    Damn, doesnīt work

    This is what I did:
    Copied from N900 to N9:
    obexd to /usr/lib/obex and
    libopenobex.so.2.0.0 to /usr/lib

    Then
    ln -s libopenobex.so.2.0.0 libopenobex.so.2

    Can still pair phone and carkit, but when it tries to transfer contacts it cancels immediately. Nothing transferred at all...

    Thanks again anyway mirakels, your efforts are highly appreciated!

    I'm sorry you got into trouble with the device.
    maybe there is a way to reinstall the obexd package.
    It might be that they setup selinux on the device to guard against overwrites. Guess someone must know about that on the meego forums...

    No worries, wasnīt your fault, appreciate your support on this!
    Did everything on my own risk and canīt even tell what exactly bricked the device. When I tried to investigate this further I noticed that ps | grep obex didnīt give me the usual startup command. So I did a chmod a+x obexd and tried to restart obex manually. But restarting was denied with permission denied (yes I was root). Then I wanted to reboot, but phone just gave me a warning as described before.
    Thus, reinstalling obexd package wasnīt possible and I had to reflash.
    Reflash worked like a charm, so I am again a happy N9 user...Besides the PBAP-issue of course

    I was kinda hoping someone was going to look at update evolution-dataserver to allow more recent versions of obexd etc. to be used.

    The aegis security checks the hashes of the binaries, and compare them to authorized ones. It will prevent you from running your non Nokia signed version, even as root (permission denied), and will prevent the system from running it during boot (bricked device).
    If you don't need too many privileges for obexd, you can try to package your custom version, and install (dpkg) it in devel mode (which may get aegis to register and trust the binary).
    If this needs privileges restricted to Nokia, then you won't be able to change the obexd without using a custom, aegis-free kernel.

    See there for details.

    This was my guess, Aegis being the bad boy here
    But thanks for the details and clarification anyway!
    Unfortunately I have no idea how to package my own version, but at least there is some hope:

    Aha, this is very interesting. Is there any reason that this wouldn't be enabled by default?

    Thank you

    Wrong forum, but do anyone know where the startup options for obexd are specified?

    Can't find it anywhere, and I can't kill the obexd-process, so I can't start it manually with the right options either...

    You can find obex start command in
    /usr/share/dbus-1/services/obexd.service


    (On N900, but should be the same on N9)

    Not sure, but it might be no good idea to edit this file, as it might also brick your device!?
