(NEED A ROOTED PHONE)

Use ES File Explorer or another root file explorer app and open as text:

<pre style="background-image: URL(http://2.bp.blogspot.com/_z5ltvMQPaa8/SjJXr_U2YBI/AAAAAAAAAAM/46OqEP32CJ8/s320/codebg.gif); background: #f0f0f0; border: 1px dashed #CCCCCC; color: black; font-family: arial; font-size: 12px; height: auto; line-height: 20px; overflow: auto; padding: 0px; text-align: left; width: 99%;"> /data/misc/bluetoothd/[device bt id]/linkkeys
</pre>
your linkkeys file has to look something like that:

<pre style="background-image: URL(http://2.bp.blogspot.com/_z5ltvMQPaa8/SjJXr_U2YBI/AAAAAAAAAAM/46OqEP32CJ8/s320/codebg.gif); background: #f0f0f0; border: 1px dashed #CCCCCC; color: black; font-family: arial; font-size: 12px; height: auto; line-height: 20px; overflow: auto; padding: 0px; text-align: left; width: 99%;"> 00:1D:BAD:8C:57 FF579860A41CD5A627D9D1596526715C 0 4
00:01:95:08:20:6F 809CC84592E6C1B06AB750170C365812 0 4
6C:23:B9:9B:4A:85 5AF503E766858EA7916D46C16DD31A34 0 4
</pre>

The last entry is my liveview.

Change the last to numbers to 0 4
The 0 is the linkkey type and the 4 the pin lenght.

I just changed the last two numbers from I think
-1 0 to 0 4 so that it looks like the other entries. 

But I don’t know what the 0 stands for.
Have no time for futher research.
