Ok, spent some time digging today.
The OS package in the rom kitchen is missing the BT PAN service. It's also missing the BT DUN service.
It would seem possible to get one or the other of those *back* into the kitchen, if they were ever in a working kitchen and/or rom.
I didn't download all the kitchens off xda, but if anyone did, we're looking for the OS package with a rgu (ie, registry) file containing either of these keys:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Se rvices\00001116-0000-1000-8000-00805f9b34fb]
@="PAN"
and /or
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Se rvices\00001103-0000-1000-8000-00805F9B34FB]
@="Dialup Networking"
The @= may not be PAN above, but the ServiceID is right - we're looking for one with an actual "xxx.dll"=dword:000000 line following the serviceId string.
If anyone can find such a beast, let me know, as I think that there's the problem with both DUN and PAN, and we should be able to drop the missing stuff into the OS and build it
Edit: A Registry DUMP from a 3.5 machine (or 3.3 for that matter) with working PAN will do. That will identify the PAN dll, and we could possibly just copy it off that machine and roll it in.
Also, if anyone has AKU 2.x installed, can they check the above key in their ROM and let me know what the Dialup Networking says? Bonus points for getting the dll out of \Windows and sending it to me via PM
