Nokia Lumia 800 1600.2487.8107.12072 Firmware released, fixes volume bug: Install it now

The latest major Firmware update for the Nokia Lumia 800 may have fixed the most important issue; namely the buggy power management, but it unfortunately also introduced an annoying audio volume bug than made playing games in particular a real pain alongside other oddities like a super loud ringer volume the first second when a call arrives. Anyway, Nokia has finally put an end to all of this via a new Firmware update: 1600.2487.8107.12072 which has already started to roll out in some regions and that you can manually apply to your handset by following the instructions below (at your own risk):

- Download the PR 1.2 1600.2487.8107.12072 FW here.
- Download the update from the first link above then download the WPupdate tools from here.
- Unzip the Tools in a folder then copy the firmware to the same folder as the tools.
- Plug in your device, wait until the Zune client starts and then close it.
- Run the the Updater and press S or B (depending on the size of your balls..)
- your phone will then reboot in download mode and update (don’t unplug it or do stupid things with your PC during the whole process..)

Besides the volume bug fix this new 12072 firmware also contains an updated Camera app with auto detection of 50/60Hz and updated camera settings. Unfortunately I can’t see any of those changes… Anyway, there’s also an Improved charger detection in there…happy flashing.

    You’ve got the Version number in the first step wrong ;) I flashed it earlier this day using this method. I can only advise you to create a backup, its always Handy to have one. The whole process with a backup took around 20 minutes.

     Oops you’re right (bout the typo) thanks!

    Yes it’s always advised to to a backup prior to flashing.

    doesn’t work for me the DOS program crashes with Error: no update files :-(

  • http://www.mobiletechworld.com MobileTechWorld

    Did you correctly put the .cab firmware file in the same folder as the WPupdate .exe ?

  • Siddhartha M Yashwanth

     @d55386a678524f6c328bde5c735f88a7:disqus  – Do not unzip the cab file. Just place it in the same folder as the update tool.

    @MobileTechWorld:disqus – It started fine, I chose B (small balls), the backup finished in about 6 minutes and since then, it’s been in the installing mode. The white bar on the phone’s reached it’s full extent. It’s been about 1 hour. What’s going on?

  • http://www.mobiletechworld.com MobileTechWorld

     The update process can take a while..but 1 hour is not normal. If the back-up went fine then you may be able to un-plug your device and try again (or simply restore the backup). I’m not 100% sure though as I have never encountered this issue.

  • Siddhartha M Yashwanth

    OK. That doesn’t scare me at all!
    I think I’ll wait a little longer. Bought this one for 30000 Rupees ($700 approx.). Wouldn’t wanna brick it.

  • Scotty

  • Duncan AY

    If I update my phone with this cab-file, can I still receive the official future updates from Zune from Nokia/Microsoft?

  • http://www.mobiletechworld.com MobileTechWorld

    It gives me an error code: 80188223 with the error message The preinstallation update package (or super package) isn’t signed.

  • Srikanth Vellanki

    Nothing happened…I have downloaded both the files….
    Here are the steps that I followed,
    1. Downloaded “WP7+Update+Cab+Sender” and extracted it into a folder on the desktop
    2. Downloaded “oemupdate.cab.pks_98ed59ede38f0bd78d153d984fcb96e119de2ccd” and put it in “x86″ within “tools” folder
    3. Connected the lumia 800 to the computer…Zune started and then I closed it
    4. Run the “WP7 Update Cab Sender”

    I see the message as “No Update files”

  • Srikanth Vellanki

    Got it….please do not put the file ”
    oemupdate.cab.pks_98ed59ede38f0bd78d153d984fcb96e119de2ccd” in “x86″. It should be in the root folder as “tools” and ”
    WP7 Update Cab Sender”

  • Srikanth Vellanki

    Thank you for the information and will keep you folks posted on the chnages/affects :-)

  • Lgt Mcqueen

    Is that a real phone in the picture?
    I bought a new sim-free lumia 800 and I see a “carrier” info on my “about” page from settings. Is this ok? I start the phone with no sim card and see the same carrier info on the about page. Does this mean my phone is not sim-free?
    Can someone please check this thing on their phone?
    Thank you

    Hello guys… 12072 update has surely resolved the volume bug..  But there is another bug related to volume its still not resolved… I donno whether I am the oly one experiencing this . If there is any one else facing same issue please let me know.. Here is the bug description ” Connect Nokia ear peace or any headsets to your Lumia 800 and play zune music on your lumia 800 . reduce the volume to random volume under 20 or less .. make a call to your lumia 800 and receive the call in your lumia 800.. and check that you cannot adjust the call volume which ranges from 1 to 10. even though volume is reduced to zero, Volume remains loud this is one BUG and the 2nd BUG is after receiving the call cut the cal and once the music resumes playing . it will play with the maximum volume (30) even though volume is set to low (below 20 or so). Kindly share if any one of you are facing this issue,
     Thank you.

    Update works great for me. Just under 3 mins to do a backup and about 4 mins to then apply the updates from 12070 to 12072. I can see the new flicker deduction menu in the camera options. Thanks MobileTechworld!
