Update: Forget the other ways, this one worked better. And can use CWM to do it.

Least now it tried to connect I guess cause with the ATT card it finally asked me for the unlock code. However even with ATT and Tmobile simcard, still gives me the invalid sim card. It searches and displays the networks tho.. just never connects, guess this phone is defective. Either way, link above is great for restoring it all. =)
