Bluetooth won't turn on.

Hi All,

Please help me with my issue.

My SGG BLuetooth won't turn on. It was working perfectly before.

One day, as I was about to drive, I tried to connect it to my Samsung HM3500 headset (I was already paired with my SGG),

then when I switched on the Bluetooth via the toggle in the Notification, it appears to be turning on with the toggle half-lit.

But after a few seconds, it becomes off.

SO I went to the actual Bluetooth settings by holding the toggle (similar to going to settings, bluetooth)

I switched on bluetooth using the slider, then page says "Turning on Bluetooth..."

Then a few seconds, the slider slides back. And this is driving me crazy. It has been 3 days now.

I followed all the suggestions applicable to SG3, SG2, and others (since no other SGG users seem to experience this),

I turned off phone, pulled out battery, etc..

But it still does not turn on. I want to avoid doing Factory Reset since I have a lot of saved data on my games already and my phone is not rooted (i'm not planning to root it YET).

To my curiosity, I tried pulling a logcat from ADB and switched on bluetooth while logcat is reading.

Here is what I found in it.
