Basically what happened was my phone was in my pocket and it locked itself out. I had pattern lock enabled so i was getting "Too many pattern attempts. please login" No matter how i put my information in username (by itself), firstname.lastname@example.org, email@example.com it wouldn't authenticate me. The first time it happened to me i posted the following thread:
No matter what i did i was not able to get in so i just reflashed the phone. After a reflash the authentication worked fine. At that time I was using one of JFs ROMS so i figured that may have been the issue. Recently the problem happened again. This time i was using one of Cyanogens ROMS. This time instead of flashing the phone i followed haykuro's thread to defeat pattern lock:
once i did those adb commands and rebooted the phone it asked to authenticate again but this time it worked! After it authenticates it will ask you for a new unlock pattern. And you're all set! hopefully it works for you. This is a really annoying problem and im surprised more people aren't having it.
