Thanks for your help lma. Unfortunately it didn't work for me - I followed it to the letter...and I did gainroot.

This is what worked for me :
1) reflashed (again!) but THIS time I didn't restore the backup.

2) Then powered on the IT, paired the BT keyboard and ..then, restored.

3) Deleted the pairing of the keyboard and...re-paired.

Now, as soon as I power up the keyboard - immediate hook-up. (BT enabled, of course)

Thanks anyways - I now have a better understanding of the commands.
