Final Windows Phone 7.5 “Mango” build 7720 leaked

Windows Phone 7 update

The final bits for Windows Phone 7.5 “Mango” leaked online on Friday.

The release to manufacturing (RTM) build 7720 of Windows Phone 7.5 “Mango” has been made available thanks to a workaround for handsets. Microsoft employees have been able to flash their devices to the final bits over the past week and it appears the tools used to do so have leaked. XDA-Developers has posted the tools and instructions for users on NoDo (7390), Mango (7661) and Mango beta refresh (7712). .It’s worth noting that the build does not contain specific OEM customisations or updated device specific firmware so if you flash to the RTM build then you do so at your own risk. For information on how to acquire the tool and instructions please see the XDA-developers thread.

Microsoft is currently testing its final RTM build alongside device OEMs and carriers in preparation for its upcoming rollout over the next two months. Microsoft is expected to unveil a number of new Windows Phone 7.5 “Mango” devices at the IFA consumer electronics show in Berlin on September 1. The final bits for Windows Phone 7.5 “Mango” will be distributed in a similar way to the NoDo update with specific updates for each different device. If you want the latest and greatest then take the risk but if you want a stable device with updated drivers and bug fixes then hold off until Microsoft distributes the official bits in the coming months.

    Installed it on an HTC Arrive. It its much more smoother than 7712. Loving it

  • McAkins Online

    Anyone knows if this works well on HD7?

    • Kane Gao

      Yes. Got it on my HD7 already. Works as great as build 7712. In fact I can’t find anything different betweent the two, except for OS version and the “not for resale” string upon start up. Not worth the effort I’d say.

    • dshe

      There have been minor updates such as Twitter and facebook chat working properly. They were missing from the 7712 build. Also, from the 7720 build, you will probably not need to revert back to nodo to get official OEM specific updates but if you are still on 7712, you will need to re-flash NoDo and update to offical mango for your device. So it is kinda worth it just for that.

  • Jas Chiang

    it’s odd. my Mozart doesn’t have add SSID function after I updated my phone to 7.10.7720.68

    • Shane Nokes

      You won’t see that because that’s something that would be part of a device specific update which is what you get via Zune when they are officially launched.

    • Vincent Haakmat

      I lost the SSID function with my 7712 update also. But I am optimistic that the official version will bring it back

  • Professeur Thibault

    I think that you don’t have to “flash” your device, the leak on XDA allows you to update your smartphone from Mango beta 2 refresh (build 7712) to Mango RTM (build 7720) through Zune!

    • Shane Nokes

      Incorrect. That leak does not utilize Zune for updates. In fact you must close Zune in order to use the leaked files.

      As a further point of information there are things you’re not going to spot with this build that you will notice when the official update pops out on Zune to users.

      The reason being that this build is an OS build, not a device specific build. So all the nice little OEM customizations and the like, you’re not going to get them from installing this.

    • Tom Servo

      Actually it uses the UpdateWP.exe, which Zune is acting as a pretty frontend for.

    • Shane Nokes

      Try opening Zune and running this process and see what happens…just because an application can call another program doesn’t mean they are one and the same.

    Works well on my HTC Trophy 7, Singapore M1 version.

  • Loz Lowe

    Since this is the RTM version, does that mean we won’t have to downgrade to get future updates?

      We cant be sure :-)

    • Loz Lowe

      I’ll wait then. Sounds lazy but I really can’t be bothered to set my phone up from scratch again ;)

    • Zikalify

      Well if its anything like mango we won’t have to downgrade again.

  • Anonymous

    For a second I thought we were going to have much more features in the RTM release than in the Beta2 version.. so far I can’t notice much.. not that Mango is bad.. its good with so many enhancements but I really had my hopes hy on the 500 new features they promised… I’d like to see someone point them out to me because I can’t count more than a hundred from what I’ve seen so far.

    • Gump

      I cant even find 100 if they are lieing about these 500 features I’m going to apple and getting an iphone 5. Dont have time for shinnanigans.

    • dshe

      The 500 features are in the APIs that have been made public for developing applications. The mango build is not final yet and do not expect all 500 features to be in the OS right now. Some features are background workers and live tile updates and background music APIs that applications will use once the mango build becomes officially available and devs update their apps.

    7720 is almost identical to 7712, as wp7 team mentioned.

    However there are some glaring omissions. One is the ‘find on page’ in ie9.

    There are also a few more rough edges which make it looks like it’s a tad rushed in order to provide them to carrier testing and their 2-3 months update process

    Oh and you can get the brand-model update through zune after this one, at least for some models

    • Candid Calum

      It might be best you wait for the official RTM build before you comment on any issues. You cannot install a build an unofficial way (especially when it hasn’t gone through carrier testing), and then state it has issues.

    • Anonymous

      “Code complete” means they won’t add stuff like that. Besides, how does a carrier add ‘find on page’ in ie9 is beyond my understanding.

      It might get some performance boost, but I sincerely doubt it

  • Guest

    So I took the blue pill and went for it. 
    Well, all I could tell you guys that it is better to wait for the REAL Mango. 
    I did a reset, back to the original, update the pre NoDo and then NoDo.  DON’T FORGET TO BACKUP before. 
    I back everything up to skydrive and now trying to get them back.  Ugh!

    • San Ien Jao

      How is this not real mango? Tast real to me?

  • Rendani K Nevhulaudzi

    I rather wait for the stable version, anyway i still love the current build…

  • Anthony Calvert

    I have to say, I am very impressed with Microsoft for their phones.  I am a hugh Google and Apple fan but this OS rocks.  The only thing missing for me is the Game console emulators.:(

  • Gump

    I think I’ll just wait because from what I’ve been hearing isnt to much changing, and I see nothing close to 500 new features, I really believe Microsoft lied about that.

  • Griffin Coulter

    i was just thinking. it seems like microsoft is branching out more so than other companies to get a large variety of oems on board. with fujitsu, zte, nokia etc. i was just thinking do you think they could strike a deal to get HP to make phones? i know, i know they have webos…. but remember what they said about the pc. they said webos would not replace windows 7 because HP sells millions of pcs each year with windows 7 on board. so couldnt they do the same with phones? still make phones with webos but make money off of wp7?

  • Morgan

    I think I will wait. After all the issues I read about from forcing the upgrade the first time coupled with no service provider specific functionality (i.e. visual voicemail), it just doesn’t seem worth the risk.
