    Desktop Software v7.1.0.41 (Bundle 42) has no problem connecting to BB 8830 and 9320 but identifies 9720 as "unknown device". The PIN is actually recognized but Backup and Restore buttons are grayed out:

    Is there any solution to this?

    Windows OS: XP 32-bit
    BB Desktop Software v7.1.0.41 (Bundle 42)
    Installer: 710_b042_multilanguage.exe
    Download link:

    BB 9720 is the last BBOS device and was released in August of 2013, a few months after the release of Q10 and Z10. It seems that by then all DM updates had been discontinued and BB 9720 was left out unsupported. At this point it is just speculation but an image file of 9720 missing in Device folder and no mention of 9720 in DeviceCharacteristics.xml (in the same folder) seem to confirm this:

    Do you have installed the last version of the OS? Maybe @thurask can help you...

    The OS on the phone is Bundle 3008, which is higher than the official CB OS:

    7.1.0.1121 (Bundle 3008):

    https://i.postimg.cc/3Jrs1X03/DM-9720-h.png

    I don't have an OS installed on PC, I would need to find that bundle somewhere first. The version available on CB is:

    7.1.0.1121 (Bundle 2994):

    https://forums.crackberry.com/blackberry-9720-f408/

    If someone confirms that device OS Bundle 2994 works with Desktop Software v7.1.0.41 (Bundle 42) then I might just downgrade device OS to 7.1.0.1121 (Bundle 2994).

    Then again, I don't have any BB OS at all installed on PC and BB 8830 and 9320 connect to DM without problems.
