Bluetooth Adapter

[mwyarm]

I have a Bionic where I have installed and uninstalled various personal assistant applications. I found EVA to work the best for me but I get error messages related to the Bluetooth Adapter. The message is something similiar to "the bluetooth adapater is unable to receive the text.." or something similar. As such, the application responds when I press a button but because of the error the phone speakers are off so I cannot hear anything through the bluetooth or otherwise. Sometimes it initially works but then 5 minutes after use the phone drops the bluetooth completely and then everything comes through the phone speakers. The developer of the application thinks it is unique to my phone and my question is it possible for a particular file (Bluetooth Adapter) to become corrupted from various application installs/uninstalls? Since others have not complained, he suggested the problem is unique to my phone. Maybe it is and maybe it is not.

However, since I had planned to root the phone and install Titanium Backup anyway, I thought I could go one step further and reinstall the stock ROM to factory settings to test. I am on the upgraded .893 version.

Questions are:
1) Is it possible to just reinstall a file such as the bluetooth adapter or should I reinstall the whole stock ROM?
2) I have read through many forums and many posts which has 200+ posts and I am not sure which stock ROM is my starting point.
3) Do all ROM's use standard Bluetooth files or are they unique and developed to just support that specific ROM?

Thanks in advance.
