Not quite understanding the issue you are having now. You say you successfully installed the custom 4.1 right?

yup! but i got stucked on the apple logo after the installation...

anyways i got it working! yey!

here's what i did.
1. turn off the itunes
2. create a new cfw then proceed to dfu mode folowing the pawnage
3. after entering dfu, i start the itunes then i restore using the cfw i created
4. the fone restarts then but got stuck on activation.
5. since the fone was foreign, i cannot activate the fone. what i did was i run the limera1n.
6. after the fone restart it was hacktivated already! now for the unlock!!! thanks!!

hope this would be helpful to others in the future!

mabuhay ang pinoy! yeah boi!

You probably shouldnt have run limera1n over a custom firmware. You should have just chosen to activate the custom firmware when you were making it. In any case glad it is working for you.
