I just found a new trick to avoid other people steal your file.
This way make your bluetooth cant find other device in range.
Apps required
1. Hacked phone
2. X-plore
3. Jbaktaskman
This is the step
1. Open jbaktaskman. Hit menu, tools, processes and find btmanserver.exe
Terminate this processes.
2. Enable open4all patch
3. Go to xplore c://private/100012a5/DBS_100069CC_btregistry
Just delete this file.
4. Make a new file with xplore and it should be "DBS_100069CC_btregistry.txt"
5. Rename it with name "DBS_100069CC_btregistry" and set the attribute to read only.
Now, if you trying to send anyfile via bluetooth, the pop up will appear.
"sending failed"
To make your bluetooth active, just remove read only attribute and delete "DBS_100069CC_btregistry"
