Ok..it took me a while. I went thru the many xda (oh! the drama) threads and tried a couple of ways.
First I tried 3282 a few times. No dice.
I then tried 786 and went right into a boot loop. I discovered (and others mentioned in threads) this will probably happen using clockwork recovery.
So I flashed RA and tried again 786 (I was using the OMJ deodexed with stock kernel). No dice.
I then saw a few people had success in using
netarchy's stock rooted odexed rom,
so I flashed that.
I tried 786 again with the recommended wipes (one or 2X each). No dice.
Then I saw some folks had success with NO WIPES. So, I did 786 once more time, it went into recovery, I rebooted.....SUCCESS!!!!
Summation: YMMV but I got it on first try using RA recovery, netarchy's stock rom, 786 method & no wipes. Also, on reboot I did not touch the phone at all until it had done it's thing (other than pressing ok at the 3 prompts).
Good luck....and now onto the new OMJ.
