forgot to flash to update for VZW

[trdspectacoma]

Hi people, I just got the TP, I unlocked it, then went to MightyRom 6.5.

Question: I wanted to get the option for Agps, but I think it only works with the new updated Rom from VZW.
How will I go and get that option.

1)flash to the leaked rom.
2)Lock the device
3)flash to the new update from VZW
4)Unlock
5) Flash to MightyROM again

Is my thinking correct


sorry for the newbie question. just don't want to run the chance of bricking the new phone.
