So I just bought this used Decoy but it was not factory reset before I got it.The ESN/IMEI checks as clear so I'm fairly certain it's not stolen. Trying to delete any contacts results in the 4-digit lock screen appearing, which has been changed from the default "last 4-digits of your number". I'm assuming the seller has no clue of the needed 4 digits (hopefully I'm wrong, but they have yet to reply to my email). I did attempt a hard reset using the 1809#*101# and 2945#*101# but that now just brings up the authentication message and to call #8899 when I attempt a call. For yet another wrinkle I'm not a VZW customer, I'm on an MNVO, but I haven't yet added the phone to any plans.
Is it possible to finish the hard reset this phone by myself through the CSRep. at #8899? Or can I get some supersecret PIN lock bypass instead of blind dialing 0000-9999?
