H710 won't reset after holdg all buttons. can't get pairing mode
If you can't reset your device- try this, which I just fiddled with and
got mine to work (I had same problem). On headset, close boom, hold
center button (and it turns pink). then, while keeping center button
depressed, open boom- light remains pink. Then look on phone, and hit
Add new device-- and bingo, it should be recognized now!! You'll be
asked if u want to pair w/ Motorola-- and led through the
process--follow those steps. The passcode, as mentioned by others on these posts, is 0000 (four zeros).
I had tried similar earlier, but the trick was to keep the button
depressed, and then open the boom. I can't quite remember if I kept
button depresed until I also pressed Add new device on phone or just
until after opening the boom and the light stayed on ... Sorry I can't
be exact; I was too excited. Hope this helps you get yours working!
