The problem I have is that I've already entered 4 wrong codes. Three of those are from a DCT4 calculator I used more than 2 years ago. I think I used +1, +5, and +7 at the time, I don't quite remember. The fourth one is from entering a code provided by AT&T itself. I got the phone from the *old* AT&T, before it became Cingular. IMEI REMOVED This is what AT&T provided #PW+928632557042117+1# I'm wondering if I could have made the mistake of forgetting to entering the final "1". Would I get a wrong code error even though the number of digits in the code is one short?
The code provided to you by AT&T should be the correct one, but the phone only allows 5 total tries ever, then you must unlock the phone with a USB cable. It is possible that either you're not remembering correctly, or someone else has also tried to unlock the phone. Also - Don't post your IMEI in the public forum. You leave yourself open to someone using that to clone your phone. -Jay
Unfortunately, in case of the 6820 a USB cable won't cut it — a special FBUS cable & hardware (read: expensive) is required for unlocking. Let's hope the OP unlocks it on the final try...
