Default Bluetooth (BT) pairing problems

Hi.. i have an lg e975 and my cousin has the e970 version.. both are having root accesses. .i donno how but yesterday we were unable to pair with each other. .To ma surprise we had the same BT address. . My phone somehow replicated his BT address. . Thats why we're unable to pair with each other. .i tried terminal with this command

rm -rf /data/misc/bluetoothd/*

It returned with rm failed wit. -rf .no such file or directory. .

Then i used without -rf
Still some error : is a directory
Then i used rmdir
Again an error: directory not empty
Then i downloaded this app
bluetooth fix repair from play store,,

It too didn't work..
LASTLY ..i manually deleted the subfolders of
/data/misc/bluetoothd/*
It didn't work cause these subfolders reappear automatically even after deleted..

The 2 phones can pair with other devices but not with each other..

Plzzzz help me out with this.. i dont want to factory reset..
COME ON PEOPLE. .. LOTS OF VIEWS BUT NO REPLIES. .I REALLY NEED YOUR HELP..
