Default Tmobile early termination fee program

Not sure if this is correct place to ask, if not please forgive. Was wondering if anyone currently with T Mobile used their ETF pay off program? If so, did anyone trade in a rooted/ unlocked bootloader phone? Was there any problem? Do they even pay attention? Have a Note 2 currently with Verizon unlocked bootloader and wanting T Mobile. Any light she'd Is appreciated.
