What gets me stumped is that I didn't change that much in the basic operation since the early versions. Now I submitted a new beta (v1.05b1) to the play store - should be visible within a few hours.
Please see if this would unlock your phone. I reverted as much as I could, if this works, we can try successively to see what setting causes it not to unlock. If it doesn't I will take out all the new stuff.
Please try with Fight for mic on and off, although technically FFM off is closer to what v1.02 did.
You know you have to enable beta versions to receive this (please read the intro description above)
