[Q] Downgrade Bluetooth Software on AT&T S4?

Hello XDA!

So since I got my Galaxy S4 (NC1 build) I have not been able to use the Bluetooth with my car (ACURA TL 2006). Apparently Samsung has upgraded the Bluetooth so far that it is no longer backwards compatible. There are lots of threads about this on ACURA forums, I am sure other cars have the same issue.

Is there anyway that I could :downgrade" the built-in Bluetooth to a lower version so that it works with older devices? Any upgrade doesn't benefit me anyway.

Any help is appreciated!

Did your old phone connect using BT? I'd delete the old profile and start fresh with a new one.

Make sure BT is on and your phone is discoverable. I'd do the easy stuff before trying to downgrade any BT firmware/drivers.

Moved this thread to the Q&A section where it should have been posted originally. The desire to include the [Q] tag should have been your first hint about this

Thank you for your response.

Yes I removed all the profiles from the car (there were like 5 different ones). The car does not see the phone and vice versa. Of course BT is discoverable. There are many threads about this on ACURAZINE forums, both ACURA and Samsung refuse to help. I think its wrong that BT is not backwards compatible.

Thank you for your comment. I have UNFORTUNATELY taken the OTA and my S4 is now on NJ4. No change in Bluetooth thought. My ACURA TL still doesn't see the S4, neither does the S4 see the ACURA TL. (My 10 year old TMobile T610 worth $0.00 easily connects to car bluetooth). I say unfortunately because now I cant even SIM UNLOCK , my previous versions I guess up to MK2 could easily be unlocked with a couple of clicks.
