THE SOLUTION TO THE ORIGINAL PROBLEM:

(i tried and it worked: it wiped out the original bluetooth device, so i could restart the process and got the device to pair successfully. --- NOTE: you will see some other items below "Addrs", so try deleting the first one and try re-pairing, it worked for me. If it doesn't work for you, try deleting the second one, etc)
Cheers 😁 !
