it's really hard to tell given the situation
hmmm, i always wanted to write up a quick guide about this issue, but it would be useless since i don't have much to work with
Considering the chain of events, take it to Nino Stores - he will remod it, to LT3.0+ - you will also have to buy the backups reburned with an iHAS burner - As far as i can tell, Nino burns all his
NEW games with it (i told him about an issue he had some month ago where his backups weren't working for some, dunno if he fixed it like i told him to)
It will cost you 50$ since it's your first time - i know it sucks, i would do it for you but i lack the hardware to do it, and shipping it to Lebanon will cost even more (that's if i can get it past customs)
Anyway, take it to him, and tell him the chain of events that happened - he'll know what to do.
