After trying various way to get my step sons 3D to go from OMJ 2.5 to 2.7, I got too frustrated and just relocked it and left it at that. Going through Zedo's videos I came across this one and having used his method to unlock the phone before, I just followed it again to unlock it and then to add OMJ 2.7 to the phone while still being S-ON. Previously I tried to flash the 2.7 through another recovery and it wouldnt go through, thats why I was looking to downgrade the 3D and having issues with Office 2010 I couldnt open a program for the CD live kit. I can say now the phone is on 2.7 and everything is working great. Looking forward to adding the ICS from OMJ. I hope this will help others who were like me and didnt downgrade to 1.4 in order to update ROMs.
