How to Force Install Windows Phone 7.8 Update

The Windows Phone 7.8 update which brings in some of the features of WP8 to first generation devices were rolled out yesterday and the process will continue till February. The update will be available for your unlocked phones depending on your location. So if you want to install the update, you need to connect your phone to Zune Software and then check for updates.

But in case Zune is still showing no new updates, you can actually force the update on your Phone. A new tool has been developed by Windows Phone Hacker, called Seven-Eighter which will install the updates directly on the phone.

Disclaimer: Before you update the phone using this method, please note that you will have to update at your own risk WPXBOX will not be responsible for any issues caused because of this update.

This simple little tool to automate the process of downloading and installing the updates to your phone. The application is compatible on Windows and you need to connect the device to PC using the cable and then run the tool. Click on the button Install WP7.8 updates.

Seven eight

This will prompt you to select the languages. Please note you need to select all the languages which are currently available on your phone. Click on OK. Now your phone will reboot an will start installing the update. On the phone you will see a white progress bar indicating the installation of updates.


Once the installation is complete, you will see the phone booting again with the sucess message of installation of updates. Please note if you have not updated the phone for quite some time, you will have to install all the previous updates before you can get WP7.8. So you might have to follow this procedure multiple times.

    how to install the old version 7.5 with nokia lumia 800?

    • Ashish

      You cannot downgrade.

      • Fenix

        u may download Nokia support tool 5 to obtain a rollback version of windows 7.5 tango

    • kumar kund

      can you let me know lumia 710 isn’t support wi-fi internet sharing connection to my laptop & xp3, bcuz other lumia’s have internet sharing option in system application, can u let me know details to solve regarding

  • anshul

    will this work for at&t samsung focus

    • Nirmal

      Not sure on Focus, probably you will need to check with the app developer.

      • siva

        Is this working on lumia 800 for M1variant phone from singapore….official update for this phone is not released…!

  • Chico

    Does it work? Yes, but it’s a little more involved than what is described here.

    First, it requires the installation of the Windows Phone Engineering Flashing Tool. Sure, the SevenEight updater will automatically download them for you, but it is an extra step.

    Second, the tool is archived in a .rar file. If you don’t already have WinRAR installed on your PC, or some other extraction tool which supports the format, that’s an extra step.

    Third, it might actually force Zune to do an update, as well. In my case, after running through the process using the SevenEight updater on my Lumia 900, and updating to Windows Phone 7.8, Zune informed me that I had an update, requiring me to go through the process of updating my phone (this time through Zune) again.

    So, yes, it works, but it’s not exactly as advertised…

    • Nirmal

      SevenEight tool will automatically download everything needed, you do not have to worry about and thats the reason it was not mentioned. Now regarding WinRAR, if you go to finer details, probably I’ll have to write, you will need a Windows OS and a browser and Internet connection before doing this steps :-)
      Zune update happens only if you have not updated previously and it does not happens to all and Zune update is not required if you run the tool multiple times and we have mentioned this in the article.

      • Chico

        @Nirmal, Yes, as I noted, “SevenEight updater will automatically download them for you, but it is an extra step.” I’m just pointing out the extra steps that a noob may have to go through. As for the Zune update, I was already at 7.10.8779.8 (Tango) prior to using the tool. While I realize that there is a 7.10.8783.12 update out there, not sure why it would be necessary to install them sequentially, instead of rolling directly to 7.10.8858.136. But, I’m a Server Admin, NOT a Windows Phone programmer, so I can only assume the need for the sequental update. Although I did not check the versions between what SevenEight applied, and what Zune applied, I’m guessing that’s what happened.

  • maxegger

    thank you very much i really needed the update (i’m in austria and its not even nearly getting out! it was really easy and safe 2 do this ;) thx

    It does not lags on the phone???

    • Nirmal

      I’m not sure on HTC HD7, there is no lag on Lumia phones.

  • Yehey

    The Bluetooth Share App is not installed and also the Camera Applications is not yet installed is there any solutions about this???

    • Ashish

      What do you mean by Not installed ? DO you have the 7.8 update ?

      • http://gmail anelisa

        help me plz…

  • themarioman401

    What language pack should I pick? I live in the US this is my first time

    • Nirmal

      You need to have all the language packs selected on the app which are currently there in your phone. So go to settings in phone and see the languages available.

  • themarioman401

    Oh and it says I have to download something when I click install wp7.8. I downloaded it so what do I do?

    • Nirmal

      Can you please share the exact details on this or a screenshot.

      • KauSam

        Hi Nirmal, can you upload a version for Win32…When I try to install the exe it says it is not a valid Win32 application.

    I’ve updated my 710 using this method but the maximum volume is 19/30. How do I fix it?

  • Perviz

  • Kingdonk1131

    This works beautifully on my HTC Radar …..had to restart it a couple times but it eventually installed all my missing updates ….Thanks!!

  • dkl

    while updating should I select languages listed in Setting/Keyboard or listed in setting/region+languages/Display Languages ?

  • Qandeel

    I can’t update my lumia … It just keep on saying , zunecfg.dll is missing , reinstall the program again.. What should i do? I did everything but still nothing happens

    • HaHeho

      Copy the zunecfg.dll file from your zune installation folder to C:\Program FIles\Zune. So my zune isn’t installed there, it is in C:\Program FIles (x86)\Zune. Perhaps yours is also there.
      Think the updater choosed the wrong zune location because of my update from windows 7 to windows 8 on the laptop.

      • HaHeho

        of course the locations are C:\Program Files…
        sorry for the mistake ;)

  • Domantas
