    Hello,

    Can you or anyone tell me where you got the Firmware downloads and csc ? Im trying to downgrade my Samsung Ativ Odyssey and this method looks like it would work with the correct firmware to flash.

    Thanks
    Jerhomey
    This roms is ONLY for Samsung Ativ S I8750, it's not for Odyssey. You will brick your device if you flash with this files

    Anyone tried this with the official 8.1 and firmware? doesn't seem to work any more. I think the firmware has changed the download mode somehow and it mo longer is picked up and able to be flashed by the binary downloader. Just never sees phone and phone does not show up as a com device any more when in download mode.

    Thank your for the post.

    I followed the instructions and I was able to revert my unstable WP8.1.1 back to WP 8 GDR3.

    Thanks, it worked fine, and after nearly a day of updating, updating, updating, reinstalling apps, and typing in passwords, my ATIV is where it ought to be. It remembers its name. It remembers the ringtone and message tone I selected. And talking over Bluetooth seems to work consistently well in my car.

    BUT: It still doesn't notice there are many gigabytes of pictures on the phone. And it didn't find all the music on it - and in some cases the album art was wrong or missing, and perfectly tagged albums showed up as "Unknown Artist." Guess you can't have it all.

    Help, I installed the update yesterday and now my phone is in reboot loop and I can't revert back! I've done everything as the first guy instructed, but my Ativ S is only recognized as 'WP8 USB Manager' in Device Manager, and so isn't reconized in SMB. I installed the driver from the yandex link and it said it's correctly installed, but it still isn't working. In device manager properties of my phone, it sais no driver is assigned. I've tried repairing, removing etc. of the driver.. nothing works. I have Windows 10.

    Strange, if its a software or firmware issue Samsung will definitely be able to fixed it. Even if there is hardware problem they should be able to fix as well. Is your phone still under warranty?

    I had a similar problem back in May when I updated the WP 8.1 developer preview from WP 8 GDR 3. It when into continuous boot loop every one minute.

    As my warranty was still valid and took it back to Samsung Service centre and they flashed it back to default WP 8 GDR1 (which was the official Hong Kong version in May 2014).

    Thank you very much! :) Done! Just a little tip for Windows 8.1 Update 1 64 bit:
    You need to disable the Win8 signed driver enforcement before installing the Samsung Windows Phone IO USB driver. Thanks again!

    Has anybody tried this revert process with ATIV S model SGH-T889M? That's the model I have, and noticed there is a file on original poster's file share called "SGH-T889M VLCMK2_r_signed.wp8" for GDR3.

    This works for the SGH-T899M. Check the thread below for what you need to download, and other helpful information:

    Hey guys I get a "Partition information is not equal." error.

    The driver and everything installed fine.
    OS Version: 8.10.14219.341
    Firmware revision number: 2424.13.5.1

    It gives me the option to "download all binary?" YES and NO.
    I've opted for NO so far, is YES safe?

    EDIT: I also wanted to revert to GDR2 as my firmware is very very old and I want to catch as many official updates as possible.

    EDIT2: This is probably due to the little update that Windows Insider installs when you first register it. In THEORY I don't think it's a big problem, as Microsoft always hinted their "partition-stitching" technique, and loading a smaller, old WP8 GDR2 on my stitched, larger system partition should not be a problem? After all, the current OS does not take up all the partition either because it's just 8.1 Update 1, not 10. Unless they fill it with dummy files.

    EDIT3: I yolo'd it and flashed GDR3 despite the partition size error. Worked perfectly!

    I think I might be screwed... I have installed W10M 10536 on my Ativ S and it is actually working pretty well. But now I want to revert back to WP8.1 and I just can't get the phone to be recognized by my computers. Both a Surface Pro 3 and a desktop PC running 8.1 Pro x64. I tried installing the driver with signature check disabled, the driver installs fine. But when I switch to download mode and plug my phone in the SMD download (v3.47/3.5/3.54) just stops responding...

    I even tried running a virtual install of Windows 7 32-bit in Virtualbox and it installs the driver fine, but when I plug in the phone it still can't find a driver. Guess I'm stuck on W10M.

    /!\ You must use SMD v3.54 in order to downgrade your phone from W10M to WP8.1.1 or you are going to brick it.
    About SMD binary downloader crashing, I never encountered this problem... :S
    Does it stop responding indefinitely? It's maybe a conflict with another program or an antivirus.
