How to force the Windows Phone 7.8 update on most phones

Windows Phone 7.8 has finally started rolling out for several devices, but there are still many more to go. Unless you’re an owner of a Nokia phone you probably have not received the update yet. There is a way that has worked for some people that allows you to force the 7.8 update to arrive. This is the official update, not some hacky ROM or unofficial build. All it takes is a little patience, a computer than can have WiFi turned off, a data cable, and your phone. Let’s begin.

  1. Turn off WiFi and data on your phone
  2. Connect to Zune
  3. In Zune, go to Settings and check for an update
  4. As soon as you click “Update” disconnect from the internet.
  5. After Zune says it can’t check for an update reconnect to the internet
  6. There should be an update ready this time
  7. Follow along with the wizard to complete the update

Make sure to try this a few times if it doesn’t work right away. Timing is key, so it may take several tries before you get it. This won’t work for all Windows Phone devices, so if it doesn’t work after several tries you probably won’t be able to get it. Patience is the only answer for that. Let us know if this works for you!

  • Awesome! thank you! I am trying asap.

  • JD

    Has anyone tried this for HTC Radar ? I tried but does not work… May be I am not patient enough.

  • I’ve heard it doesn’t work with many HTC phones.

  • Didnt work on my 900 after 3 tries. Ill just wait until it appears normally. thank for posting anyways.

  • garuav

    i have htc radar and i tried this trick but does not work for me…..

  • tried with htc radar, didn’t work

  • Jimbo

    Worked on an LG E900. The trick was making sure your connection was hardwired, not Wi-Fi, so you can get offline faster. This post isn’t quite accurate. Here’s a tip from a comment on the WMPower User post, this is what worked for me, but it took a bunch of tries: “Basically if you get the “Can’t check for updates right now message,” you pulled your Internet connection too soon. If you get the phone is up to date message, then you waited too long. Here’s what I had to do: count 1 Mississippi and pull it to see which message I got. (got can’t update) Then 2 Mississippi and pull and so on until I got “the phone is up to date” message (at 4 Mississippi or 4 seconds). At this point I knew the sweet spot was between 3 and 4 seconds. I went through and pulled it when I got to 4 Miss and it worked.”

    It took me almost 200 times to get 3 update chances.. patience is the best policy in this case..

  • dick

    I am on lumia 710.. or may be because of wifi, it took so much effort…

  • darknite

    Im trying with HTC Radar…could install upto 7.10.8783.12. Would inform you all …if I get 8858 update. By the way…trying with ethernet cable, pulling off.

  • darknite

    Yippeee…. got it folks….in HTC Radar.

    By the way the updates werent cumulative as mentioned.

    I had to do it like the below.

    1st time (3 updates) 8107 -> i dont remember the number -> 8773

    2nd time (single update) 8773 -> 8779 (the update worked -> but had to reset the date time in the phone manually even though the settings was to update date and time)

    3rd time (single update) 8779 -> 8783

    4th time (single update) 8783 -> 8858 (WP 7.8)

    I tried with connecting connecting and disconnecting cable ethernet cable (and count 3 or sometimes 4)
    Cant connect : means you are too quick
    you phone is up to date : you are too slow….

    Im happy…. :) hope the happiness spreads to all of you


  • Bulgarche

    It works, just be patient! If you receive “not able to check for updates”, you pulled out too quickly, it depends on the speed of your internet… I’m with HTC Mpzart, from Bulgaria

  • JD

    Congrats ! Since you got it working, can you please document your steps and share the link for HTC Radar ? Thanks much….

  • Billy

    Yes it’s all about timing. When clicking update,count about 4 seconds before disconnecting from the internet; that’s how it worked for me. Nokia Lumia 900, USA

  • Billy

    I’m not sure, but maybe the connection speed plays a role on how long you should give it before disconnecting from the internet. As darknite said “Cant connect: means you are too quick / your phone is up to date : means you are too slow”, that’s a good tip.

  • Allan Francisco Jesalva

    Hi, I’m from the Philippines and I have a locked Lumia 800.When I plugged in to Zune, it initially said my phone’s OS is updated. I tried what I read somewhere that you have to time when the message “Your phone is updated” shows up. You have to pull the cable 2 seconds before the message shows, and you will get the message that there’s an update available. I am now updating on the last update, build 8858 or WP 7.8

  • Raj

    AWESOME!!! It worked with my HTC RADAR… long wait came to an end :)

    1st update time (single update) 8773 -> 8779

    2nd time (single update) 8779 -> 8783

    3rd time (single update) 8783 -> 8858 (WP 7.8)

    You have to repeat the procedure mentioned for each single update.

    tip: Give ZUNE enough time to connect to the net but not enough to validate the official release.

  • Mircea Alexandru

  • ACI

  • Bill

  • Rajesh

  • GetPaid Everyday

    Worked on mine, Nokia Lumia 900 is udating now. Took me at least 10 tries at disconnecting from the internet at various intervals. With highspeed T3 connection, I disconnected after 2-3 seconds and the update started.

  • GetPaid Everyday

    I have an HTC Motzart, HTC HD7, and Nokia Lumia 900 and it worked on all of them.

  • thanks. maybe i will give it another go.

  • Erika

    It works :) Lumia 800 O2 UK contract. Disconnect just after 3 seconds, just before 4 :) Took about 8 attempts, possibly more.

  • SiKo

    I can confirm that this worked on a HTC 7 Trophy, unlocked.
    Had to find my timing, and update several smaller updates first till 7.8 appeared.
    So far, it works like a charm.

  • 9JA Boy for Life!!

    Yep..Did work for me. U will have to do the same process (3/4x) for each update. Also u will need a stopwatch to determine how your internet connects to the updates and study the times when u disconnect..(esp in Nigeria.) Anyway, Thanks for the tip Bro!

  • IWJW

    I was sceptical, BUT… IT WORKS!! be patient and you have to wait the right amount of time!

  • les

    i got the update deal but i hit close before i could plug it in phone so what do i do

  • Ajeng

    it worked on my Radar!!! i had been reading so many articles but only your words led me to 7.8 :p it took long time but i’m so happy ritenow. THANKYOU SOSOSO MUUUCH :D

  • Ajeng

    just do it all over again. keep trying till 8858. it took 4-5x for my Radar. and it worked :)

  • Mathew

    I have updated mu Lumia 610 from Chennai using your idea. wonderful method, need to test by varying the time before disconnection. It worked with a count of 15 for me. thanks.

  • darknite

    you are welcome!

  • Succeed to get the update, but failed in the final step of updating (restarting your phone) :(

    Here is how i managed to get the update:

    1.Connect your WP device to the PC and make sure your Wi-Fi and cellular data was turned off.

    2.Open up Zune

    3.Get ready with your stopwatch (This thing really help me out!)

    4.Navigate to Phone > Settings > Update

    5.Count the seconds using the stopwatch since you pressed the ‘update’ tab until the ‘Your phone is up to date’ shows up. REMEMBER THE SECONDS COUNTED.

    6.Select other tab in the phone settings except the ‘update’ tab (ie: Name Your Phone)

    7.Repeat the step 3 until 5 again. Make sure this time, the seconds was same with before’s result. If it is not same, repeat it until its same. So make sure you got a stabile connection. (I’ve got 8 seconds)

    8.OK, now Select other tab in the phone settings except the ‘update’ tab again. (I’ve not disconnected the phone with the PC.)

    9.Now, select the ‘Update’ tab again, then disconnect the internet with minus 1 until 2 seconds from the counted time before. Then, prays alot! :)

    10. Wait…. and ta-da!

    Sorry if i got so many grammar vault. Im Indonesian and using Telkomsel. (and im just 12 years old!)

  • Ok, Now i know why im failed on the final process. Just dont let yor computer goes hibernate or turning off, so use your computer to do small task such as typing ;)
