    so im going to try and reinstall my OS tomorrow but im trying to figure out how its done. Namely, where do i find the site to downgrade the latest OS version? or a previous version? i had good luck with .732 but so far the current version is lagging up my device really bad....think it might be a bad upgrade or too many app downloads/uninstalls LOL....

    Don't use Desktop Manager
    Here is one way to do it:

    1. Download the 975 exe (or whatever OS you want to load to your phone) to your pc. IF you want, try an OS6 leak
    2. Delete all other OS installations from your pc.
    3. Install the 975 to your pc.
    4. plug your phone into your pc with a usb cable.
    5. If you want to shrink the OS (remove some of the extra files) download BB Hybrid Tools from here:BBHybrids Tool (Public Version) - Downloads - BBHybrids Forums
    IF NOT, jump to step 7
    6. If you are shrinking, double click bb hybrid tools exe and open the window and check anything you DO NOT want to install. Click SHRINK MY OS when finished.
    7. If you ARE NOT using a shrinking method, jump from Step 4 right to here and look for vendor.xml by going to c:/programfiles/commonfiles/researchinmotion/apploader/vendor.xml
    delete vendor file if you see it
    8. then stay in that same folder and double click the LOADER.exe file and your OS will start to install.

    During the process, the loader will backup your data and apps, wipe your device and load the new OS and put everything back.

    Hope this helps. Process takes about 20 mins.

    What she said, she's the queen of leaked, hybrid and other OS installs!

    +1 Jaydee, I've been using app loader as the way to upgrade and downgrade for a while now and there really isn't a better way!

    ++1 for apploader, it's the best way to upgrade your OS.

    Thanks, I ended up finding that site and rolling back to .732. Much more normal battery life.
