of the watch roght? Please confirm this, if you have experience, I’m a little unclear about this, even after reading the article. Thanks.

    • Ronaldo Villanueva

      You need to register the watch’s UDID also. You get that from Xcode.

      • Szabolcs Toth

        Ok, thanks for the info, that’s what i was afraid of, seems like this will remain the privilege of true developers atm, because that’s not as easy as going to a website and just reg your UDID like for the iPhone, shame, i would have loved to try out the watch OS beta, but just for the sake of betas 99$ a year is bit steep 😛

      • MRTEE

        so even if one get the watch udid registered with a developer account, can one still be able to install the watch os 2?i have registered my udid from a reliable source.

      • Ronaldo Villanueva

        Yes, once the iPhone is ruining iOS 9 and you have registered the watch’s UDID, you can go ahead and install watchOS 2.

      • Maega

        It doesn’t look like you need the Watch’s UDID registered.
        Since my developer program licence expired I decided to just go for the online UDID registration instead and save around $95. Long story short, watchOS 2 is installing to my Apple Watch now with the mobileconfig Profile installed to it and the iPhone on iOS 9.

        It seems only the iPhone has to be registered. I guess we’ll see for sure after it’s installed but even according to iDB only the iPhone needs to have a registered UDID..

      • MRTEE

        so if i go to a website to get my watch udid registered the bit where jef said (Sign in to Certificates, Identifiers & Profiles using your developer-registered Apple ID).does it mean I’m still out of luck since I’m not the real developer?or i can use my public sign beta id to sign in?

      • MRTEE

  • Dominic LoFranco

    I have reached a terrible dilemma, Do I upgrade to iOS 9 and loose my jailbreak, or do I keep my jailbreak and forget about iOS 9?? I am a developer, and I am on iPad mini, iOS 8.1.1(I think).

    • Rupinder

      If you are a developer, I’d say lose the jailbreak. Ultimately up to you though!

  • Merman123

    Jeff tapping the iPhone screen expecting it to turn on lol… Apple Watch owner probs…

  • MaRz Franco

    This did take a while to update, more then 2 hrs. Also, anyone notice syncing photos is not working. I can’t seem to get the new watch face photo.

    • Kr00

      API’s used for iCloud services between devices usually don’t work with beta software until the GM is released. I’m guessing this is one of them.

  • edouardbirman

    • Kr00

      Why, when holding the option key whilst choosing “check for updates” in iTunes still works. Anyone can download iOS 9 from iMZDL.

  • Falco

    and how do i reinstall watchOS 1.0.1 when i’m on watchOS 2?

    • Sven De Mey

      Good question I would like to see answered as well 🙂

    • Adam Baligian

      Same here. I’m wondering if removing the mobileconfig profile will do it.

      • Falco

        I’ll try it as soon as i updated my watch to watchOS 2 and let you know if this works.

      • Falco

        Removing the profile won’t do the trick. Somebody figured out how already?

      • stanley

        hi falco ill teach you how to do it 😀

      • Falco

        Teach me master

      • stanley

        have you installed ios 9?

      • Falco

        It’s not possible to install watchOS 2 without having an iPhone with iOS 9 on it…so dumb question :S

      • Falco

        i already have installed watchOS 2, that’s not the problem, the problem is, how to downgrade to 1.0.1 again my friend 🙂

      • Jordan Stevens

        The disclaimer says you can’t downgrade once you’ve updated the watch. The reason I’m leery about trying it until the beta improves some.

      • sscapecchi

        how to remove profile??

  • Chang in Charge

    Is there a native Notes and Reminders app now?

  • Nathan Peterson

    After I’ve updated to 9.0 and my Apple Watch am I still able to go back to 8.3 and enjoy the features of the watch. I just want an updated watch; not phone.

  • Mike

    Be aware once you update the apple watch OS to version 2 you cannot downgrade and once the watch is running V. 2 your iPhone has to have iOS 9 to be able to pair.

    • MRTEE

      Can you still downgrade the iphone after pairing and still enjoys the features of the apple watch

      • Mike

        Good question, I haven’t tried that yet. Report back if you find out.

      • Mike

        Thinking this over, if you downgrade your iPhone isnt going to remember the pairing I don’t think

  • edouardbirman

    hey guys, if you want to try iOS 9 and get your UDID registered,contact me at edouard94300@hotmail.fr

  • benjitek

    It looks like if you have iOS9 on your iPhone, you don’t need to have your Watch’s UDID registered — if you want to install watchOS2 without updating your iPhone to iOS9, then you need to register your Watch’s UDID. Regardless, you need OS9 to pair…

  • edouardbirman

    hey guys, if you want to try iOS 9 and get your UDID registered,contact me at edouard94300@hotmail.fr

  • I’ve gone through all the steps in the video (though I had to reset my watch after updating to iOS 9, and I am STILL getting “Profile Installation Failed The device is locked.” I registered my UDID (checked it twice). Any idea what the problem could be???

    • James

      Yeah, you need to unlock your watch.. Wake it up and type the pin in.

    • Alexander Goldfarb

      Lol I had the same issue, took me 15 minutes to figure this out 🙂

  • Alexander Goldfarb

    Does anybody have any luck with the downgrade of WatchOS (with or/without downgrading iOS to 8.3)?

  • Simon Oh

    How do I downgrade to watchOS 1.0.1? Or is that not possible…

    • JayDee917

      Why do you want to downgrade, if you don’t mind me asking? Is it not stable? I’m thinking about upgrading to the beta…

      • Simon Oh

        It’s kind of buggy, but not to the state where you can’t use it, and the Watch app on the iPhone is also kind of buggy. Otherwise, it’s fine.

  • Dante Arellano

    I was called to the apple watch watcho” mexican inglish dialect for watch now is watchOS very funny

  • Dante Arellano

    Dame ya still playing with the shitty half by one inch screen?

  • zebonaut
