Does your car kit have Bluetooth 4? if so I guess you need android 4.3+ modem not MF1.
MF3 did not use the same modem but MF2 did with the MF2 name in the system.
You can try to flash like this:
Attach the CSC first then the CP then flash. And if that won't work I guess you'll need to attach the CSC then CP then AP.
The SP700 is OLD
. I've had it for years. It's only Bluetooth 1.1 and just barely supports A2DP (but I have Media disabled on it and I've tested with and without this setting and it makes no difference). It worked great with MF3, but has had problems since ML2 and is just broken now with NE3. Maybe it's just time I replace it outright. I still think this is stupid and wish I could just get MF3 back.
Last night I used 7-Zip and extracted the modem.bin from the NE3 CP Odin file and reflashed that. Baseband now shows NE3 again. I managed to get two Bluetooth calls before it broke again. Yay progress.
Thanks for the help, though.
I also have a Jabra BT620s that uses Bluetooth 1.2 that I will further test with. I'm also debating wiping the phone outright to make sure there isn't a problem, but that is such a pain and Samsung and Google keep making it harder and harder to preserve my data when I do so. So I'm saving that as a last resort. All else fails, I'm going to AT&T to see what they will do about it. We'll see how it goes.
Same results with the BT620s. First call works fine. After that, all call audio is dead. I'm going to backup everything and reflash stock NE3 on it to wipe everything and then test again. It's the only way I can be absolutely sure it's not something I installed.
It appears that flashing back to stock has corrected the bluetooth issue as far as I can tell. Now comes the hard part of slowly reinstalling my apps to see if one of them caused the problem. This is going to take some time. Thanks again for the help, though!
