the problem is not that they changed the password,its that they locked the modem.i have the pass for that phone but not going to post it,you can use the default to some extent.
but what you need to do is downgrade the modem back to the 4.1.1 or before,i wouldnt go to far back if you want to stay fast and problem free.
then the phone will take your pass again.
