How to FORCE update Lumia WP7.5 to Windows Phone 7.8 | Tutorial

How to FORCE update Lumia WP7.5 to Windows Phone 7.8 | Tutorial

There was concerns that the Windows Phone 7.8 update was going to be on a slow roll out for the lumia family of devices. A new firmware build of Windows Phone 7.8 ( build 8858 ) has been spotted over at NaviFirm for a number of Lumia devices like the 510, 610, 710, 800, and 900. This can only mean that the official roll out is going to happen very soon, perhaps they want to give us this update for Christmas ? In any case if you want to jump the queue and put WP7.8 on your phone right now , we got a video that will run you through the process. ( WARNING : as always you are on you own if you decide to go down this path , any issues that may arise out of this is all on you and you are likely going to void any warranty in the process )

Please NOTE this is only for Lumia devices .. Samsung / HTC users wont be able to do this.

You Will need the following before you begin

Update Lumia WP7.5 to WP7.8

Video by TheBlackSlaughter via NPU. If you decide to be a daredevil , do let us know how it all went down.

        What’s with the music, I can’t hear what you are saying! FAIL

  • ballanda

    Only available for the non USA 900 variant. Tried flashing it to the US variant last night. Got an error.

  • mark

    There isn’t a firmware variant for AUS versions yet

  • rockhill

    This is not applicable to all countries and carriers for each Lumia device. For example, if you’re on AT&T in the US, your phone is the RM-808, and the only 7.8 update for the 900 is the RM-823. You cannot flash an 808 phone with 823 firmware.

    Some more new things would be nice. FB Live Wallpapers,etc. But Happy at least for now…

    Has anyone managed to update there UK Lumia 900 yet as I cant see a update for the UK lumia 900 in rm-823.

  • Fidt

    Not available to Malaysia as well

  • Gui

    Done. I’m using Lumia 610 and I’m from the Philippines. Thanks! ;)

    • Badeth E

      sir GUI??

      what variant did you choose po? i’m also using lumia 610..

  • Kevin

    I can do it successfully and I’m on EE UK network.

    As this is not an update via Zune, all apps, texts, photo, videos will be erased. Save them down first before you update your phone.

    Thanks for the instructions!

    • Kevin

      And my phone is Lumia 900

  • Josh

    Worked on my lumia 900 but i had to use the second most recent update.

    there was also a bug which meant i had to restart my phone because the date and time wouldn’t set.

    Other than that it all went perfectly well!

  • SteveTh3Pirate

    Worked a treat, just match your product code to the ROM your updating to. BINGO WP7.8 is on your handset :)

  • Prabhu

    i am getting this error “UNKNOWN PRODUCT” and a question mark in red.help me what to do my phone is lumia 800.

  • nsbimia

    any1 tried to find phone from slovenia? i checked all releases but i didnt find it.
    any suggestion?

  • Roger

    Excellent! Updated my Lumia 710 in New Zealand – had to use an Argentinian variant, but all good after setting language/location

  • nsbimia

    may i take any other phone or it has to be from my country?

  • BillAbong

    Nokia_Care_Suite_5.0_2012.5.5.5 Will not install

  • Billy

    Why the hell that background string music..distracting your weak voice..

  • medeis

    easiest way to force update is to use packet analyzer (like wireshark). Update contains 4 phases, first (1) is http request (green in wireshark by default), next (2) encrypted data (grey) -> (3) http request (green / here internet should be disconnected) -> (4) http request (green) – this last request should be avoided to allow zune show available / forced updates.

      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…

    For everybody who’s complaining about the background music and the weak voice – read the damn description!

  • john

  • jesus

    Jesus you just wasted about an hour of my time, your voice is so fucking weird and that music…

    Whatever you do when you finish kindergarten do not go into any thing that involves talking to people.

    This shit does not work.
