Quite a few people are having trouble with their Bluetooth profiles in OS .191. Some issues are the inability to modify the profiles, inability to delete profiles, and losing Bluetooth functions. This is either due to an incompatibility between the old O.S. and new O.S. or corruption of the Bluetooth profiles during the upgrade process. Before you throw the phone against the wall, follow these instructions.
The easiest thing to do is not run into this problem. To avoid it, delete your Bluetooth profiles from your current O.S. BEFORE upgrading to .191 or possibly any 5.0 O.S. release. Make sure that you create a data backup that does not have Bluetooth profiles in it. This will ensure that .191 is installed without any profiles set-up, and then NEVER restore data using a backup that includes Bluetooth profiles; only restore the data from your BT "clean" backup.
If it's too late, you've already installed the shiny new 5.0 O.S., and now you're having Bluetooth problems, don't fret! You're going to need to have some spare time on hand, but it can (most likely) be fixed.
Using the upgrade and downgrade instructions found in this forum, downgrade your O.S. to the previous version where you had working Bluetooth, and make sure your data is restored so your phone is just the way it was before you upgraded. NOW, delete ALL your Bluetooth profiles and reboot your phone. After the reboot verify that your Bluetooth list is free from any profiles. If they are still there, delete and reboot again. Repeat until they are gone for sure. I know, sounds funny, but I had mine reappear once after rebooting.
Now your phone should be setup the way you want it except without any Bluetooth profiles. At this point you need to do a data backup. Make sure you make some sort of a mental (or otherwise) note that this backup is completely free of Bluetooth profiles.
Now follow the upgrade instructions to upgrade back to .191. For good measure (and to make sure your apps transfer), make sure you select the option to backup your apps and data during the upgrade. Then upgrade the OS and restore the data either using the backup that was done during the install or the backup you did just before that was clean of Bluetooth profiles. DO NOT EVER restore data with any other backup you have done in the past. Restoring with a previous backup will reinstall your old Bluetooth profiles and you will have to start this process all over!
Now you should have the new O.S. installed and all your data and apps should be installed the way things were before. Check your Bluetooth list and make sure there are no profiles. If there are profiles then you did something wrong and somehow ended up restoring them from the previous O.S. Sorry, you will have to start over if that's the case! however, if you followed the directions correctly (or I made them easy enough to follow), you should have an empty Bluetooth list. If it's empty you are GOOD TO GO!
Now, re-create your Bluetooth profiles within the new O.S. and pair up your devices. Everything should work as well or better than it did before!
