hey man!
i had the same issue when unlocking mine. here it is: do you get warning messages saying "are you sure you want to install this app blah blah blah" when opening new .CAB files? you do? this is it!
next time you get your tp connected just press "update" button on your pc/laptop and keep an eye on your device. when it gives out the message press "yes". bingo! you got it started. the percentage scale reaches 0 - you're done. make sure the bootloader shows cmonex before flashing. mightyrom6 is an awesome choice!
p.s. no need to relock unless you have warranty problems. unlock just once. here we go
