Super Challenge for any TP2 masters

[MysticThunder]

Okay; so, about a month or two ago i posted a thread asking for help recovering my phone from a rogue "lock" screen.
I've had really crappy phones since this bizarre attack from my tp2, and am now losing my patience and would like to return to my best working phone- regardless of what information i have to lose.

Now, heres the challenge;
everyone i talked to at USCC said i was screwed- they tried every reset code they had. Nothing worked- it always rebooted to the same "lock" screen. Im ready to do whatever it takes to kill this horrible lock screen-

is there a way to erase everything- i mean EVERYTHING- on the phone and start over, without being able to get into the UI?

Would flashing the rom or some such thing help with this?
